How does Warmzilla work?

To ensure that you get the right boiler installed at the best price, Warmzilla provides a free online quote tool for boiler installations on their website. The online journey is quick and simple, consisting of a few easy questions about your property and your central heating requirements.

Warmzilla has received a number of positive reviews for their easy-to-use online quote system. The tool will ask you questions regarding your postcode, boiler fuel type, and the kind of boiler system you currently have installed. It will also enquire about the number of bathtubs and showers you have in your household.

If you have a gas boiler system, the installer can conduct your survey online. However, if you have an LPG or oil boiler system, you will need to ring their advisors for more information.

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.
