Boiler

[StevieTee]

Need some help guys.

I am going to be wiring a combi boiler and this might sound ridiculous, but I've never actually been anywhere near a boiler in my time. So instead of avoiding them challenge, I'm taking it head on...

So as well as the boiler, it's going to be controlled by a control unit ( as in pic below, but it doesn't have the hot water side ) but the simple question is how is this done?

cheers

Combi boilers heat water instantaneously on water flow so there is no need for a signal from a controller.

Single channel time clock required.

It's not got the hot water side. Only the HEATING ADVANCE. That's a picture off the internet. So how is the wiring done? From spur to controller the. To boiler or what?

Make sure that you don't go switching a mains supply onto the boilers pcb or you could find it becomes a very expensive new venture

 

[AndrewMgan1976]

Is your heating being controlled from the timeclock or is there a thermostat too?

 

[StevieTee]

Only a time clock.

Have you read the manufacturers documentation? If not, why not?

I sure one of the lads on here would do the job for you very quickly. For a fee.

Don’t take on work you can’t do, otherwise you make a fool of yourself just as you did before.

The boiler will have live, neutral, earth, live supply to the controls and a switch live back. Imagine the programmer and stat as 2 switches in series. Run a 4 core heat resistant flex from the boiler to the programmer and a triple and earth from the programmer to the stat. At the programmer wire in live and the neutral with stat neutral (if it needs one). The live supply from boiler to terminal 1 the live to the stat in terminal 3 the switch from the stat in a connector or terminal 4 with the switch line to the boiler. Its really simple. If you look at the programmer and stat paperwork you`ll figure it out very quick.

Worcester Bosch do a good book of boiler wiring diagrams

Honestly, don't fret. You'll spend more time making good.

Cheers for the help lads. I got it working, pretty straight forward when you step back and take 2 mins to work it out.
