Hi
If the radiator valves are not demanding much heat and are near closed then the automatic bypass should be cutting in.
I have a few queries that may be obvious but not to me as old system did not have an automatic bypass.
[1] When it comes in it is shunting some of the hot water, will this not mean that the zones that do want a bit of heat are robbed of it?
[2] When it comes in and it starts to get hot (shunting the water) will the boiler not see a higher return temperature and think it needs less heat (or stops the burner) again meaning no heat for the near closed valves that require some heat?
[3] When it does cut in, how hot is it supposed to get?
[4] When it does come in then it seems noisy as the water is gushing through it - is this normal?
At the moment I have set it high and using open radiator instead (but that will be upping the gas costs so I would like to get the bypass working correctly).
Thanks
Colin
