In fact I'd have thought the whole Webasto system would be quite good to have in a vehicle living in a place with very cold winters. If it were me I'd be fixing/replacing the heater unit.
We would have loved to keep the Wabasto heater, however there are too many bad parts. Someone in the past had pulled the front wire harness when the circuit board inside the controller/timer fried. The fuse holder inside the rear power transfer box also melted. The water pump on the main unit is seized and the burner chamber needs refitting of the fiber washer. (these are the bad parts we know of)
There are some parts available to rebuild these DBW46 Wabasto units but the prices are sky high!

There are also newer units available, and in the future we might fit one of those. We do plan to keep all the parts from the heater so if anything is needed then we can reuse. For now the idea is to remove unnecessary bits to streamline the coolant system and reduce clutter.
