Ninefold Protection 100 Precent Safe

- Frostbite-proof Device: When the temperature of circulating water is lower than 6 oC ,the water pump automatically running. At that time, the combustor runs at the lowest power. When the temperature reaches 20 oC , the combustor stops running.
- Lock-proof function of water pump: Every time the machine stands by for 24 hours,the water pump will automatically run for 1 minute.
- Bypass protection device of water pump: When the main heat supply loop is closed by accident and the waterway circulation stops, the bypass valve automatically open to protect the system and water pump.
- Flow monitoring device of main loop: When the flow of main loop is too low or the circulating water stops by accident, the system will be automatically closed.
- Limiting temperature protection device: When the water temperature reaches limit,the combustion proportional valve will be closed and the system stops running.
- Air pressure protection device: When the fan doesn''''''''''''''''t work, or the flue pipe is blocked,or the air pressure is too high, combustion will automatically stop.
- Heat supply system water pressure protection device: When the pressure of system water is above 3 bar, safety valve will automatically open for reducing the pressure.
- Flame-out protection device: When the combustor quenches by accident,combustion proportional valve will be closed automatically.
- Water temperature sensor protection device: When the temperature sensor of water supply or living hot water appears short circult,or open circult,or the resistance value is abnormal,the sensor can show failure code.

For Wash & Heating In One

- Digital Control: With large scale integrated circuit, system operation is controlled by digital techniques. Heating and living hot water temperature is input digitally, gas quantity is adjusted automatically, so it is energy-saving and safe. Indoor temperature control can be connected.
- Priority on living hot water: The high-efficient composite bushing heat exchanger with unique process improves the reliability of system. Heating water and living water is divided strictly and the temperature can be set freely. Principles of priority on heating water can be guaranteed.
- Constant temperature: It is designed special flow stabilized mount for living hot water system. When the water pressure is in fluctuation to cause flow change, the temperature of output water is constant and it can be effective to prevent the water from being cold at one time and being hot at another time.
- Energy-saving: The combustion chamber adapts import high-efficiency heat insulation Morgan porcelain plate which is energy-saving and the thermal efficiency can reach above 90%; It chooses the intelligent room temperature controller researched by our company, so it can save fuel gas above 10%.
- Safe: With close gas supply and exhaust design, this product gets fresh air for combustion from outdoor, and the waste gas is exhausted outdoor through double-layer with same axis gas supply and exhaust pipe. Such design can ensure safety. Combustion camber is totally isolated from other components, in this way it can effectively prolong the service life of electric component.
- Environment friendly: Negative enhanced combustion technology changes the air flow direction, in this way more air can be combusted and the combustion is complete. The CO content in the waste gas is lower than 0.01% so it is environment friendly.
- Close system: With close waterway design and built-in expansion wafer tank, the circulating hot water is totally isolated from atmospheric air, so it is hard to form scum and if can reduce the corruption of heat supply system.
- Floor heating: Be equipped with special computer chip for floor heating, especially used for floor heating.
