Webasto air to air unit

[Bob Gil]

I have been offered a chance to buy a Webasto for $100.00 but he does not know any thing about it.  Stated that he was not sure if it was working when he removed it in july (too hot then to test it) it was removed when they added a aux a/c and heat unit on a truck.

Are these repairble if it is not in good working order?

I know they are a lot more expensive than that on e-bay.

Any ideas would be nice.

Webasto has excellent online support. The detailed manual for the device will be available online, and everything pretty much is rebuildable and replaceable. German stereotype fulfilled again.

These are built for heavy use.

happy coaching!

what model?

Bob; my son has Webasto air heating on his trucks he has several of the model 2000 he removed because they didn't produce enough heat the 2000 is just 7000 BTU don't think that would work good for a bus  If I remember the correct number the for ones he has now are model 3500  have a great day

[tekebird]

my 3500 mounted midship in my 04 was good for shorts wearing down to about 30 Outside temp ( overnight)

they make a 5000 now

I can't imagin the 2000 not being able to keep a cab warm

Well; Tekebird the factory heater is 33,000 btu

Thanks for reminding me, makemine...

The Airtop heaters are often sized to keep an already warm truck sleeper warm enough to sleep in, not warm it up from cold. Their goal is to let the driver shut down the big diesel to save some fuel.

Many of them are certainly not big enough to raise the interior temp of a converted coach in winter temps. For more moderate temps, they definitely are an economical unit for taking the chill off a cool evening, as with the low output, they consume a miserly amount of fuel and electric.

For busnut design purposes, we still need to have a rough idea of how many BTU's will be needed to:

A) keep a warm coach warm

B) get a cold coach warm

For the outside temps we reasonably expect to encounter.

The economical way to approach this is with layers, a few smaller units brought online as needed versus a big one that can't be efficiently throttled back.

happy coaching!

The problem with trying to keep a Diesel tractor with sleeper warm or cool is that they have very little insulation in them.  If they have sheets of one inch foam-that's lucky.  This is why you need over 30,000btu of heating and A/C to keep the cab in decent temp range.  As compared to my 40ft that has 2.25" of sprayed insulation.  Two roof airs at 27,000btu total is enough to keep it cool in 107 degree weather while driving.  And two electic heaters at 11,200btu total is enough to keep it warm down to 25 degrees (coldest I've been in).  My 35,000btu propane furnace is a real kicker.  Good Luck, TomC

Here in God's country I don't think it will get real cold, and if it did i would only need it to help keep it from freezing the water in it. 

I don't know what model it is yet but i figure it should work in my suburban, or the bus to an extra heater but i will have to wait and see how it works out.

Thanks for the advise I know that some one here will know most of the time.  Or no body is going to know.

I have two 35000 btu heaters and an electric bay heater and trust me at 5 degrees above zero it's still pretty chilly in the morning and they go through propane like water at those temps. We ran a couple of electric heaters and supplemented them with my my furnaces. One great investment is a digital dual station thermometer. One reads the interior temp and one reads the temp in the water/sewage bay, it shows both temps so you can be sure you aren't going to burst a pipe. We did it for a couple weeks here in Nashville while they finished the house we are living in. It was mighty cold out.

I must say I would love a webasto unit, (filling those propane tanks every week sucks and it's expensive) when I was on the road as a touring musician we had webasto units in all the buses for all our heating and we played a gig in Fargo when it was 30 below! It was cold next to the windows but the whole band and crew were sleeping on the bus as we left the gig and drove through the night to our next gig. I don't know how how big the unit was but this a 45 foor Le Mirage and we were snugs as a bunch of musical bugs in a rug.

That's my two cents...
