Understanding the Envirogreen oil boiler before you spend money
Because Firebird has a smaller UK dealer footprint than Grant or Worcester, parts and servicing rely more on the installer maintaining a working relationship with the manufacturer's supply chain. Performance-wise the Envirogreen range covers similar condensing output bands to competing brands, so the deciding factor for most households is confirmed local parts and service support rather than the appliance spec sheet.
