I'm hoping someone can help. I've got an open vented y plan central heating and water system with tanks, pumps, valves etc. My previous boiler only had a flow and return. It packed up a few days ago so I purchased a cheap iqe system boiler to replace it as I really wanted a Combi but that's not a job I want to do just before Christmas. This iqe boiler has a dhw flow and return and a central heating flow and return. Now for the system I have I was told I can cap off the dhw f&r and use just the central heating f&r. I have done this but the boiler is faulting as the water pressure is too low. Should I have used the dhw f&r or is that not possible?? Please help need some heat for crimbo lol
