New green high-technology can now give householders hot water for only around £1 a week and central heating for about £5 a week, says Stourbridge energy expert Colin Priest.

He says the latest British designed thermodynamic panel system has already proved popular in the UK and is selling worldwide.

“It is the green energy’s equivalent of the next Dyson vacuum cleaner and could revolutionise the industry,” said Colin, who lives in Quarry Bank and works for Noreus in Stafford.

The aluminium system, which can be fitted on a wall or a roof, provides hot water at 55 degrees centigrade 24 hours a day, 365 days a year, even if it is cloudy, raining, windy, frosty or snowing outside.

Colin, pictured, said the system works like a fridge in reverse. The panel system absorbs heat from the atmosphere, and the refrigerant fluid is transformed into a gas. It moves to the thermodynamic unit which compresses it into hot gas before going through a heat exchanger to warm the water in the nearby cylinder. The gas then passes through a valve in the unit where it reverts back into a fluid and returns to the outside panel to begin the whole operation again.

He said the environmentally friendly system takes only about a day to install the system - preferably on a south facing wall or roof - plus the thermodynamic unit which can fit in a standard immersion cupboard or loft. The big advantage to the home owner is that they don’t need to buy a new cylinder if the existing one can be utilised. However, a new and improved cylinder designed for the system can be supplied and installed if needed, or requested. Also there is a five-year ‘no quibble’ guarantee, minimum maintenance and the system should not overheat or get frozen.

“But the main advantage is that it will reduce your hot water energy bills by up to 90 per cent,” said Colin. “Hot water costs will come down from around £400 a year to between £40 and £60 while central heating bills will be cut from about £800-£1,000 to between £240 and £300 a year.”

He added: “Although there is an initial outlay for the system it should pay for itself within ten years - or less, if energy prices continue to rise significantly.”

However, he reminded residents that to make the system work efficiently they needed to retain the heat in the house and not let it escape through the roof.

Colin suggested spray foaming the loft with the Icynene Insulation System, an environmentally friendly and non toxic investment which reduces heating bills by up to 50 per cent. “If you don’t have insulation all you are doing is wasting energy and letting the birds enjoy the heat you are producing, as they know the warmest places to perch on your roof,” he concluded.
