Coal boiler STALMARK PID - 20 kW with exhaust gases temperature sensor
Stalmark PID boiler is equipped with a newest microprocessor regulator which is steering the power of the boiler. The regulator is controlling the temperature of the exhaust outlet (keeping them on a constant level) and keeping the constant temperature of the boiler.
The controller except standard sensors is also equipped with the exhaust outlet sensor. Thanks to that, the temperature of fumes are always at the same level. The controller is constantly measuring the temperature of fumes at the outlet. In case of significant rise of temperature at the outlet of the boiler, the work of the fan is slowed down or stopped.
Using this type of steering with the exhaust outlet sensor, the user can save up to 13% of fuel. In addition, the temperature of the water output is very stable and extends the life of heat exchanger (boiler). The control of the temperature of fumes at the outlet of the boiler causes lower dust and hazardous gases emmission and the heat energy from the fumes is not wasted but used for heating.
Advantages of Stalmark "PID" boiler:
the possibility of combusting every type of solid fuel
quick and easy maintance
controller is using two pumps: central heating pump and domestic hot water pump
large chamber furnace
- 48 months for water tightness of the exchanger, however no longer than 54 months from the production date
- 24 months for electric and mechanical devices (controller, ventilator)
- 12 months for flue gas temperature sensor and the furnace door protection
