Electric Heaters in 5er

Hey people,

I have been using a fan heater to keep myself warm so far this year. The temps will drop into the 20s at night before long, and Iím hoping to get another electric heater to better keep up. Has anyone found a type of electric heater that works best (ie micathermic, ceramic, infrared, or an efficient fan heater)?

*I never run these when out of the camper, and I have a dedicated space with no fire hazards around.

How are you keeping RV plumbing lines/tank warm?

Space heaters are great for area YOU are in but not much good for keeping plumbing from freezing

1500W space heater draws 12 Amps
More than 1 on same circuit will trip the 15A CB for the outlets

When we had our 5-r, we never had to heat the nose since heat rose. We preferred the oil-filled radiator-style heaters. Sure they're slow to warm up, but once heated, they stay hot long after they've been shut off. Plus they were silent, no fan noise to compete with the TV.

x2 on what OB mentioned. How are you keeping the water lines from freezing?

I've found the Infra Red Wood Frame to be the best. They move more air at lower fan speeds and keep the whole space warm rather than objects.

This is an example
Infra Red Wood Frame Space Heater

I haven't used used this specific one, but one like it. We used two in our 38' motorhome while our house was being built. Temps got down to -20F and we stayed comfortable and water lines unfrozen with them and the propane furnace.

Thank you all for the swift replies.

I didn’t realize that the furnace would make a difference in the belly. Im currently in a good set up where there’s an easily accessible bathhouse nearby, so I was going to winterize and just do all things water there.

So it seems as though the fan heater I have now could suffice if I also need to run the furnace.

As in many things RV, it depends. While the 5th wheeler has a heated basement from the furnace our smaller MH does not have any plumbing under the floor except the waste water tanks which are heated along with the drain pipes and valves.

If we're in boondocking mode then we use a propane Buddy heater when we are awake and in the RV. After bedtime it is only the propane furnace in either rig. We also carry an infrared electric heater for when we are on shore power.

We've been out with morning lows hitting 4F and 8" of snow and highs in the 20s. Never a real problem. I've learned in the MH if we are expecting lows below 25F I'll dump the tanks and add about 1/2 gallon of antifreeze to both empty tanks to fill the drain areas.

I know our 5th is good down to 0F and the MH's lower temp is unknown.

If you are going to run more than one electric heater determine which outlets are on different circuit breakers and make sure to use multiple circuits. In some RVs there may be at least 120 volt circuits, one on each side of the RV. But RVs are wired in so many different ways, who knows without checking it out yourself.

I like the radiator style electric heaters at home, but think they too large and heavy for our RV use. What type is best? Depends on how you use your RV. One will warm the entire space slowly, others will warm you and other objects quickly and thus in turn warm the space over a period of time.
