boiler

Quick question, out of the two boilers below, what would you say is the better and more reliable one? 1) Vaillant ecoTEC plus 940 Boiler 2) Viessman Vitodens 111-W Boiler 3) Or how about the Vaillant EcoTEC Pro 24 which is not a storage combi, but has the "aquaCOMFORT System" which is...

Hi, Looking for some advice, an installer came to give me a quote for solar panels and he brought up the subject of a heat pump too. I live in Scotland and apparently the grants only apply if you get both together, which is fine as my boiler is getting old anyway. He said something about the...

Hi all. Does anyone know if there are any combi boiler that can heat both the hot water and the radiators at the same time? I know most don't, but was wondering if there was any exceptions? I can't see why this would not be physically possible as you could have a diverter valve in the boiler...

Ho, I'm looking to replace my valiant ecotec plus 831 boiler which I believe is 25.5kw. I live in a detached bungalow with 8 large double radiators, a single bathroom with boiler fed shower and bath. Bath currently takes a good 20/25 mins to fill. Pipe runs are quite long and the hot taps can...

Hi, When I turn on the hot water function of my gas combi boiler (Glowworm Ultracom2 35Store), I get a leak from the 6 Bar PRV attached to the cold water pipes beneath the boiler. I've had this situation for several months now, and it eventually appeared to progress to also leaking when the hot...

Hi, A British Gas engineer just came round as our boiler is leaking (plastic inside has corroded apparently) - its a worcester bosch greenstar. He told us that he was isolating the electric to make it safe given the leak - the electrics turned off while he was here but I did not realise they...

Some advice would be appreciated here. I want to turn off these valves on the flow/return pipes under my Vokera Mynute i20 boiler to isolate the boiler and hopefully drain it without draining the full system, but how do you turn these? There’s a screw but can’t turn valve with a screwdriver and...

I'm house-sitting for a friend who's away for extended time, but we're in frequent contact. We're trying to determine whether or not his slab-heat residential boiler system has a leak (approx. 1,800 square ft). He recently had the zones drained (they were nearly or completely pure water) and...

I have inherited a very old Ideal Mexico super 2 system boiler (looks like 20 years or more) when I moved into my current 1960s built 3 bed semi detached bungalow property in London South west, couple of years ago. It’s working fine but I’m looking to replace it mainly due to some side extension...

Hello, We're in the process of getting an insulated outbuilding built at the end of our garden for ourselves and also a family member whom has sensory need to use the odd occasion. The new outbuilding will have 3 multi-use rooms which are: 1. A relaxing/sensory room 2. Wet room (Basic...

Having a combi boiler replaced soon, received 3 quotes: First 2 quotes recommended Worcester Bosch (yet mentioned they repair a lot of Worcester's - doesn't give me much confidence). Felt like they may be getting more profit from the Worcesters, I don't know. Last quote recommended Baxi. All...

Hi everyone, I'm hoping someone here can shed some light on a frustrating issue I'm having with my brand new Glow-Worm Compact LPG combi boiler. I had it installed in my small bungalow about two months ago, and for the first month, it worked like a charm. However, for the past month or so, I've...

hey! I need abit of help understanding a problem with my boiler, I brought a Viessman Vitodens 2021 050-W boiler in 2021 and after every boiler service I need to call out Viessman under warranty due to a banging noise when using the hot water tap, the longer the time goes between the warranty...

Hello everyone, My CH works fine, but my DHW doesn't. DHW only works when CH is on too. I've gone through and checked my boiler out. The two microswitches work as expected. The pressure is hovering within the correct range. Both the lights to CH and DHW light up when expected. However, the...

We have a leak and ripped up the floor.. Found a bit of pipe that looks like this (image attached) The boiler was loosing pressure quickly about 0.5 bar of pressure every 15 mins. Since this bit of pipe was fixed the pressure is holding for longer but still dropping, much slower (about 0.5...

I've moved into a house with very basic central heating controls (one of those timer dials from the 80s) and non traditional piping set up which is causing some complications and I want to do the minimum work at the minute to modernise it. The way they've piped up the house the boiler sits...

Hi guys, So yesterday morning I woke up to a f75 error code on my 2006 vaillant boiler ecotec pro 28. After some research I decided to replace the water pressure sensor as the cheapest place to start. So in doing so, I isolated and drained the boiler, fitting new sensors, repressurised the...

Hi All! My first post here.. I need some help from someone who really understands central heating systems, pipes and radiators. New boiler installed My 20 year old Ideal Mini boiler finally failed in December with no hot water and it was leaking all over the floor. It turned out it would be...

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.

While the central heating, water is trickling out of the bottom end of the rear black tube in photo, where it connects with the metal section. There is corrosion at other connections. The PCB has been changed a few years ago and there was also another issue with it losing pressure. It's about 12...
