What are boiler stoves?

Boiler stoves are woodburning or multifuel stoves that have the addition of a boiler, which can supply your domestic hot water and run your central heating system. They can also be linked up with a new or existing central heating system, so that multiple sources of heat can supply your heating requirements and therefore reduce your reliance on using gas or oil. Boiler stoves can even be linked with underfloor heating and solar panels. The stove itself will need to be fitted in the same manner as a non-boiler stove i.e. connected to a flue liner.



Boiler stoves generally provide a higher output to the boiler than to the actual stove. Each stove will have its own output rating to the boiler and a separate output rating to the stove, and often an indication of its heating capability e.g. number of radiators it can heat. Always use the nominal output rather than the maximum output when finding the right size stove, as this is the output at which the stove would normally be run.


Types of Boilers

The types of boilers available are:


  • Integral (also referred to as wraparound) boilers that are factory fitted and form part of the stove body.
  • Clip in boilers that are provided as an option with the stove and are fitted as an add-on to the stove on request.


As clip in boilers are removable, they are smaller and so do not have as high an output as integral boilers.



We highly recommend gaining advice on the right size boiler stove for your property and heating requirements from a qualified heating engineer. The stove and flue lining will need to be fitted by a HETAS engineer. If the engineer is registered to install wet appliances, as well as dry, they will also be able to connect the boiler to the water/heating system. If not you will need to use a qualified plumber to complete this part of the installation.
