Heating airtight buildings

11 November, 2006
The air-leakage requirements of the latest Building Regulations will have an effect on space heating systems. KEITH SPRAGUE explains how radiant and warm-air systems will fare under the new regulations.
buses
A warm-air heating system from Reznor positioned to create a cyclonic rotating air-distribution effect is maintaining comfortable temperatures in Ensign Buses’ large depot and maintenance facility.
SAV
LARS FABRICUS describes how central energy plant can be used with local hot water generators in dwellings for maximum efficiency
Keston
Keston Boilers has supplied two SEDBUK A rated high-efficiency C55 boilers for the new £34 million Nugent House annexe of Eastbourne College. For speed of installation, the boilers were built into a bespoke floor-standing rig. Savings in installation costs were also made possible by the small-diameter flue system, which can run up to 45 m vertically or horizontally.
Skye
Stiebel Eltron has won a contract to supply heat pumps for 41 houses on the Isle of Skye. They will extract heat from the ground.
Eden
Comfort levels, space restrictions, interior design — the arguments for underfloor heating are endless. REX INGRAM gives advice on the planning and design of underfloor heating system.
school
Comfort and safety for children in a new primary have been achieved using a Robbens underfloor heating system. The new Church of England primary school at Yaxham in Norfolk replaces a building dating from the nineteenth century.
stokvis
The Econo-Air 3000 series of direct-fired gas heating and ventilating system from Stokvis Energy Systems incorporates high-efficiency burner and controls to optimise energy usage, minimise the effects of draughts and cold penetration, and instantly respond to falls in internal temperature.
orkney
Energy-efficient underfloor heating systems are being installed in the Piers Arts Centre in Stromness, Orkney, to provide background heating. The museum is being renovated and regenerated, with an extension to link the two existing buildings. The Raychem systems are being used extensively, including the entrance, galleries, lobbies and cloakroom areas.
apartment
Heating for a luxury penthouse created during the conversion of a church into 12 apartments is provided by an Even-Heat underfloor heating system.

Dimplex is a hot performer

08 November, 2006
The heating range of Dimplex includes products for most commercial, light-industrial and domestic applications — enabling the creation of fully integrated heating systems or the provision of localised room or spot heating.
Redring
The Redring Hotbox electric boiler provides economical heating where space is limited or gas is unavailable. These boilers drive sealed wet systems in light-commercial or domestic situations. They can deliver a flow temperature of 60°C to eight radiators against an outside temperature of 0°C.
boiler
14 engineering upgrades suggested by extensive customer feedback are incorporated into Ferroli’s new Optimax HE combi and system boilers. Almost all involve making life easier for the installer and service engineer by giving all parts and connections more hand and tool space — without increasing the size of the boiler.
chatsworth
Electric heating itself does not emit carbon dioxide, and nor need the generation of electricity from renewable and nuclear sources. DAVID RUMBLES reflects on a new future.
economiser
A reduction in heating costs of up to 30% is claimed by Airflow Developments by using its Economiser to take warm air from the roof void in large buildings and redirect it back down to floor level. This claim is substantiated by an independent investigation carried out by BSRIA. The product lends itself to use in retail warehouses, factories and community leisure facilities.
project
Nearly 2500 m2 of underfloor heating has been installed at Young Options College in Shifnal, Shropshire. Unusually, the tubing was installed by fixing it directly to the reinforcing mesh within the slab by Thermo-floor rather than installing onto the slab and then covering it with a screed.
UHMA (the Underfloor Heating Manufacturers’ Association) has launched the UK’s first independent training course in the design and installation of underfloor heating.
BSS
BSS has added a new range of tubular radiant heaters to its portfolio of BOSS-branded products.
Autron’s range of LST (low surface temperature) radiators has been independently tested by BSRIA for heating output and casing temperature — ensuring that specifiers, contractors and users can be confident of quoted performance data.
covrad
Coverad has developed a range of induced-airflow electric heaters for commercial applications that meet the needs of current legislation and cater for a market where safety, electrical efficiency, ease of installation, low maintenance and robust construction are required.
Osma
Osma Underfloor Heating has published a new guide for professional heating installers. It describes the wide range of solutions from the company and provides best-practice advice for working with underfloor heating systems in commercial and domestic applications.
buderus
PETE MILLS looks at some key considerations in designing commercial heating installations to maximise the potential of gas-fired condensing boilers.
cullen
NICK CULLEN stresses that value engineering should be solely focused on the interests of the client.
C100
CIBSE’s campaign to reduce carbon emissions this summer was an outstanding success. The outcome shows clearly just how much can be done for a small effort and investment. Our coverage of this campaign highlights the achievement of some of the award winners, with useful lessons for readers keen to mimic their success.
Peacock
A long-term energy strategy for the Peacock Group includes a simple approach to preventing electrical equipment being left on overnight unnecessarily.
Ludgate
United Business Media mounted a good carbon-saving campaign at Ludgate House in London, but it is clear that there is far to go.
Hughes
Even with five years of energy-saving initiatives under its belt, the Copthorne Hotel at Cardiff was able to embark on enough new measures to scoop the award for the most carbon saved.
clothes
Everyone in the Exeter office of a firm of architects is more aware of energy-conservation opportunities.
