*****************************************************-

1) The boilers are to have 2 functions – Heating & Hot water supply which work autonomously from one boiler. One mode is to heat the apartments. The other is to supply with hot water for apartments.

Both circulation rings are to be separated and to work in different temperature range.

2)Two heating models to select, they can change each other easily through "Model changer" on the bottom.

    Floor heating: *0~*5°C;

    Radiator: *0~*0°C,

   it is free to set up the temperature.

3)Domestic hot water is prior.  When hot water faucet is opened the gas boiler convert from Heating mode to Domestic hot water mode and modulating gas valve allows to heat water evenly.  Gas boiler continue to heating  water until the source is closed and then The boiler return to Heating mode or standby smoothly.

    Above conversion be controlled automatically by Microcomputer inside boiler.

4) Anti-freeze protection measure.   When the room temperature drop to below 7°C the circulating water pump operate and modulating gas valve allows to warm the water to *0°C then boiler stop working.

     Above operation also be controlled automatically by Microcomputer inside boiler.

5)Pressure release valve.   When the Heating system pressure reach to 3 bar the safety valve will be opened to relief the high pressure automatically.

6)Balanced flue,means Admission pipe inside the Exhaust pip like the concentric circles.

Its advantage is not only discharge the exhaust gas outside but also consume the outdoor fresh air instead of indoor. Moreover the high temp exhaust gas can preheat cold outside air that can increase the boiler heat efficiency.
