Short description
Greyko combined pellet boilers are three-pass, highly efficient, designed for use with the Greyko RB self-cleaning pellet burner. They are made of 4mm thick steel. The burner can be mounted on the side or front. GREYKO EXPERT 20 combined boilers have a modification – the ability to operate on wood and pellets simultaneously. They can also burn wood, using an additional conversion kit. The kit consists of: grate, air damper, curved plates, large – 2 pcs., thermostat, ring with bolt f6-1 pc., bolt M8x30-8 pcs., nut M8 – 8 pcs.
Greyko RB 20 Star is the only pellet burner that has successfully proven itself in burning pellets of any quality without straw pellets, without having to stop the combustion process for self-cleaning, and without cleaning the hearth. Its innovative combustion head has no analogues on our market and does not allow the retention of slag and other silicates that interfere with combustion. There is a possibility of integrating a WiFi module NRM-W3 into the control module, for connection to a system for remote monitoring and control via the Internet – “Naturela Smarthome”.
