I’m looking at how to connect up the UVC which is part of the Genvex Combi I’ve just bought. The UVC is heated with an EASHP which will heat the water to a maximum of 55C. It has a 1kW immersion to increase the temperature if required. Genvex say the maximum tank temperature should not exceed 65C. Reading up on safety devices on the internet it says there should be three independent ones. It looks like the Combi has two manual reset thermal cut outs with 80C stamped on them. Does that mean I would need just a pressure relief valve to have a safe system?
The top part is an anode, under that two reset buttons and at the bottom the immersion.
