So an article on AT today featured DIY Radiant Heat floors. As we move forward on the house, this is becoming a reality that is fast approaching. Our plan is to have concrete floors with radiant heat plumbed into a solar hot water heater with propane back-up, because we all know I don't like to be cold!
Apparently the reviews on installing your own radiant floor are mixed with varying degrees of difficulty. I am a bit worried as if you make a mistake, its a BIG effort to fix it once the top finish layer of concrete is poured. Hmmm, that would stink. I am hoping that it might be easier in a house from scratch rather then retrofitting an existing floor, but this still doesn't sound like a walk in the park.
