Retrofit a diesel-fired heating system?

[Pete Masterson]

In the 'history' section at Vintage Birds, they show the info for
each year. 1994 shows "Primus heat" and 1995 shows "AquaHot".
However, it's my understanding that some 'birds may have had a
Webasto system around the mid-90s.

The AquaHot was in all models, BMC, 40' and 42' models, (the 40' had
the DD 8v92, the 42' the DD Series 60 engine). The 1994 listing shows
Primus for the 40' and doesn't name the furnace brand in the BMC
version.

Yes, the 2010 has more power... 45K BTU. However, from what I understand, this
is not
variable. Its fuel consumption is constant at about 1.5 liter/hour.

Because we plan to do a fair amount of boondocking, I chose to go with the
Thermo 90.
Its variable output makes it highly efficient with fuel and power consumption.
It is
significantly smaller also.

Here are the specs for the Thremo 90

Variable Heat Rating: Boost 31,000 Btu/h (9.1 kW)
Variable 6,100 - 26,000 Btu/h (1.8 - 7.6 kW)

Fuel Type: Diesel #1, #2, Arctic
Fuel Consumption: Boost 0.29 gal/h (1.1 l/h)
Variable 0.06 - 0.24 (0.24 - 0.91 l/h)
Rated Voltage: 12 Volts

Power Consumption @ 12 Volts: Boost 7.5 Amps @ 12V (90 W)
Variable 3.0 - 6.9 Amps @ 12V (37 - 83 W)
Water Flow: U4846 - 7 gal/min
Dimensions: 15-1/8" L x 5-1/4" W x 8-21/32" H
15-3/4" L x 7-1/2" W x 14" H - w/optional enclosure box
Weight: 10.6 lbs. (4.8 kg)
35 lbs. (16 kg) w/optional enclosure box

Here are the specs for the 2010

Webasto DBW 2010 Heater Specifications:
Heat Rating: 45,000 Btu/h (13.1 kW)
Power Consumption @ 12 Volts: 7.1 Amps @12V (85W) w/ coolant pump
Fuel Type: Diesel #1, #2, Arctic Water Flow: U4846 - 7 gal/min
Maximum Fuel Consumption: 0.4 gal/h (1.5 l/h) Dimensions:

23" L x 8-1/16" W x 10" H
24" L x 9-3/4" W x 11-5/8" H w/ Enclosure Box

Rated Voltage: 12 Volts Weight: 33 lbs. (15 kg)
65 lbs. (29.5 kg) w/ Enclosure Box

The 2010 is a beefier unit and will probably outlive the T- 90, but there are
trade offs.
Like everything else, It depends on what your needs are.

That is if it runs constantly. With the proper wiring interfaced with
the thermostat it is appreciably less

I would be interested to know more about your installation. More than half of our outings are dry camping all year around. Where did you mount it and where did you "tap" into the chassis heat. Does it warm your block also?

Chuck,

Its mounted in the rear basement compartment on the driver's side at the back
end of
the compartment. Its just in front of the aux pump on our FC. Tapping the
coolant loop
just in front of the aux pump was pretty easy. There is plenty of room between
the
bumper and the compartment.

Yes it does heat the block very nicely within an hour or so.

I located the heater in the rear for two reasons. My priority with this was to
heat hot
water and the coach first the engine block 2nd. If I need to heat the block
fast, I can
always run the electric block heater too.

1, Because its in back, it is close to the domestic water tank and it reaches
there first. In
the winter position, it then circulates through the coach exchangers and then to
the
block and back.

2,The front compartment on the passenger side is close to the batteries and this
is where
I installed the ProSine inverter/changer. Eventually, I want to put additional
batteries at
the mid compartment on the drivers side where the Iota DLS chargers remain as
back-
ups. The wiring is in place and If I install AGM in there it should be pretty
simple and I
don't have to be too concerned with venting them. If you want more info or
photos, you
can e-mail me at bgaramella@...

[Bill Garamella]

Yes, you are right. No doubt, the 2010 would bring the whole business up to
temp
faster then the Thremo 90 and cycle off sooner. Then on and off as needed to
maintain.
The net consumption over time would certainly be much less than constant
running.
