Solid Fuel Boiler Burnit NWB Prime

Description: The BURNiT NWB Prime boiler is designed with a fan for forced air circulation.This boiler has intelligent electronic control.It is available in different versions depending on output - from 20 to 110 kW.The boiler is intended for heating medium and large residential or commercial buildings. It offers the option of fitting a gas, oil or pellet burner

ADVANTAGES:

• The electronic control controls combustion by managing the fan operation; it can control up to two pumps – for central heating and for domestic hot water (DHW).
• Forced-draught fan supplying air to the combustion chamber; optimises the combustion process and fuel consumption.
• The water jacket completely surrounds the combustion chamber for maximum use of the heat released.
• The combustion chamber has a large heat exchange surface and low chamber resistance.
• The large and convenient combustion chamber door makes it easy to load solid fuel up to 50 cm.
• The ribbed surface of the combustion chamber and the three-pass flue gas path improve heat exchange.
• The replaceable metal grate protects the combustion chamber from the fire.
• Opening in the lower door for fitting a gas, oil or pellet burner (option).

SAFETY ELEMENTS

• Safety valve
• Safety heat exchanger – in case of overheating, cold water flows through it, lowering the boiler temperature. The boiler must be connected to the water supply network via a thermostatic valve (not included).
• The electronic control controls the fan and the air supply.
• STB – safety thermostat – switches off the fan and stops the combustion
