Over the road heating...

[Busted Knuckle]

The temperature gauge would not get above about 120 degrees unless I put the throw rug in front of the radiator. Then it would climb up to 180 degrees and stay there until the outside temperature would start rising. Then the gauge would start climbing up toward 190 degrees and that was I knew when to remove the rug. I had plenty of heat as long as I covered the radiator. Took me awhile to learn to do that, so I supplemented the engine heat with the Webasto.

OK see now the rest of the storey unfolds! Our coaches aren't hot rodded stripped conversions. (Yes I did have the "Hot Rod Setra" but it came that way from the factory and I never has excessive overheating problems, that releasing pressure off my heavy right foot couldn't cure!)! And again I agree with Tekebird if it had proper working shutters, the throw rug wouldn't be neccessary! But given the fact that you had to do all the mods to prevent overheating in normal weather, it explains why there wasn't sufficient heat in the cold!   BK

I do not recall ever seeing an Eagle with shutters.

  I still have all the plumbing for OTR heating but the motor and fans are gone and the coach interior simply covered over all the ducting.   I like the idea of radiant heating. Seems more comfortable than forced air.

I guess I will have to experiment to see how many heaters will work.    I like the idea of a heat exchanger for the furnace.   

Here in the Northwest,  coach heat is probably used more than A/C.
      Thanks,   Iver.

I don't fully understand the heating system yet but found that turning the switch to heat and pulling the manual valve on by the driver that there is more than enough heat. I'm with BK and Gumpy on this one. Jerry

This is an obvious indication that your thermostats were not working properly. With temps at only 120*, the tstats should be closed,
and should not allow enough flow through them to the radiators to keep the engine cool. If you were having to cover your radiators
just to get the engine temp up, then the tstats were not closed. Possibly installed incorrectly, or one was stuck open, or not shutting
all the way.

What you say makes sense, but apparently enough cold air was getting around/thru the throw rug to keep the engine cold. After the outside temperature warmed up to about 40 or so and I removed the rug, the temperature then rose to the 180 degree mark and stayed there as it should have. With the throw rug in place the temperature would rise to the 160 degree level.
