I have a Ceramic heater I have been useing to conserve propane. Lasko brand I got at walmart. Seems like a pretty good unit.

These things draw alot of power though. I was useing it at a RV campground where power was free hook up with space rental.

I used it at home and my electric bill was about double what it usually is.

I also noticed it realy makes my generator work hard.

Well that little ceramic heater keeps it warm in side all night and works great except the power bill.

Anyone have any more effecient heater ideas, or equipment that they have found?

Most ceramic heaters have two heat settings: usually 1000 and 1500 watts. They are great for heating small spaces like a camper or a small room. As far as its effect on a generator, if you're using one of the 1 or 2 kw generators, the heater is taking up most of the capacity. A larger 3kw and up shouldn't have a problem unless you use other high usage appliances at the same time.

As far as a house is concerned, heating large spaces is better left to central systems or other large space heaters.

I found that ceramic heaters eat a lot of power because of the way they throttle to a constant load and never really shut down. I use the ceramic when on the road (free power) but find that the oil filled electric radiator is a bit easier on the wallet when at home. Yes it uses 1500 watts to heat the oil but the oil once heated continues radiating heat after the element turns off and does not cycle as often.

Due to safety concerns I do not travel with the oil filled radiator. During a panic stop I would not want to think of how fast it would be rolling by the time it got to the front of the motor home.

Put very simply, amps=watts/volts.

Amps=1500/120=12.5 amps.

12.5 amps over an extended period of time can add up to a fair amount of money.

Whether you use a ceramic or an oil-filled heater will make no difference in energy used. It takes a certain amount of energy to hold temperateur in an area. The oil-filled will act as a heat sink and continue to radiate some heat even if the oil heater element is off. The immediate area around the oil-filled will be a bit more even in temperature.

The only real way to get more efficient heating for the $ is to use more insullation . We use a couple of small space heaters to keep from using so much propane. On really cold nights I will set the furnace to come on just enough to keep the tank area warm enough to prevent freezing.

Ken,

I used the 1500 watts is 1500 watts explanation but my wife maintained that with the radient heat from the oil filled unit and the way it would continue to radiate after the element shut down and slowly cooled off that maybe we could use the 900 or 600 watt setting and a lower temp and still be comfortable. I gave in and well she was right and saved us quite a bit on the electric bill.

A catalytic heater will be more efficient. However do your homework as they do burn oxygen and create deadly carbon mono oxide. Most of the newer units come with low oxygen sensors. I wouldn't go to sleep with one running and I would even then probably back them up with a couple of carbon mono oxide detectors strategically placed.

If you are dry camping, the only heat that makes sense is a propane ceramic heater, like a Mr. Heater.

I have both the fan/ceramic heater and the oil filled radiator. I prefer using the oil type as it does not make any noise ( read LIGHT sleeper ) and the heat sink thing makes for a more constant temp. I do think the fan type disperses the heat more quickly, at least at first turn on.

If you only want to heat a small space, you may save $ by using an electric heater vs heating a larger area with your furnace. For example, I set my home thermostat to 67 deg. and "top" off the heating by running a ceramic heater in my office to bring it up a couple degrees, then off it goes when I leave the room.

As for the MH, I primarily use the Hydro-Hot.....an extremely even heating source and great for the coldest of temps. But if the campground offers "free" juice, I'll run a couple of space heaters and let the HH supplement them as needed for comfort.
