this is for you a900!i bet it ends up longer than the hydroheat thread over the next month or so! ;D

Simon Trapani:
Yeh it’s got me interested today cos it’s bloody freezin!

a900:
Haha. Better start trying to work out how to get these photos uploaded. Somehow I can upload PDFs.

For anyone interested. First one shows the size of the heat exchanger I used. I used one this size because I didn’t want one that was 2 small and not knowing what would be 2 small. So basically looked for one that was the same size as a Webasto plate heat exchanger or larger. When I add a second it will be much smaller to fill a gap on my board. As I really think it’s larger than needed but for the main hose I wanted to make sure I got the hottest temperature I could.

I’m working on a recirculation that switches the pump to a low speed the same as 11 on my controller and diverts the water back to the tank. So when I finish a job and drive to the next one or get distracted chatting with customers I can keep the heater idling so it doesn’t shut down. (Learnt they use less fuel this way) This will be on a switch for now but might use a wireless fob and control the electric reel with it too. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F131730091890

This will save me time turning my pump down and plugging the reel hose in to recirculate every time the van is moved.

Frostat to come. Which will use most of the circuit set up for the recirculation but use a little board that you can get for £2 that can turn the pump and heater on and off at whatever temp I set. https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F283139826056
