In Floor heating

[russp]

I built a 1400 sq ft house with attached garage, for the main heat I installed a forced air furnace but I also ran in floor heat in the basement & garage. I used a standard 33 gal gas hot water heater & it works fantastic. It is a closed system and I run a max pressure of 10lbs hot. If you hire a plumber to install it they will tell you that it is not allowed but if you do it yourself it is a great way to go. I could easily maintain a 20dg temp all winter & the square footage of the heated area was about 1000 ft in the house & 500 in the garage. The main items you will need are a water heater , circ pump & expansion tank. but as previously mentioned the first step is to pressure test the pipe layout.
