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.
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.
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.

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.
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.
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.
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.

Surge in VRF orders for LG

08 November, 2006
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.
site
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.

Clients abandon retentions

08 November, 2006
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').

HFL cooling towers have an intelligent controls package to switch between these modes to match requirement and minimise water consumption by operating in adiabatic or dry mode as much as possible. Capacities of up to 2 MW are available from a single unit, with water consumption being reduced by 40% compared with conventional cooling towers.
trunking
Marshall-Tufflex has launched a cable-management system with a distinctive curved profile. Odyssey is said to be the first 3-compartment uPVC system on the market with a completely curved outer profile.
Design software for VRF air-conditioning systems from Mitsubishi Heavy Industries is available from 3D Air Sales. This is said to be the first software to enable 2-pipe systems to be converted to 3-pipe — and vice-versa. The software is available free from 3D and HRP.
colt

Research in Japan shows that this filtration technology gives exceptional anti-virus, deodorising and anti-oxidant characteristics.
Autron has introduced an anti-microbial finish to its range of low-surface-temperature (LST) radiators.
The first wireless building-management system launched by TAC Satchwell is said to offer an 80% reduction in installation costs. Simply by eliminating the need to install cables between every control point, Andover’s Continuum can save miles of wiring on major installations.
