oops more-- Furnace trouble

OOps more

I forgot ,, sometimes the furnace pulls away from the side of the coach and
the exhaust is blown into the inside of the coach.
This could be fixed by taking out the furnace and resetting it.

The failure inside the furnace is a baffle plate rusts out or off and the
combustion products go into the heated air. This cannot be fixed, it is an
internal failure.

Both situations are very dangerous

This happened to us, and we only noticed from outside the coach when we saw
the panel around the vents was actually melting/burning. That was the last
straw for us, as we scrapped the propane system entirely for a webasto, hot
water heater. It is totally quiet, and puts out a lot more heat than the
propane set up ever did. The heat also lasts, and does not dissipate as
quickly as forced hot air did. It was a lot of work, but worth it.

Tony:

Did you install an air or water system?? Either way, how is the heating
distributed throughout the coach?? What model Webasto heater did you use??
Does it use propane??

We installed a diesel fired hot water system, the model is a Thermo S90. I
totally scrapped the propane system, as I have an AC/DC fridge, so without
the heater, all I ran off propane was the stove. (That too was replaced with
electric, but that is another story) We removed the propane tank, and put
the heater in there. A diesel tank, 10 gal, was put under the coach in the
rear, with the filler in the old propane locker. This thing will run for a
long time on 10 gallons.

The hot water is circulated thru radiator hose to 2 heat exchangers made by
a company called red dot. they are very low amperage fans integrated into
the exchangers. I get almost instant heat, and plenty of it, and it stays
hot for hours.

Another bonus is that I no longer have to adhere to propane restrictions and
can go through tunnels. This is a plus here in the NY area.

In the future, I am hoping to install a loop to the hot water heater/ engine
loop so I can pre-heat the engine and make hot water.

Like I said, it was a lot of work to install, but it is a great system. Let
me know if you have any more questions.
