I am going to use a Proheat X45 unit for my heating and hot water. I was wondering what type of heating units are you using and do you have it broken into zones with a single water pump or do you have a circulating pump for each zone. My water heater will be one zone and I am looking at the REAL fan heaters sold by www.suremarine.com (http://www.suremarine.com). Thank You.
Steve,
We made a very simple system, that is one loop. From the ProHeat unit, in the center bay, the water goes to a Flat plate heat exchanger that has the other half connected to the engine (a separate circulating pump on the engine side) in the front bay. From there it goes to a large heat exchanger with a fan installed in the end of the sofa behind the drivers seat, then to a toe kick (with fan) in the kitchen and then to another toe kick (with fan) in the bathroom. From the bathroom it goes to a small heat exchanger (with fan) in the rear baggage compartment where the water/waste tanks are. From here it goes to an expansion tank in the middle bay and back to the Proheat.
Note: We are for the most part, "warm weather campers" rarely experiencing temperatures any colder than the upper 30s, YMMV Jack
Hi Steve,
Jack has a good set up.. It looks like you are on the right track with the Real units from Sure..
It now depends on how you will be using your coach to ultimately choose the right set up for you.
If you will be boondocking most of the time then I will reccomend that you go with baseboard rads
and eliminate electric consumming fans. If not much boondocking, then unit fan heaters are the way
to go. You can either zone them out with costly controls or, do it simple and use t-stats to only bring
the fans on when calling for heat. If the proheat and piping system stay hot all the time, there will
be no cold air blowing out when the stat calls the fans to start up. I think this is the best way to
set the system up because most of us also preheat our domestic hot water with the same source.
Have a Great Christmas

How many air handlers do you need in a bus. I was thinking of purchasing a Proheat m80 and using it for hot water and heat for the cabin. I was thinking one handler in the living area up front, one in the bunk/bath area in middle, and a smaller one in the back bedroom. Would that be enough to heat the bus that is well insulated with spray foam?
Also, is using diesel heater efficient in a bus that will see very little boondocking? Thanks

IMO. If you are not a boondocker, nothing beats all electric.
So would you not recomend a proheat diesel heater?

My coach is all electric. So no, I wouldn't.
I have run my generator 24/7 + on a run down the Alcan to Minneapolis. My heat and AC are 220v.
On the pole in an ice storm in NE Arkansas...trees down power outage for days. people around me were running out of propane.
All electric isn't for everyone.
That said I have enough house battery to sustain "no gen" hours in National parks etc.
I could get by with only generator electrical heat to warm the bus, but I have a Webasto and it warms the walls and the floor while electrical is kinda limited to the space it is running at. The Webasto heat is cozy, like a wood stove in a house.

Mine is central ducted fan forced warms everything.
and virtually silent white noise at best.
I had the proheat x45 on the M C I that ran the infloor heat front to back with 3 zones + 1 forced air fan rad under the fridge ( 32 k btu ) on a separate loop
when on the road it was free heat from the 6v92ta off a heat exchanger
to the rest of the system
nice system but lots of work
