boiler

Hi All, Kindly asking for some help. Moved into a new build property that has an Ariston boiler and separate water tank with 2 zones (upstairs and downstairs). Each Zone has its own Thermostat - Danfoss TPOne with only a brown (COM) and a black (NO) wire. The TPOne is battery operated and acts...

Please can someone explain what sort of pipe runs a plumber would have made in this situation in a friend's house as it doesn't appear that it should work. A new system boiler was installed downstairs with internal pump, replacing an old heat only boiler that had a header tank in the loft. The...

Open-vent 4-port boiler was recently changed for a new 2-port model. The diagram shows the connections to the FE tank. The junctions are numbered to make it easy to refer to. Can anyone comment on the layout?

I am trying to repressurise my boiler, this has previously been a routine task but the process I would usually follow isn't working this time. I have attached an image of the pipes and valves. Previously I would need to turn the blue and black valves nearest the loop, but this is not working...

Hoping someone can provide insight on issues as we've had plumbers come out 3/4 times and not being able to diagnose. 10 yr old boiler, Worcester Greenstar 25si , hot water runs fine, when heating turns on it causes a lockout/reset required, after 1-3 times of reset it then works fine. Pressure...

My 20 year old boiler is on its last legs, so am looking at replacing it. However I’m in a 3rd floor flat with a flue which goes out of the wall by a window. The boiler is by the wall so the flue is quite short. (I meant to post a photo but I don’t seem to have one, so I will post one tomorrow...

I have a Worcester Greenstar 4000 with a Worcester Greenstar Mini Magnet Filter. I was trying to clean the filter by first opening up the bottom nut to drain the water out but, this ended up being really tight and I ended snapping the nut in two, with half of the nut still in the filter somewhat...

Can someone tell me if the boiler looks okay?

I moved into a house which is heated by an old floor standing unvented gas boiler. When I light up the boiler, it makes a noise that is making me alarmed. It alternates between gas burning hum and a “blowing” sound, as if it was filling with gas. Is that normal? The control box is a Nova 820...

trying to get rid of an air lock in our boiler after emptying central heating system and looked in the airing cupboard at this setup . the alarming thing I found was going up into loft at the F&E tank expecting to see the cold feed being a 22mm ... but its only (equivalent) of 15mm - I say...

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...
