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...

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?

Hi, This is my radiator in my bathroom. I want to change it to a towel rail. As a chippy I’ve done fair bit of plumbing but want advice on changing this. What would be the best pipe lay out? It’s a 500 rad getting changed to a 500 towel rail. I know the tails come underneath. Could I put a...

I have an issue with my Salus thermostat (model ST620RF). All of the sudden, the lights on the receiver have gone blue and red (dimmed) and the heating and hot water stopped working. The thermostat has new batteries and is working fine as well. I have tried multiple times to re pair it and reset...

Hi, My heating is switched ON. 3x of my radiators TVR valves are OFF. BUT the radiators are still coming ON. I’ve checked the TVR valve and they are working, the pin is opening and closing they are ok. It seems really odd that this problem started at once, any idea what this could be...

Hi, Could anyone tell me if it is ok to up the size of pipe from my radiators from 8mm to 15mm? My current configuration is 22mm from the boiler then it downsize closer to the radiators to 8mm. I would like to upsize from the 8mm to 15mm but in my head i dont think its possible. Might be...

Hi, I recently had my bathroom renovated (including installation of a new towel rail) and ever since a radiator in one of our bedrooms has stopped getting hot. The only way we seem to be able to wake it up is by turning the overall heating up REALLY high. Any idea what it might be? It has...

Hello. So I’ve recently moved into a 1900’s terraced house with a loft conversion from 2001. The shower in the loft is either scorching hot or Luke warm. It also had problems with being jammed stuck until I loosened it with WD40. However, as it’s the loft, it’s not a priority (I imagine a...

As in the title - What's the required insulation under building regs for heating pipes in the unheated loft space within a residential building? I can't seem to find any clear-cut answers.

I spotted this dark stain on my wood floor around 3 weeks ago, last time the underfloor heating was on was in December. Yesterday I switched it on again and it seems to be getting bigger. The stain is dark, no cupping or crowning, no sign of water or moisture. Any ideas whether it's a chemical...

Hi there , I have an ideal logic plus 24 combi , the pressure dropped and boiler cut out. I set pressure to 1 bar which was same as it has always been. All seemed fine till I turned on hot taps and saw that although it’s coming out hot it’s much slower than it’s ever been Any help would be...

Hi, Summary: I am looking to buy a replacement battery. Does anyone know where or how to find one? I believe this is the problem. I changed the tank to a thermal store. I left the Horstmann switched off at the mains ie no power to charge the battery, for several years. Apparently they won't...

Hi there When I switched on my hot water at the controls today, I noticed that I couldn't hear the 'normal' noises it would make once it comes on and the hot water cylinder isn't getting hot. I have tested the central heating and it works fine. I have a plumber doing work on renovation at...
