Floor-vented gas heater

[paddywagon]

Does anyone know of a floor-vented propane heater? I recently purchased a ProTemp water heater that exhausts through the floor and is a really clean install. Was wondering if there is a similar setup out there for a space heater? I'm trying to minimize the holes I'm putting in the walls and roof.

Not propane but all of the air diesel heaters do the same thing. Webasto, espar and the Chinese clones.

Propex, HS221 is a good one.

Best to mount it outside and vent the heated air into the interior though.

Just looked it up and it's exactly what I'm looking for. Thanks!

Why do propane heat at all? The moisture those things generate will trash a bus interior in short order if you don't ventilate properly.

The new diesel air heaters are so easy and reliable it blows my mind why people still waste time and money on those propane furnaces.

Over a pint of moisture for every lb of propane burned.

[john61ct]

The Propex unit produces ZERO moisture inside.

All the burn output is vented to the outdoors.

Only fresh air from outside is heated.

Just like the diesel and gasoline fueled parking heaters.

But then you're dealing with constantly having to top off propane tanks to stay warm.

With a diesel heater plumbed into the bus tank it's as easy as keeping the tank full.

Less work the better I say.

Most rvs have decent propane storage and it’s likely a lot cheaper to run propane than diesel I would guess. I kinda agree with the single fuel idea but propane stoves are fairly ubiquitous too. Either way, makes sense for some and not for others.

Get a bigger propane tank. I think I wil have no issues with a 29.3g tank.

The most satisfying times I’ve had with my bus have been when I was cutting holes in it

Don't get one like mine then, many of the parts are stainless steel and cutting or drilling it is a royal PITA.

It's exactly the opposite for me. Things I hate about our bus are:

1. the insurance nightmare
2. thick, hard, oversized, inaccessible material and fasteners. Removing/cutting/drilling anything is such a suffering. Why two quarter inch thick, 3" wide stainless steel brackets to hold up a single seat? Why?

I have good reason for going propane. My bus runs on petrol, not diesel, so I don't have diesel on board to begin with. My stove and water heater are propane, so that made the most sense.


My water heater and soon-to-be furnace are both externally vented which means they use outside air for combustion and exhaust outside. This prevents oxygen depletion and moisture buildup (as well as toxic emissions) inside the bus.



I have a strong opinion against putting holes in my bus, or at least the walls and roof. Any opening creates the potential for a leak and I love the clean, uninterrupted lines of my bus.

Look into a "cheap chinese" plasma torch. There are a couple of youtube videos out with $200 plasma torches that work great. I bought a better brand from a local welding shop but LOVE mine.

another advantage to propane is odor outside.. if you are in a campground where there's lots of other people, diesel heaters do emit diesel fumes when running.. propane exhaust is much less odor for those around..


I love my diesel heaters and for what I use my bus for its the perfect solution. . propane hjeaters with ehat exchangers leave zero moisture inside.. if you get good ones that are condensing then you end up with 95% or so efficiency as well.

[john61ct]

Yes that Propex unit is both very fuel efficient on the LPG, and not too thirsty electrically.

Mounting outside helps make it quiet within the living space

Good point. Maybe I keep my little catalytic heater installed for times like that

I did both the diesel air heater and a propane Catyletic. Offers flexible heat options. I also kept the original bus hot water heaters for underway
