Thanks.  That's a pretty cool system, and is essentially what I was shooting for.  Though I'm guessing it would cost many thousands to buy, and then I've have to do a major retrofit job.  That pump is going to draw as much as an amp I'm guessing too.  Do you mean like a heater core?  That...

It's difficult to tell how efficient the stock furnace is for LP use.  I never saw in the manual that it said what it was.  It might be decent though, you're right.  I'm pretty sure it has an aluminum exchanger, and that fan does flow a lot of air over it.  It's likely a great solution if you're...

You're right, in that case it's probably not out of place.  Totally different case though.  I've determined that TV has no place in my life in general though.  Scourge of our society imho.

The TV probably has its place in some cases. I wish I could do solar. Not enough sun and too many trees.

That's probably spot on.  It's just really striking to me that there isn't an electrically efficient heating system even available.  That 80 percentile is probably more like 99.  I suppose I can't blame the rv industry for the downfalls of our society. I put shelves in my rv where they intended...

I won't discount that the heater buddy's are great. And I don't doubt that they are fairly safe. It's hard to tell if it's the heater causing the condensation, or if it's the dripping wet clothes I'm trying to try. Probably both. The main problem I have with it is it doesn't let me use my...

That is likely.  It would be difficult come up with a system that draws as much current as those furnaces.  Water holds a lot more energy than air so you're going to need to move a lot less of it, which is an energy savings.

It really bothers me that in general, rv's are designed with the assumption that you'll be plugged into 110.  What are they thinking?

The in floor is the way to go, especially in homes.  Looks like a lot of work though, and the pump would add electricity into the equation again.

Others have mentioned that as well.  On my trailer, which is only a 19' mind you, all the fresh water plumbing is above the subfloor inside the cabinets.  It's not a problem for me, and I intent to cut vents in the cabinetry to allow warm air to go where it needs to.  I'm not too familiar with...

You would need a pump in a system like this for two reasons:  1)  the distance you're piping the water creates too much resistance.  But even then, it's going to flow. People tend to underestimate how powerfully hot water rises and cold water sinks.  2)  More importantly if there are dips and...

I thought hard about using the existing water heater.  I think it could be done that way, but i don't like the idea of having to drain the radiator during the winter.  It doesn't allow adding antifreeze to the heating system.  I hope it works great, because I think the dometic furnace is a total...

My RV, like many, has a central air propane furnace. These furnaces have two problems that make them pretty much garbage for boondocking: 1) the heat exchanger it uses to transfer heat from the combusting propane to the cabin air is extremely inefficient. I think that has mostly to do with it...
