hot water cylinder

Hi, My hot water isnt working, and the issue appears to be electrical as the display for my programmer says it is not recieving power. I have replaced the fused spurs and that has not resolved the issue. I took the face plate off of the switch and noticed this black cable is not connected. Is...

Hi everyone, wondering if I can get some advice We have purchased and moved into a one bed flat which had a combi boiler and central heating system installed in 2014. For some reason though, we have an airing cupboard in which there is a massive cold and hot water tank. We think the water...

Hi, I have a Worcester Bosch Greenstar 35CDi combi boiler running on LPG. This works very well providing both hot water and central heating. I have recently installed a PV solar/battery system and expect to have more electrical power than I need for about 8 months of the year. I am looking at...

Hello all, been a frequent visitor here for lots of tips over the years, but this is my first question. I would like to upgrade my Drayton digistat 3 (central heating) and separate Drayton LP711 (hot water) controllers to a single Nest system that controls both CH+HW. System is open vented...

I moved into a flat in May this year, can't figure out the heating and hot water system. I've tried the FAQ's and searching but can't find anyone posting a question in exactly the same scenario. The letting agent has been useless. The flat has a Dimplex RXPW4 pilot wire controller in the...

Hi, I've moved into a new build, built by CALA Homes. Overall, the house is great, but I'm not so sure about the heating system. Outside there's a Daikin air-source heat pump. In the garage there's a gas boiler. Upstairs there's a hot water storage tank. Concern 1: The heat pump only heats...

Hi, I've been quoted for a job from a plumber and he's quoting me for a Main direct unvented hot water cylinder. Does anyone know if this brand is any good? The name makes it very hard to search for it online as it keeps returning results for "mains".

Today we had a visit from a BG engineer and his notes say replaced PRV in boiler. I assume this is a "pressure release valve" Anyway since he left when my hot water timer comes on to heat the tank its like a loud gurgling noise next to the 3 way valve in the cupboard upstrairs. Now when we...

I'm considering a loft conversion in my house as as part of adding an extension. However right in the dead centre of the most useful space, are the two tanks for cold water and central heating. If I have an open vented setup, what is the least I can do to convert to mains pressure and remove...

I previously posted that I thought I was getting water hammer when the header tank in the loft was being filled. I suggested I replaced the float in the tank but the problem did not go away. A plumber suggested that I install a shock arrestor which I did to the pipe which feeds the tank...

I'm renovating an 1880s semi-terraced 5BR house. Much of it is still original, with some rooms lacking power outlets. One thing which has been "updated" has been the installation of radiators, and a combi-boiler (located in a back stairwell on the ground floor, see photo). However, there are...

In a conventional system, the standard arrangement is to have a gate valve on the (typically 28mm) cold feed pipe from cistern to cylinder. Out of curiosity, I was wondering why you won't find it on the hw pipe (typically 22mm) going out of the cylinder instead. Of course, positioned after the...

We have a hot water cylinder with two immersion heater, one standard, one booster. We are with SSE on the Total Heating Total Control system which switchers the main immersion heater on at various times during the day. We had a power cut last Friday and since then the water has been cold and...

Hi there, I am doing a full renovation on a mid-terrace 3-bed house (inc loft) and single-story rear extension. It will have 1 family bathroom with bath, and 1 ensuite and 9 to 12 rads (inc heated towel rails. Electric underfloor heating in family bathroom and ensuite. I was going to put in a...

Hello - always been impressed with this forum, and the time has come for a first post... I have inherited a partially complete hot water system. Currently a 3kW immersion heater heats the water in the (direct) hot water water cylinder. We find the supply inadequate for the family (cold showers...

Hi, I have a Worcester Bosch 35cdi System boiler with optional diverter valve (diverter valve enables it to be used with a hot water cylinder). The control package is via Tado and integrates via the Worcester EMS bus system. My issue is that when the system is heating the hot water tank, it...

Hi All, Hoping someone might be able to solve this conundrum. I have a hot water cylinder with a boiler. I recently drained the system and washed out the radiators. I have no hot water and no heating. The boiler fires up, the 2x two port valves turn the valve to their open position. The...

Hey Guys. I have economy 7 in my Flat - Which seems to work out very expensive (When i have 3 storage heaters on it is around £6 / £8 a day!). I have 3 Storage Heaters (Lounge, Hallway, Bedroom 1). There are also Panel Heaters in the Lounge, bedroom 2 and 3. The hot water comes from a...

Blocked water supply in house by mistake, then got it back, followed suggested routine, start from highest outlet down, supply restored but since then f&e tank overflows, ever so slightly, occasionally the overflow stops but during 24 hrs about 3-4 buckets collect. Get conflicting advice from...
