Installing both heat interface units (HIUs) and underfloor heating (UFH) within communal heating schemes is a great way to improve the efficiency of both the primary and secondary systems. Furthermore, this winning combination is now deemed best practice for heat networks, as recommended in industry codes such as CIBSE CP1.

One Bristol based HVAC company, Giacomini UK, has set about making it as easy as possible for construction managers to meet these guidelines. Its team of UK engineers, including CIBSE Certified Heat Networks Consultants, are well-versed in supplying tailored UFH, HIU and flow control packages to communal heating schemes, with the demand for their joint packages accelerating.

Heat interface units are driven by consumer demand, only extracting what they need from the primary system to accurately provide the consumer with the correct amount of domestic hot water or heating. Whilst on the secondary side, the lower flow and return temperatures of underfloor heating enable the boilers to operate at a higher efficiency.

This combination along with flow control provisions, such as differential pressure control valves, will improve the efficiency of the central boiler plant and help to bring the building design is in accordance with current industry guidelines.

One recent project, which combined all three of the above fields of Giacomini’s expertise, was a large residential and work space development in London, which saw over 2,000 square meters of underfloor heating pipework being installed, alongside 31 twin plate heat interface units and several pairs of differential pressure control valves and static balancing valves.

Discussing the increasing demand for combined services projects, Matt Lowe, managing director of Giacomini UK, commented: “In the past, customers largely came to us needing one service but increasingly we are finding that people are recognising the benefits of having all services provided by one manufacturer. Not only does it boost the efficiency of the system as the components are designed to work together, but it also eases installation as all enquiries go through one point of contact who ensures the same high level of quality throughout.”

Further afield, Giacomini has designed joint packages for a variety of communal heating projects including a 60 bed extra care scheme, 34 amenity flats and 85 luxury apartments.

For each project, Giacomini’s team of technical engineers provided guidance on the design of the heat network to make sure it is done in accordance to CIBSE Heat Network Code of Practice CP1. The team is also equipped to advise on diversity, flow rates, velocities, pressure losses and assist with calculating peak demand.

UK’s leading manufacturer launches brochures for interior and exterior uses.

New coffee table-style brochures showcasing Welsh Slate products for interior as well as exterior applications have been launched by the leading UK manufacturer.

Available through www.welshslate.com, the eight-page brochures dispel the myth once and for all that Welsh Slate, part of the Breedon Group, is just about roofing, with stunning photographs proving the product’s versatility for a wide range of uses.

Both beautifully illustrated brochures talk briefly about the company’s quarries in North Wales, including Penrhyn at Bethesda and Cwt-y-Bugail in Llan Ffestiniog, being a focal point for the production of UK natural stone for the past 700 years – the slate’s 500 million-year-old pedigree is reflected in the fact it is still handcrafted.

Although both show the range of colours (Penrhyn Heather Blue and Grey and Cwt-y-Bugail Dark Blue Grey) and finishes (riven, honed, flamed and machined) there the similarity ends.

The exteriors brochure features copings and sills, as used at the ME Hotel in London, walling and cladding as used at the National Waterfront Museum and many prestige private properties, paving, and roofing as used at York Racecourse and St Mary Abbots Church, London.

The interiors brochure features flooring, as used at the British Museum, interior walling and cladding, worktops, and fire and hearth surrounds.

No matter inside or out, the brochures reinforce Welsh Slate’s suitability for a wide range of contemporary and heritage architectural and interior design uses due to its aesthetics, durability and low maintenance.

Gatic, the global leader in access covers and civil drainage systems, recently installed Slotdrain CastSlot Treadsafe, its high capacity surface water drainage at Hamilton Business Park in Hedge End, Southampton. The £2m project, which spans 24,000 sq.ft., involved building brand new industrial and warehouse units and is the final phase of a 30-year project that started in 1988. The business park now has a total of 26 units covering 250,000 sq.ft. and 20 acres of space.

BCT Services worked with the developers to complete the project. John Griffin, buyer for BCT Services, has worked in construction for 30 years and is familiar with Gatic’s products. He comments: “Our specification called for CastSlot but I would have recommended using it anyway. It’s a good product, practical and easy to handle. It comes in three, one and a half metre lengths, which are designed with quick and safe installation in mind, and the metal construction means it’s not liable to breakages – which speeds up installation and improves safety, as well as saving cost.”

CastSlot is part of Gatic’s market leading Slotdrain range, available with a 10mm or 30mm opening and a load classification of up to F900, CastSlot is ideal for areas which are subject to heavy loads and slow turning traffic such as warehouse and industrial units. Its unobtrusive profile sits neatly within concrete, asphalt and block surface finishes, and an electro painted ductile iron throat section is securely fixed to the galvanised steel channel body for an exceptionally robust yet discreet drainage system. The Treadsafe option is recommended for areas where regular foot traffic is likely.

Giacomini, a leading manufacturer of HVAC components, has released an update to its R146M dirt separator valve. This development follows the business’s successful launch of its patented adjustable magnetic dirt separator (R146C) last year.

The new valve has an extended range, and can tolerate temperatures up to 130 degrees Celsius, meaning that the valve is now suitable for medium-temperature hot water (MTHW) systems.

A key market for MTHW systems are large sites, such as hospitals, where process applications require higher temperatures than low-temperature hot water (LTHW) systems can deliver. Due to the functionality of the new R146M valve Giacomini can now fulfil the needs of these markets.

A dirt separator protects the system, and its essential parts, from both magnetic and non-magnetic dirt and debris that can build up over time and circulate through the system. This can cause blockages and hinder the system’s efficiency.

The R146M dirt separator valve further extends Giacomini’s successful flow control range, which also includes DPCVs, Static and Dynamic Balancing Valves, Boiler Safety Manifolds and Hydraulic Separators.

Kestrel Mechanical Services of Sevenoaks, Kent, has recently completed a complete refit of hot water heating systems at a well-known care home in the South East of England.

Kestrel has installed two Rinnai HDC 1500i on Natural Gas and included the unique scale inhibitor protection system. Previously the hot water systems delivery was provided by a whole set of satellite domestic boilers dotted all over the site.

The building is a stunning villa which is a converted private residence that’s been modernised to the highest standards of comfort and practicality. It offers a delightful 50-room residential and nursing home set in three-and-a-half acres of beautiful gardens near the north Kent coast.

The home is made up of two separate buildings that provide very specialist care. Both have the benefit of access to the glorious landscaped gardens – complete with conservatory and patio area.

The care home aims to provide as comprehensive a range of care as possible, so can offer 24-hour convalescent, respite, palliative and frail elderly nursing care.

Regular and stimulating activities are the key for social interaction and general well-being, and that’s why there is a packed schedule of fun activities to do.

A reliable hot water heating delivery system was needed to replace the tangle of boiler units spread over the site.

For Kestrel Julian Ringrose said, “Our brief was to make the hot water delivery system work at an optimal level of efficiency. We chose the Rinnai 1500i units for a whole variety of reasons – reliable & continuous flow of useable hot water, safe temperature water distribution at all tap and shower points, overall energy efficiency and ease of installation plus minimal ongoing maintenance costs. Hot water is vital to the wellbeing of all residents, so we needed to get it right with the right product and Rinnai was the right choice.”

Water temperature is pre-set through easy-to-use built in digital controls, eliminating the risk of scalding and potentially eradicating the need for thermostatic mixing valves. Water can be used simultaneously at several points of delivery with no loss of heat.

The Rinnai HDC 1500i range is designed for use directly off the mains, with no need for large, ungainly and energy inefficient storage vessels -and is capable of delivering in excess of 780 litres per hour at 65 degrees Celsius, therefore ensuring water temperatures ideal for preventing legionella proliferation.

Eco-labelling of products offers transparency to specifiers and end users in a clear and simple guide when sourcing the most energy efficient hot water heating units. And so, the fact that Rinnai maintains ‘A’ rated Eco-labels on all its units speaks volumes for the company’s manufacturing process and stance on supplying only the highest efficiency units to the UK market. Rinnai products also meet and exceed the requirements of the Building Regulations Part L (fuel and power) and with these bespoke system arrangements they can offer G3 and ACOP L8 best practice too.

Any possibility of Legionella breeding is minimised as Rinnai units have no storage and can be cited close to the outlet and therefore limiting the environment for bacteria production. The Rinnai Infinity series HDC1500i/e Low NOx is capable of delivering in excess of 2000 litres per hour. It has efficiencies of up to 107% and can realistically claim to be one of the most efficient hot water heating units of its kind available in UK. The HDC1500i/e Low NOx is an on-demand style hot water heating unit – suitable for natural gas or LPG – and it has NO storage cylinder. This means that there is no needless waste of energy from constantly reheating a stored body of water for when there is demand. Energy is only used on a Rinnai unit when there is demand – simple as that.

There is a big potential of annualised fuel saving costs with a HDC1500i low NoX unit – these costs can be minimised next to any comparable type of storage water heater, such as gas direct fired storage water heater or indirect cylinder system connected to the heating boiler. Contact Rinnai for professional CPDS and studies on this topic.

Rinnai Infinity HDC1500i Low NOx can boost a modulation range of 59.5kW to 2.8kW, and operate at a flow rate of as low as 1.5l/min. Thanks to this high modulation range, the Rinnai units ensure that the optimum amount of energy is used to heat the water, minimising waste and maximising system efficiencies.

The HDC1500i low NoX is extremely lightweight and easy to handle at just 31 kg.

By developing this holistic condensing technology initiative, Rinnai offers a simple, viable, cost effective, and energy efficient solution to any consumer needs for hot water.

Janisol Arte 2.0, the second-generation renovation window from steel systems specialist Schueco Jansen, is proving popular with architects because of its enhanced specification, improved performance characteristics and ability to satisfy the aesthetic concerns of local authority planners and conservation officers.

Now being seen as the preferred solution for many refurbishment projects, especially those involving a listed building, elegantly ‘retro’ Janisol Arte 2.0 offers an enlarged range of profiles with slim sight-lines from 25 mm. A wider choice of glazing bead shapes – right-angled, bevelled, scotia and flat – makes it even easier to find an exact match for the steel windows being replaced.

Furthermore, since laser-welded profiles can now be added to standard Arte profiles, mullion spans can be significantly increased, so enabling the Janisol Arte 2.0 window to accommodate much larger areas of fenestration.

Available in all the opening types commonly encountered in both pre- and post-war industrial buildings, maximum vent weights have increased to 150 kg thanks to the introduction of state-of-the-art, 3D adjustable stainless steel hinges.

Another benefit is that simpler fabrication techniques reduce manufacturing time by up to 85%, meaning that six and a half Janisol Arte 2.0 vents can be produced in the time it took to make a single vent in the previous system.

Special new foam profiles located between the glass and the frame mean that the insulation in the Janisol Arte 2.0 window has been significantly enhanced and following the introduction of insert profiles – which also speed up fabrication times – results in drainage that is even more reliable.

In addition, because all Janisol Arte 2.0 profiles now go through the latest ZF 100 galvannealed hot-dip process, corrosion resistance has been improved and processing weldability enhanced.

Finally, as well as standard, premium-quality steel profiles, clients can opt for Janisol Arte 2.0 profiles in high-grade austenitic 1.4401 stainless steel or Corten steel, completing a specification that is thought to be unmatched by any other renovation window on the market.

Kingspan Insulation products have been installed throughout the envelope of the new in-patient unit at St David’s Hospice Care in Newport, creating a warm, comfortable environment for patients to receive first-class care.

The 15-bed unit adjoins an existing day hospice, providing specialist support for patients with complex symptom management needs, end of life care and occasional respite care. Each room features a wet room and a private terrace, providing views of the newly-planted wildflower meadow and hills beyond. The Welsh Government has provided £3 million towards the cost of the unit which has been constructed by Andrew Scott Ltd.

KKE Architects selected natural materials for the building cladding, including tumbled sandstone and cedar shingles, providing it with a welcoming external appearance. To ensure a slim external wall construction whilst also achieving the target U-value of 0.16 W/m2.K, Kingspan Kooltherm K8 Cavity Board was specified within the cavity wall sections of the construction.

The unit, which holds an Energy Performance Certificate of A, also features a highly insulated floor and roof, with both elements achieving a U-value of 0.10 W/m2.K. To deliver this, almost 3000 m2 of Kingspan Kooltherm K3 Floorboard was fitted along with Kingspan Kooltherm K7 Pitched Roof Board and Thermaroof TR27 LPC/FM.

Kyle Fowler, Architectural Technologist at KKE Architects commented “The Kingspan Insulation products delivered reliable performance, enabling us to achieve our desired design details. We were also able to contact their technical support team throughout the design process, ensuring the completed elements performed as expected”.

Since the completion of the in-patient unit, Kingspan has launched its Kooltherm K100 range offering thermal conductivities of just 0.018 W/m.K across all thicknesses. The expanding range now includes K103 Floorboard, K107 Pitched Roof Board and K108 Cavity Board, helping buildings to achieve outstanding levels of thermal performance with a minimum construction thickness.

The UK construction industry is worth nearly £100 billion to the UK economy each year. But tighter restrictions, increasing build costs and a lack of skilled labour are threatening the sector’s future growth.

But where there are challenges, opportunities can also be found, and the sector has seen several innovative solutions come to the fore in recent years. This is particularly true when it comes to prefabrication and offsite construction products.

These “pod” solutions are being deployed across a wide range of new and refurbishment build projects, from hotels and leisure to education and research facilities. And with the backing of the Government, their usage is only set to increase further.

But why are offsite solutions becoming more popular, and why is the Government keen to back them? In short, they deliver quality at scale, and help projects of all sizes complete on time and to budget. Currently the demand being placed on the construction industry continues to rise, but the number of projects completing on time and to budget continues to fall. This is not just due to tighter regulations and labour shortages, but other factors like the weather and delays in the supply of materials.

Factor in housing shortages, an aging population, an increase in speciality housing needs, a lack of suitable student accommodation and an uptick in the number of build to let homes, and it’s clear to see why prefabricated solutions are being more widely used.

Modern pod solutions are therefore becoming more popular as they can be designed, manufactured and pre-assembled off site, and then simply dropped into place for ease and speed in new build projects but still provide the high quality expected. Specialist manufacturers design and build tailored pods, to perfectly meet client specifications and these are simply delivered whole ready for installation and fitments or re-assembled onsite quickly and easily for refurbishment. Installation does not require skilled labour, significantly reducing time and costs.

When it comes to bathrooms and showers; these can be the most complex part of a build and require wet trades and a range of skilled labour, from designers to plumbers, electricians and tilers. Pre-fab pod solutions however, can be completely bespoke and designed to fit into any space – whether a Grade II listed manor house, an office block, a refurbishment or a new-build.

Sectional pods are ideal for limited spaces, and bespoke designs can be completed from concept to delivery much quicker than manual builds, where a whole host of factors can slow down the build, from the late delivery of materials to several contractors having to work together, in confined spaces and reliant on other trades’ staged completions.

Health and safety is another concern for contractors, and moving construction off site into a factory environment significantly decreases the risk of an accident. Purpose built construction lines have been designed specifically for pod manufacture, and are the safest environment.

There are other benefits, too. When pods are manufactured offsite, the on-site assembling process is far quicker and quieter with less people needed, thereby reducing labour costs. Not only is this cleaner and safer, but it keeps disruption to a minimum – there are less materials and vehicles on site, making the site more efficient and easy to manage.

Pod solutions also deliver on quality and efficiency. A traditional building site can be a source of wasted materials because of finishing, fixing and snagging errors. Prefabricated pods eliminate this; bespoke and resourceful design keeps wastage to a minimum, and their longevity (most come with a min 25-year guarantee) means they are a green alternative to traditional build materials.

Often pod materials can be recyclable, reducing the carbon footprint of the build and providing a sustainable, quality assured building solution, for the future. The best quality pods are designed so that they do not even require sealant, yet are still 100% water tight and the materials used greatly reduce bacteria growth and therefore maintenance costs.

The Government have also recognised the benefits of offsite construction. It has said it will support ‘building long term collaborations’ with the industry, ‘exploiting digital technologies such as the adoption of offsite construction techniques’.

In addition, it said it would ‘adopt a presumption in favour of offsite construction by 2019 across suitable capital programmes’. This stands as further evidence of the rising popularity of offsite modular construction.

As more and more projects are completed, construction management will recognise that modular design can be commercially viable alternative to traditional builds.

Sleek designs and high specifications mean they can be used from high-end projects such as hotels, right down to student accommodation, and still deliver a solid ROI.

In fact, the high specification, unrivalled quality, offsite checks and lower maintenance can extend the longevity of the bathroom environment way beyond those offered by traditional builds which often require on-going maintenance.

Hostile environments are no longer such an issue, either. From city centre apartments to rugged surroundings, installations are no longer a logistical nightmare. From oil rigs to research centres in Antarctica, there is nowhere bathroom pods can’t be installed.

Offsite construction currently accounts for less than 10% of total construction output. But this means there is tremendous scope for further expansion in the building sector. The Government is on board, a growing number of construction managers are on board – what are you waiting for?
