Grant combi and zoned heating

coopersim · 27 Nov 2013

I have a grant combi with seperate piping for each floor, I would like to know if it is possible to zone it without prised valves as we have a wood burner keeping the downstairs warm.

We have a Honeywell wireless thermostat and timer unit - st9120c[/list]

Yes. 2 port valve in the flow to the ground floor will drop the boiler heating the downstairs.
Or just a simple 22mm gate valve you can turn off will do the job.
