Hi,
We currently have a gravity HW & pumped CH system using a Thermacon Option 60/80 floor standing oil boiler which is currently setup to always run HW+CH. There's a motorised valve on the return pipework from the HW cylinder to the boiler, but nothing on the CH side. It's around 20-30 years old and is open vented with a feed/expansion/header tank in the loft.
The HW cylinder is a standard indirect / vented cylinder and was fitted about 4 months ago. Cyl flow/returns are in 28mm copper reduced to 22mm at the cylinder. HW flow/returns are 22mm.
With summer hopefully coming up we're looking at upgrading the system with the intention of hopefully being able to run HW on its own, or HW + CH rather than always needing to run the radiators.
Is this possible...? Is it a case of adding a motorised valve on the CH side & upgrading the controls / programmer to one supporting HW/HW+CH, or would more substantial alterations be likely?
Thanks for your help,
Tim
