I am having a problem with my main 24he boiler where the flame is constantly clicking on and off with the heating and when using hot water. Some times the flame failure light comes on but it ignites again after a few seconds. The plumber has changed a couple of sensors on the boiler and checked...
Hello Plumbers
I’ve replaced a 540mm high cast iron rad with 740mm high, like for like but still a 20mm valve extension was required.
All was ok until I've spotted a v small leak (like 1 drip per hour) between the valve nut and extension piece.
So I suspect I just need more PTFE + compound...
Hi need some advice on this odd story, I had a Bosch boiler installed just over 2 years ago by Governments home energy scheme. The company passed all checks, provided certs etc.
The government/Green scheme sends 2 other gas boiler engineers to double and triple check things and One was Bosch...
I've got a Glowworm Flexicom 24hx boiler and I'm trying to unplug the installer cartridge in order to wire up the ebus connection inside.
From what I've read, it should be possible to do this without opening the boiler, but there is limited access around the boiler and I'm struggling!
From the...
Got some quotes for a service, one person has said if I haven't had the burner seal replaced for past 5 years, it should be done (& service price goes up by £55).
Boiler installed in 2015 - never had the 'seal' replaced? Is it a necessary requirement just as a matter of course?
Hello, i'm doing some heatloss calculations, going by a fairly old plumbing book.
The formula for calculating heatloss would be Surface Area x Temp Diff x U-Value = Heatloss
My question is, when calculating the heatloss through a ceiling, so downstairs to upstairs, the temp difference would be...
Hi,
I am looking for a bit of advice. Our Gledhill hot water tank was installed incorrectly 18 months ago and has been sending bubbling hot water to our plastic header tank in the loft every time we turned the heating on. We first noticed an issue with a leak in our bedroom ceiling which we...
Trying to find out exactly what happens when my system boiler is called to supply the radiators and hot water cylinder at the same time.
For example today, whilst the boiler was on heating the water, the room stat triggered the boiler to supply the rads. The diverter valve installed in the...
My disabled daughter’s hot water has stopped working. It’s a relatively modern Potterton boiler with an indirect sealed hot water system and a Nest controller. I’m familiar with the old gravity and pumped hot water systems and the new direct systems but not with sealed systems.

Hi, I note that the Grundfos Alpha 2 requires a special plug to connect the electric wiring. Are those plugs reusable if rewiring is needed? It's an expensive plug, costing as much as a used Alpha pump. Suppliers of refurbished pumps don't supply a plug. Fine if it is a Grundfos like for...
Hi all.
I recently upgraded our CH system, but rather than the expected drop in gas consumption, Octopus is saying we're using roughly 30% more! The installer has said they can downrate the boiler, but to my mind that addresses maximum consumption, not any inefficiencies there may be relating...

Hi

Boiler throws up a flashing 79 code.
Try restarting the boiler straight away but I have to wait 10 minutes for it to cool down before it works.
I reset the boiler...
Hello, my Mothers heating failed in the recent UK cold snap. I found the pump was stuck. I have a question about pump orientation. The existing pump flows downwards. The manual for the proposed replacement recommends that it should pump upwards. This would involve rearranging the flow &...
Hi
How does the weather comp. work when you go to bed.
If you have a lower temperature at night surely the next day the boiler then has to work that bit harder to reach the correct temperature for that day. What do you do?
hello me and another student have just moved into a flat that has a Hortsmann Economy 7 Boiler. currently the timer is set to run for 7 hours with it turning on at midnight and switching off again at 7am. because there’s only two of us this is way more than we need and the amount of time the...
Had conventional boiler and tanks removed last year and new combi fitted and just recently had it serviced but the guy who did it has given me a gas warning notice for at risk as the outside wall meter box has been drilled through for the gas pipe to go horizontal straight to the boiler. The...

I have a 2 pump hot water tank (Flomax 180L fitted in '94) in airing cupboard system with an Ideal classic boiler (downstairs next to an external wall) which for the most part seems to provide excellent hot water. The central heating also works fine - though sometimes I think the radiuators...
