We had a call from one of our customers who said there is an issue with his Worcester Bosh Greenstar gas boiler. After deeper investigation it was not worth to repair it as cost of the parts and labour would cost almost the price of new boiler. Customer decided to go with our engineer recommendation and we installed new boiler. We normally recommend Vaillant https://www.vaillant.co.uk/homeowners/Boilers and in this occasion Ecotec plus model has been installed.
