This is the manual for most Worcester Bosch Greenstar CDi Compact Boilers. You can have a look at this if you have a Worcester Bosch Boiler and have lost your manual. This is free to look at and refer to.
Hi,
I have lifetime experience (50+ years) in United States with basic knowledge of split phase 120/240 volts replacing wall switches and sockets.
We moved to the UK two years ago (wife was born here) and I am aware of the 240 volt system that's used throughout the UK.
I let a flat and with...
Anyone tell me where to connect the two wires that switch the boiler on via the programmer and the 2 wires that call for heat on the ufh control board. Boiler is a grant vortex pro 21 external oil combi condensing. Many thanks.
Hi,
I'd like to move the existing socket that feeds the boiler down to where I've pencilled in that can be seen on the photo. The socket to the left isn't doing anything so I was thinking of blanking this off. The reason for moving the socket is I'm building a larder cupboard around the boiler...
At the moment it depends on the weather on how well the central heating works, the main problem is the Nest Gen 3 thermostat only measures the temperature in the hall, and it turns off boiler some times when living room not warm enough, but can't move Nest into living room, as one there is also...
So I’ve been having this issue with my boiler for a while now, I’ve currently got one stat in the hall that when I turn it on it brings the heating on. Very basic, it’s low voltage switching. See when I turn the heating off it takes ages to go off, it’ll heat the radiators up to absolutely...
Hi.
As per header. I just want to make sure I do this correctly.
Remove old wires from X9 7 and 8 and link these two (from another thread on here. Is this correct?)
X2: remove link between 1 and 4.
Hive neutral to 5,
Hive live to 4,
Hive 3 (live switch) to X2 1
Do I need to link L and 1 on the...
Hi
I'm in a bit of a pickle trying to set up my hot water and central heating systems. Got a gas boiler with a pressure tank and a motor circulating the hot water. There are two wall-mounted time adjustment thingies—one for hot water and heating, and the other for the motor. Oh, and there's a...
Hi folks,
I'd like to get my Nest thermostat up and running with the gas combi boiler (Worcester Greenstar HIghflow 440 Standalone). FYI - I have tried to get this installed by a professional, but I've been let down 3 times now. 5 of 6 quote requests on the Nest website didn't even bother...
Good evening,
I have recently moved into a new home and I am having problems with the MCB/RCD tripping (Mem M6 Type 3 - 30mA). It intermittently trips when I switch on the Central Heating on and sometimes after running the heating for a couple of hours. The heating is gravity fed, hot water...
Had a new unvented Boiler fitted as the old one had reached the end of it's life. Electrician mentioned that it might be worth replacing my fuse box and giving it a separate RCD. My fuse box appears to have 10 black switches and the 3 red main ones, was last checked by an electrician in 2020...
I generally consider myself pretty up on heating systems but this has me slightly stumped… An otherwise very simple system boiler on what I assume is an bog standard S plan. What could make it call for DHW (tank stat registering cold after a full draw) OUTSIDE of the programmed hours and...
Hi,
I'm having a new boiler fitted in a new location. I need to provide power for the boiler which I'm looking to do myself.
Boiler: Ideal Logic Max 35KW Combi
I've researched the electric supply requirements from the manufacture (image below)
My consumer unit has a spare Contactum 7106B 6A...
As a young man, I was an electrician, but now I'm getting on, I am strictly DIY.
I used to have a cheap old 900W petrol generator connected to a dedicated twin socket which I used to run my gas central heating boiler (plus essential TV) in the event of a power failure. It worked fine, but...
Do you install new heating systems? Ever had a missing cable run between a boiler and a pump?
Using MAINSLINK - the pump overrun solution - you can avoid expensive cable runs when cables are missing between a boiler and a pump. When the MAINSLINK by the boiler has 230Vac live input, this...
Just looking at my boiler wiring out of interest, and just wondering if it's wired correctly.
So perma lives, neutrals and earths in the right place, but i can't figure out the switch lives to the controller.
If i follow the circuit it seems like the earth of the 4 core is acting as some sort...
The new Advance Combi Boiler has a feed from consumer unit using 6mm cable on a 32amp breaker to a 45amp double pole switch. What size cable to the boiler should it be from this switch. It has a fused 3amp supply to the electronics section.
Hi - first-time post from a complete novice.
I want to install a 24kw electric boiler on my property but that size requires Phase 3 supply. Northern Powergrid don't install Phase 3 in my area (off grid) but can increase capacity via a split supply. Can I run a phase 3 boiler from a split...
(Or that might be should a failed HW valve keep boiler running)
Woke up this morning to find the boiler still running even though all timers off (HW and CH). We have a simple S-plan CH/HW system with oil-fired boiler and a 2-port zone valve for CH and a 2-port zone valve for HW. Various...
