Im in the process of having some quotes for a new boiler (under the scrappage scheme).
I have had a few guys out and found the one I want to use, but he says the new boiler that he fits (a Vaillant Ecotec 428 Regular Boiler) needs to be directly connected to the pump for the central heating as the pump will turn on up to 60 seconds after the boiler and this is not good for the boiler. The problem with this is that it requires running a cable from the pump (upstairs) to the boiler (downstairs).
My question is, is he just saying this to make a few more quid out of me or is he right?
Also, at the moment my current boiler turns on and the pump turns on about 30 seconds later, what triggers the pump to turn on currently if there isnt already some sort of connection to the boiler alreeady??
Thanks in advance
