JLG23-B900 is a home heating device used in cold winter.

From 2008 we obtained china goverment's Production Licene of gas-fired production. And we own 7 years stable gas boiler production experience. and our boiler 90% efficience.

1) The boilers have 2 functions

  - Supply Heating for house, apartment. It connect with radiator/floor heating pipe to combine a system to working.

. - Shower Hot Water for washing.

Heating & Shower function work independently and work in different temperature range.

2) 2 Heating Models to choose,

  - they can change each other easily through "Model changer" on the boiler bottom.

    Floor heating: 30~55°C;

    Radiator: 30~80°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.

     Until user close water faucet the boiler will continue to supply heating.

Above action is controlled automatically by the Microcomputer inside boiler.

4) Anti-freeze protection.

 - When the room temperature drop to below 7°C the circulating water pump running and modulating gas valve allows to warm the water up to 30°C then boiler stop working.

     Above acton also be controlled by the Microcomputer inside boiler.

5) Pressure release safety valve.  

 - When the Heating system pressure reach to 3 bar the safety valve will be opened to relief the high pressure automatically.

7) Limiting 92°C temperature protection. ( Dry burned protection)

 - when the temp sensor find boiler inner temperature reach to 92°C, the boiler will be stop heating and alarm.

8) Exhaust by powerful blower.
