central

Good Morning. I've been having an issue for a couple of days, that my nest thermostat is demanding heat, but the boiler does not activate. However, when using the heat link manual button, the heating works fine for around 2 hours. I have recently replaced the pump from a wilks gold rs50 to a...

Can anyone tell me if I have a central heating filter? I have a glow worm micron 30ff with a tank in the airing cupboard and a tank in the loft. I know there is a Grundfos pump but I cannot see a filter?

When putting our CH and HW on, it’s sometimes a lottery as to whether the central heating will come on. The HW works every time with no problems. Furthermore, when the CH does come on, sometimes only half of the radiators in the house come on - when this happens, we switch CH/HW off and switch...

Hi, I have a question about my s plan heating. I have a Worcester 35cdi erp boiler connected to 2 heating loops and an unvented indirect cylinder via 3 switch values. If I have the radiator heating on and water heating on the system doesn’t close the heating or water switch values. So doesn’t...

The majority of joints on my central heating system are threaded, apart from a few that are push fit. However, the drain cock is a soldered fitment, so the question is - why is this soldered (unless on some older BSP systems) when a threaded joint is suitable for everything else? Just seems...

The small bore pipe to 4 radiators was completely clogged up. One radiator stone cold , others barely luke warm. Those plumbers that bothered to quote said ‘power flush’ but would not guarantee any success. So I tackled it myself, ripped up the floor boards and traced back the small bore that...

Hi, looking for advise about freezing a pipe on the central heating system. I’m adding a new radiator to the system in another room and thought that a good way would be to freeze the pipe where I need to take off and return to the other pipe. I will be using push fit joints. My question is if I...

Hi, sorry this is so long. I have tried to give all relevant info. We are building a new, small, two-storey house that is off grid for power. There are only a few companies that do central heating systems locally, and they are aimed at the very top end of the market. We are at the lower end of...

Hi. This is part of a narrow L-section of an upstairs bathroom in a house I'm renovating. The toilet sits here. I forgot to take a pic whilst up there, so I've drawn a diagram. Black = walls Brown = joists Blue = CH pipes (hopefully) - they're already notched in this location but unused. I...

Hi, I require some advice on two issues. I have a Worcester 24cdi combi boiler, my kitchen mixer tap only gets hot water when I turn central heating on. The toilet hot water works without needing to turn central heating on. I recently increased the boiler pressure from below 1 to 1.5, could...
