It's that time of year to think of heat.

I have 2005 Fleetwood Excursion 39S DP, Cat C7, Allison, and two furnaces.

While traveling during the winter months the heater (running off of the engine hot water) up front heats that area nicely. In the rear, while it gets a little heat from the engine under the bed, it is cool to cold back there. I have run the rear furnace, but that of course uses propane.

Under the bed there is lots of room to install an auxillary heater that would run off of the hot water lines running from the engine to the front heater which run right under the bed anyways. I assume I'd install a heater with a 12V two speed fan. There's a 12V fuse panel under the bed so power is no problem. I would cut a hole in the bed pedistle, mount the heater under the bed so that the heater grill is even with the outside of the bed pedistle. If the heater grill doesn't look nice enough I can easily put a better cover over it.

Does anyone see any reason not to do this or have better suggestion?

    Check out these heaters from AQUA HOT. They have the 100 model and the 200 model.



    Since you are into HYDRONIC type heat already you may want to look into using your on-board hot water heater as source for hot water to heat with.

    Consider this idea perhaps...




    Perhaps a vented CAT WAVE TYPE PROPANE HEATER install


    I still love the good ole fresh made bean coffee taste the first thing in the mornings getting out from under the nice heavy blankets sleeping in the cool weather.

  • I would think that idling the Caterpillar would get old, fast, just for heat. Look at the thread Espar and hydronic heating. Since you have diesel onboard, the Espar is a great fit.

    If you just want to distribute engine heat while traveling, a heat exchanger is all you need. There will be some work to install the two hoses.
  • Looking on the internets, they make ducted versions of them too. Pretty nifty.

  • Go for it. You might get everything you need at a junk yard. Many full size vans have a rear heater just like you are considering.
  • There is no reason not to if you feel the need. They make them compete with integrated fan. If your water heater has the fittings you can plumb it in also and the engine will heat that too.
