central heating

Hi first time post, and appreciate some of the steps below that have already been taken are not standard procedure but I was wondering if anyone here had an interpretation or advice. Have a 3 storey house with a system boiler, 17 radiators in total fed by microbore pipe, with boiler (Ideal H24)...

Hi all, I've just bought a Drayton Multizone Smart Thermostat and 5 of their smart TRVs and looking for advice on the best way to set things up so had a few questions. Please let me know if you need to know anymore about the house and number of rooms to advise best. The boiler is a Main 30kw...

Hi folks, I’m facing an issue and I’d appreciate your help. I have a conventional (gravity fed) central heating system with a water tank in the loft, a hot water cylinder and a diverter valve in an airing cupboard. My issue concerns my bathroom radiator and when it gets hot. It’s like this...

I have a Potterton Powermax HE 85 boiler, which is about 15 years old. This morning I noticed the boiler was off so I checked the house electrics to make sure there was no trip switch activated - there wasn't. I am insured with Baxi who are visiting next Thursday to repair and do a service...

Hi All, Just hoping someone might have an idea on this. The boiler is running fine in terms of hot water but stopped running the Central Heating when called for from the Hive (It's sending a Live feed to the boiler from the Hive so thats all good.) We thought it might have been a PCB problem so...

Have recently moved into a new house and the radiator in our master bedroom clicks like hell when heating up and cooling down. Searched on here and tried everything below but nothings worked. I’ve traced the sound as best as I can, and whilst I can hear/feel it mostly from the TRV pipe side it’s...

I have a twist & lock 22mm Speedfit-type connector (though I think it's a generic brand) on the central heating system and it has sprung a small leak so wish to replace it with similar. I would grateful for comments on my plans to carry out the replacement. The gas central heating system is...

The furthest radiator from my boiler is a 160cm x 50cm Type 22 in my living room. It has always been set as the bypass, but this isn't ideal. The living room can overheat, whilst the kitchen is cold. The obvious answer would be to set a lower temperature on the TRV in the living room, but this...

Hi all, I moved into a new house earlier this year, so this is the first winter. The house is approx 25 years old and has the original (system) boiler with HW cylinder (serviced each year). When we first moved in we had plenty of HW. However, since winter has come along and we have had the...

Hi All, Need help please. I noticed the radiators upstairs were not getting hot and the top of the towel rail in the bathroom was cold. I bled the air out of all the radiators checking downstairs too and refilling water using the filling loop as i went. I got to having 1 bar system pressure...

Hi I live in a rental and only two of my radiators have TRV heads. There are valves with no heads I am hoping someone will recognise what they are and I can just buy a head and not a whole new valve If anyone can help that would be amazing

Hello! I have a new Vaillant boiler being installed and will install a new cylinder at the same time. Our installer is recommending a UK Cylinders ProLite Air twin coil solar indirect unvented cylinder 300ltr. According to specs the standing heat loss is 1.80 kWh/24h which seems pretty decent...

Hi all, I moved in to a new house earlier this summer which I believe has a system boiler (I'm used to a regular boiler in my old house). The HW is programmed to come on twice a day. This week (as I am sure a lot of people have :)) , the CH went on for the first time. I noticed that when the...

Hi All, Thank you for your time! FTB's - We're moving into a new property in 2-3 months time which currently has an old-style gas multipoint water heater and electric storage heaters, but no central heating. The property is a 1950-1960s end-of-terrace three bedroom, would there be any...

Hi About 2 months ago we had a neat fitted and UFH with its own thermostat. The CH did work when it was first installed but with it being summer it was left unused. Now the Nest does not appear to be firing up the boiler. The green dot is on the heat link which means they're connected. The UFH...

Last autumn, I cleaned out the central heating system (old back boiler with F&E) with X400, and dosed with X100. It hadn't been touched for a good few years prior to that. A few months later, I find this gunge in the tank (stringy/white stuff) which Google tells me is probably bacterial and...

Hi All, I am doing a kitchen extension. 3m X 6m, and like to install wet ufh. need help to decide the best way to prepare my concrete subfloor for wet ufh. option 1: mot + sand blinding + dpm + kingspan + dpm+ concrete + ufh boards (18mm) + ufh pipes + screed + tiles option 2: mot + sand...

Hi Householder here. Non-expert. Central heating circulation. One of my (total three) radiators doesn't get hot. It is full of water (no air). There is a regular lockshield value at one end and a TRV at the other. They are both open. I have checked the spindle in the TRV (FAQ6). The...

Hello, We recently took down a radiator temporarily for paintwork. (We have an Ideal Logic System boiler with hot and cold water tanks in the flat, if useful to know). We re-fixed the radiator this morning but now have no hot water or central heating. We have an F1 error message - all water...

I have just dismantled my old oil boiler (22 yrs old) and electrics that go along with it. A new one will be installed later in the year, and moved to a different location due to building works. In doing so, there are a couple of components in the electrics that I have no idea what they are...
