Theoretically, it seems more logical to me to spend money on energy efficient and gas powered appliances now rather than have astronomical electric bills down the line once we are settled in. Every appliance we have purchased has either been an energy efficient appliance or an appliance powered by propane.

I really wanted to have tank less propane hot water heater but don’t know too much about them. I have been doing research and reading customer reviews of On Demand Hot Water Heaters and think I found the one we are going to purchase. If any of you know anything about Propane On Demand Tankless Heaters….please speak now before we make this big purchase!
