Whats the best way to heat water before it gets to a Mytee, whilst 'sited' in the back of the van? I know the Mytee's have 2 heat exchangers but stone cold water might not quite be enough.
So, I was thinking of using an immersion heater into the solution tank (so it can warm up a bit whilst on way to job) via an inverter, or alternatively running a heat exchanger to warm it up as it leaves the tank using the same inverter (or use the custys electric instead).
Any ideas?
