Comfortable – With its 24 kW heating capacity and 28 kW domestic water capacity, it provides a comfortable solution for houses with high square meters. Even when two taps are opened in the house, there is no fluctuation in hot water.
Efficient – Class-A heating efficiency according to the ErP regulation. It also has Class-A efficiency in XL flow profile of DHW.
Economical – Thanks to the high heat transfer of the aluminum heat exchanger, as well as low natural gas consumption with a modulation rate up to 1/7; Low electricity consumption is ensured by the use of high efficient pumps.
Quiet – It does not cause disturbance in living areas with its sound level down to 52 dB.
Environmentally friendly – Complies with ErP regulation. Low emission and flue gas temperature values are provided.

ONGAS 600 Series floor type condensing boilers offers a wide range of heating options from 230 kW to 845 kW, with aluminum cast heat exchanger, fiber coated stainless steel burner and high-tech control panel which provides comfort features.

ES Series boilers are cast iron sectioned boilers with atmospheric burner (which is suitable for natural gas and LPG), between the capacities 19,8 - 58,1 kW in five different models (3 to 7 sections).

Cast iron sections are produced with flexible casting technique with EN GJL 200 cast iron alloy, with gives high resistance against corrosion and thermal expansions.

Boilers are equipped with electronical control board with ignition control for centeal heating and DHW. There is also opiton for only thermostat control for heating and Piezo-ignition solution for the areas problematic with electricity.

ONGAS 300/W Series wall hung condensing boilers offers a wide range of heating options from 69 kW to 190 kW, with aluminum cast heat exchanger, fiber coated stainless steel burner and high-tech control panel which provides comfort features.
