Always buy fire insurance a flood is hard start FS

Nobody tried the big 100/150 and venting exaust into that a Lot of feat goes out of exhaust, it does work
I had mine installed for 3 years now power supply plugged in and have shut the power off a couple of times in error not letting it do the cool down procedure this it did no harm at all. I wouldn't do it all the time but if you do knock the power off in error don't panic, it should be OK.As premiered above, it's in and it works!
Youtube video below but here's a couple of pics and some thoughts...
First off, these are great value for money. They are fiddly, and the instructions leave something to be desired (although I got a better than usual set of instructions, available over here)
It's early days but so far it's working extremely well. My garage is well insulated but (smiley face) has plenty ventilation gaps deliberately set out and (frowny face) has a bog-standard metal up-and-over door.
That said, an unscientific test in 2 degrees C external weather earlier in the week raised the garage temperature from 4C to 13C in around half an hour.
The whole diesel pipe fitting scared the crap out of me (but then anything to do with plumbing scares me) so I did buy jubilee clips rather than relying on the pinch clips that came with the kit.
Building a harness was essential, IMO. This allowed me to figure out how the inlet and exhaust hoses would work, where the fuel pipe would route and how I would fit the power supply, fuel filter and full pump.
As an added bonus, I went with 8mm steel dowel to fix it in place rather than screws or bolts so that I could easily fit and remove it. The video has a bit more info on that.
I have wired it directly to the mains (via a power supply, of course) and didn't use the apparently-recommended route of using a car battery to provide an "uninterruptible power supply". I can see why this could be beneficial but the additional mess and complexity of managing a lead acid battery (or similar) and its charging seemed over the top for my use case. I'll be in the garage when I turn the heater on and will nurse it through its shutdown process. In the unlikely event that the power is cut during this process then my worst case is spending £100 on replacing the heater unit, but I personally (your mileage may vary!) have never been in a situation where this seems likely.
All in all, I think these are great buys but the installation definitely tests your metal in terms of fabrication, heat management, electrics, and combustible fuel storage & routing. I'm glad I did it and, in hindsight, would be far more comfortable if I had to attempt it for a second time.
I can get more pics if people are interested, especially of the harness, but I hope the video helps anyone else thinking of installing one of these.
