It really can’t be that complicated.
Most of the window cleaning suppliers sell them as a one box system.
Surely it cannot be that difficult to connect up to the system.
My diy knowledge is pretty good, ive renovated my house, new central hesting system, en suite from scratch including all soil pipe and ground works to man hole, new kitchen fitted etc etc. I’m no engineer, but I simply don’t understand how fitting a diesel hot water heater in the van with a few hoses is complicated?
I may be missing something, because there is very little information available on the fitting of these heaters. I am assuming (perhaps wrongly) it is a one box system with simple connections in > out > recirculate and then the electrics to the battery.
I’d like to know what is involved, I’m not going to tap into my van diesel tank, rather use its own small tank.
