Looking for some advice on rectifying someone’s heating system. The system was working but when it stopped working the sparkie who came to fix it messed about with loads of the wiring now it’s not working great. I’m going to look at it to try & get it going correctly tomorrow so just want to be prepared. From what I gather there’s an outside boiler that is heated when the HW is turned on at the programmer, when the boiler heats the water to temperature this in turn closes a stat which then pumps the HW? Does that sound about correct? There is also another pump & stat which I’m assuming is for the heating? There is also a wood burner which is to be wired so that when switches on will override boiler when boiler is off. I kind of get the general gist of it but not completely sure how to wire it so it works correctly. Any help would be much appreciated. The worst thing is I done one similar as this for the first time a couple of years back but can’t for the life of me remember how
I wired it.
I wired it.
