The heat will be ducted to the various "rooms" in the bus using PVC pipe. The ducts will also spill heated air into the insulated water bays to help keep the tanks from freezing. We have a small Dynaglo LP heater (one made to use inside) hanging on the wall in the bathroom area. We will add an LP heater in the fireplace mantle in the front salon as well.
I am trying to picture this and I just can't!! Do you have any link to images or schematics that explain it? I am visual so I find it really hard when just reading it like that....
Only pics I have posted are here




The rear heat exchanger was bolted to the bottom of one of the seats (the only seat we kept because we didn't have time to remove the heat system). I don't seem to have any pics up (somewhere I have them) but we cut the hoses, drained the coolant into a bucket, looped the hose back onto it self to make the circuit complete again, then removed the heat exchanger and the attached fans from the bottom of the seat, cut the hole in the floor for the "return" air (the now cooled down warm air gets pulled thru a regular home furnace air filter and pushed back the the radiator fins of the heat exchanger by the attached fans) and discovered that the heat exchanger setup would hang nicely between the center beams that run the length of the bus (how nice was that!). David hung it, drilled new holes and bolted it into place. It's still hanging under the bus (only 150 miles later). Our goal is to get it hooked up once the weather starts cooling off. We've got the old water heater in place (did that before we left), I bought the hot fluid pump online and tested it. Bought & installed the electric heating element, rebuilt the ignitor for the LP. All we need to do now is run pvc pipe for ductwork, install floor ducts, run the PEX (bought) and buy all the little golden fitting$$$$ to make the fluid circuit. It is simply a very basic hydronic heating system. I had bounced the idea around in my head but didn't broach it to David until I found an article where someone had did the same thing. They used a small car radiator (heat exchanger), fan, el Cid pump and RV water heater to build a small set up. By reusing the rear heat exchanger, that gave us the fans already on the unit and we had acquired a very old RV water heater when we bought some other RV stuff from an old RV being parted out. All I had to buy was a hot fluid circulating pump (could not use one of the potable water pumps we already had due to the high temps being pumped). The article had disappeared from the internet again. It was called "A Simple RV Hydronic Heating System by Jim Phypers (Fri, 29 Jul 2011 11:26:34 | Water Electrolyzers http://www.panorooma.com/water-electrol ... ystem.html *1991 Jim Phypers) I have it copied down as a PDF on my computer. I hqave learned to do that after losing so much info because I believed the "once it's on the internet, it 's there forever". Unless it's something I need to find. Like the Poop Sheets which have returned on a couple other sites.

Here is a link to the text and here is the main image you would need



Clear as mud! I guess that would make it "Transparent".

If you don't want the expense of an RV water heater, you can also use a small 6 gallon point of use electric water heater. It depends on how you use your bus in cold weather and if you have a non electric back up heat for time when the power goes out (we do).

Re: A hippie with a not-so-minivan

The eberspacher heaters are used to pre-heat the engine for easier starting in cold weather and instant heat in the morning. There should be a controller up at the dash. You can get installation guides and other documentation at http://www.eberspacher.com. They're nice heaters and might qualify as the "heater separate from the engine heater" that Quebec requires. Bloody governments are out of control these days.

Here is the controller that came with our bus:

Re: A hippie with a not-so-minivan

I read your post about the ride home. Now that you made it, you know it isn't a big deal! You survived and learned. What a trip, eh?

Re: A hippie with a not-so-minivan

Thanks Lorna, that link really helped! I do think it sounds great but it is a bit too complicated I think for us and I think that we would rather go with wood heat when we are stationary and find another solution for when we are on the road if we can.

Roach, OK... I get it now. but I don't see anything else that is remotely like what you have or what is on their site.. I think that if I can get the bus on the road I might get that checked out. It sounds like a good system if we could make it work.

100MPG... yep, a trip indeed. And you are right... driving it isn't that big a deal. backing it up into a tight space is stil a bit nerve wracking though

I was thinking this morning...

I have seen a few people use the mini-splits in their skoolies or RV... if I were to take our stock AC out, I think that could be a good solution if we wanted AC... and we could use the already made vented compartment on the side of the bus We still have not decided yet but I the more I think about it, the more I would like to be able to use the space that the AC takes up and have a smaller unit.

Re: A hippie with a not-so-minivan

I have the mechanical inspection tonight! Which means of course that I will have to back the bus back into our driveway when it is dark... oh my....

I have a feeling that think might just work out to get the plates but I am still not 100%.... I got a transit today so I can head to the inspection and then once I have the certificate in hand I might just be able to go get the plates as long as they don't ask too many questions. I think more questions would be asked if we were changing is from a bus to motorhome but since it is already a motorhome... well... maybe they just won't ask!

Besides that... I found a soft spot on the floor in the back. I am hoping it is just the plywood underneath (I am hoping that there IS plywood underneath)... It is in the back where the storage place was so I could just visualize army guys with feet full of snow etc standing there making the floor super wet and stacking duffle bags (or weapons) since I found a letter about transporting weapons in the compartment over the driver.

Re: A hippie with a not-so-minivan

Good luck, I hope it all works out.

I dropped my bus off for the inspection tonight as well. I was told it may take a couple days as they are busy and will get to it when they can.

Re: A hippie with a not-so-minivan

Don't pop the cork yet!

The inspection was at 6:45pm and after being there for two hours... it is done! The only problems were three lights (one bulb, one was not grounding and one socket that need to be changed) And the other problem that he didn't mention on the inspection was the wiper fluid because none of us could find it!... Ummm, anyone know where to put wiper fluid in a 92 All American Puller??

It was great, I asked the guy if I could follow him around so I learned a few more things about the bus. One thing that I am glad to have learned is how to adjust the slack adjusters and he confirmed that the air brakes are self adjusting but showed me how to check them.

So! With the Inspection papers in hand I am going to try to get my plates tomorrow...

Roger that!! My local DMV took 5 (count 'em, 5) tries to get my title right. In the end I had to bump the problem up to the Secretary of State herself. It erased any microscopic vestige of faith I had in government.

Congratulations on passing inspection!
