The CastTec Solid Fuel Integra (SFI) is a range of beautiful cast-iron inserts that integrate with one of the most efficient 5kW output stoves on the market today.

The SFI inset stove has a multi-fuel grate which allows the burning of seasoned wood or smokeless fuels, achieving outputs of 5kW as well as efficiencies approaching 80% with the most minimal of carbon emissions.

Our new generation Polaris inset stove fulfils all the benefits of the SFI inset stove, but has an increased efficiency, a convector chamber (producing additional heat exiting from below the canopy), a wider screen for viewing, a new riddling grate and has the option of a removable handle, making it safer to open the stove door before the stove has cooled down.

All Integra cast-iron inserts, mantelpieces and hearths shown are interchangeable, allowing you to design your own fireplace; it is advisable when using solid fuels to use only natural materials for the mantelpieces and hearths.

In addition, hearths (whether boxed and lipped or Munro) should be cut into sections to allow for expansion.

Solid Fuel Integra can be used in smoke controlled areas (DEFRA exempt) and attains European Efficiency and Emission Requirements to the highest level to achieve ′EcoDesign 2022´.
