Hi All,
I just had a new Vaillant 630 system boiler fitter with Megaflo cylinder and underfloor heating, it has 3 Honeywell motorised valves fitted in total in a out house.
My friend has the setup but the only difference is that he has a auto bypass thingy, so i asked my plumber why mine wasn't fitted with one. His response was that these boilers already have a built in auto bypass
Should I call him back to fit this or is he correct that I don't need one.
Thanks!
