Boiler Choice
I have a standard mains gas boiler ..... Baxi Barcelona
Considering changing this, need 30kW heat output ...... an option would
be Worcester Greenstar 30Ri or the 8000Life
Though could just get another Baxi .... 430 or 630 HEAT
Is the Worcester worth 25%+ premium ? ...... I know it is 4% more
efficient
