Saltfire ST4 DEFRA 7.5kW Multifuel Stove | Metallic Black Default Title The Saltfire ST4 is the  larger version   of the popular ST2 - a is a great looking  modern design ultra-clean-burning   wood and multi-fuel stove. Designed with simple,  easy to operate user friendly controls . Constructed using a triple-layer convection system, there is a precision engineered welded outer and inner steel body with thermo-refractory fire brick inner linings. 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 ST4 is a  multi-fuel   stove able to burn wood logs and smokeless coal - the coal ashes will fall through the grate and into the ash can which easily lifts out when full - if you want a dedicated wood-burner please see the ST1 or ST3 models which share the same advanced technology but with a wood-burning base inside the firebox. 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 ST4 has a 5\"(125mm) diameter top flue outlet (there is no rear flue exit). Can be used with 5\" diameter flue liner or twinwall flue. The ST4 has a removable baffle plate to allow cleaning access to the flue.   Specifications Product Specifications Services We can offer a full HETAS compliant installation service with this stove for an additional cost.
