Been working on my folks heating system (sludged up radiator) but can't understand what's going on. 1990's professionally installed oil Worcester Boiler system with gravity header tank. Hostmann Tiara Controller. One single two way Honeywell diverter valve. No roomstat but stats TRV's on radiators. What puzzles me is that there is no stat anywhere on hot water tank or the lines and nothing obvious feeding back to the diverter valve? The Tiara controller has two sliders but you can operate Hot water only, or heating with hot water; not heating only. Big dial on front of boiler to turn hat up, but that will increase heat of hot water also?! So what is the diverter valve actually doing, any suggestions? And how simple would it be to convert this system to a Y plan so I could have sep heating and hot water............
Any explanations very welcome please
