boiler

Main Combi 25 Eco There is no system filter. 3 rads - whole install (pipes & rads) were new at the time. About 8 yrs old. Hard water area. Central heating can be on for hours - no real issue. But, If I then turn thermostat off - as I am going to have a shower - and turn the shower on (hot) -...

Hi, last night our central heating system seems to have developed a problem. Our boiler is an Ideal Logic 15. It appears that the thermostat is working fine (?) but somehow the boiler thinks there is a constant demand to supply heating. For example, thermostat currently at 20c and the flame...

Hello everyone, My home has a BAXI DUO-TEC COMBI 24 HE. The radiators won't heat up even though the boiler is showing a green light saying they are running. The hot water is still working though. I've tried bleeding radiators and then pressurising the boiler after but I still have the same...

Less than a year now. Got new plumbing system with Atag I40s system boiler with unvented cylinder 210l. Compared to the previous old vented system the gas bill seems to have double out. Plumber set up hotwater to 65° and heating to 70° Can you please advise if the hotwater can be keep lower...

My boiler was fitted about 4 years ago. Its a Valliant Ecotec32 and was installed on the outside wall of my garage. I've demolished the garage now and a new one has been built. The flow, DHW and cold inlet pipes are all back in place and the gas pipe is about 1 meter away in 22mm. The pipes...

Hello, I have recently moved into a property with the thermostatic controls shown attached. I am currently able to switch the heating on continuous which is fine for now. However unsure of how the clock works and if it does work? Also the boiler seems to heat up the two radiators downstairs...

Hi All, Looking for some advice please! Not sure if this could be a DIY Home fix or if I need to call an engineer. I have a Vaillant Ecotec Plus 418, which appears fine on the hot water side and is able to maintain temperature however when I call for heating, initially it seems to go for a...

Hi everyone, I can see a few people had this issue, but its not entirely clear if or how it was resolved, so I'd really appreciate some help here. The symptoms are as follows: Open hot tap DHW demand light stays dark Display temperature remains constant/room temperature Water is cold Central...

Hi, I just lost all pressure in my boiler after I bled all the radiators in my flat. I have a Potterton Performa 24 boiler, and am in a flat on the 3rd floor in a building with quite a few other flats. I've attached pictures of the valves and pipes I have in the boiler. Please could...

Hi all, Newb here. I've been reading some of your threads and it seems there are some very smart folks here who may be able to help with a head-baffling question. We're in a rental home and we have a 20yo oil boiler, the Camray 5 95/130A. It's had the burner replaced with a Riello RD3 that the...

We had a new boiler (ideal Max 24) installed in April. Long story short, house is 20 years old and pipes are microbore copper 8mm. We have no heating or hotwater. New boiler has never worked great. Had power flush, new pump, new divertor and ideal engineer to make sure boiler was not faulty...

Had a greenstar 32cdi compact fitted years ago, after my old tank system failed. I had hive heating and hot water installed for the old system, as it would heat the water. When I had my Worcester installed, I kept the hive heating, the fitter said it would just work with the thermostat and...

Hello, I stupidly was fiddling with the isolation valves in my viessmann vitodens 050-W boiler and forgot which direction they go in, I have all valves open currently, the hot and cold water, flow in and flow out valves also. Is this correct?

Hi, hoping there's someone here who can help! Background: I have recently moved and inherited a Worcester Bosch HeatSlave 20/25 oil combi. It played up within 2 weeks of moving in, and I've had an engineer out to fix it - about 6 times! Several things were replaced, and the heating system has...

Hi I have a Worcester Greenstar 32 with a Megaflow unvented cyclinder and its been running great for he last 4 years. This week we noticed the radiators are not as warm as usual, for some reason the boiler heats up but doesn't get much above 50 deg before cycling on and off every few minutes...

Hi, We have just moved in to an old property with a Ideal Mexico 2 boiler controlled from a Horstmann Potterton controller. The timer function has just stopped working and I thought I could upgrade the potterton controller to a Nest thermostat with heat link. I think the Ideal Mexico 2 is a...

I have a combi boiler driven heating system and a mixer tap in the shower, the one with temperature control knob. After a shower, when I turn off the tap, it doesn't go to zero position but the water stops completely at say 30/100 position (100= fully open). Then after few hours, mostly in the...

Hi First time poster here. Looking to renovate old bathroom on 1st floor of 1950s semi and want to relocate bath to a different corner. Is it possible to plumb the bath drain into the condensate drain pipe fitted for a combi boiler? It's a 1.5 inch PVC pipe which runs out of the external wall...

The system is 10 years old. I have changed the Digistat battery after the icon started flashing but it still flashes. It's a new battery from a recently bought pack. I have already changed it twice but it is still flashing. Any advice please? Thanks

Suddenly the thermostat has stopped sending signal to put the heating on. I’ve tried changing the batteries.. The red light is flashing on the receiver and on auto. I’ve tried turning everything on and off again . Its not kicking in when I turn the temperature up on the thermostat the flame...
