Practical solar energy

Solar energy technologies for buildings are no longer limited to add-on technologies. They can now be integrated with the fabric of buildings — with significant cost implications. CLARE HAWTIN tells the story.

Terry Wyatt
The time has arrived for ground-source heat pumps — Professor Terry Wyatt.

Renewable heat – the era of ground-source heat pumps

With carbon-dioxide emissions being 50 to 60% lower than even a gas-fired condensing boiler, ground-source heat pumps have a key role to play in a low-carbon future. PROFESSOR TERRY WYATT explains why he believes their time has arrived.

Helping design better underfloor heating systems – Brian Sensecall on new standards.

Underfloor heating – better comfort by design

A new standard for calculating the performance of underfloor heating systems is not only simple but very accurate. BRIAN SENSECALL explains how it works.

Church heating
Today’s gas-fired fan-assisted convectors can make very short work indeed of heating churches. Bill Sinclair of Rinnai suggests that the warm-up time would normally not exceed an hour and a hal, with the heating cost for a service generally being under £5 — including pre-heat period.

Redefining the performance of gas-fired convector heaters

Forget the heating of village and church halls of your youth. Gas-fired convector heaters have advanced enornmously — as BILL SINCLAIR explains.

What’s best for your business?

Heating remains one of the biggest operational overheads for industries throughout the UK. The Government’s Climate Change Levy has added an extra cost to all fuel bills. Switching to energy-efficient space heating technology will minimise fuel consumption, benefit the environment and, most importantly, reduce costs. DAVID ROCK of Ambi-Rad Limited explains.

Electric underfloor heating requires little depth and can be used with a wide range of floor finishes — including wood, tile, laminate and heat-resistant carpet.

New opportunities for electric underfloor heating

Technological advances in recent years enable electric underfloor heating systems to provide optimum comfort and be economically viable, says SIMON BRODERICK.

Underfloor heating/cooling can be combined with underfloor services using Osma’s RAF system.
