Sharp Screen Wall mounted gas boiler

Detailed Product Description

Wall mounted gas boiler

Closed type strcture,precise,economic and easy use.The disigned life is higher than 15 years.

The electronic components and major parts are made by top level suppliers from Germany,U.S.A and ltaly.

Control circuit board:the control core on the operation of highly intelligent devices and safely protection.

Many types of built-in energy-saving protection programs:Quick starting on sanitary hot water system;Short time circulation control;Time delay control on circulating pump.

Compatible with all general characteristics of Euro type boilers;The digital display screen realizes man-machine conversation;intelligent operation.

Closed combustion chamber:The blower drains out the exhaust gas and absorbs the fresh air from outside.The combustion chamber and room of house are separated completely,safely guaranteed.

Fuel gas ratio regulation:Adopting SIT gas valve and ignition control;realizing proportional control.The temperature of the heating system and the sanitary hot water is very stable,creating a comfortable living environment.

Water pressure protection:When the heating system pressure is higher than 3 bar,the pressure will be relieved by the relief value.When the water pressure is too low.the heating system may display failure code.

Operation in low water pressure:The start-up flow of sanitary hot water is 3.5L/min.Even in the region or floors with very low water pressure,the hot water flow is still stable.

Failure indication:When the machine is out of order,the temperature is lower than 8,the pump of the wall-mounted boiler starts automatically.If the temperature is lower than 5 in continuous mode,the wall-mounted boiler starts automatically to prevent freezing of boiler and heating system.

Air pressure protection:When the fume duct is blocked or the down draft occurs,the flame is extinguished automatically.When the blockage is removed or the air force are normal,the machine works automatically.

Power off and gas off protection:The machine stops working automatically when the power or the gas  off.The machine can not work automatically after the gas supply comes back,The machine can be started manually only to normal operating mode.

Anti water pump seizing device:When wall-mouted boiler stops the service for 24 hours,the water pump works for extra 2 minutes to prevent seizing of water pump.

Extra circulatory function of water pump:When wall-mounted boiler stops the service,the water pump works for extra 1 minutes before stopping to prevent overheat of the water pump and heat exchanging devices.

Extra exhausting function of water pump:When wall mounted boiler stops the service ,the blower works for extra 20 seconds before stopping to drain off the reside exhaust gas inside the wall hanging boiler.
