View Full Version : Boiler Timer

01-12-2006, 11:00 AM
Hi Guys,

Complete n00b when it comes to DIY and the such so please bear with me... ROAR!!!

*cough* Anyway, I have just moved in with my missus and in the house she says the central heating / hot water combi boiler seems to have a broken timer unit. This means that I have to manually switch the unit on and off which is becoming a pain in the bottom! (and expensive when we forget to switch it off)

I can still set the thermostat to adjust the temperatures but it's either on.. or off.

I'll get some more information about the boiler etc and do a full investigation at the weekend, just so I can get it clear in my head what is going on.

Can anyone help / advise? what I should be looking for / how to test etc.

Thanks so much in advance.

I thougt my timer was broke when I moved into my new house and only found out after a year that it wasnt, I used to leave the heating on full 24 hours and could have saved a fortune.

Mabey your not as stupid as me but I would make sure it was broke first as it was a woman who told me that it didnt work in the first place.

hi there

you can use any external timer, and check your boiler manual for more info.

I have a combi boiler & fitted an external timer / combined thermostat. Just set the boiler to be always on & the thermostat turns it on & off when required (I had an analog one on the boiler & wanted more control). Was about 40 in B&Q.
