Hi friends, downstairs we have wet UFH with the HCC80R + daughterboard running six zones each with DTS92E thermostats. Upstairs we have 4 DTS92E, with between 1 and 3 radiators bound to them. We also have EvoHome controlling the hot water, which is stored in a pressurised tank.

Can anyone offer some advise on how best to configure for boiler efficiency? Itís fair to say our installer was not an EvoHome expert.

Currently, I am coinciding the zone heating with the times at which we heat the water (logic being that boiler is already one), but I donít know if this is smart or not.

Can anyone offer some wisdom?

Thanks, Tim

PS. If anyone knows a Hampshire-based engineer, Iím happy to pay for a visit.
