I have a three bedroom semi, built circa 1975 and need a new boiler. I want
to have a combi boiler and am looking at Worcester Bosch systems. A
Greenstar 24i junior has been suggested. Would this be powerful enough to
heat eight radiators and one bath/shower? The house is fully double glazed
and has some insulation in the loft, although not up to current
recommendations. I have been quoted £1200 to replace the aged Baxi Barcelona
boiler, which would include removal of the cistern etc. Does this seem
reasonable?

Thanks

John
