Options for in cabin heaters
Forget about electric heat. Your batts won''t do it.
If your going to have your boat for a few years more, I think you would be very happy with the Force 10 Cozy Cabin heater.
As WOOOSH(Jack)Described, the heat is dry and the bad stuff goes up the pipe.
This unit can be bought complete for about $300.00 then you have to buy the tank regulater and gas lines and install isn''t hard. Do you already have propane on board?
