Eufy cameras get decent reviews, I am thinking of swapping my Ring cameras for Eufy.

Good point, I forgot about the return :eek:

Presumably in this weather you are only heating the HWC therefore the radiators are isolated at the motorised valve. This suggests that the "leak" is somewhere in the boiler or the hot water circuit.

The Wiser zigbee is proprietary.

Are you on an s plan or y plan?

When I had my WB system boiler installed the installer fitted a Honeywell DU145. To set it up all he did was shut the ABV off fully and with both motorised valves closed adjusted the ABV until he felt heat on the return pipe connection.

You’re the only person that thinks it’s wrong though.

I think you’re letting this get overly complicated. Don’t worry about the 20c drop across a radiator as no one gets that anymore. Are you using TRV’s on the radiators, if so that messes up the radiator temp drop as well so just ensure the radiators are balanced and let the TRV’s do their thing.

There are ems to open therm converters available but their compatibility with your particular boiler would need checking.

Have you thought about temporarily replacing the ABV with a gate valve. You could then run all your tests with the gate valve closed but still be able to open it if the boiler complains.

Any reason why you are repiping as an s-plan system rather than PDHW. With all the work you are doing now seems like a good time to replace the boiler with a pressurised system boiler that supports PDHW.

You are of course correct but if you look in the boiler manuals there is usually a section that states what the manufacturer expects a service to be but IME with my boiler this never happens therefore the boiler warranty is actually voided by the person doing the basic service. Luckily I doubt a...

Get a Vaillant thermostat. None of the aftermarket ones will be as good.

A couple of observations for @ericmark ….. The Wiser system needs comfort mode turned on in order to work out when to turn heating on before the temperature setpoint change. This mode is off by default. The wiser graph is inaccurately plotting when the temperature rises, mine does the same. It...

Here is a thread with this same issue on another forum, looks like WB have an issue with these boilers…. https://forum.buildhub.org.uk/topic/46179-worcester-bosch-greenstar-8000-system-boiler-issues/
