Haven't got a clue

Did a 30 by 40 garage with infloor heating. Please tell me how you would pipe this and what controls you would use. I know your going to ask for all kinds of parameters, so I will do my best to provide as many as possible. There are 6 loops all @ 220 feet in lenght. Heat loss was calculated at aprox. 26,000 BTU. Design floor temp. was 85F with a space temp. of 72F. Pump was spec'd by wholesaler. Please, if you could give me a layout of piping and controls that would be used. Might be using a water heater for source of heat. I know a water heater isn't the best source for any hydronic heating application.Garage will be maintained at just above the freezing point most of the time and occasionally bumped up to a more comfortable working temp (68F).So would all I need to use is a mixing valve to maintain floor temperature at 85f, and a space stat. to bring on the circulator on a call for heat? Sounds easy, but I don't have a clue and any help would be good help. I only want to do this once. Thanks

Design, materials etc.

Honesty helps but it won't make your system either functional or efficient. Many here are willing to do e-mail interviews and offer a variety of solutions to your design questions, few will give you off hand materials lists. Select a supplier and have them coach you in their style as dictated by your expectations, application and budget. Enjoy....Dan

In the first place you cant expect your garage radiant system to act like a regular zone. You're heating up this mass of concrete and you plan on keeping the space just above freezing but occasionally you want to bump up the temp to make it comfortable to work in there. Now you have to raise all this mass many degrees just to warm the space above it. If you want to work in the garage on a saturday I suggest you crank up the t stat the monday before. You're better off just coming up with a satisfactory "all around temperature" for your garage set the thermostat and maintain this level 24/7
