[QUOTE="Mr. Mach-ete, post: 13980623, member: 16424"] The issue with radiant heated driveways is the amount of heat energy required to keep them above freezing. Incredible amounts of fuel are consumed keeping the driveway even to 40 degrees (f). I engineered a radiant garage and partial driveway for a very wealthy man. I laid over 3,000 feet of oxygen barrier 1/2" pex tubing of which each run could not be greater than 250 ft due to friction loss. The supply and return header system was elaborate as Hell. The were very expensive bronze cast thermostatic sensors that were poured into the concrete which monitored the pad tempurature. You need to be extremely careful not to circulate to hot of water as it will crack and damage the concrete. Therefor the water must be tempurature regulated coming from the heat source. Which is most likely going to be an on demand system couple with a storage buffer tank. Need some pics and more info regarding the dimensions of the area you are looking to heat. [/QUOTE]
