mattyg 1,862 Posted July 20, 2016 Report Share Posted July 20, 2016 After a bit of advice, home from a short break abroad and thought the house was a bit warm even for the recent weather, the heating hasn't been on for ages obviously but the Mrs notice a few of the radiators were warm......any ideas? I've switched the boiler over to water only for now. Cheers, Matt Quote Link to post Share on other sites
ArchieHood 3,692 Posted July 20, 2016 Report Share Posted July 20, 2016 Google says it could be a 3 way motorised valve not operating properly and allowing the primary feed to heat the domestic hot water and the radiator feeds at the same time. 1 Quote Link to post Share on other sites

kanny 21,784 Posted July 20, 2016 Report Share Posted July 20, 2016 (edited) I'm not a plumber but lol ....if your heating system pipes and your hot water pipes run side by side heat can transfer From one to the other ivd had similar but in reverse ...we never have the hot water on as we have electric shower dishwasher ect we just have no need for it ...its a waist but when we put the radiators on we can get warm water from the tap my Bruv inlaw is a plumber and he told me it was just heat transfer.
