I'm building a house in Minnesota. I'm thinking about putting hydronic heating in my basement and garage. I have a contractor that is willing to do both, but I have a couple of questions about the garage. How long would it take to warm up? I know this probably depends on a number of factors, such as garage size, insulation, and outside temp. It will be a 3 car, with 2x6 insulated walls and ceiling, and say the outside temp is 20F. Would it take 1 day, or 1 week, or ???
My second question is, should I ask the contractor to put the tubing closer together? I'm not sure if there's a standard spacing, but maybe I should have him double it? Would that help, or am I limited by the output of my heater?
Any advice would be appreciated.
