Well the benefit to having the liquid radiant heat, is the fact that it covers your entire floor. Remember, there are several different kinds as well. The one I am talking about is overall the best.

If you have it installed while the house is being built, the lines are run on the ground throughout the rebar, next the concrete is poured over it and then the heating system is hooked up where everything keeps warm. You get an even heat throughout, and as you know, heat rises. If anything a heat pump may be what you need to regulate the heat to the rest of the house, or you can have it installed in the upper floors as well.

The other method some people may be thinging about are more like an electric blanket. Much more expensive to heat with.

Again, from my experience in the construction industry, I'd only recommend doing it while you build a house. Having it installed in a preexisting home could create a lot of headaches.

I was thinking of building it into a basement suite (for the in-laws).


If you are building the house then it won't be a problem. If you are buying it will cost you a whole lot of extra money as you will have to dig up your basement floor.

Not necessarily, depending how high the ceilings are it may be possible to just place the piping on a thin layer thermal insulation(to prevent heat being lost in to ground through conduction) directly over the existing floor covered a thin layer of concrete to finish the floor.

Radiant heat is pretty much the norm when you have poured concrete floors (where I'm from anyway) - I think it's funny that Koreans think it is uniue to them. You know the Romans used under-floor heating systems that were similar or more advanced than traditional ondol - Niro had a monstrous "pleasure barge" that had it.

I'm thinking this

or this

https://secure.thermosoft.com/radiant-floor-heating-products/shop/thermofloor-120v/

might be my best bet if buying a previously built house.

So you are talking about 1000 dollars to do one 12 ft by 12ft room.

An entire basement, for a bungalow, say 1000 sq feet, would run about seven grand. Plus GST of course. That would be well and good if you could save money in the long run, but it is still just one big electric heating pad from the way I see it.

Sounds like a lot of money to keep the inlaws comfortable. Give em a pair of slippers, some longjohns, a blanket, tell them what a couch is for and save some money!
