cylinder

Please help. I’ve tried everything. My French doors won’t lock. I lift the handle up and the locking bolts of the door appear to drop into place and the handle lifts. I put the key in the barrel and it appears to lock fine. Then when I remove the key I can press down the handle and the door...

Where on a cylinder will I find useful info so I can find a replacement? It has a big circular Hercualg sticker at the back the size of a dinner plate. A Creda Redhead 6146 immersion and not much else. A pipe out the top, pipe in the right bottom side, one out the left bottom side, and one...

Hi all, I've got a problem with my gravity fed hot water cylinder that started last week and I was hoping for some opinions or ways of troubleshooting the issue, as I'm completely stumped now. It does have an insulated foamy thing around it. For 2 years we've had our hot water cylinder warmed up...

Hi there, I was wondering if anyone could kindly help me I am splitting my maisonette up (planning permission granted) the first floor is its own self contained flat and the loft will be its own flat. The loft will have electric hard-wired radiators. I will only require hot water for: shower...

Hi, I have my boiler in my downstairs toilet, and on the top floor (3 storey townhouse) have a hot water cylinder in the airing cupboard. When the boiler is off and pilot light is not ignited there is still a rumbling noise that sounds like it is coming from somewhere in the house in between the...

The outlet pipe on my hot water cylinder is constantly cold to the touch, the water in the tank doesn't last the day. I have bled the pipe and the hot comes through eventually. When bleeding, the outlet pipe becomes hot again but is cold almost as soon as I close it back up. Attached pic with...

Hi, I have a Vaillant system boiler setup with the new (July 2023) ecoTec 630 and a VR71 wiring centre. I asked Vaillant before purchasing this whether there was any benefit of using a Vaillant cylinder over a third party and was told no, they all do the same thing. So I chose a Gledhill hot...

Hi All, Bit of an odd query. We are going through a renovation project that’ll take a few years due to funds and ongoing life, but we need to get hot water sorted asap. We need a temporary stop gap solution for hot water while we wait for our gas connection to be made, approx 3 months for SSEN...

Is it okay to still use a conventional boiler on the hot water setting only to heat the storage tank (cylinder) whilst the central heating has been drained?

Hi, I have two indirect water cylinders (Gledhill) connected to a gas boiler (Vaillant). The system is setup/programmed so that the tanks heat up twice a day for about 2 hours. When the tanks start to heat, one of them makes a loud vibrating noise, sometimes for about 15-20 mins, sometimes for...

Previously had a WB Greenstar R28 HE System boiler with 4 pipes and vented (gravity fed) cylinder. No valves or pumps outside of the boiler. Worked fine for 20 years. Decided to change to Viessmann 050-W System boiler when WB failed but keep the same set up with cylinder. Gas Safe installer I...

Any reason why a combi cylinder has a gap in the insulation between the main section and the header? I can see copper in there, so wondering about filling it with some spare expanding foam.

I'm looking at replacing a direct combination 'Economy 7' hw cylinder. The current in-situ and very weepy and corroded cylinder has no warning/overflow connected, and as its in a cupboard in the middle of a single story flat, there is no way of getting a pipe to the outside. Suggestions please?

I need to install a shower pump I've bought a Stuart Turner Monsoon Single Impeller Positive Head 3.0 Bar and and s flange. My question is, does it have to go on the floor or could I mount it above the hot water cylinder as long as it's more than a meter below the cold water tank? The...

Hello, I’m after a little advice. I’m in the process of renovating a house in which it will eventually have a water cylinder in the loft (no gas in property!) I’m thinking of buying this gledhill 120l direct unvented cylinder, see link...

Hi, Newbie here when it comes to plumbing so apologies if what I'm asking is stupid. I've moved into a new build house which has an indirect vented hot water cylinder, supplied from mains and heated via a boiler. Traditionally I've always been used to combi boilers and when needing to do any...

Hi All, I am in a new property and for last year or so i have been hearing a big bang noise while opening taps (more noticeable) or shower. Once I open a hot tap mixture after lets say 30 seconds or so this loud big bang noise is heard somewhere near the bathroom wall (There is a cylinder...

I'm not sure how to wire a dual cylinder thermostat into this any help would be most appreciated .

As of yesterday none of our radiators have been heating up. However, we still have hot water. We have an old conventional (ie not a combi) Potterton Promax 24/2 HE boiler on a vented system. The thermostat is not the issue since I switched the override on to turn on the CH but the boiler...

Apologies if a new thread is inappropriate for this query, but previous similar threads don't quite cover my question. I've got a RM Cylinders 1200 x 400 unit, with a scavenged immersion heater. I use a Myenergi Eddi solar diverter to send excess energy from my solar panels to the immersion...
