Amazing how helpful everyone is here! Thank you.

Thank you so much! As soon as i read that it made sense - definitely one of those penny drop moments! All wired in and working now! Thank you so so much! Totally understand your point. I had already gone OTT with a zone valve! Its all working now so will just leave as is. Thanks anyway!!

Can i not wire the zone valve in as a second actuator? Or is there an alternative solution

The rad runs off from the 22mm flow and return just before the manifold on its own 15mm circuit, with a motorised valve just after it splits off. The motorised valve is manually set to open, so at the moment it turns on whenever the boiler kicks in for the central heating. That motorised valve i would like to wire into zone 3 as if its like a second actuator, if you see what i mean? i just cant figure out how to wire the thing because theres 5 wires from the valve...

The radiator currently runs off literally just before the manifold, therefore at 80c. I dont mind running it on its own stat, but would rather have it on the same stat as the UFH in zone 3, if possible?

Hi everyone! For the past year i have been doing a complete renovation of a 1930’s semi. Completely gutted it back to brick and started again. I have done almost all of the work myself apart from the extension at the rear. I have learnt a hell of a lot along the way, (with plenty of mistakes too!) but what i have learnt will be forever useful in the rest of my life. Im excited to see you all around the forums and hopefully i may now be able to help others too!

Hello all, I have been doing a big house renovation over the past year. Part of that is teaching myself UFH systems. So far i have 5 zones - zones 1-4 are UFH and zone 8 is the radiators upstairs. The problem i have is that zone 3 (the hallway) is not providing enough heat to heat the hallway. The house is an old 1930’s semi with minimal cavity insulation, so it gets cold quickly. Because of this, i’ve installed a radiator in the hallway and would like to somehow get this running on zone 3. The only way i can think to do that is adding a motorised heating valve to zone 3, however the valve has 5 wires and i cannot figure out how it should be wired. Im using a Heatmiser system with a UH8-RF wiring centre. the motorised valve is a honeywell. Does anyone know how i can wire this, or have any other ideas how i can get that one radiator to activate with zone 3? Thank you so much for any help, my mind has gone mental trying to figure this out!
