EKO-KWPR Dual : 15, 25
characteristics
Boilers EKO-KWPR Dual have a dual combustion chamber: one for manual filling of solid fuels, and the other for automatic feeding coal eco-pea. Multi-functional electronic controller supports combustion of fuel in the upper furnace with water grate and the lower furnace retort, provides pump control. Optionally, you can control the boiler via a room thermostat.
Boiler advantages:
- high efficiency,
- economic exploitation,
- mechanical fuel supply,
- automatic operation based on a programmed controller with the ability to connect the hot water sensor (included in the boiler) and room thermostat, mixing valve,
- simple, fast service and maintenance.
- low level emmisions of harmful substances,
- emergency water grate in case of failure screw feeder.
