新建住宅的最佳供暖系统是什么?

What you are suggesting is exactly the way we do it – start a home on a slab on grade with in-floor radiant heat.我会给你们列出一份阅读清单，涵盖了你们所要求的大部分内容，我们可以从那里开始。

First, we would only ever choose electric heat, fossil fuel heating is on its way out. read more here –Why Electric Heating Systems are Best for Zero Energy Homes

As for the slab on grade with frost wall – an alternative to explore is araft slab frost protected shallow foundation with air heated radiant floors这是我们最近在LEED白金示范住宅中建造的。它们可以用煤气或电加热;我们当然选择了电。一种选择是使用空气-水热泵在水进入锅炉之前进行预热。

As for the concept of heating with electricity - Cape Breton seems to have variable power rates, and the raft slab mentioned above provides so much thermal mass that with an energy efficient home you would easily be able to set a timer so it only heats during off peak hours, which can make it quite affordable.

As for not having cold feet, good call. Cold feet leads to people jacking up the thermostat to compensate, whereas if you had warm feet you can keep the air temperature in your home a bit cooler because the surfaces you are in contact with give heat to your body rather than steal it. Read more about that here, in our page abouthow to design a home for thermal comfort.When you heat a floor you will obviously have happy feet, but you increase the differential in temperature between your concrete floor and the ground below, so don’t skimp on insulation!

For a climate like Cape Breton, you would be wise to have 6 to 8 inches of insulation below your slab. Not much more, but not much less either for comfort and cost efficiency.
