Rinnai training courses for September/November

More dates have been added to Rinnai UK’s 2016 training programme to cater for the increasing number of engineers and specifiers turning on to the energy saving benefits of gas fired continuous flow water heaters.

Rinnai has seen a massive increase in interest for its complete and comprehensive range of highly efficient ErP labelled A-rated continuous flow water heaters. The company supplies models from the smallest domestic unit to super-size industrial appliances, and since the introduction of energy labelling, demand from engineers for training on the Rinnai Infinity range has rocketed.

The demand has led Rinnai, which believes in making it easy for professionals to experience hands on training with its technologically advanced product, to schedule a new tranche of tailor-made, flexible courses that allow engineers the opportunity to explore at first hand the practical and energy saving benefits of continuous flow gas fired water heaters and to familiarise themselves with the technology.

Rinnai training specialist Ian Jenkins says: “Since ErP, enquires for Rinnai Infinity units have increased exponentially as the transparency of energy labelling allows specifiers and end users to compare products and make an informed choice. As a result of this surge in interest, so far this year we have trained 66% more engineers. These have included our bespoke courses designed to fit in with the modern time demands for professionals. We have also seen a large increase in CPD modules all over the UK.”

“The most popular course modules are ‘Understanding ACOP L8 and hot water system design’ and ‘System design incorporating continuous flow and renewables’,” says Jenkins.

The hands-on training events are aimed primarily at engineers and facilities managers, and cover both traditional and new technologies for commercial water heating and highlight the considerable energy and monetary savings that can be achieved by installation of a continuous flow hot water system.

Courses can be arranged to suit individual requirements either at Rinnai’s Runcorn, Cheshire HQ in the dedicated training facility or if preferred, Rinnai will take the module to the customer’s workplace or other venue convenient to delegates.

Since August and up to October Jenkins has organised a course every week for Gas engineers as well as catering for the needs of other customers and consultants in the private and public sectors.

The additional course dates announced by Rinnai for engineer training are:
27 September and 27 October, 24 November: ‘Service and fault diagnostics (Water heaters)’. These courses are open to engineers, are free, and available at Rinnai’s Runcorn HQ.

The comprehensive engineer training course line-up for 2016 includes nine modules: Rinnai product overview; Continuous flow and the future of water heating; Intermediate water heater; Continuous flow – Excellence in design; Service and fault diagnostics (Water heaters); Service and fault diagnostics (Energy saver warm air units); Understanding ACOP L8 and hot water system design; Maximising renewable gain in hot water design; and, Continuous flow as an innovative method of satisfying energy and regulatory demands.

CPD Roadshow courses are also available, designed by Jenkins for M&E consultants and specifiers, design and build engineers, facilities managers and gas contractors. These courses have already attracted praise from CIBSE. For example, it says of the CONTINUOUS FLOW WATER HEATING SYSTEM SIZING AND DESIGN course: “The course delivers what it outlines and is well constructed.”

“As demand for the A-rated Rinnai range continues to grow, our flexible training ensures key market personnel at all levels, nationwide training from our highly skilled team of technical experts, guaranteeing expertise with the products both for specification, system design and installation. The courses also ensure delegates will be up to speed with any changes in legislation and product developments,” says Chris Goggin, Rinnai UK Associate Director.

RWC UK launches new TIU CPD

Reliance Worldwide Corporation (UK) Ltd (RWC UK), the leading manufacturer of water control systems and plumbing solutions, has launched a new CPD seminar focusing on the use of Thermal Interface Units (TIUs), approved by three professional bodies.

The new seminar ‘Understanding the use of Thermal Interface Units within Community Heating Networks’ has been specifically developed for consultants, specifiers and architects involved in designing heating and hot water systems in commercial or domestic premises, and is approved by CIBSE, RIBA and The CPD Certification Service.

Lasting around 45 minutes, the session examines how a network with individual property heating and hot water systems might be constructed to take advantage of the latest TIU technology. Delivered by members of RWC UK’s technical and sales teams, the seminar explains the features and benefits of such systems and provides building professionals with advice on key considerations and requirements for specification.

David Craven, Key Account Director at RWC UK, explains: “The specification of TIUs is becoming more popular, especially in the design of multiple-occupancy buildings where their use brings significant benefits. For example, installing TIUs reduces material costs and maintenance thanks to the absence of copper pipework and flues. They also remove the need to conform to Gas Safe or FGAS regulations in each dwelling.

“This is exactly what our new CPD aims to highlight; the simplicity and flexibility of community heating networks and TIUs. The session is also free of charge and for the convenience of our customers, we’ll visit their premises to deliver the presentation.”

In 2015, RWC UK introduced the first major brand of UK designed and manufactured Thermal Interface Units to the market with its Radiance® range, made at the company’s head office in Evesham, Worcestershire. Just this year, the range was recognised by two industry awards, being shortlisted in the H&V News Awards in the Innovative Products category, and receiving the Highly Commended in the Innovative Product of the Year category of the Northern Ireland Plumbing and Heating Awards.

The silent scream

Juliet Woodcock talks to Paul Barrett, Product Manager at ROCKWOOL Ltd, about acoustic issues in commercial and educational buildings.

These days within my local library, there seems to be no issue regarding offering overspill space to the neighbouring crèche and play group, gathered in loud restless circles containing a dozen or more exuberant infants. However, there was a time when such municipal facilities demanded a peaceful environment for reading or cultural enrichment, while the stern voice of a librarian calling “Quiet please!” quelled noise in an instant.

Intrusive noise coming from without as well as within is a fact of modern life, though fortunately, there are companies out there that do care about creating a peaceful environment for us to live, work or learn in, as Paul Barrett – Product Manager at Rockwool, explains: “Acoustics in commercial and educational buildings matter. It’s imperative that ambient noise is kept as low as possible to minimise intrusion and distraction in these environments. It’s no surprise that studies consistently show that quieter classrooms and workplaces achieve better results. Unfortunately, a large number of schools and office buildings in the UK suffer from poor acoustics.”

Paul Barrett asserts that the most serious issue regarding poor acoustics is caused by flanking transfer, and went on to explain: “The noise is transmitted indirectly via paths such as external wall cavities, voids above partitions and internal corridors, or where there are problems of excessive reverberation within the rooms themselves.”

But it is not just the internal environment that should be considered when trying to improve a building’s acoustic performance. Indeed, when refurbishing or specifying a new school or commercial premises, plans to reduce the noise from outside from wind, rain, hail and traffic, as well as playgrounds and sports centres should be included.

Stone wool insulation is renowned for its excellent acoustic properties, its open fibrous structure making it ideal for absorbing and regulating noise in the building for the lifetime of the property.

Paul Barrett continues: “It is also incredibly versatile, with products and systems available to suit a wide variety of building applications. These include metal and standing seam, flat, green and pitched roofs; ground, exposed and separating floors; internal partitions and separating walls; fire protection and fire stopping; HVAC and masonry cavity walls.
“Fully tested to meet the rigorous demands of today’s legislation, stone wool insulation solutions are proven to reduce ambient, impact and reverberation noise in educational and commercial buildings.”

Utilizing ROCKWOOL’s HARDROCK® Multi-Fix (DD) product on a flat roof, for example, as a 0.25W/m2K single layer or 0.18W/m2K dual layer, mechanically fixed roof solution can provide an acoustic performance of Rw 35dB (single) and 39dB (dual layer) and Class C sound absorption. HARDROCK® Multi-Fix (DD) also provides an impressive fire safety rating as a flat roof board insulation with a Euroclass (A1) non-combustible fire classification and LPCB approval (LPS 1181: Part 1 (Ext-A).

My local library was the last bastion of peace and quiet in my town; I used to know I could go there and get away from other people’s noise – including my adorable nephew’s teething tantrums. I would feel rested there, browsing through books, and in the early days of my journalistic career, going through the micro-fiche with the librarian to order tomes for research that would arrive up to six weeks later pre-Internet days ….. Good acoustic insulation in buildings is vital to our health, our capability to work and learn.

Rinnai: a gas-fired range of space heaters

Rinnai’s Energysaver range of fanned convection powered flue gas-fired space heaters are designed specifically for use in schools, community centres, libraries, conservatories and churches and other large spaces, where they have earned themselves great popularity with end-users and installers.

Now, with a new super energy efficient addition to the range in the form of the Rinnai Energysaver 559FT with sleek good looks, and a matching new streamlined look for the popular Energysaver 309FT, Rinnai is leading the field in large interior space convector heating.

Sporting a modern, sleek casing, the heaters simply blend into the background in line with modern demands for modern interior aesthetics while offering exceptionally high efficiencies in operation and reduced running costs.

Changes have been made to the operation board which is now an easy to use touch control pad sited conveniently and discreetly on top of the appliance, (rather than on the front with a flip up cover). The unit is also supplied with a child lock to eliminate any problem of small hands tampering with the controls.

Added to these advantages are the timer function and eco mode which are combined with the new unit’s ability to heat spaces fast.

The 559FT has an input of 6.4kW and output of 5.2kW. The streamlined unit measures 554mm x 750mm x 250mm.

The Rinnai Energysaver 309FT, like the 559FT, sports a similar sleek casing and turns in net efficiencies of 88%.

It has an input of 3.4kW and output of 2.92kW. The streamlined unit measures 695mm x 465mm x 257mm. Natural Gas usage has been pegged at 0.31m3 while LPG consumption is 0.26kg/hr.

Also available is the Energysaver 1004T with its impressive 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.

Like the Energysaver 559FT and 309FT, the 1004T 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 largest 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.

Rinnai Energysaver range delivers energy-efficient and consistent warm air powered by Natural Gas and LPG options and is built with fully modulating burners so heat output and energy input is reduced as the space warms up.

The Rinnai Energysaver range comprises fanned convection-powered flue models that exceed seasonal thermal heating guidance under Building Regs Part L.

In a building with high vaulted ceilings, with conventional convector heaters the heat will immediately rise to the ceiling. With the Energysaver range Rinnai has successfully come up with a solution that heats from the floor up and by modulating gas usage in relation to room temperature, provides unparalleled levels of comfort combined with efficiency.

Polypipe Ventilation achieves hat trick success at coveted product awards

For the third year, Polypipe Ventilation is pleased to announce its win in the Housebuilder Product Awards Best Services Product category; this time for its Domus Green Line, High Efficiency rigid duct bends. The company won the award in 2015 with its Domus Radial duct system and in 2013 with its Silavent Green Line HRX Mechanical Ventilation with Heat Recovery (MVHR) system, whilst in 2014 it was highly commended for its Domus Thermal duct system.

With the move to more energy efficient air tight homes, effective ventilation in residential developments is an important necessity. This has helped evolve whole house, mechanically driven systems such as MVHR. However, if these are to perform efficiently, ducting needs to be an air-tight, quality end to end system, such as Polypipe’s Domus rigid duct systems.

The Green Line High Efficiency rigid 90° duct bends are the latest addition to the Domus range. They provide up to 60% reduction in resistance to air flow within the bend, significantly lowering a duct system’s total pressure loss and therefore overall energy usage. When used as part of an MVHR system, this can also lead to cost savings as certain properties may be able to use a smaller unit than previously possible.

The unique design of the Domus Green Line 90° bends results in reduced air speed through the bend, thus lowering system noise as well as smoothing the air flow, thereby helping to achieve higher air flow rates when required. All of these factors improve home owner comfort as well as making central ventilation systems easier to specify.

Domus Green Line High Efficiency 90° bends are available for use with Polypipe Ventilation’s best selling Supertube 204x60mm and Megaduct 220x90mm rectangular rigid duct systems, ideal for whole-house ventilation applications which require higher air flow rates.

The Housebuilder Product Awards were held at Edgbaston Stadium on the 29th June, where the winners were announced. Steve Heeley, General Manager – Director for Polypipe Ventilation comments, “I’m absolutely delighted we have won this award. It’s testament to the hard work, innovation and desire to advance the ventilation industry that exists within the business”.

Domus ducting has a deserved reputation for quality and excellent technical support, in line with Polypipe’s position in the ventilation market. Polypipe Ventilation is well placed to offer immediate, practical solutions to Building Regulations Parts F & L. The company continues to provide differentiated solutions in the private and social housing sectors, transforming the way developers, specifiers, installers, homeowners and distributors meet emerging environmental standards.

Intelligent home air solutions with Polypipe Ventilation’s new HRX-aQ MVHR systems

Polypipe Ventilation has announced its next generation of Mechanical Ventilation with Heat Recovery (MVHR) appliances – the Silavent HRX-aQ, which intelligently manages air conditions for maximum homeowner comfort, whilst also being easier to design-in.

Properties come in different design styles, fabrics, locations and orientations, all of which have an impact on their thermal behaviour. Furthermore, occupants’ comfort levels can vary significantly, with one person’s comfortable temperature being another’s overheating point. The HRX-aQ has been designed by Polypipe Ventilation to take these factors into account, matching ventilation rates to the internal environment and occupants’ requirements for maximum comfort, whilst also being the quietest and most compact Silavent MVHR unit available.

This is achieved through advanced AMIE (Air Management for Indoor Environments) technology including features such as digital humidity control, automated summer bypass and accurate system balancing.

Unlike conventional humidity sensors, the HRX-aQ enables occupants to have direct control over managing the humidity levels in their home to suit personal comfort levels. By accurately measuring air humidity, the HRX-aQ’s extract speed automatically changes from background to boost as the level of humidity increases, thereby providing optimal ventilation performance.

Similarly, the HRX-aQ features advanced bypass control, programmable by occupants based on time or temperature. In standard mode the MVHR units work by warming fresh air drawn into the building using the heat from waste stale air extracted from the kitchen and wet rooms. In conjunction with multiple time controlled bypass options (night time free cooling), the HRX-aQ also detects when the air temperature reaches a pre-set level and intelligently activates the bypass mechanism allowing in cooler, fresh and filtered air.

Control of these features is achieved via a compact Bluebrain control, which also provides homeowners with helpful maintenance reminders for cleaning and replacing filters to ensure performance of the unit is maximised and air quality maintained.

From just 199mm in depth the HRX-aQ MVHR unit is the smallest Silavent ceiling/void mounted unit of its type and weighs down to just 7.9kg, making it compact and light enough to be easily installed in the most restrictive of ceiling voids. This is particularly important for many new build developments where space is at a premium. The unit which incorporates 204x60mm off-set socket connections, can be simply designed-in with a straight in-and-out duct run, making the specification and design process much quicker and simpler. This also enables any duct crossover to be more easily designed and allows the unit to be directly fitted to Polypipe Ventilation’s Domus 204x60mm ducting, for an air-tight connection.

The HRX-aQ is also exceptionally quiet. With background (normal) ventilation down to 24dB(A) (typically no louder than a whisper), the HRX-aQ is one of the quietest MVHR units in the market. Manufactured from high density EPP (expanded polypropylene) material for optimum sound reduction, combined with integral flow straighteners for reduced internal resistance, the highly efficient HRX-aQ ensures that break out and induct noise is minimised.

As with Polypipe Ventilation’s previous Silavent MVHR ranges, the new HRX-aQ remains extremely efficient. When used with a kitchen and one wet room, at typical installation, the HRX-aQ provides an 88% heat exchange performance and boasts a very low Specific Fan Power down to 0.66W/(l/s).

There are eight HRX-aQ models available to suit a wide range of residential properties, including units with a specialist heat exchanger technology to further improve air quality and provide comfortable humidity levels. HRX-aQ ‘Total Heat’ exchangers will not just extract wasted heat from wet rooms but also the latent energy in the humidity. By specifying this heat exchanger, the HRX-aQ will become an Energy Recovery Ventilation (ERV) system, allowing optimal air comfort.

These specialist heat exchangers will also remove the need for a condensate drain; providing extra flexibility on where to site the unit.

Through a process called diffusion, the HRX-aQ ‘Total Heat’ technology allows for the exchange of heat and optimum levels of moisture to be transferred, so that the incoming air is able to harmoniously react with the home environment – whether it be summer or winter.

The Silavent HRX-aQ has been designed to work most efficiently when used with Polypipe’s Domus duct systems, including its new Flow Control Plenum and High Efficiency Green Line Bends, which reduce duct bend resistance by up to 60%. Domus duct systems offer improved system performance through the exacting tolerances and engineered fit of the system, whereby pressure drops are minimised and air leakage virtually eliminated.

Polypipe Ventilation has a well deserved reputation for quality, supported by excellent technical support, from a market leading manufacturer and designer. It is well placed to offer immediate, practical solutions to Building Regulations Parts F & L. The company continues to provide differentiated solutions in the private and social housing sectors, transforming the way developers, specifiers, installers, home owners and distributors meet emerging environmental standards.

For further information on the Silavent HRX-aQ MVHR appliances, please go to www.bluebrain.co.uk or call on 03443 715523. Polypipe Ventilation’s full range of systems can be seen at www.polypipe.com/ventilation.
