Yeah we have a 500 gallon LP tank and use that for (on demand) hot water, backup generator and cooking, but our primary source of heat is in floor electric radiant (floors are concrete slab). We also use a mini split system to compliment the in floor heat and to provide cooling in the summer. And of course we have a wood stove as well. Unfortunately we are in a narrow valley and don't get enough sun to make solar a viable option.
