Latest Warmzilla Back Boiler to Combi Boiler Prices
Warmzilla’s expert engineers can replace your back boiler with a more energy-efficient and compact combi boiler from premium brands such as Worcester Bosch, Ideal and Vaillant.
Warmzilla can replace your back boiler with a combi boiler of up to 40kW, depending on the needs of your property. Please note, back boiler replacements tend to be more expensive than standard like-for-like boiler swaps, as the process requires the removal of the back boiler and for the new combi boiler system to be installed in a different location. Getting a back boiler removed will typically add around £140 to £1,010 to your installation costs.
Nevertheless, Warmzilla can provide you with an excellent deal. For example, the replacement of a back boiler with a Worcester Bosch 4000 30kW is £1,146 cheaper with Warmzilla than Boiler Central.
Another bargain offer from Warmzilla is their installation of a Worcester Bosch 8000 Style 40kW with only a back boiler removal premium of £140 over a combi-to-combi swap.
