The Saltfire ST-X4 – new addition to our range of ultra-clean-burning stoves. The result of an extensive development program in our labs.

The smallest of the new ST-X models – the ST-X4 is rated at 4.1kW output, and approx 80% efficiency.

Constructed from a precision-welded thick steel body with cast iron door and thermo-refractory fire brick inner linings.

Many times cleaner than the required standard for “DEFRA” exemption, it can legally be used anywhere in the UK including the strictest of smoke control zones.

Designed with simple, easy to operate user friendly controls.

Designed with a large viewing window for amazing views of the fire. The flame pattern with the advanced “after-burner” system is quite unique.

The ST-X4 is a multi-fuel stove able to efficiently burn wood logs or smokeless coal – the coal ashes will fall through the grate and into the ash can which easily lifts out when full.

Finished in black high temperature paint which we source from the USA and with thermo-ceramic clear glass from the industry-leading “Schott” brand in Germany.

There is an air-wash system to help keep the glass clearer.

The ST-X4 has a 5″(125mm) diameter top and rear flue outlet. Can be used with 5″ diameter flue liner or twinwall flue.
