One small F&E tank - around 18" x 12" x 12" - ish, mounted high up above the boiler
And one big cold water tank for the house - wouldn't even like to guess the size without going up there to measure (oval shaped; 5'x4' perhaps)
Both fed with ballcock vales
thanks
I've flushed through today...
Hi, think we have a flow rate problem in our central heating....but don't know how to tackle it..
We've an old CH system, which was installed before we moved in 16 years ago...and to be honest not well serviced, but has never let us down. BAXI boiler and expansion tank in loft, that feed a pump...
