Q:  What if I need hot water for only one location in my cabin, like my kitchen sink?

Q:  What kind of fuels can I use to run my tankless water heater? 

Q:  I looked at tankless water heaters at my local hardware store, and there was a big difference in prices between models and manufacturers. Why?

Q:  So how do I know how big of a unit I need for my cabin?
