boiler control

We have a glow worm 30c boiler in our new house. Just trying to add our Hive from our old house to this one. I'm a fire alarm tech for a living so would say I'm fairly competent wiring it in myself. I'm however having trouble getting it to work! Followed the wiring diagram from the manual...

Hi all, just moved into a house and for the first time I have a system boiler instead of a combi: hopefully i'm not missing something obvious! We have a Vaillant ecoTEC plus 637 System Gas boiler with separate hot water cylinder with a separate Honeywell control panel. Being summer, on the...

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...

Are the black valves both supposed to be pointing vertically or horizontally? Also are the rest of the valves in the correct position?

Hi, the clock on my Vaillant ecotech boiler has broken. I've taken it out and can see it is a time switch 130. These seem to be discontinued. Does anyone know if a 150 will work instead? Or is there something newer I should be replacing it with? thanks very much!

I have a Worcester Greenstar 27RI compact boiler downstairs which is connected to a Greenstar Wiring Centre upstairs next to the hot water cylinder. The wiring centre talks to the boiler on an eBus connection. About a month ago I connected a Tado stat to the wiring centre on IZ3 in the wiring...

Hi everyone, We’re new tenants in an apartment that has a Vaillant ecoTEC plus VUW 25/26CS/1-5 boiler responsible for water heating and the central heating system. We’ve noticed that every time the boiler starts heating, there is a loud banging or rattling noise. When this happens, the cover of...

Hi, my boiler has recently started misbehaving.:mad: I can't figure it out, hence posting the symptoms to see if anyone can shed any light! It's a Valliant, located in the kitchen, and it's closed system with a water tank upstairs. Controlled by Hive and about 20 years old, but been serviced...

My boiler in the new house is showing 0.7 bar, which seems a bit low. Although it is still working, I'd like to increase the pressure back to the normal range. How can I do this? I remember that the Worcester boiler in my old house had to be adjusted using a special key. Thanks for any advice.

Hi Wonder if anyone can help? I’m having a problem with my combi boiler, the CH keeps cycling on/off on a three minute cycle instead of modulating at the set temperature. It will fire up and ramp up to max fire before dropping back again but then overshoots the set temperature (65degC) and...

Hi guys. I fitted a Hive for my mum as far as im aware my wiring is correct but we cant get the stat and receiver to pair. Paired the L N E from the boiler to the receiver. Then i i linked L in receiver to terminal marked “1”. Then i brought room stat cable to terminal marked “3” on...

Hi I own a Glow-worm 45/60 B boiler but my analogue timer (EMP2) is no longer functioning. I'm curious if there's a way to manually activate my central heating and hot water without relying on the timer. I understand the timer has a continuous option however it seems to be malfunctioning and...

Hi, I just moved into a house which has Vokera Compact HE boiler with mechanical clock timer on it which is super inconvenient and therefore would like to change to smart thermostat. My current boiler (Page 35 for wiring diagram)...

Hi, Have a Valliant EcoTec plus 637 system boiler that is showing no error codes and S.0 (no demand for heat), but it is not heating. Have checked that it is receiving switched 240V heat demand into PCB, so believe it's a boiler issue. Boiler was working fine up until needing to fix small...

My heating engineer is going to install a new combi boiler for me (Ideal Logic 2 Max), which I think he will fit with a standard thermostat / control. This boiler seems to support OpenTherm, and I'm wondering about fitting a smart thermostat and radiator valves at a later date to improve...

I’m looking to change a Honeywell T45 to a Honeywell T6R HW. Y plan system boiler with existing thermostat in the hallway and control box next to the boiler. Can anyone tell me which wires go where and which ones will become obsolete when I take out the old rotating thermostat from the hallway...

Hi sorry if this has been asked before but does anyone know if its safe to use the de-aeration function of my boiler a few times to temporarily heat my system. I'm waiting on a second technician visit tomorrow as one who visited didn't have experience with Myson thermostats. My boiler works...
