The boiler is over 20 years old so we have decided ourselves to have a new one. It does have a 3 way valve. All rads have individual thermostats on them. The timer control is in the utility room for the on/off times. Hope these replies answer your questions.
How do I found out what boiler size I need? Had differing quotes from plumbers and now at a loss. House is 5 beds - 1 bathroom - 1 ensuite. I have 14 rads in the house. Current boiler is Combi floor mounted Worcester Heatslave High Flow. I have been told Worcester is the best so want another one...
When the heating went off I continued to hear the \\\'humming\\\' as if it is on. After a while I checked the rads and found 3 rads upstairs stayed on even though the heating isnt. If i turned down each thermostat to below the 3 mark they went off. I have a worcester combi boiler. Can anyone...
