Just wanted to share this, since I was unable to find any information similar when doing this project.
Me and my family use the MH a lot during the cold winter here in Norway. It can get colder than 30 celcius below freezing, (-22 F), but normally around -10 celcius (14 F) during winter. The Hymer Exsis-I (integrated motorhome) is well insulated, and has insulated tanks and a powerful Truma gas / electric heater (6000 watts).
The problem with this solution is that you either
a) must rely on using only electric, which yields only 2 kilowatts of heating - which can be a bit on the low side - and requires a connection to a 230v / 10 amp minimum outlet, or
b) changing the 11 kilo gas bottles almost every 24 hours, if it's quite cold etc.
Also the Hymer has a few cupboards, but nowhere really to dry clothes. This is a big issue when the family returns from a day in the slopes or from a cross country ski trip, and needs to dry off a lot of clothes.
The solution to this I thought would be to retrofit a diesel heater, if at all possible, considering things like available space, heating of the water tanks etc.
So I did a lot of examination of the Hymer's underside and inside.
The following had to be tackled in this project:
0) Which heater product to buy, and what capacity.
1) Where to put the heater.
2) The direction of the heater.
3) Where to place the outside ducting if mounted outside
4) Where to put the heated air flow silencer (really a clever thing, but optional)
5) Where to let the ducting enter the MH from outside
6) Where to put the ducting inside
7) Where to put the vents
8) Would it be possible to get heating inside the cupbords?
9) Would it be possible to get heating into the bathroom?
10) Would it be possible to get heating from the diesel heater also into the water tanks to avoid freezing etc?
11) How to make sure to get a bit of heating in most parts of the MH
12) How to allow for efficient (and recommended) ducting to maximize heater operation.
13) If mounted outside, how to insulate the ducting using what kind of products.
I will try to describe the different sections and how I reasoned for my choices in the following posts. You can also view the short video about the installation. Have fun laughing at my Norwegian-English
