combi boiler

I had plumbing work done in bathroom. My boiler now keeps turning on for 25 seconds, i can hear it doing something like pumping air or gas or something out, and then stops for 8min and then repeats. is this normal and I'm just noticing it now and hadn't before? everything switched off in the...

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...

Discovered, on getting an engineer in to fix what I'd thought was probably a minor fault preventing the boiler from working, that it has had to be condemned (and yes, justifiably - you should see the insides! Ye gods ...). The house (probably 1000-odd sq. ft.) is a fairly typical 3-bed layout...

Hi, I have a Chafoteaux Maury Britony combi se 80 ... Yes I know :( ... it came free of charge with the slightly delapidated flat I recently bought and worked fine for the first 3 months. The heating is working fine but the hot water is now luke warm at best and only fires up the boiler when the...

Hi all, I’m looking to replace my current thermostats with Hive. I have ESI ESRTP4+ thermostats in the bedroom and hallway of my flat. With a Logic ESP1 35 combi boiler. When looking at the wiring needed my current thermostats only have 2 wires. NO/ON and COM. Hive obviously needs more...

I have ideal logic combi 30. I have put the hot water setting to maximum heat and reduced the water pressure to very low but I am still getting luke warm water. Central heating is working fine. some one told me that it could be heat exchanger plate. I don't know much about these. any help would...

Hello, we are planning a rear extension which will add an new UFH system, one extra radiator, and an extra towel rail. Currently we have a 10 year old Worcester Bosch 25si combi boiler which is doing alright. It has recently been serviced and the gas engineer said it is looking good...

Evening all, I'm looking to have my 50 year old conventional boiler replaced with a combi, and may have a HWC added in a new location at a much later date. The current boiler is a Potterton Netaheat Electric 16/22. The teeth on the knob on the front have gone so the actual setting is somewhere...

Switching from an ESI ESRTP4RF+ to a Drayton Wiser with a Worcester Combi boiler (single zone/one channel) The current wall plate wiring looks identical to the Drayton Wiser scheme, but just wanted to check if it would be plug n play. Attached photos of current wiring on wall plate. I...

I need to connect a drayton wiser controller to a boiler Potterton Gold Combi 24 HE A. Can you please advise on the wiring scheme? Please see the wiring picture of the Potterton Gold Combi 24 HE A

Hi, I have an unusual question. When I switch on my hot tap, am I right in assuming that the hot water will be delivered solely to my hot tap? even though the path of the hot water may pass through multiple tee’s on the way (which will have cooled water at their other connections). I expect the...

Last year I had a new combi boiler installed alongside the Drayton Wiser smart hub system. This is the boiler: Ideal Logic Combi Boiler This is the controller system: Drayton Wiser Kit 1 I didn't know at the the time that the installer could wire it NOT using the OpenTherm module. I want to...

The furthest radiator from my boiler is a 160cm x 50cm Type 22 in my living room. It has always been set as the bypass, but this isn't ideal. The living room can overheat, whilst the kitchen is cold. The obvious answer would be to set a lower temperature on the TRV in the living room, but this...

I'm currently in the process of insulating my garage (cold roof). I'll be using a Moll Intello vapour control membrane after the insulation and before battens and plasterboard. The boiler is currently located on the brick wall and as such can't be wrapped (sealed) with the membrane. Is it...

Thought I'd clean out magnaclean filter on my combo boiler (intergas rapid+ 32Kw) Was a complete new install 3 years ago. The system had inhibitor and from what I remember a biocide for the UFH. There was hardly any crud on the magnet, but the grey strainer was slightly green stained bit like...

Hi All, I've got a Worcester Bosch Greenstar 30Si combi boiler and I'm trying to replace the room thermostat which has a faulty display. The faulty thermostat is a DT10RF optimiser which is discontinued so I purchased a Comfort 2 RF which is supposed to be the equivalent replacement. It...

Hi, I've recently moved into a new home, which has a combi boiler (my first one) and it's a Worcester 532/i. Everything is working correctly, in that I can make the heating come on if I need it, and there's hot water in the taps. The problem is, it's always making a noise even when the heating...

Hi, I've got a combi boiler. I was thinking of turning down the temperature of the heating on the boiler (i.e. on the boiler itself not the temperature on the thermostat). Reading up on this it sounds like setting this as low as possible is the best option in terms of reducing gas usage - to try...

I have an old Worcester Bosch Greenstart HE plus combi boiler. 3 months ago the shower, which has been working perfectly for last 5 years, would start off at correct temperature and then after about 2 minutes would run cold. Just as it was running cold I heard the boiler fire up and after...

So I just had the heating system drained by a plumber to replace a UFH mixer valve, he filled it back up and left in a hurry. I ran the heating to see if it worked OK and noticed all the radiators upstairs were only half full. I turned the heating off and bled them. I tried running the heating...
