How well does your dash heat and defrost work on your diesel pusher. Each year we make one trip in winter and have the same issue the dash heat puts out very little to no heat and does not keep the windshield defrosted very well.

I have shut off valves on the heater hoses and they are turned on. The fan puts out a lot of air but no heat and the windshield fogs bad. Using the coach heat makes it even worse for defrosting due to the propane heat condensation.

How well does your dash heat and defrost work? Diesel pusher only please.

Mine works pretty good. Probably need to have it checked out.

Ours blows hot air but it takes a couple of minutes for hot air to come out after turning the dial to heat. No doubt that is because the hot coolant has to travel almost 40 feet.
Our coach also has 6 inch fans in the top corner of each side of the windshield. In cold weather it helps a lot in circulating the warm air across the windshield.

Modern propane furnaces don't exhaust humidity back into the coach.

Ours works very well. Takes a couple of minutes after a change to the temperature dial for the hot water to circulate the length of the coach and heat the mass of the front coils, and then she’s pumping heat. Maybe 2x the amount of a typical car I’m guessing. Which is needed for all the wide open space and glass.

Ours works great. We also have overhead fans that blow directly on the windshield.


There are 24 hours in every day - it all depends on how you choose to use them.

Cab over truckers use a vinal cover that snaps on the front covering the radiator to hold the heat in the radiator.

1.You appear to have a 15 year old unit.
2.Dash Heat will be in the 145 to 165 range on a Diesel
3.It is not uncommon on a unit as old as yours to have a clogged Water valve restricting the volume of hot water
4. You need an actual temp measurement of the hot air coming out to determine if you have a problem. Doug

Also need to compare temp of hoses at both ends. Might be loosing heat because the hose runs thru cool area, or because of limited water flow.

If you are getting condensation from your propane durnace, GET IT SERVICED ASAP! This is not normal, and indicated a cracked burner compartment.

As for better dash heat... there are many supplemental diesel-coolant heaters on the market, and can supply heat when parked if you add the electric water pump option.
