boiler

Hello dear community, I need your expertise on a boiler with a pressure relief valve (not an instantaneous water heater). Since I am not very familiar with this, I hope for your help. I have an old boiler, which I have taken photos of, and I would like to know if a new boiler I found on eBay...

We are getting a new heating system but different plumbers are suggesting different boilers. Our house will be a 4 bedroom, with 3 bathrooms. We are a family of 4, 1 due imminently, 1 is nearly 2 and my wife and i. One bathroom will be downstairs and is existing having an electric mains shower...

I've been given conflicting opinions from different plumbers about the type of boiler to have installed (which seems the norm reading through the threads), so would greatly appreciate some advice. Some suggest a combi as my flow rate is only 10 L/m and others suggest an unvented cylinder with a...

Hello, Have a strange one, we had a gas engineer visit our flat yesterday and since then the boiler fan/pump seems to be always running. Our electricity useage has also increased massively, smart meter showing about 40p by the time we wake up in the morning when usually it would be about that...

Hi I am about to order a new oil combi boiler and installation, and I am confused over what size boiler. I got three quotes, two of which quoted in person and said two different sizes. One suggested 18/25 and the other a 26/35. Putting aside the cost difference of the boiler, the engineer...

Hello, when I bought my house this boiler was already installed, I’m guessing a new boiler is a must, but as we are selling very soon, i do not want the expense of a new boiler. I can see where it is leaking, I believe this is what’s blowing the fuse. So all help would be appreciated as I do...

Hi, my heating which uses a Vaillant ecotec plus 418 boiler installed on an open vented central heating system using S plan has stopped working. The problem is the boiler is not firing up. The boiler status shows S30, which means there is no external demand for heat. I checked the SL to the...

I’m renovating my whole house, making structural changes etc and want to remove all radiators. However, I want to keep hot water running. I have a relatively new Vailant combi boiler. If I remove all rads and cap temporarily, the re-pressurise the system, will that do? Or does there need to be a...

Please can someone help me I’ve lived in this property for a week and yesterday I ran out of gas, I topped it back up and since can’t get my heating back on I am trying to re pressure it but I don’t think I am turning the right things if anyone can guide me in the right direction that would be...

Hi Bit of a strange one, and I have contacted a plumber but they won’t be able to come until after Easter which is fine. Just wondered if anyone had experienced similar. We have a Camray 5 boiler, and for the last few months we have had the heating on ‘timed’ and hot water to ‘on’ - constant...

Hi All, recently had the three port valve replaced. It worked fine for 3 weeks, now it is making loud banging noise when central heating is turned on from controller and there is call from heat from central heating thermostat. Please listen to the video in the link. The noise disappears when the...

Hi As you can see on the attached picture a slow leak has developed on this large plastic piece. I am trying to find out is the leak is fixable and if so with what? If the leak cannot be fixed can that whole plastic section be purchased as a replacement part?

Hi there. We have a Vaillant system boiler which has recently had a new expansion vessel and PRV. However, we still have some kind of pressure issue. The pressure remains pretty constant with daily checks and similar usage patterns (typically 1.4 or 1.5 bar) for about 4 weeks, but then suddenly...

Hi, I’m investigating lukewarm radiators and intermittent hot water in the house I’ve just moved into. We have a British Gas 330+ boiler. I note in the manual it says the boiler is factory preset to 18kW, but upon entering the diagnostics menu I see the “boiler output” is set to 10kW, and the...

Hi Wonder if anyone can help? I’m having a problem with my combi boiler, the CH keeps cycling on/off on a three minute cycle instead of modulating at the set temperature. It will fire up and ramp up to max fire before dropping back again but then overshoots the set temperature (65degC) and...

So I found this site while googling my problem - I can’t find any videos online that exactly match my boiler and since I know next to nothing about boilers, I don’t want to accidentally make the problem worse. My boiler is flashing a CH pressure of between 0.2-0.4, it’s been gradually getting...

Hello, I’ve been going round in circles on this and could really do with some help! I have a Glowworm Easicom 28 Boiler which connects to a Glowworm thermostat in my hall. I would like to instal a Nest 3 to improve efficiency (and because the controls on the thermostat are very clunky). I think...

Im an electrician trying to connect Hive to my Baxi solo 2PF boiler but the hive diagrams dont match the available terminals and I dont understand enough about boilers to chance guessing at it and frying the mother board. Please help! (Diagrams and boiler terminals attatched)

I have an electric boiler which has started making noises intermittently, which sound like it could be the pump into it. See this video to illustrate the noise it makes (the sound started up at the 17 seconds mark): It seems to do this every few minutes, occasionally very often, other times...
