对于普通基础上的小板，水(乙二醇)和电辐射热哪个更好?

On a small footprint foundation (26 x 19 feet) what is better and/or more economical for radiant heat? I am hesitating between water with a micro boiler or electric (wires).
Also, do you think in a chalet this size with a mezzanine (70% of 1st floor) that I will need additional heating in the mezzanine bedrooms and small bathroom?
Thanks!
Mark.
The best radiant floor heat for any particular location depends on a few factors, namely thetype of power在你的地区和成本。If you are fed by affordablerenewable energyin your area like some States and Canadian provinces (like Quebec for example) the best choice would be electric, whether than is electric wires or a liquid (hydronic) system with an electric boiler. See more here about whyHeating with electricity is the cleanest heat source.
But, when electricity rates are very expensive and when the grid is fed with a dirtier fuel, hydronic with a gas boiler is often the better choice. So first I think you should decide on your fuel source, being electric or gas. Then get a few quotes from local installers.
Another option would beair heated radiant floors, which is provided by a company calledLegalett that distributes engineered slab on grade raft kits all across North America.
至于夹层的加热，这取决于几个方面——它是否隔热和密封良好?吊扇的形式会使空气流通良好吗?Andwhat climate zone are you building in?
谢谢你的回应，迈克。
The cottage will be close to Morin-Height, Quebec - so climate zone 6 I believe
I will look at the Legalett option. It would be interesting to learn the benefits of air heated vs. glycol or electric wires.
关于夹层供暖——小屋将采用相当传统的2x6英寸的墙体。我想知道是否可以在夹层的地板上增加通风口，让热量更容易上升，但我也有点担心声音会穿过地板。我们计划在阁楼前面高高的天花板上安装一个吊扇。
Cheers!
Hey Mark, For Quebec the answer is always pretty easy actually - go electric. And with that I don't mean just the electric wires, I mean no matter how you heat it - wires, hydronic or air, the cleanest and cheapest energy is electric. If the mezzanine is closed in (which I'm getting the impression it is if you are concerned about sound through vents) I'd just stick a baseboard heater up there and be done with it. They are super cheap to buy and there is no difference in operational cost from radiant floors to an electric baseboard radiator. It may or may not go on, but for the cost it's the simplest solution.
