I fitted an 8kw to my 109. I mounted the main heater under the body and attached to the chassis via a home made bracket, The heater sits at 90 degrees to the chassis just in front of the middle outrigger. The output hose enters the cab through the cover under the middle seat ( or where the middle seat would be if I had one fitted )
Given the vulnerable mounting position I made a custom aluminium cover to protect the heater , pump and fresh air combustion intake . The exhaust is outside of the the cover .
The simple controller I mounted on the bulkhead between the fresh air vents . I just got around to connecting the wiring last week, just in time for the first snow and was doing it outside when the snow started
So to save time I took a live feed from the battery to a simple on off switch to power up the controller, otherwise there would be power to the controller all the time and given that the Landy doesn't get heavy use, the small draw that illuminates the controller could drain the battery.
I used one of the unused switches on the dash as the on off power switch. so no holes drilled and nice and simple.
So how well does it work. First off it wouldn't fire, the problem was found to be air drawn in just ahead of the pump. Close inspection showed that the rubber hose supplied with the heater had perished, despite it never having had fuel through it or being exposed to UV ,its just garbage Chinese rubber so throw it in the bin and fit some decent rubber hose to the thin plastic fuel line.
With the rubber hose replaced it was clear to see that the fuel was now passing through the pump with no air bubbles.
After that the heater fired right up , I messed about doing other stuff for 10 minutes but when I went into the Landy it was toasting, bear in mind its a 109 with rear bulkhead removed, It does have a lot of insulation but its still a big space to heat . . I've fired up the heater a couple of times now and so far it has always fired up without a problem . Ive driven the Landy with the diesel heater running and it didn't phase it either .
When driving with the heater running the noise is incidental, the trans noises drown out the heater 2 to 1
. with the engine off and the heater running at full tilt the noise isn't to bad just a steady low pitch drone..
Regrets .. I bought the simple controller for ease of use , but it would be an advantage to be able to fire the heater up from the house .. but that would mean the controller would need to be live all the time. ? The reason I fitted an on off switch so as not to drain the battery with its constant backlight . But thinking about it, the draw must be pretty low ..
Sorry to drone on with my annoying Scottish accent lynall ..
