    hi im josh , i was wonderingwhat the differences are between a Baxi Combi 80e and a Baxi Combi 80eco ?

    thank you josh

  • Boiler Systems says:

    The differences are small as these are essentially the same boiler. The 80eco is described by the manufacturer as “a value for money combination boiler which is designed for the budget conscious user in mind”.

    The 80e has 10 status indicators, the 80eco has 3. In addition the 80e has concealed user controls, frost protection and 24 hour pump exercise. In addition there are some design differences for the boiler installer.
