For when you are hooked to shore power. Does anyone have any thoughts on using under floor radiant electric grids?

Might be a "shorter way around the barn"....

They even have one that is 12/110 volt switchable.

Is it human nature to take something simple and try to complicate it? Is it the winter doldrums?

One reason I mention this is I use a $18.00 box heater in my tear... the heater is on the top shelf, the warmth stratifies. I'm cool, but I put my hand up near the ceiling and it is 10 degrees warmer.... so, I add a fan to circulate the air.. now, all night, the heater goes off and on, the fan runs with a constant buzz...... finally I decided, I don't care. I'll let the heat sit up near the ceiling and the heater go off and on all night and I'll get rid of the buzzing fan.....

About radiant heat... I actually like the idea of it, but implementation might take a bit of doing, and I agree below the mattress makes little sense.... but, I think it migth be better in the walls than in the ceiling.... kind of fascinating, and it would be quiet. And, the wall are cold and I'm right next to them. Warm walls are good... I had even thought about adding a bit of carpet on them so when I touch them in the middle of the night it would feel better, but warm walls, now that would be great.

carpet on walls, etc

Tell me what I don't know.... Can you not put a heating blanket on your mattress, then a sheet on that then sleep on that? So you have the heated blanket under you ?

Carpet on the walls... I have toyed with that idea, for sound proofing, texture, and a little extra layer of insulation that would be easier on the touch... kinda like putting a rug on a wood floor.

An electric blanket doesn't draw much, and they have 12v versions (not sure about the draw on those).

One thing about cold weather camping is many c/g's close for the winter. I expect when I head to FL from New England in Jan/Feb, I'll have to do some checking to find a place open after the first day's driving.. once I get further south, I don't expect a problem.

First to Arnereil, of course we have to make it complicated first, that's how you pare it down to something simpler.
To Oklahomajewel, anyone can throw a electric blanket on, but what's the fun in that. It's a guy thing, we need to make it more technical than that.
To Toypusher, Now I think that the bunk warmer may be just the thing I was looking for, thanks.

Bwrbier and all,

Don't rule out a forced air furnace just yet...

It works well, heating my teardrop up in just a few minutes; it's vented, so you never have to worry about carbon monoxide poisioning; it gets it's fresh air from outside; and it runs on propane, so you can stay warm off the grid, or on.

Check out the thread here...

The eheat looks good, as I very rarely do not have power, even if outside a friends house while traveling... I like the quiet part... the heater is $80.00 and the thermostat is about $50... that's a kind of heavy hit for heat when a quartz heater is about $20.00 at h/d.... And the eheat will take the cold air and circulate it as it heats... a good concept. the box heate I use now has a level of hot air at the top, but the bottom, near the mattress remains noticeably cooler.

So, I do like the concept and will give it some thought....thank you for the link..

Yes, I use the same unit. Got it out of an old camper I bought for cheap. I did have to play around with the location of the thermostat so as not to alternately cook and freeze every half hour. The fan uses some power from the battery but a standard RV battery is enough for at least a couple very cold (below zero) nights.

I think the main difference is you bent your exhaust at 90* while I bent the ductwork 90*.

I don't have the photo of your heater installation... do you have a copy handy? A shot from the inside and a shot from the galley?

Arne,

If you can make it south of Richmond by the end of the first day, I think you'll be OK. There are lots of year-round CG's along 95 that stay open all-year for the Florida traffic.

We did it in 2 days, stopping in North Carolina.

I watched the E-Heat demo video. they say it should be turned on for 24 hours in advance of using it, and it is designed to stay on full time. Since it is only 400 watta, and is a passive heating system, that starts my brain turning over ideas to "do it myself and save $$". Why not use several light bulbs, or a heat lamp, in a aluminum enclosure that would allow air to pass through, but block the light from bothering you at night. This could be built for a few dolalrs, and be just as efficient, if not as space saving. Such a home-built unit could even be mounted outside, or in the galley of a tear, with air inlet and return from the cabin.

A small fan could be added to move more air. Small PC fans are quiet. I found a discarded CPU heat sink and fan when I took some scrap metal to be sold, and picked it up. I tried it at home, touching the wires to my truck battery, and it moves quite a bit of air with hardly a sound.

Sometimes I pretend to be normal. But, that gets boring...so I go back to being me.
