Hi, whenever my Gloworm 18r is on even if I leave it on non-stop for 6 hours the flame symbol for the burner never switches off and the radiator icon never stops flashing implying the rads are calling for more heat, even though they're all red hot and have been for hours, is this a fault or just...
Hi All,
I hope you are doing well.
I have old un-pressurised heating system and I need to top up the water but I cannot locate the bloody valve.
Where is it? Is it in the attic?
I also have this valve with black screw on top. Should this be opened or closed?
Thank you
I think the last discussion was back in 2021.
A few questions to guide any discussion.
Which are the cheapest to heat over the year, system or combi in an average 3/4 bed property?
Which will be the more reliable and cheapest boiler type to repair over the next 10 years?
Is there a better...
Hi Folks,
I have a challenge with a Main Eco Elite 30 Combi which is short cycling on the CH. Water works fine. As soon as you have call for heat, the boiler fires up, modulates, but jumps very quickly (about 30 seconds or so from 40'ish all the way to 70, burner disengages putting it the...

Hello, I have a ferroli falcon 2 boiler (yes it is pretty old). A few days ago the hot water started going hot and cold when running.
Monitoring the boiler, the demand light works fine. When the water gets up to temperature every 10 seconds or so, the boiler stops for a fraction of a second...
In our sealed Megalo system, when hot water tap is used (say in bathroom shower) the megaflo is taking in some fresh water, I guess to compensate for the water used. The incoming water go via a pressure relief valve [most likely its this one: Heatrae Sadia 8 Bar Pressure Relief Valve -...
Heating and hot water is not working. Plenty of heating oil. I have replaced batteries in thermostat and it seems to be working ok, showing flame to call for heat, and the receiver seems to be working ok with green light, but heating is just not firing. I really am not sure what the problem is...

Hi, I am replacing our 11 year old boiler (due to H.Ex. leak) with a new one. This is in a "sealed" system with red expansion vessel in airig cupboard & a megaflo (no tank in loft). However the exisiting boiler is Vaillant ecoTEC 4xx boiler - which is satated by vaillant as an "open vent" boiler...
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. New here. I dont know nothing about boilers or plumbing. Just wondering any idea of cost or what the issue is. 15y old boiler, never had any issues apart from heater exchange smal leak 2y ago, BG changed whole heater exchange and some other small leaks.

Hello, bit of a noob question but would someone be able to help me to understand the pipes coming off our boiler. It's a Grant oil combi boiler, and where the pipes come in is in a room at the front of the house. I am about to box them in but I really wanted to understand what the various pipes...
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?

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...
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...
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...

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.

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, 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...
