HWAM 4660C

An impressive Defra approved woodburner that delivers everything that you could possibly want from a contemporary stove with a medium-sized heat output.

The Hwam 4660's large physical presence (it's 1388mm high) and stunning good looks, with choice of five different stone coverings, will create a wonderful focal point in any living space. It also scores top marks for performance and practicality. It has a DIBt tested 100% room seal as well as optional direct external air supply capability making it the perfect heating solution for a large living space in a low energy home, especially one with MVHR.
The optional stone covers (all 71kg of them for the Soapstone option) and concealed heat storage stones (a further 45kg) provide gentle heat release for hours after the fire has gone out to maintain a comfortable ambient room temperature for hours. Hwam's Autopilot combustion air control system is standard and can be upgraded to the full SmartControl management for a little extra which not only maximises efficient burning but can also save you up to 50% on fuel usage.
