i have just bought an old farm house, an had to remove the rads to allow the walls to be plastered. thus draining the system. i,v fitted all the rads back again but cant fill the system back up. there is a water cylinder in the batroom upstairs with a water tank above it. there is also feed tank in the attic & a boiler down stairs in the kitchen & a separate water tank in the loft this tank when switched on gives hot water to the ensuite only. at the moment i have no hot water anywhere else in the house & no heating.
this is the first time i'v seen a system like this & desparetly need help. could any1 tell me what type of system this is? & how to remedy this problem. thanks
