Space Heating from Engine Coolant

[Alan Wheeler]

I am using the Force 10 Propane heater. Works well and we have a really big area to heat, somewhere near 2000sqft. The only7 problem I had was where it was fitted. I kept backing into it when I entered a storage locker and it melted a hole in a jacket I was wearing. So I made a really lovely Alloy grill with Brass trim around it which is cold to touch, yet the heat still comes out just fine. They are safe. Don't be scared of gas. If you have it onboard for water heating and cooking, then fitting a heater is dead easy. They have all the sensors for flame failure safety.
Those diesel heaters are so DC power hungry and noisy, plus so darn expensive.

The Espar only uses 1.1 amps at 12v. I thought that was very reasonable. That is at it's medium setting, there are a couple of heat settings above that. What I like about them is that I can put the unit in the engine room and not worry about ducting the exhaust out of the cabin roof.
