LARS FABRICUS describes how central energy plant can be used with local hot water generators in dwellings for maximum efficiency
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.
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.
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.
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.
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.
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.

UHMA (the Underfloor Heating Manufacturers’ Association) has launched the UK’s first independent training course in the design and installation of underfloor heating.
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.
Heating for a luxury penthouse created during the conversion of a church into 12 apartments is provided by an Even-Heat underfloor heating system.
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.
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.
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.
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.
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.
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.
Air-conditioning specialist Mitsubishi Electric has created a new consultants sales team to offer a specialist service to architectural and building-services consultants.
Consulting-engineering practices are enjoying buoyant business, according to the latest state-of-business report from the Association for Consultancy & Engineering.
LG’s air-conditioning division has reported a major upswing in orders for its ranges of VRF and mini-VRF systems. Orders have been received for a wide variety of sites — including commercial offices, health centres, sports facilities and retail malls.
An initiative by two major contracting organisations to help its members meet health-and-safety competencies has been welcomed by the Health & Safety Executive. The move by the Heating & Ventilating Contractors’ Association and the Electrical Contractors’ Association comes against a background of increasing prosecutions by the HSE as too many building projects and developments use contractors that flout relevant legislation, standards and good working practice.
Over 12% of construction work by value is no longer subject to the practice of retention, according to the latest assessment by the Specialist Engineering Contractors (SEC) Group. The latest additions to the group’s list of clients that no longer include retention clauses in their construction contracts includes the following.
Not only has the 100 days of Carbon Clean Up campaign organised by the Chartered Institution of Building Services Engineers made a useful contribution to reducing the UK's emissions of carbon dioxide, but it has also shown how much can be achieved for just a little investment and how important it is for everyone in an organisation to be involved. An energy manager alone cannot achieve very much. With the support and involvement of everyone in an organisation, from the board downwards, success is assured — as the experiences of award winners in the campaign demonstrate (click the link below, "The 100 days stories').
Legrand has upgraded its e-catalogue. It includes all the company’s products — over 50 000. It is supplied on CD and can be updated via the Internet.
