The Pell-Duo+ model boilers are intended for water open system central heating installations with both gravitational and forced water circulation. The installation must be secured according to currently valid and detailed national provisions. Steel Pell-Duo+ model boilers with automatic fuel supply system are intended for work in central heating installations and domestic hot water preparation installations in housing development buildings, i.e. single family houses, commercial pavilions, garages, and utility buildings. Pell-Duo+ models are compact pellet boilers with automated kindling and extinguishing. They have been equipped with self-cleaning burner made from heat-resistant steel. In vertical exchanger was used an innovative solution, namely a clean-out ash compartment that insulates the boiler’s bottom, which significantly improves the heating efficiency of boilers. The boiler’s controller is a device made from highly advanced technology adapted to handling energy-saving electronic pumps. The controller handles CH and DHW pumps, as well as valve actuator. There is a possibility to connect room regulator and SafeIT (control via Internet) module.
