Using OTR heater blower and exchanger for normal heating.

How does the solar work for heating you see a lot of it now on Rv's and boats both for water heating and cabin heat

Thanks Dan I believe when you drive in the cold or live in the cold you better be prepared.
Things freeze up fast when something quits.
As long as one of the diesels start I got it all covered.

Now you've got me pondering...

I just found a system like you're talking about. https://www.solartechdirect.com/collections/water-heating-kits/products/heliatos-solar-rv-or-boat-freeze-protected-solar-water-heating-kit

Quite interesting, especially since our water heater has an unused heat exchanger built into it that could be used with this system. Might be the answer to our question of how to heat water when we're not plugged in. If we decide to take the plunge on this next spring I'll report back.

I have 3 x water panels like this ( but are pressurized )  for domestic hot water at my house and it is installed pre the regular water heater and with full sun the regular water heater never turns on

and 4x of the same panels that heat my bus barn when the sun shines

only problem with this on a coach is it takes up a lot of space

That's the thing-- some people don't want ANYTHING on their roofs because it detracts from the original bus look, while others go for roof air, vents, satellite dish, and solar panels.

I have been thinking about using the OTR Heat core to cool the engine as well.  If you don't mind can you tell me how you diverted the heat in the summer to the outside?  I have been trying to figure out how to do that.  What kind of diversion vent did you use?  Do you have any pics?

On my Fishbowl with the 6V92 I have the DBW 2010 Webasto plumped into the engine cooling system. the water leaves the engine and goes to the Webasto, then goes thru a heat exchanger on the side of my 110  electric water heater. From there the water goes to a manifold, if I wanted to heat engine only I would open one valve on the side of the manifold. The water leaves the manifold and heads to the Onan 7.5 diesel then returns back to the engine. The manifold also has a loop to a heater in the bathroom that utilizes a old rad core from the front heater with a pancake fan to power the air flow. The original front defroster and heater and the under the floor heater are still in the place and used as intended.

The interesting result is when i am running the generator ( summer or Winter ) the generator will heat the 6V92 to approx 140 degrees when camped.
I have turned on the  under floor heater fans with the diversion vents to expell the hot air to under the bus to add extra cooling of the 6V92 in he summer heat. The diversion vents are closed in the winter.

I leave all valves open most of the time so all loops are hot and ready helps with cooling in the summer with the bigger cooling capacity.
Going down the road with everything flowing the water in the electric water heater is almost too hot and i have a tempering valve to install to prevent scalding water from the potable water side.

Sorry i missed your original post DT rattled my cage and i responded but lost it.
When the air goes thru the OTR heater it goes towards the back and branches off to each side, then turns up towards the inside of the bus.
I cut a door and put two hinges and a slide lock when i don't want heat going into the coach i open the door and it blasts out to the ground.
The passenger side i just installed a vent that blows onto the top of the tank. (cheap tank heater)

It works good with the door open and the coach heat fans on high. I can see the temp gauge moving downward. Lots of extra radiator to dissipate heat.

I'm having a hard time figuring out what I am looking at in this pic.  I see the door but I can't figure out where it is in the bus.  Could you help me out?  THanks

Follow the heat ducts at some point they will turn upward to enter the coach.
The picture is on my transit fishbowl so i'm looking from the ground up.
If you have bays the duct work is likely in one of the bays.
All i did was allow an exit for the hot air prior to going into the coach.
Hope that is clearer than mud.

In my MCI it's reverse, 2 ducts coming up and the rest are all returns via the center tunnel.
