Good afternoon I'm installing a Hive and was wondering if somebody can verify my wiring for me? I have a Worcester combi boiler with a wireless Honeywell thermostat that's controlling a R6660D receiver unit. Would I be correct in saying both N wires would go to N in the Hive receiver, both L...

I have been quoted for a new plumbing system with 2 option. Worcester and ATAG boiler system. What your thought about these 2 brands? As I have also buy all the bathroom components including shower mixer, taps and ceramic. I know this is very objective in terms of design but what would a good...

What flow rate does DHW turn on? My boiler works fine for CH but I have noticed recently that DHW has been problematic. The HW sometimes does not turn on until the tap is turned fully on and when I back off the flow rate to get hotter water, it turns off again. Usually I can get it so that is...

Hi, I had my Worcester CDi classic serviced last week and was told the electrode kit should be replaced due to a glass safety issue (it can crack and leave open flames). I wondered if anyone could tell me: 1 how long this problem has been known about 2 should the electrode kit always be replaced...

Hey guys, I have an old Worcester 24cdi boiler. It's basically an antique, and I'm currently saving to replace it, but for the most part I must say its served us well. Sunday morning we woke up to a freezing cold flat, I open the boiler cupboard and its flashing on lockout. I reset it and it...

Hi there, I have a 10-15 year old Worcester Combi Junior 24i that kettles only on Central Heating cold start. This winter is the first time it's started doing it. When it kettles, if I turn off the boiler via the thermostat for a few minutes then turn it back on again it runs no problem until...

Hi experts. Well my old heatslave 20-25 has been running fine for ages. I thought how well it was doing just last week but it must have been reading my mind as this week it's decided to present me with some behaviour that I have not come across before. Turn the heating or hot water on and...

Hi all. New to site and searching for answers. I have a Worcester Bosch MT10 combo boiler. It’s 5 yrs old. Usually efficient and quiet. Now, suddenly, it sounds like a machine gun. Loud sporadic clicking and then rumbling around the pipe work. First I switched the boiler off and bled the...

Hi, got a 10yrs old WB greenstar 37cdi. Runs nicely but every few minutes has a loud buzz that fades in then back out, lasts for a few seconds and then fades out. Definitely not the pipe work or snagging. Can happen any time, not just upon fire up or shutting down. Any ideas? Thanks

Hi guys, I have a Worcester 24i boiler which sometimes fails to ignite. I have checked the following - Water pressure is between 1.5 & 2.0 when cold. - On the top, reset switch is not tripped. When It works, it works fine. I think, there is a leakage in the system as I have to top-up the...

I’ve got a WB 24i (not Junior) located in the utility room. Yesterday a shelf support collapsed sending some boxes and cans of paint down and sideways into the side of the combi, and then the floor. No visible damage to case or smells of gas/H2O leaks. Since then the DHW works, the CH does not...

Hi All. Apologies if this is a repeated question - I have tried to find an answer on several forums including this one, but none of the threads quite match the wiring diagram I have. This is my current set up: https://imgur.com/a/4Ao0B1P with the Honeywell BDR91 thermostat. If I had to...

Hello, I have a problem with my Worcester Greenstar 42cdi. It was working fine until yesterday. when I noticed that the hot water would not get hot. upon further investigation, I am even more baffled. The boiler is in the upstairs bathroom. 1. Bathroom sink, (closest to boiler) gives warm...

Hi all, I have a worcester 9/14 cbi boiler and has been working ok up until last week. When I turn on the boiler for heating the light comes on but the boiler doesn't fire up. However when I turn on the hot water the boiler fires up and works fine. The divertor valve is heating up both pipes...

I have a shower running off bath mixer taps (i.e. not an electric shower) and for the last few weeks it has been driving me insane... hot water has been intermittent and water pressure is terrible. Plumbers can't figure out what is causing the problem. What happens is this: when I turn on the...

Hi all I’ve got a receiver fitted on to a the boiler and purchased a hive 2 thermostat and hub 360. The thermostat won’t connect to the receiver even when I reset the receiver so it is flashing Amber. Called hive and they said maybe a compatibility issue with the boiler. Has anyone got a...

My mechanical timer has started losing time, meaning my heating is no longer coming on when I want it. I assume the timer unit is failing and needs replaced (or is it fixable?) and was wondering what my best options are? I'm tempted by something like a Nest to give me more remote control; can...
