hot water cylinder

Hi, I have a Worcester Greenstar 27ri condensing boiler and an Ideal Indirect 210 hot water tank. Basically, I've had a number of issues over the past few months with water passing through the tundish and out via the blow off (when either or both the hot water or heating is on - although...

Hello We are changing from gravity fed to unvented cylinder with other building work. The plan is to ditch the shower pump and move to mixer showers off the unvented cylinder. 4 bed house 2 bathrooms 2 girls, wife and I. Fairly regular 1 adult guest as well. Hot water pressure currently poor to...

I visited my parents house (3 bed semi detached, two showers) the other day and they told me that they paid £300 in utility bills last month. They have a smart meter so I did a quick experiment by turning off the HW cylinder and the daily cost dropped significantly. So I'm thinking that perhaps...

Hi, I have recently had a new hot water cylinder installed and am alarmed at the loud noise its making, its a loud rattling vibration noise that sounds like its going to explode. Has anybody come across this and know the reason?

24 hours ago – our area had no water due to a mains problem. We noticed this first thing in the morning (could’ve happened over the night), with no cold water but hot water still flowing – presumably due to the tank in the loft still having some water. Thankfully Severn Trent fixed the mains –...

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 recently had a leaking immersion heater problem attached to an unvented cylinder. This was going to be my first big plumbing adventure, and I did lots of research on how to replace it. I managed it eventually, but I had some issues draining the tank and wanted to bring it to your attention...

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...

Hi, Wondering if anyone would be able to help me or whether it’s going to be a call out via the landlord… My hot water isn’t working, I live in a flat and we have a water cylinder. We do not have a boiler in our apartment. I have checked the fuse box and everything is switched on. I have...

Hi I have a Y-plan open-vented heating system. The hot water cylinder (in an upstairs cupboard) has 22mm feed and return. When hot water and central heating are both switched on the system seems badly balanced with unrestricted flow through the cylinder in preference to the radiators. To better...

Hi everyone, I'm looking for some advice please... We had a heat pump installed about 10 years ago and with it a Joule twin tank setup. The bottom one is the buffer tank and the top one is an unvented hot water cylinder. However, the hot water cylinder was set up vented. This was working OK...

I’ve had a long term issue with my shower and occasional air locks. It is gravity fed and boosted with a negative head Salamander pump (ESP50). What I’m finding is occasionally the shower is reduced to a dribble and you can hear air pulling through the pump until it automatically stops….if I...

Hi all We have no hot water from our immersion heating system. I have checked the main trip-switch in the fuse box, and fuse on the switch on the wall, both are fine. I suspect that the thermostat itself may have tripped. However I cannot see a reset button on the thermostat. I have attached...

Hi guys Great forum. I have an unvented cylinder which is a Telford Tempest 250 litres with external expansion vessel, which we have the hot water on from 6am - 10pm (gas boiler). But within 2 hours of the hot water going off, the water from the cylinder is stone cold. If I turn off the hot...

Hi all, I need advice. I got a new water cylinder installed in my flat. When I use the mixer shower, very hot water randomly comes out. This issue didn’t happen before I got a new water heater. What could be causing this issue?

Hello and Happy new year and all that. This question involves two disciplines, wood burning stoves and plumbing. I have experience in installing wood burning stoves, but plumbing and associated regs and what’s available I’m not so sure on. So, taking my 6KW wood burner, with 6inch liner i am...

My Mum just complained about a strange smell in her "airing cupboard" and sent me this photo.. I'm stumped... help?!

Hi, I have a flat which has a vented, direct combi hot water tank. There is 2 immersion heaters. One on economy 7 and another that acts as a boost at any time. It is a ground floor flat. I need to replace it as it is leaking and has been for some time. I am trying to decide whether to get a...

I need to boost the pressure for the whole house HW system - low pressure gravity, long pipe runs, slow flow to HW tap in kitchen and utility room. Converting to pressurised system is an expensive option at this stage, so contemplating a whole house booster pump (Salamander RP120 SU or similar)...
