Aqua-Stoke Models #SB200

DS is a family owned business that was established in 1978. DS has over 30 years of experience with designing and manufacturing solid fuel stoves and boilers. In 2015 DS started the research and development of the Aqua-Stoke. It is an auger fed stoker with a pot burner, designed to burn rice coal.
