Wave heater v electric heater

I agree with NC. We just spent a week in cold rainy weather in a site with no hook ups (our choice $30 vs $53/night) We had heat, light, refrigeration and cooking ability, all run on propane. The furnace does consume 10 amps of 12vdc power, but it only runs for a few minutes at a time. We only have two 100 amp/hr batteries, and I never had to switch to the 2nd one. A 15 watt solar panel acts like a trickle charger while we're away during the day. Even on cloudy days it works pretty well. Led lights draw almost nothing and provide nice white light.

That is a nice looking heater, but you can use a $15 portable one from Walmart and be nice and warm. Remember that when in a campground with electricity you can usually use as much as you want, so efficiency isn't a factor.

I used to be a tent camper, but as I get older comfort rules! I don't really think of our stays in the trailer as "camping".

That heater runs on 240v or 208v (huh? 208v?). Which I don't think you'll get in any normal U.S. RV park. But if you can find a 120v version, 2000 watts would require 16.7 amps AC. If you have a 30 or 50-amp service in your camper, OK, as long as you're on a hookup. But running it through an inverter off batteries for boondocking, it would suck 167 amps out of your batteries (2000w / 12v = 167a). Need a big battery bank for that... I'd go with gas.

Cow is the electricity expert on this forum. I believe that watts divided by volts = amps. In your case, 1302 watts divided by 120 volts = 10.85 amps.

11 amps AC if the tag is accurate. Could be more, could be less. Always better to measure. And remember, if you're going to run it off an inverter it's 10:1, so that's 110 DC amps out of the batteries.

If you get a big enough battery bank and inverter you can run the Large Hadron Collider off batteries.

I don't have any experience with Wave heaters, but I can tell you that in cold weather even just a single Humphrey propane lamp produces enough water vapor to cause significant condensation on interior surfaces like aluminum window frames and glass surfaces. This is in addition to the water vapor from 2 or 3 people breathing in a tiny space. Even with a window or two cracked, we have condensation. For these reasons, I think anyone contemplating camping in cold conditions should only consider a vented heater.

We have an Attwood Hydroflame furnace. Over the Thanksgiving weekend we kept the daytime temp in the camper at 65F, while the outside temp was in the 30's, then cranked it up before bedtime to 70 degrees for an hour or so. Piled on sleeping bags and blankets and shut the furnace off for the night, temps in the 20s. I kept checking the batteries thinking that all that running time would deplete them, but the draw was negligible.

The only downside I can relate to our furnace is that the fan is pretty noisy, cycling on and off many times in an hour. Not a problem while awake, but annoying when trying to sleep which is why we just shut it off at night.

In a campsite with electric hookup, we use a cheapo 120 VAC 1500 watt electric heater, same deal... run while awake, off at night.
