  • Hi All, Combo Gas Boiler – Immergas Zeus Mini I’m hoping you can maybe help me with an intermittent issue I’m having with my Immergas Zeus Mini Combi Boiler. It works for weeks and then has a sporadic issue with igniting the boiler? I’ve uploaded a video so maybe you can take a Quick Look […]
  • My 10 year old Vaillant Eco Tec Boiler pump/fan occasionally turns on for 10 secs when the cold water supply is turned off at the tap or toilet after use. If the tap is turned off slowly, it doesn't happen. Any suggestions please?
  • Can anyone recommend a good quality filling loop brand? They all seem to be cheap and flimsy with plastic handles. Altechnic is ok I find, the water side is good with a nice metal handle, the heating side is poor.
  • I need to replace 2 of these valve bodies & head but never come across them before, the TRV threads into the radiator thread not sure if I can remove TRV valve body from TRV and this will fit thread of radiator. Customer doesn't want to replace the radiators as they are unique seat type […]
  • I've recently had a Baxi heat only boiler fitted and just noticed there is excess water coming out of the flue. I obviously will ring the company to get them back. I just wanted to get a bit of information beforehand. Can these flues be repositioned? On mine you can see the water pools forward […]
  • Hi, just had a Drayton lp112 programmer fitted. Now when the hot water is programmed to come on the central heating comes on as well, even though it's not selected. Is it possible that the programmer wired wrong
  • Hi there Well after my last posts, we have a new ufh manifold and return temp is good. But we still have an issues with the water being blown out the condensate trap when the boiler starts up and melting the condensate pipe. We have a .65 80s nozzle, pump pressure 12 bar, air set […]
  • I have a ferolli HE31C and it has developed a water leak that appears to be from a porous casing in the gas valve. I can not see where water even enters the gas valve as I presume the gas goes in the bottom and out of the top of the valve. To check this […]
  • Every two weeks or so I have to go and top up the system because the hot taps are running cold. Boiler display is flashing 0.6 bar and I fill up to 1.3. I've had an engineer look inside the boiler and he can't see anything wrong. I've checked the pipes all over the house […]
  • Our boiler is in the loft and I encountered a leak in a roof above our side extension store room which has transpired to be from the boiler condensate pipe. It was cracked at an elbow so the plumber we use has replaced this and hopefully all will be well with that joint. This later […]
  • Had a power cut now alpha gas saver 34c boiler is dead. Any ideas please
  • Under a boiler replacement grant I've been offered a Baxi 418 heat only. Has anyone any experience of this model? Apparently it has an aluminium heat exchanger but a lot of parts are combined into one so maybe costly if repairs are needed. Thanks
  • Hi I have a 5 year old Vailliant boiler and for the past few weeks the hot water has been coming out scalding hot. I have tried turning the dial down on the front of the boiler but it doesn't seem to do anything. It is so hot that even with rubber gloves on my […]
  • What is the boiler flow temperature required to flag this 2965 fault code?. This, I believe, is a blocking code that trips the burner but when/if it resets. the burner will refire without any boiler reset? If this fault code is up while in CH mode and there is a demand for HW, will the […]
  • Hi all I have a britony combi se 80 with fault 40 60 80 had british gas out to repair under homecare cover but they can't seem to repair it. They have been out 7 times so far and fitted a new pump heat exchanger air pressure switch and a pcb. Does anyone on here […]
  • Hi, Later this year I am going away for a 2 week holiday and as the weather will be warm there is no need for the heating to be on and arguably no need for me to needlessly heat hot water. My intention was to turn the boiler off along with the mains water when […]
  • I have a heating system comprised of skirting radiators that form part of a loop from the boiler, round the house and back. Some rooms get warmer than others despite closing off the skirting radiator heat vent. They are designed to house the finned heating pipe and a return pipe, the latter position being empty. […]
  • Hi, I was hoping to replace an old system boiler with a Vaillant Ecotec Exclusive 627 system boiler, thats the one with the diverter valve so no need for zone valves, controling it with a V-Smart and a VR10. I've spoken to Vaillant Tech and they said you cannot use the VR10 with a vented […]
  • Apologies if this has been answered elsewhere, but my family and I are starting to crack. I'll start at the beginning, and maybe someone will see something that makes sense to them. We live in a council property, and a couple of years ago our boiler (a Promax 28 Combi) started flashing us the good […]
  • Ideal Logic 24, Previous problem was that the hot water was only cold or barely warm if the heating was in use. If heating was off and boiler cold then would get hot water most of the time. Changing the flow cartridge about 2 years ago (when I moved in) solved this problem enough to […]
