No boiler heating in eco-friendly houses |

Two low-energy houses were built in Douglas.
They were built based on a decision by the Climate Change Citizen Forum and members viewed the land on Friday.
In view of a possible boiler ban in a few years, these semi-detached houses on Victoria Road will be heated with electric heating instead of conventional gas or oil central heating.
John Sheppard, director at Wren Sustainable Limited, and Steve Crowther, architect at cre8-iom, worked together on the project.
John took pride in the achievement and said the houses were the first of their kind in the British Isles.
He said, ‘I’ve been working on it for 20 years.’
John continued: “When we met Steve, we combined our interests in architecture and sustainability and it worked.
“We have an eco property with that aspect of sustainability and affordability.”
A house is heated by a 1.5 kilowatt heater for the winter and the bills are about 40 pounds for a quarter.
The finished unit without heat supply except solar gain averages 18 degrees.
John said, “You’re going to get very, very low bills.
“Heating is out of order, also electrically, but incredibly efficient due to the high level of insulation.
“The big problem is usually heat loss, but that gives you very little.”
The heart of the new property is the ventilation heat recovery.
Each room removes all of the heat and puts all of the heat exchange back into it.
The only heat that gets into the house comes from solar gains as well as the waste heat generated by your body.
John said, ‘It actually doesn’t cost anything.’
Average heating and lighting bills are estimated at £ 100 a quarter when fully occupied, with the only additions coming from the kitchen cooking and the bathroom with shower.
On the outside of the houses there is a permeable pavement that serves as a tree root protection system.
That is, when the rainwater comes down it is directed into the top of the parking lot, then it is filtered down and sucked into the ground.
No drainage system is required to remove it, everything is treated on site and trees can still be planted.
Steve emphasized the sustainability perspective.
He said: “It is important to me that it is integrated into the landscape.
“This is just as important to me as achieving zero CO2.”
The architect explained the controversy in the UK and how we can learn from it.
He added: “In the UK we have to deal with green belt incorporation. What we want to do is look at how we can integrate affordable housing into better landscaped spaces. ‘
