OMEGA E series steel gas boiler

Product range: 12.5 to 50 kW. Operating pressure up to 3 atm. The advanced system protects the heat exchanger against overheating, draught loss, sooting, and freezing. Operation in a heating system with both forced and natural circulation of the heat transfer medium. Efficient operation with a minimum ratio of the volume of water in the boiler to the heat exchanger weight and area.

Description

Description

Product range: 12.5 to 50 kW.
Operating pressure up to 3 atm.
The advanced system protects the heat exchanger against overheating, draught loss, sooting, and freezing.
Operation in a heating system with both forced and natural circulation of the heat transfer medium.
Efficient operation with a minimum ratio of the volume of water in the boiler to the heat exchanger weight and area.
Continuous and smooth power modulation minimizing energy consumption.
Possibility of connecting the following: an indirect heating tank, a thermostat enabling adjustment of the boiler temperature relative to the indoor temperature, a Modbus remote control device (optional) to monitor and manage the level of comfort in the house (Android and IOS), outdoor temperature sensors, the Lemax Comfort series turbo nozzle for the exhaust gas forced removal, heating, and hot water supply system pumps.
Resistance to changes in voltage (180 - 245 V) and gas pressure (6 - 25 mbar).
Low noise level.
Easy boiler maintenance due to the quick-detachable top panel.
