oil radiator heater

Please turn off caps lock. It is considered yelling here.
To answer your question, maybe! Where are your water lines, your water pump? Better to blow the lines out and add anti freeze to the "P"traps no matter what else you are considering.

Yep turn off the caps. What city/area are you keeping RV for winter?

For the small cost of the RV antifreeze it seems cheaper than running and electric heater all winter.

Perhaps if you're only talking a few nights per season...maybe.

Did you c o insider just blowing out the water lines?
The heater will work, depending on your location.

the heater will not keep pipes,etc. below the floor from freezing.

Hi,

If you replace the return air grill for the furnace with a dual window fan and place the oil heater right in front of that it may keep the water lines from freezing.

Personally I would blow the lines and winterize.

WHY?

I could see it as a usable strategy if he lives in an area where freezes aren't intense. Where he uses RV all year long. Also does depend on where the plumbing is-such as mine with the plumbing and fresh tank in the walls or interior of RV.

So I think it is a good question-but there's a difference between a location like Kernville CA and Fargo ND-and he still hasn't chimed in with that.

We use our MH year around so we do not winterize. I prefer to use a couple of small ceramic heaters set to low that move more air around to also help with mold and mildew. I place one on a 12x12 ceramic tile in the rear of the MH, and another one placed on the open oven door. I also set the MH's propane furnace to low that will circulate air within the MH and the "wet" compartments if the temperature gets below 35F, or the electrical power fails. I also have a heating pad with a thermal 35F switch that comes on in the compartment with water hook-ups and the exterior shower.

EDIT: I don't really want to be thinking about this now!

I kept one of the bigger oil heaters in a 24' TT in Oregon for 2 winters without winterizing. I mostly did it to keep out the moisture but it also kept lines from freezing. If its on all the time some of that heat will transfer through the floor and walls. I located the heater near the bathroom and kept it set with lower voltage switch on and the dial set on 2 most of the time and when it got down below 30 I turned it up to the max setting. All that said I have no idea if this will work for your setup. The one thing I do know is keeping a little heat in there sure keeps them smelling nice and new for years.
