Hello lovely boaters,
I'm most of the way through installing my heating system, I have a 75L calorifier which will be heated by the Webasto Thermo Top C. The Webasto will then go on to heat a load of rads.
My question is, does the header tank have to be at the highest point. I fitted it without giving any real thought and now after thinking about it I would imagine it needs to sit higher than the highest radiator. Is that right or can I get away with having it around 30cm lower than the highest point in the system.
The header tank is currently in the engine bay, nice and out of sight. I will have to move it inside the utility room if it needs to be higher, no real issue just a pain in my arse, a pain I would rather avoid.
Help is much appreciated.
Beau
