Gas Boiler Flow/return Temperature Difference

John.G · 2021-01-11 20:59:22

Can anyone out there who has or services gas fired UFH only or UFH & rads have a look at the flow & return temperatures (where available) when running on UFH only as I see that some boilers go into waiting mode with burner off when this difference exceeds a certain limit, at around 28/30C, I think.

Glowworm are a dope for throwing faults when flow is too high or you don't get the difference in temp
