Energy savings for Bristol family with EWI by Saint-Gobain Weber

weber.therm XM External Wall Insulation ( EWI) has been installed on a two-storey end of terrace, privately owned property in the Brislington area of Bristol. This is just one of several upgrades being undertaken by the homeowner which have included the addition of a large extension to the side of the property; a loft conversion; the addition of a garden room to the rear and new windows and doors throughout.

“We bought this 1960s property knowing that a substantial makeover was needed and being in the construction business I could see the potential and have managed a lot of the work myself,” says Mark Holden, property owner. “The property was unattractive, even ugly, with hard to treat solid walls, and it was cold. We wanted a more attractive home and greater comfort for our young family.”

The application of BBA accredited and Energy Saving Trust listed weber.therm XM EWI was carried out by M P Plastering Limited, Somerset, renowned for excellent render application skills and experienced with use of the weber.therm EWI systems. The couple sought Green Deal funding with the help of M P Plastering, a Green Deal certified applicator, and successfully achieved a 75% contribution toward the £9,000 cost of the EWI project.

“The Green Deal funding was surprisingly easy to achieve,” says Mark Pickthall, M P Plastering, “which is just as well considering how cold the house was and that there was a young family to keep warm. The property looks completely different now with the application of Weber’s EWI system. We like everything about Weber from start to finish. Great representation, excellent technical support, industry-leading warranties and products that are consistently reliable.”

The weber.therm XM EWI system used on this property included 90mm thick expanded polystyrene (EPS) insulation which was mechanically fixed to the outer skin of the wall substrate. The render process requires two passes of weber.rend LAC, a cementitious render into which the fibreglass reinforcement meshcloth is embedded to give a robust render coat. When dry the surface is primed with weber PR310 in preparation for a 1.5mm thin coat decorative finish of weber.plast TF, an acrylic based, pre-mixed, textured finish, in Winter White. The porch has been finished in weber.pral M one-coat, through-coloured monocouche render in Chalk. weber.therm XM EWI is capable of substantially improving the U-value of a property in a retrofit project, and produces exceptional levels of energy efficiency on new builds.

“Where I had made additions and re-modelled the internal space the external walls were in an awful state. And from an aesthetics angle, it was great to cover the whole exterior with EWI. We can no longer see the scars and joints,” continues Mark. “Work started at the coldest time of year in November 2014, but within weeks we were feeling the benefit of the EWI. During a particularly cold spell we found there was no need to switch the heating back on after the timer programme had lapsed each morning which would have been necessary previously.” By February the property was fully wrapped and rendered.

“The massive visual improvement to our home is quite amazing,” says Mark, “but the saving we have made on our monthly fuel outlay is incredible. From an average of £150 per month during the winter months we are now paying around £80 a month, that’s a very big saving for a family.”

“We have carried out many projects on this property and my wife and I agree the EWI application has been by far the most successful element of our plans.”

Weber products are manufactured from carefully selected raw materials at purpose-built facilities in Bedfordshire, Shropshire and Ireland where quality and consistency is achieved.

Rinnai space heater excels in energy efficiencies

The Rinnai range of Energysaver fanned convection powered flue gas fired space heaters offers the highest efficiencies on the market.

The range has been designed specifically for use in schools, community centres, libraries, conservatories and churches and other large enclosed spaces where they offer exceptionally high efficiencies in operation and contribute to drastically reduced running costs.

The Energysaver 1004T has an input of 11.6kW and outputs 10.23kW. Its measurements are 670mm x 930mm x 315mm and it has energy efficiencies of 96% under the guidance of Part L 2014. This puts it in the top rank of space heaters in its class.

It provides safe, controllable heat with maximum energy efficiency, combined with flexibility of location.

The heater is also suitable for central timer control. This feature allows the building manager to run any number of Rinnai space heaters off a central time clock providing heat to the large of spaces. The Energysaver Multi controller is not limited to single Energysavers as the flexibility of the system guarantees units can be mixed and matched to satisfy even the most unique of buildings.

The units are encased in a low surface temperature (LST) casing to avoid any risk of burns and offer easy on/off operation and intelligent features such as self-diagnostics and a self-learning pre-heat time to maximise heat up time and energy consumption. Warm air is delivered at floor level for greater comfort and coverage of even greater spaces.

Rinnai Energysaver units are very easy to install as there is no need for expensive (and extensive) ductwork, nor do they involve to running heating circuits for radiators or pipework to boilers. This cuts down drastically on cost and time at the point of installation.

The Rinnai Energysaver 1004T delivers energy-efficient and consistent warm air powered by Natural Gas and LPG options via fully modulating burners so heat and energy input is significantly reduced as the space warms up.

“Rinnai energy saver space heaters really do deliver a cost saving on installation, low operational costs and maintenance, lower life cycle costs, lower replacement costs, high energy efficiencies. They are infinitely suitable for refurbishment projects and, due to Rinnai’s confidence in the superiority of its engineering processes, they come with a 15-year warranty on the heat exchanger,” explains Chris Goggin, Associate Director of Rinnai UK.

The Rinnai Energysaver range comprises fanned convection-powered flue models that exceed seasonal thermal heating guidance under Building Regs Part L, while also heating the usable space within buildings, ensuring comfort, efficiency and compliance.

New commercial chemicals optimise system performance

Fernox has launched an enhanced range of commercial chemical water treatments, which includes: FC1 Inhibitor, FC3 Cleaner and FC1 Filter Fluid+ Inhibitor. Specifically designed for larger commercial systems, the three new products provide contractors with the high quality and reliable solutions needed to maintain energy efficient heating systems and protect vital system components from breakdown and failure.

Featured within the range is the universal, powerful FC3 Cleaner. Its formulation has been designed to purge commercial systems from harmful sludge and debris and restore the efficiency of existing systems. The effective product is also ideal as a pre-commission cleaner for new installations and suitable for use when conventionally flushing.

Once the system water is clean, the best-in-class FC1 Inhibitor should be utilised to protect against limescale build-up and corrosion formation. The FC1 Inhibitor is a proven formulation that is left within the system to maintain system efficiency and extend component longevity.

In cases where conventional flushing is difficult, not practical or even where high pressure powerflushing could create further system problems, then the unique FC1 Filter Fluid+ Inhibitor is recommended. The product combines the proven effectiveness of F1 inhibitor with an active dispersant package to detect, lift and deliver contaminants to a system filter.

For example when used together, FC1 Filter Fluid + Inhibitor and the TF1 Delta Filter will continuously protect against circulating debris that could cause system damage or breakdown – working to restore system efficiency. This complete solution mitigates the need for a system shutdown.

Also featured within the commercial chemical range is the popular Alphi-11 Antifreeze Protector. With proven capabilities and a reliable performance, the product is both non-toxic and compatible with metals and materials commonly used in heating systems. Alphi-11 can be left in the system all year to prevent frost damage and freezing pipework to temperatures down to -22 ̊C. Additionally, the combined antifreeze and inhibitor package avoids the need for a winter drain down and prolongs system life.

“Commercial heating systems are vulnerable to the build-up of sludge, scale and corrosion, all of which not only has a detrimental effect on system performance and carbon emissions but also affect the longevity of the system,” said Francine Wickham, Global Marketing Director at Fernox. “Our complete range of chemical water treatment and filter technology allows contractors to maximise the energy efficiency of commercial systems and protect vital and expensive system components from premature breakdown.”

FC1 Inhibitor, FC3 Cleaner and FC1 Filter Fluid+ Inhibitor are available in 20 litre packs and Alphi-11 Antifreeze Protector is available in a 25 litre pack.

Nexus Brick Faced Support System

Creating flawless brick-faced soffits and lintels has now become much simpler and quicker, thanks to a new lightweight stainless steel based system developed by two industry-leading companies – brick support specialist Ancon Building Products and Ibstock Kevington –national manufacturer of brickwork and masonry special shapes and prefabricated components.

The new Nexus® system combines a specially developed Ibstock Kevington lightweight brick-faced steel unit with Ancon’s tried and tested MDC stainless steel bracket angle support system. The system offers contractors easier handling coupled with maximum adjustability, both vertically and horizontally, for quick and simple alignment on site.

The new system offers considerable benefits over traditional cast concrete alternatives – cutting weight by more than half, which in most cases will allow the brick-faced units to be installed without specialist lifting equipment, and significant savings in installation time – making it particularly appropriate for fast-track or time-limited projects.

Individual Nexus® units are designed and prefabricated off-site to suit different soffit dimensions, even modern deep soffits, so there is no cutting required on-site. They are simply offered up to the pre-fixed and pre-drilled Ancon MDC support system and then bolted into position using T-head bolts. The quality design allows units to be simply adjusted for perfect alignment and, once in position, all that is left is for the brick facing to be pointed for a seamless match with the main brickwork.

Nexus units can be fabricated using virtually any brick or masonry with the chosen product being specially selected and precision cut, generally from the same batch as the main façade to ensure a perfect visual match. Various brick patterns can also be specified to match individual project designs and styles.

All system components are of the highest quality, and engineered for economy and durability, with slips permanently bonded to the high grade stainless steel Nexus system using a BBA accredited bonding system. Nexus has been independently tested for long term durability by Lucideon, the independent global experts in materials testing, analysis and consultancy.

Ibstock Kevington Sales Director, Warren Dean said “Nexus® is an exciting new development that brings together the combined experience and expertise of two major companies – each market leaders in their own area. The advanced design will not only make it easier and quicker to specify and install modern brick-faced soffit and lintel features in a range of different building applications, but the two-part design means it will be far easier to achieve perfect alignment with the main brickwork façade.”

Further details and technical specifications for the Nexus® system are available in a new 4-page brochure, available to download from www.ancon.co.uk/Nexus.

Alan Thomas, Kiwa BDA Associate explains why the BDA Agrément® is

Specifiers, distributors and contractors know that it makes sense to avoid problems with acceptance of products or systems on site by building control, NHBC or simply astute customers. If the products they are considering specifying, supplying or installing are traditional or well-established they could select those which comply with British, or increasingly these days, European Standards and that are CE Marked (if appropriate). Additionally, building envelope products should carry approval by an independent body accredited for the task, showing that the product is fit for purpose.

Independent third party approval removes barriers to acceptance of all relevant building products by bringing together all the critical material properties and installation requirements in one common format reference document.

Kiwa is an international independent certification body with a pedigree of many years, and unrivalled experience in developing certification guidelines for a huge range of innovative building products, and has state of the art laboratories across Europe to test them. It is now extending its Kiwa BDA Agrément® scheme within the UK, developed on the basis of over 30 years’ experience on the study of the building envelope. With UK offices including Cheltenham, Harrogate and Derby, Kiwa is UKAS accredited and a Notified Body under the CE Marking arrangements applying across Europe. BDA Agrément® is fully recognised by the NHBC as meeting their technical requirements and by LABC for Building Regulations purposes.

BDA Agrément® is aimed at confirming the fitness for purpose of products covered or not covered by British or European standards and involves a thorough and rigorous assessment of the product concerned involving evaluation of its’ use on or within a building and testing of its’ key performance factors. The assessment also includes factory inspection and audit, to ensure that processes are in place to ensure that the specification of the product will be maintained as long as the BDA Agrément® is valid. Site inspections are also carried out to check installation information and practices and once the BDA Agrément® has been awarded the manufacturer will be subject to annual audit to check that all is as it should be.

Kiwa’s BDA Agrément® has already been awarded to many UK manufacturers, most recently to Kingspan Insulation for its Optim-R Vacuum Insulation Panel.

BDA Agrément® awarded to other UK firms so far include those covering external wall insulation, roof, wall and floor insulating reflective membranes, roof waterproofing and waterproofing to the underside of the raft and the outside of the walls to reinforced concrete earth retained structures.

Most recently the Kiwa BDA Agrément® is now recognised by DECLG – the Irish Government Department responsible for building standards.

Value Engineering – What is it all about?

,

As the construction industry strives to provide the optimum building solution, just how can companies today differentiate themselves and ensure they are offering best value?

Steve Thompson, Managing Director of light steel frame manufacturer, EOS Facades explains how they are using value engineering and Design for Manufacture and Assembly (DfMA) to meet the demands of today’s construction industry.

Value Engineering – What is it?

Today’s customers are savvier, more commercially aware and they expect more for their money. As manufacturers and service providers, we need to react and meet this demand, or risk losing out.

But before we can do this, we need to understand what value really is.

Assessing best value depends on the objectives set – speed of construction, build costs or the development of a sustainable, energy efficient building – or perhaps a combination of all.

Adopting a ‘one system fits all approach’ will not necessarily deliver best value. It is not about economies of scale but it is about an optimised approach – working with the client to select the right solution, at the right price, to deliver the right performance.

Adding Value: Design for Manufacture and Assembly

WEB PIC 2

As a manufacturer of steel solutions, EOS Facades take full advantage of offsite manufacturing techniques by adhering to Design for Manufacture and Assembly (DfMA) protocols. DfMA is now recognised as the foundation for concurrent engineering processes to streamline and fully optimise the structure. The process aids the building design process and helps to identify, quantify and eliminate waste or inefficiency where possible.

At EOS Facades we pride ourselves on driving quality through precision manufacturing whilst delivering accurate results on time and on budget.

We have taken steps to ensure that DfMA is integrated throughout the design and manufacturing process. We have made considerable investment in developing technology to aide specification and design. We are totally committed to working with our clients on product and service innovations to help them gain a competitive advantage in the marketplace – delivering cost and time efficiencies.

The EOS manufacturing facility is a 40,000 sq ft operation that houses state-of-the-art machinery and technology providing offsite systems and solutions that meet the needs of our customers. Our manufacturing facility is well equipped to cater for the demands of offsite construction and precision engineering. Our sophisticated roll-forming machines have embedded framing technology that enables production of self-jigging framing components that are ready for assembly, eliminating the need to manually cut onsite.

All of our products are manufactured under strict quality management control which is fully compliant with BS EN ISO 9001:2008. Our accredited quality management systems and procedures eradicate onsite variability and ensure life time ‘in service’ performance and durability.

Adding Value: Software and Building Information Modelling

Precision built offsite products require the application of leading-edge technology and contemporary manufacturing processes. We have invested substantially in the latest software and hardware systems in steel frame production. Our systems combine the latest E-Frame technology platform with proven assembly processes, providing fully framed panels that do not require jigging.

Sophisticated software transfers building design information directly to our production plant where we are able to manufacture to accuracies that exceed construction industry norms. Once the panels have been designed using our 3D Tekla modelling software, they are directly uploaded to the roll-forming machines, using a bespoke CAD/CAM interface, where they are produced to exact dimensions using CNC technology. Each stud is identified with an inkjet printer to match the assembly drawing and every frame has an identification label attached. This identifies the project, frame number, order number and site location on the GA site drawings so they can be positioned quickly to their onsite location.

Adding Value: Product

Product quality is essential. EOS only use minimum S390Nmm2 G275gsm steel (higher grades and coatings on request). By only using steel with a protective coating and design detailing that eliminates prolonged exposure, EOS are confident in the durability of our systems. Research has shown in these conditions coated steel has a potential life of over 1,000 years.

The team at EOS support key industry standards and strive to exceed expectations on reliability and delivery. All of our products are manufactured to rigorous quality standards which are fully compliant with the Construction Products Regulations – EN 1090-1: 2009 + AL: 2011. Our quality management systems are BS EN ISO 9001: 2008 registered.

Adding Value: Cost

WEB PIC 3

We offer all-inclusive fixed price packages that are uniquely supplied with proprietary brackets and fixings required. All Double Studs/Opening Jambs/Lintels and Sills will be dispatched from our factory preassembled. This is a flexible service and should you require the product to arrive unassembled, EOS will pre-punch in the factory, ghost assemble and supply, together with all the necessary screws and special drill bits, for assembly and installation onsite.

Adding Value: People

EOS Facades are constantly striving to improve the way we work and the resulting benefits are passed onto our customers. Research & Development is a core focus of our business and it is not just down to one specific team, at EOS everybody is encouraged to put recommendations forward, whether this is a process or an alteration to a product – that way every part of our business can be enhanced.

EOS also offer a total partner solution including application consultancy, structural design support and value engineering, as well as quality manufacturing.

To meet the demands, we need people to make the change happen.

Now the construction industry is starting to recognise the shift in needs of the client, manufacturers must ask themselves, are they well equipped to meet demands or will they risk losing out?

For more information on EOS Facades’ products and services visit: www.eos-facades.co.uk

Adding Value: Knowledge Sharing

Shackerley’s engineered stone façades shape up beautifully at Kew Bridge West

Shackerley has demonstrated the extraordinary design potential and versatility of its Sureclad® ventilated cladding systems by supplying innovative engineered stone façades for a challenging installation at Kew Bridge West, an exclusive development of 336 luxury apartments in North London.

2400m² of fully prefabricated Sureclad® engineered stone cladding in a natural limestone colourway and honed finish has provided a premium quality aesthetic for the lower storeys of the nine apartment buildings in this stunning complex, designed by Stockwool and developed by St James, part of the Berkeley Group.

Two circular towers called for smooth rounded façades and Shackerley’s Sureclad® Hang On system had to be customised to cater for large format curved panels, cut to a radius from solid blocks of engineered stone. Additional challenges included the design of elegantly faceted façades to clad curved elevations of adjacent buildings, designed to reflect the development’s ‘horseshoe’ design.

Shackerley and specialist façade installation contractor Stanmore worked very closely together, developing bespoke solutions at every stage, from the design of the Sureclad® façades to the palletisation of the prefabricated system. Stanmore’s installers also visited Shackerley to receive expert training in the use of the Sureclad® system.

As this was the first time that curved engineered stone panels had been used in conjunction with Sureclad®, the companies arranged for the bespoke facade system to be tested to NHBC criteria at VINCI Technology Centre UK.

Stanmore Commercial Director Peter Baker said: “We were responsible for delivering all the external façades, curtain walling, doors, windows and other external finishes on this project but the engineered stone cladding was by far the most highly valued element of the job. Close collaboration with our supplier was absolutely crucial. By planning and modelling the installation in detail and working hand in hand with Shackerley’s technical team, we achieved superb results for our client. The overall experience was very positive and we’re looking forward to working on other Sureclad® projects in the future.”

Construction Director at St James, Brian Paterson, commented: “It was only when we came to value engineer the Kew Bridge West project that Shackerley’s system was brought to our attention. As a result of switching the engineered stone specification to Sureclad®, we’ve undoubtedly benefitted from a more flexible and lighter façade solution than originally planned and from very substantial cost savings, whilst still achieving our architects’ original design intention. We’re delighted with the results”

For further details on the Sureclad® system please contact Shackerley on 0800 783 0391 or visit www.shackerley.com.

Industry first for Sapa with A++ window

The tilt before turn (TBT) window from fenestration systems specialists Sapa Building Systems’ Dualframe 75 Si range is the first aluminium window to be given the new A++ Window Energy Rating (WER), the highest available rating in the UK.

Awarded by the British Fenestration Rating Council (BFRC), the rating was originally launched at the start of June, giving manufacturers four months to develop products. However, such is the future proofing strength of Sapa’s Dualframe 75 Si range, the TBT window was already compliant.

The entire suite of windows included in the class leading range all achieve the A+ WER, the only aluminium range to do so. It has continued to push boundaries since its launch in 2010 and Sapa’s commitment to exceeding energy and security targets set out in the Building Regulations and national standards is underlined in the awarding of the A++ rating to the TBT design.

“We are again leading the way with energy ratings for aluminium windows,” said Mark Robinson, Technical Director at Sapa Building System. “This latest award follows on from similar accolades in 2006 when a solution from the Dualframe 75 range was the first aluminium window to be awarded an A rating, which was then followed in 2013 with the Si A+ WER.

“This new addition to the rating system will not only offer fabricators more choice, it will also create significant energy savings, helping to reduce bills. The TBT window will reduce solar gain in the summer while helping to keep buildings warm in the winter. With the next expected revision of Part L of the Building Regulations expected in 2019, we are ideally placed to be able to meet any projected tightening.”

“BFRC is delighted at the take up for the new A++ rating for windows,” comments BFRC Managing Director Chris Mayne. “Since the announcement that BFRC was accepting applications for the new A++ band we received simulation reports from far more companies than we expected. This has resulted in the launch of the first batch of A++ window products and we look forward to seeing how they perform in the market.”

The Dualframe 75 Si TBT window is an ideal solution for high rise or commercial applications, and combines ventilation with easy cleaning and large span openings. The safety locking handle is key operated and the key must be inserted in order to access the turn mode. Once the window is closed, it automatically defaults to the tilt only mode.

Rinnai – The infinite hot water & space heater solution

Rinnai’s Infinity range of continuous flow gas fired water heaters includes heavy duty and condensing units that are engineered to guarantee high efficiencies and low running costs – and exceed future and current regulations and standards like those proposed by Part L Building Regulations and ERP.

Rinnai is also the manufacturer and supplier of the Energysaver range of space heaters designed for fast and efficient heating. The range comprises of fanned convection-powered flue models that exceed seasonal thermal heating guidance under Building Regs Part L.

And now, new technologically advanced additions enhance the ranges still further.

Rinnai’s heavy duty condensing (HDC) Infinity models

NEW: The latest addition to the range is the Infinity HDC1600i renewables-ready low NOx series, the first heater of its kind to utilise Rinnai’s own patented pre-mix burner technology. The newly developed down-firing burner allows increased efficiency and reduces NOx gases. The Infinity 1600i series is available with an output of 58.4kw producing 16.2 litres of temperature controlled hot water per minute (or 972 per hour) raised at 60°C.

The HDC1200 internal and external models give an energy performance of 107% net efficiency while the larger Rinnai HDC1500 internal and external models turn in 105% net efficiency.

These Rinnai condensing continuous flow water heaters are extremely low NoX, less than 20ppm, with net efficiencies of 105-107% and flow rates up to an excess of 972 litres per hour @ a 60° temperature rise.

Rinnai Infinity bespoke solutions – compliance packages

NEW: Rinnai has devised a bespoke turn-key solution that has now been adopted as the preferred water heating choice for a global fast food chain. The Pack has been designed to provide better on-site efficiency and is supplied to site in bundles, including best in class Rinnai Infinity continuous flow gas fired water heaters and all relevant parts, including scale protection technology where necessary. The pack comes with bespoke installation instructions and schematics inclusive of commissioning sheets for sign off, ensuring a one hit install.

The ERP ready system offers proven 105% efficiency, supports G3 compliance and Legionella (ACOP L8) compliance as well as being best in class under Part L building regulations.

Rinnai Infinity Plus

The Infinity Plus solution for large commercial operations has been developed to provide never-ending hot water without costly storage and brings together multiple units of the company’s award-winning condensing continuous flow water heaters into single, easily manoeuvrable modules.
The comprehensive Rinnai Infinity PLUS range offers specifiers and end users a system that guarantees a constant flow of safe hot water at precisely the chosen temperature. Operated via an easy to use built-in digital controller, the water heater provides near mains pressure flow for as long as is necessary. Rinnai can design these systems to supply in excess of 24,000 litres per hour at 50°temperature rise.

Rinnai Infinity Plus storage

Using a modular system of either internal or external Rinnai HD or HDC condensing water heaters and a stainless steel storage vessel, demands in excess of 20,000 litres per hour can be satisfied. Rinnai Infinity Plus Storage packs represent the best value-for-money hot water storage solutions on the market today with everything delivered direct to site in one complete package.

Rinnai renewables heating solutions

Rinnai units used as a gas booster to solar thermal or heat pump installations. This maximises renewable gains. Rinnai infinity water heaters are the only booster that can modulate from 58kw to 2.4kw ensuring renewable hot water is only complimented by gas. A comprehensive range of renewables products including solar arrays is available.

Rinnai Digital, BMS Gateway and controllers

For commercial buildings, Rinnai’s development and investment in integral smart controls for its appliances makes them compatible with sophisticated BMS system. Rinnai BMS Gateway’s enable the interaction between the water heater and building management systems, allowing easy monitoring which in turn identifies areas where energy is being wasted, error messaging supporting first time repair, trend logging and much more.

Rinnai Solo

NEW: The Infinity Solo condensing low NOX is the first Rinnai product for the UK to combine the advanced technology of its wall mounted continuous flow water heaters with a stainless steel storage cylinder all in one compact footprint.

Because the cylinder is stainless steel it greatly reduces the weight compared to glass lined models, which makes transportation and installation easier. As well as the difference in weight, the cylinders available also have extremely low heat loss figures (as low as 1.5kW/h day), which means the customer pays less to maintain the heat within the tank. The Infinity Solo also has the fastest recovery times on the market these can be as short as 19 minutes.

Common flue header system

Rinnai has also pioneered a common header flue system to streamline manifolded installations of its award-winning Infinity condensing continuous flow gas water heaters. Previously multiple installations in an interior plant room would have meant each unit had to have its own flue and that meant punching a hole through the building fabric for each individual unit, a time consuming and expensive necessity.

Lime scale checker

Another simple but effective idea safeguards against lime scale build up occurring in Rinnai continuous flow water heaters a scale control system continually monitors the appliances for lime scale deposits around the heat exchanger and alerts the end user that it is time to perform a lime scale flush.

Energysaver space heaters

Rinnai Energysaver 559T, 309T and 1004T deliver energy-efficient and consistent warm air powered by Natural Gas and LPG options and are built with fully modulating burners so heat output and energy input is reduced as the space warms up. The units may also be controlled via a central timer for added economy and occupant comfort and are encased in a low surface temperature (LST) casing. The heaters are suitable for central timer control. This feature allows the building manager to run any number of Rinnai space heaters off a central time clock providing heat to the large of spaces.

The Rinnai Energysaver 559T unit turns in efficiencies of almost 92% when you are considering the effective heat generator seasonal efficiency required for UK building regulations. It has an input of 6.4kW and output of 5.2kW. The unit measures 554mm x 750mm x 250mm.

The Energysaver 1004T has an input of 11.6kW and outputs 10.23kW. Its measurements are 670mm x 930mm x 315mm and it has energy efficiencies of 96% under the guidance of Part L 2014.

The Energysaver 309T has an input of 3.4hw supported by 85.9% efficiency making it ideal for smaller light commercial and domestic installs.

HD range

Rinnai has a range of cost effective HD solutions ideal for light commercial and replacement products. The HD range consists of the HD50, HD70E, HD55i and HD55E. The units range from 54kw to 69kw and produce as little as 20ppm NOx whilst having the capability to produce up to 979 ltr/hr at a 50°C rise.

EN 16005 compliance is a click away thanks to logbooqr from GEZE UK

There’s no need to worry about lost or damaged log books again thanks to a new innovation from automatic door and window control systems manufacturer GEZE UK.

The company has developed logbooqr, a new online logbook for automatic doors which can be accessed via a QR code using a smartphone or tablet.

Since the introduction of EN 16005 in April 2013, all automatic doors must have a logbook to keep a detailed record of any servicing and maintenance work that has been undertaken. Currently, an asset tag, detailing a unique reference code, is fitted to the door itself and a physical logbook is issued. This is then completed by service and maintenance engineers as soon as any work is carried out. The problem is that logbooks, that need to be kept with the automatic door, are frequently lost or misplaced.

logbooqr allows this information to be recorded on a secure website which is accessed via a QR code printed on the asset tag. This allows an engineer to record the work that has been done, while the end user can check the log and see when the next service is due. In the event of an accident or random spot check, Health and Safety Inspectors can easily access this information to confirm that servicing and maintenance schedules are up to date.

Speaking about the launch of logbooqr , Steve Marshall, service director of GEZE UK said: “Compliance with EN 16005 means that a log book must be kept for every automatic door, but we frequently find these are lost or mislaid or may not even have been passed on to the end-user who is responsible for the door.

“While losing a log book may seem like a small oversight, in the case of an accident, the health and safety investigator may assume that essential maintenance and servicing has not been carried out. As a formal maintenance record a log book may be called upon in a court of law to prove or disprove liability.

“logbooqr has been designed to provide an easy to access and maintain record of an automatic door’s history. An engineer simply scans the QR code and updates the log, creating an accurate record that can be accessed at any time. And because it’s all recorded online, it can never get lost again!”
