We are building a log home in N. Arizona. It is located off Grid. Our county requires we have thermastatic controlled heat in every room. Because we have a small solar system, we are considering slant/fin hot water baseboard heating. How do you install a thermastat in this system? Can you turn off a zone so that it only distributes heat in the zone you want? Is there a better system for us, on a small budget?

We have two soap stone fireplaces for the majority of our heat, but the county does not recognize them.

We are thinking of using a tankless instead of a boiler to keep the cost down, any suggestions or opinions? Thanks!!!
