Re: Help with understanding heat - as in furnace & water
I can further confuse you!
We have a propane tank and a Propex propane furnace (not sure SMB offers this brand). We like it because it is quieter and uses less electric power than a Suburban type propane heater.
The Espar products run on diesel, most people only get them if they have a diesel engine.
A flat plate is a type of heat exchanger, usually used to transfer heat from the engine coolant to a hot water system. This system can produce hot water while the engine is running, and for a little while after shutting it down.
Any hot water system is subject to freeze-up in cold weather. People do various things to prevent freeze-up, like draining the system, blowing it out with compressed air, or adding food grade antifreeze.
I don't think there is an off-the-shelf option for cabin heating with engine heat, since the engine would need to be running.
