combi boiler

Combi Boiler is Worcester Bosch Green star 30i about 5 years old, serviced 12 months ago. I noticed the pressure gauge on boiler was almost completely obscured with condensation. Only noticed yesterday (yesterday) I have been putting the heating constantly through the day on this past week as...

Hi all, Hoping to get some advice on my system. Moved into a second hand house last year, previous owners done the following New pipes flow / returns throughout house along with new hot/cold water feeds. New ideal Logic combi 30 max installed upstairs, 2 floor house. Roughly 9kw of Type 22...

Hello! Wondering if someone can help, Google doesn’t seem to understand my question… I have 2 upstairs radiators (combi boiler) on smart TRV’s which don’t get hot when valves are open. The TRV’s work fine, and I can hear them call for the boiler correctly but the rad’s stay cold. HOWEVER…...

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...

Hi all my boiler is losing pressure. It seems to be only happening when we use the central heating which suggests that its a leaking component in the system. Thing is this has been going on for a year or so ( we tend to use the log burner rather than the ch) so I would have thought if it was a...

I had a Worcester Bosch Greenstar 4000 installed in November 2024. I wanted to increase the hot water temperature above 60 so I can fill my bath more quickly with hot water for my occasional soak in the bath. On the boiler display the maximum hot water temperature is 60 yet on the Comfort + 2...

I’m baffled We run an older Vailant combi on gas. Recently the hot water has begun acting strangely. Kitchen tap gives a good flow of hot water. However the sink and bath taps run hot then soon begin to run tepid. The bathroom is actually closer to the boiler than the kitchen so I’m confused...

Hi, Hoping someone can help. I’m switching my Honeywell Thermostat out for a Hive one. I just wanted to confirm the wiring in the receiver. I have attached a picture of the current wiring and the diagram from hive. Is it as simple as Earth > Earth Neutral > Neutral Live > Live A > 1 Common B >...

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...

I have a Worcester GC2000iW C Combi boiler - it appears to be the model (circa 2019) that is only compatible with Worcester's own Comfort +II RF controller and the EasyControl Key. The Control Unit is pre-installed with the Key. I wanted to know if anyone has had any success circumventing it...

Hello, I have combi boiler Heatline Capriz 2 28c running hot water and radiators on the ground floor. I have underfloor heating system on the top floor with two zones upstairs, using Heatmiser UH4 controller. The underfloor heater currently works when combi boiler timer (or heating switch) is...

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...
