Hi first time post so I hope I'm not repeating something.My hot water is coming out of the taps at 90 degrees with the tank stat set at 50! I changed the stat for a new one but does not seam to have solved the problem.There is no electrical current going to the stat although there is current at the junction where stat,2 way valve and mains,I think, join up.What could be wrong? System is fired from a Baxi Bermuda back boiler.Many thanks.
