my dad has just had a new boiler fitted from a glowworm swiftflow 40 to a main 18 he . The guy fitted but couldnt wire up as he would have to look into wiring as theres only a switch live on the new boiler and permanent on the old boiler. looked on internet about it and found that a pump overun is built in on the main boiler.
Would wiring have to be changed from box to power boiler with switch live.
Any help is greatly appreciated, dont want him coming back with a story were he can charge more money
