boiler

I recently installed a new radiator in the upstairs bathroom to replace a beastly radiator. During the installation process, I drained and filled the system three or four times during the installation process. (The water color was typically darker but flowed.) The new radiator is working great...

I got a brand new Worcester Bosch Greenstar 27Ri gas boiler installed in May and haven’t had any issues with it actually working, except since we started using it regularly we’ve noticed it seems to make a loud noise when igniting (I wouldn’t say like a bang but more like just a loud vibration)...

Hi All, Having a couple of issues with the central heating which I want to clear up before the temperatures drop. I run the CH via a thermostat. It’s set for 18.5 degrees and in the day it runs absolutely fine, if it drops below, the flame symbol comes on on the thermostat and the boiler fires...

Hi, I've just changed from a EPH thermostat system to Hive, just wondering if anyone could help in matching the wires up for me, are they installed correctly? I've attached 2 photos showing the change I've done between them, thanks

So a couple of weeks ago we noticed the boiler making this noise (see vid), its much louder than we've known it to be, and there seems to be condensation or steam coming out of the hole in the top. Strange thing is that it only makes this noise if we run the bath, the sink taps or heating do...

I have inherited a house with a Flexicom 30hx boiler (heat only). With a cold house and plenty of demand, it operates rather strangely, where it will run at full tilt for 30 seconds or so (up to ~80c flow) but then you can hear it stop, and it cools down for a long while, before then having a...

Hi, I had a Vaillant ecofit pure 830 combi installed at the beginning of the year. Flushed and new protection kit fitted, etc. Came back from a 2 week holiday and now I'm getting a horrible loud pulsing noise that vibrates through the house. Happens with both ch and hw. Have attached a short vid...

So we took a radiator off the wall on the weekend in order to paint the wall. Turned off TRV and lockshield valve, drained the water from the radiator etc. Capped off the TRV but it appears that it still kept leaking through the cap (I guess the valve doesn't close properly, never seen that...

Hi Sorry for another expansion vessel question but I can find this asked previously Had my boiler service yesterday and the engineer said it is full of water and it needs to be drained. He didn't mention anything about having popped. I pressed the valve and zero water came out. I replaced the...

Hi all, Having some issues with Nest or boiler not sure what one is causing the issue. It’s a Biasi advanced 25c boiler with Nest 3rd gen thermostat. Basically been working fine for the 4 years it’s been installed, went to test it out a few weeks ago and it wouldn’t fire up in manual mode but...

Hello, I moved into a new flat and have an electric Strom boiler for hot water and heating. The hot water is fine, but when i switch the heating on the temperature goes up and up and when it reaches 50 it switches the whole system off. the overflow light also goes on. I usually get a few...

If I turn on the hot water, the boiler starts up first time and works fine, but it is completely unresponsive to me turning on the central heating. It doesn't make any sounds, no flashing lights (just power on, and flame off like it's still on standby). Is there anything obvious I should...

Not technically a disaster, but felt this was the most appropriate section of the forum. Just a story from a now retired plumber in my family. A long time ago, a plumber in my extended family (now retired) got a call from someone saying they could smell gas in their home. When he got there, he...

Had a short power cut earlier and when the power came back on, it looks like my Vaillant Ecotec 937 plus boiler died. My educated guess is either when the power went out or when the power came back on, the PCB on my boiler died, as now it is completely unresponsive (LCD dead, no heating or hot...

I have just brought a hive and need help with how to wire it up to my existing system can someone please tell me where to transfer the wires in the image attached : N L L A B Many Thanks

Hi All New house, new boiler! The set-up is: - Vaillant Ecotec Plus 637, system boiler single plan - Tank elson zircon 250zi, no immersion - Programmer Drayton LP722 (dual channel, heating and hot water) - A Salus controller, not too sure what does is used for. As you can see from the PCB...

our boiler pressure is dropping to 0 even after having the blender valve replaced, paid £80. Maybe 2weeks ago. This was when our pressure was at 0 and only cold water was coming out. Now my water is going hot and cold every 15/20 seconds from the bath tap. Any ideas only moved in a month ago

Hello everyone. I've recently moved into a flat and it has a vokera boiler. We've noticed the smell of gas whenever we switch on water, and I've noticed it from another flat as well. We had a boiler check and the engineer didn't find anything wrong or concerning but did not comment on why I'd...

I have a Baxi system boiler in my garage which is connected to the pump and tank in my airing cupboard via Hive.. It has decided to stop firing up for some reason. I have checked the hive system and everything is working fine. The thermostat is talking to the receiver in the airing cupboard...

Hi all, Apologies in advance if I get any terminology incorrect. I moved into a house about a year ago with a system boiler. I've always lived in houses with a regular/conventional boiler system so I'm still getting my head around how a system boiler works. I'm looking at doing some...
