plumbing and heating

Afternoon, Any advice/guidance would be appreciated. We are completing renovating & extending an old property which will include a full re-plumb & rewire. At current property uses a solid fuel burner to heat water (ancient) and wiring has enough C1's & C2's to justify ripping everything out and...

This question has been posted 1000 times and probably with as many different answers, but I screwed up today so I'd like some input please. I'm a home diyer. I've installed kitchens, tiled floors, fixed cars, fitted taps, replaced thermostats and loads of other jobs but I've never had to do a...

I'm hoping someone can help me get my head around understanding radiator valve pressure drop. As an example, from the attached chart, a lower pressure drop results in a lower achievable flow rate. To my mind, a lower pressure drop (i.e. less resistance to flow) should give a higher flow rate...

Hi all I've got a worcester 28si ii combi boiler with the old standard timer. I've gone out and bought a salus st620rf thermostat with wireless controller. I am wondering if anyone has an idea on how to wire this up and what wires need bridging. Thanks.

I’ve attempted to bung our conventional heating system to change some upstairs bedroom radiator valves and respective radiators. I’ve noticed when I bung the system the bathroom and kitchen taps appear to drain off if I open them, however the radiator pipes appear to constantly flow with water...

Hi, Our hallway radiator burst on Christmas Eve - it’s the second time it’s had a leak so I reckon, as it’s from the 70’s, it’s time for a new one. I’ve fitted radiators before and done bits of plumbing so I reckon I can do it. The wife wants a smaller radiator but a double so we get the same...

Hello, we have a radiator in our living room and would like to add a second. The photo shows the piping going into and coming out of the radiator. From feeling the order that the pipes heat up I think I’ve figured out the direction of flow which I’ve marked with red arrows. Would this pipe...

Hi I am trying to help a friend out with a Boiler Issue. We don't know the model number of the Boiler however I have attached images. There is hot water but the heating has not worked since May and multiple engineers have not been able to resolve the issue. If anyone has any ideas no matter how...

This will most likely be a stupid question, how does this fitting work? Do I literally just thread it on my pipe? What kind of connection is this called? Thanks

I'm planning on relocating the pipes for radiators 1 & 2 to make way for a steel beam. Radiators 1 & 2 will branch off the main flow and return between radiators 3 & 4. I noticed the flow & return leave the boiler in 22mm copper and steps down to 15mm copper before the first radiator, this then...

Hi Everyone, I have a question with regards to a specific requirement I have for an electric 3 way diverter 28mm valve on an ASHP installation? As far as I know most 3 way valves are configured so the flow comes into the bottom of the 3 way valve (Inlet: C) and then the water either flows out...

Hi, I have recently moved house and I want to screw in a large set of bookcases into my bedroom wall. The problem is that through the wall is the bathroom and I am worried about hitting any pipes. I dont have any family members to ask for advice and so I thought I would ask here to make sure. As...

Hi Looking for advice. Customer has a back platinum combi 28he and they have one floor with 5 rads and top floor with 6 and the last couple of rads on the top floor don't get hot enough. I've balanced them and got the last rads on the pipe run Luke warm. Wondering if I could fit a secondary...

I’m struggling to choose my system boiler and controls, between all of the different brands, smart thermostats and technologies, I’m confused. Physical set up is as follows: System boiler and 210l Indirect unvented gledhill hot water cylinder 12 radiators across 3 bedrooms and one bathroom, 3...

Hi, I have an installed a new radiator on a one pipe system, It is directly above the bypass and doesn’t have any bends. The inlet side pipe is red hot yet the outlet is approx 30% cooler. The radiator also feel cooler on the outlet side. I have checked for air and the pressure is 2 bar. lock...

Customer has a gas boiler. Shower only gives out lukewarm water. All taps give out hot water. Have replaced the thermostatic mixer valve previously & the shower then worked perfectly. however over a period of weeks to months it gradually dropped in temperature back to where it is now with it...

Hi everyone, About a month or two ago we noticed that the F and E was overflowing quite a bit. We also had some rusty coloured water. I can see now from research that this would naturally point to a hole in the coil. I had a plumber out, who I wouldn’t use again because he seemed completely...

Adding a vertical rad into our new extension. I noticed the pipes were centered in the wall which I didn’t like so I asked the plumber could we move the rad closer to the corner. Does anyone know of this affects the efficiency of the rad? We were told by moving it closer it would reduce the...

Hi all I am just wondering which setup do plumbers/heating engineers like the best out of these 2 systems with CH header tanks in the Loft? - and is one better than the other or do they both work as good as each other , any caveats with either? *Diagrams not - no-where near - drawn to scale...

Trying to connect Vado Capsule kit to overflow. The issue is when I am trying to install either of the 2 waste adapters it came with to my existing McAlpine overflow they don't fit. Has anyone installed one of these and has the same issue?
