Which Worcester Bosch boiler is best for an Edinburgh tenement?

Most two-bedroom tenements suit the Greenstar 4000. One-bedroom flats can use the Greenstar 1000. Larger flats with two bathrooms may suit the Greenstar 8000 Style. The flue route and hot-water demand matter as much as the bedroom count.

What is the difference between the 1000, 4000 and 8000?

The 1000 is the entry-level combi with a 5-year guarantee. The 4000 adds a better display, more output options and up to a 10-year guarantee. The 8000 Style has a black glass finish, touch controls, higher output and up to a 12-year guarantee.

Is the guarantee with Worcester Bosch or with you?

The manufacturer guarantee is with Worcester Bosch. We register it and explain the conditions. Our workmanship is also covered separately — ask for the written terms before booking.

Do Worcester Bosch boilers need an annual service?

Yes, to maintain the guarantee and keep the boiler running efficiently. We remind you when the service is due and can carry it out.
