Heater?

[bhh]

Anyone used one of these for a heater when hooked to shore power? It would seem to be quiet, compact, and at 425 watts, plug friendly.

So, no one has ever tried or had one?

The mechanical motion creates heat, so it all ends up as heat. Now if the heater created light and some of the light found its way outside the camper, that would make it less than 100% efficient in heating the camper.:h

I didn't look at the specs but 425 watts is not much heat.
I use a little 1500 Watt electric heater that has a tip safety switch and it does a fine job.
I think we paid $19 for it about ten years ago

I use a 1200w radiator style electric from Costco.
More heat, less money, still just 10 amps max so no plug burnout.

ALL electric heaters are perfectly 100% efficient.
Only thing more efficient is a heat pump where you would get twice the heat from the same electric.

That should put out less heat than running your toaster or you could light a couple candles..425 watts equals about 1475 BTUs. Your RV furnace will put out 35,000 BTUs. So if you bought and used 23 of these you would have about the same amount of heat output as your furnace..

First: TOO EXPENSIVE though the "Footprint" may make it very attractive.

Many 1500 watt heaters make fantastic claims about effiency and how well they heat but the fact is they all put out EXACTLY the same amount of heat, EXACTLY, all are EXACTLY 100% efficient, can not be anything else in fact.

And in many cases the standard wiring on an RV is not really up to a sustained 12 amp load.. I often smelled "hot wire sent" when we used the standard RV outlet... Since I installed special heater outlets (15/20 amp, this one has a "T" shaped neutral slot) with 12 ga wire, properly BENT AROUND A SCREW and tightened, and one outlet to a circuit breaker for the feed.. No odd aromas.

Very happy.

$139.95 heater at 425 watts = 1,450 BTU at $.10 per BTU purchase cost

$20 generic electric heater at 1,500 watts = 5,118 BTU at $.004 per BTU purchase cost

Both will cost the same per BTU to operate since both are virtually 100% efficient.

Major issue is the panel heater costs seven times as much and puts out less than 1/3 the heat.

We have a 750 / 1,500 watt ceramic box heater that's mounted under the cabinets above the dinette. Space is at a premium in a 24' m/h too. We use it move the air around in the summer too.

It's so quiet I can't hear it running unless I really concentrate.

[mowermech]

$140 for a 425 watt heater, when I can get 750/1500 watt units for less than $50?
And, it does not have a fan?
Thanks, but no thanks!

We use a freestanding electric fireplace that is 1500 watts and it will heat our 36' Class A quite nicely without using the propane heaters.
It is better at maintaining temperature rather than raising it from a cold start.

19' travel trailer, non-hybrid, no slide outs.

I have a few smaller heaters, ceramic box, parabolic reflector, and forced air. Concerns are
* something falling on it during the night and either overheating or shutting down
* fan noise
* current draw (1500 watts will draw 1500/120 = 12.5 amps, a pretty big draw on a 20A pole if there's anything else running (water heater, fridge, lights, battery charger, etc.)

Yes, I understand the "efficiency" as there's no such thing as a free lunch (first law of thermodynamics).

Dont pay attention to the energy efficient/low energy use statements. When you heat with electric you retain all of the energy you are paying for. Its only called low energy use because its putting out a low amount of energy.

425 watts is not much heat. High efficiency doesn't mean much, all electric heaters are 100% efficient, no energy is wasted.

We were GIVEN one of those AMISH type heaters (brown box with quartz heater inside that doesn't get warm on the outside). We use that in our 5'er and it keeps it really warm without the dreaded condensation that you get with lots of other heaters.
