Cheers for the reply’s guys. Sorry I missed the valve for the h/w it does have one.

You need to tell us.
so you have 3 heating zones (2 downstairs 1 upstairs) each one with a valve and controlled by a room stat
1 H/W zone valve controlled via tank stat.
two pumps one for the system? one for secondary return?
Is this correct?

 

[Rob brazendale]

Hi Antony this is correct. They want each zone to have its own room stat if this is possible. Cheers

 

[Toneyz]

Has any of this been wired or plumbed?

Hi Antony this is correct. They want each zone to have its own room stat if this is possible. Cheers

Yes one room stat to each valve one tip ask the plumber which valve does which area and mark up each stat. Look at Lee's wiring diagram. Ask the plumber what each component does and post some photo's if possible.

It’s all been plumbed up. I’ll draw up a diagram and post it on here. Cheers

 

[Rob brazendale]

It’s ok been plumed in. Cheers I’ll draw up a diagram and post it on here. Thanks

What are the two pumps for?

What are the two pumps for?

This is what I was trying to find out from the OP, Lee we think one is for the system and the other is for secondary return but waiting for the OP to confirm from the plumber.

If it’s a secondary return it should be obvious as it will be plumbed into the cylinder secondary return...The pump will have bronze or SS impellers and the housing is usually yellow if it’s a grundfos pump.
