Looking at where to place an external boiler, and some guidance on best practice is needed! Very conventional system - heat-only oil boiler, fully pumped, Y plan, indirect cylinder, F&E tank, 7 rads, all in a 2 bed cottage. It's a spring-supplied system, not on mains, so there is only 0.5 bar...

Hello all, I’m pretty clueless when it comes to this sort of thing but as we can’t have tradesmen in the house due to shielding I’m hoping someone can give me advice to help diagnose my heating problems. We bought this house less than a year ago and starting to find that there are several...

I am adding radiators to my 2-pipe pumped, vented central heating (UK). The whole piping is copper 22mm and microbore, and I'm extending it with 15mm pex barrier pipe graded for central heating. I know that the first bit of pipes connected to the boiler must be copper, which is the case...

Hi all, Sorry the title should have said problem not program! My Honeywell ST6400C central heating and hot water programmer has just gone wrong. I took it off the base plate and cleaned out the dust then put it back and pressed reset.Now I can set the date and time and programme in the heating...

Hello, I woke up this morning with the boiler flashing every 0.5 secs after realising the water wasn’t heating up. I have tried leaving the filling loop open and only fills to 3.5 bars. I have bled all my rads and it is now at 1.5 bars but I still have the same issue. No heating or hot water...

Hi all, Drayton ZA5 valve seized the other day during this Corona lock down. Took off the actuator head and sprayed the tap itself with silicon lubricant, but no luck, still too hard to move with pliers. Only thing that freed it was WD40. I am now terrified the WD40 is gonna eat the seals...
