Hi Terry,
I'm pretty sure it's mains fed (is that the right phrase) and it's been at least 5 years since i can say for certain that it has been topped up.
It needed it last winter - the upstairs radiators and towel rail were only half hot
Hi folks,
I've just spent a solidly unfruitful hour and more trying to locate how to add pressure to my Worcester Heatslave 18/25 boiler
(my radiators haven't been bled in a while, so i'm figuring i'll need to add pressure to the system once i'm done)
Having found nothing but the least...
