central heating

Hi all, In these difficult times, we aren’t able to get a plumber to the house, so hoping for a DIY solution. We’ve been having problems with our central heating and hot water recently. No heat from radiators, and the hot water gets lukewarm at very best. I think we have a pumped(or gravity...

Hi, I have created a man cave above my garage, and want to central heat it, so I have fitted all the radiators, and I am now ready to buy a boiler and get a qualified person to fit it. We live in a rural area, and the water supply to the garage is supplied from a natural spring , pressure...

Hi, I’m putting in a new radiator and have been completely flummoxed by the old microbore central heating. The valve union where the radiator tail connects appears to be 1 1/4 inches (although the brass cap I bought from screwfix has 3/4 stamped into it) weird. The new radiator tail has a 1/2...

Hi all, long time reader but first time posting. Firstly thanks for all the good advice on this forum - has helped me out massively over the years!! Have an issue with a radiator - had a failed motorised zone valve which I replaced yesterday and when checking the radiators were subsequently...

Hi, I have a 3bd house, there are 4 radiators upstairs and 4 downstairs. The boiler is a Worchester (I'll update with model later) and the system was disconnected with the house in renovation for over a year. A heating engineer came out and commissioned the system, signed it off and left idle...

Hi, This is my first post ever on the internet. we’ve just moved in to a Victorian detached house. In 12 months we’ve had 3 power flushes done on a very dirty system. A plumber has just left saying we need a power flush as the water is dirty - I am reluctant to part with another £600 when the...

One of my radiators is refusing to heat up. This follows some building work earlier in the year elsewhere in the house - but I don't think this rad would have been impacted by the work. I've confirmed there is no localised trapped air in radiator (rad is fully bled) and I've already attempted...

Hello everyone wanted some advice on our Central heating system in our flat in Berlin we brought 3 years ago...we inherited the system from the previous owners which are... Junkers boiler Ceranorm and thermosta (set to come on 6am-11pm at 21C) Grundfos pump on timer (set to come on three times...

I’m looking to add a rad in a downstairs living room - and by far the easiest route to a flow and return happens to be straight through the ceiling into the upstairs circuit (which has 3 rads on). Connecting it to the downstairs circuit would be a lot more tricky. Could this work or is it a bad...

I have a heat only Worcester Bosch 30kw boiler and a 300L Ideal unvented cylinder. There are 3 zone valves, one for ground floor heating, another for 1st floor/loft heating and the last is for hot water. There is only one return pipe for the radiators. I had this and completely new pipework done...

Can one of the experts out there give me some advice? I am a long term DIYer and thought I had a good grasp of my CH system but...... My Worcester 30 CDi (open system with fill and expansion tank) has begun to short cycle. Fires properly, temperature begins to rise quickly and within about 30...

Hello, I've installed a big column rad with normal valves (no TRV) on a single pipe system, i have done this in 2 other rooms with good success and continue to get very hot. The rest of the house is on a 2 pipe system and works well. When i converted the rest of the house to a 2 pipe system i...

Hey all, I'm relatively new to DIY plumbing. I've found this forum extremely helpful so far and this is my first time posting. I'm having to renew some of the parts on my central system in the airing cupboard. I'm replacing the 3 way valve and motor, the gate valves on the heating pump, and...

Hi all, Looking for some advice. Just bought a house – terrace, 821 sq ft, ground floor has 2 reception rooms, with kitchen and bathroom at back, with 1st floor holding 3 bedrooms. Looking to do a full renovation – ground floor extension (keeping 1st reception room but get rid of the current...

I am adding radiators to my 2-pipe pumped, vented central heating (UK). The whole piping is copper 22mm and microbore, and I'm extending it with 15mm pex barrier pipe graded for central heating. I know that the first bit of pipes connected to the boiler must be copper, which is the case...

Today I drained my CH/HW. This is a standard vented, pumped S plan with two electric valves, and I'm in UK. I was lucky enough to have a drain valve underneath ground floor, relatively accessible, see pics: However, upon refilling the system, I found out that that valve will rotate...

I am trying to get hold of a replacement dual thermostat pocket for my tank but not having much luck. It is a Tribune HE tank made by Kingspan. The threads appear to be slightly tapered at the front. Can anyone suggest where I could get one?

Hi, Currently insulating a ground floor suspended floor, whilst the floor boards are up we've decided to relocate our radiator, but I've discovered the central heating pipes are stainless steel, can go from stainless steel to pvc pipes? If so can any recommend a transition joint. I'm thinking...

Hi, i have bought a property and doing some renovation. I took off upstairs radiator by draining water. When I drain the water pressure gauge at the boiler goes down to 0 as expected but when I turn the mains water it goes up to about 2.5 and stays there. Its an old worcester combi boiler. Is...
