I've been shopping online for gas appliances and am stumped by the small refrigerators and high costs. Does anyone here use propane refirgerators? What are you using and how satisifed are you with the cost and efficiency? I've considered getting a refrigerator and a separate freezer but don't know how gas-wise that would be. I have to get a btu estimate for my gas line. Also who is using a tankless water heater. Do they require electric as well as gas? I'll have a modest solar set up and don't want to pull my watts if I can get by with the old style tank gas heaters but these tankless systems are on everyone's lips right now. Thanks in advance.
