My wife and I have purchased 20 acres in rural Island Co. We will start building in one year. We will not have access to natural gas. I plan to install radiant heating and would like to use propane (also for cooking and hot water). Are there boilers that can use propane?
The home will be less than 2,000 square feet. Will I need a large fuel tank?
Most natural gas models are available in propane versions. For radiant heating, high efficiency units work very well as they love the low water temps.
If you insulate well and install good windows, a 500 gallon tank should be plenty.
This site has tons of good info.
