Heating And Bathing Combi Home Gas / LPG Wall Hung Boiler 20-42Kw

20-42Kw Heating and bathing Combi Home Use Gas/PLG Wall Hung Boiler

The role of the main board: It is used to control the start and stop of the HVAC equipment, and constant temperature of the system.
 
The function of the gas valve is to ensure the normal combustion of the boiler. In a certain range of gas pressure, make the boiler stable combustion and can automatically adjust the gas supply according to the requirements of the boiler heat output, in order to realize the automatic shutdown of the boiler and gas proportion regulation.
 
The function of water flow switch: detect the amount of tap water through, under certain conditions, make the boiler switch to domestic hot water mode.
 
The role of the air pressure switch: The air pressure switch is mainly responsible for the safety protection in the wall mounted furnace system. It is divided into two chambers by a valve inside, and the two chambers on both sides of the valve are respectively connected with two pressure measuring tubes. By comparing the pressure obtained by the pressure measuring tube, it can detect whether the smoke exhaust system is normal.
 
The role of water pressure switch: In order to ensure the normal operation of the heating system, the system is filled with water, and maintain a certain pressure. The water shortage protection can be achieved by detecting the system pressure through the water pressure switch.

The system connection and water injection connection are performed in the following steps
1, loosen the pump automatic exhaust valve and the system body heating water distributor or radiator exhaust valve.
2. Open the water refill valve and system water supply valve of gas heating hot water furnace and close the water outlet valve of sanitary hot water.
3. When the pressure of the heating system reaches 0.1MPa (the pressure gauge shows 1.0bar), close the water refill valve of the gas heating hot water furnace.
4, In order to discharge the air in the pump as soon as possible, you can start the circulating water pump repeatedly. There is air in the system , which will cause noise and affect the normal operation of the system. Close the exhaust valve of the water system when it has discharged water.

When the wall mounted furnace starts, after the system pressure is normal, the water pump starts to promote the heating media water flow, turn on the water flow switch or water flow sensor, output water flow signal (switch signal or pulse signal) to the main controller, the main controller receives the water flow signal, start the fan to clean before, and detect whether various safety devices are normal, in the case of normal safety devices, Ignition, and then respectively open the first and second valves, gas into the burner under the action of electric spark ignition gas combustion (in the process of ignition, the fan is generally half speed operation or power by inertia operation, to be burning, according to the amount of gas to determine the fan speed. For the use of gas proportional valve models, proportional valve ignition current, minimum current, maximum current, and respectively can be adjusted), through the ion flame technology to make the flame normal combustion, heating media through the radiator to the air or radiation out, to achieve the purpose of heating. And so on.

The system connection and water injection connection are performed in the following steps

1, loosen the pump automatic exhaust valve and the system body heating water distributor or radiator exhaust valve.

2. Open the water refill valve and system water supply valve of gas heating hot water furnace and close the water outlet valve of sanitary hot water.

3. When the pressure of the heating system reaches 0.1MPa (the pressure gauge shows 1.0bar), close the water refill valve of the gas heating hot water furnace.

4, In order to discharge the air in the pump as soon as possible, you can start the circulating water pump repeatedly. There is air in the system , which will cause noise and affect the normal operation of the system. Close the exhaust valve of the water system when it has discharged water.

The three differences between gas wall mounted furnaces and ordinary household gas water heaters are:

1: Different functions, gas wall hanging furnace heating has perfect heating function. Heating and hot water in winter are not delayed, hot water is provided in summer, and the installation of gas wall hanging furnaces requires a strict process; Gas water heaters can only provide hot water. Gas wall hanging furnace sets two systems and one equipment inside, the use of functions can be independently controlled, the technology used is much higher than the ordinary household gas water heater.

Second: safety factor, the ignition of the gas wall hanging furnace will go through its own 26 or more tests, and the test will not be ignited until there is no safety hazard, and the water and electricity as long as one does not pass will be considered a non-safe environment and will not be ignited. Gas wall hanging furnace needs a long time to work a total of about 8-9 hours a day, the need for accurate temperature control and a number of safety protection measures, it has many safety features gas water heaters do not have, such as multi-point temperature limit detection and control, water and electrical fault safety, IPX electrical protection grade, gas water heater is fired once opened, and there is no detection. The ignition will be activated regardless of the water and gas.

Three: cost energy consumption. Gas wall hanging furnace and ordinary gas water heater are natural gas, but because of the difference in its burner, according to the consumption value of the burner, the burner of the wall hanging furnace is about 10%-20% energy-saving than that of the water heater. Of course, the specific energy saving depends on the brand of different gas wall hanging furnaces.

In general, gas wall hanging furnace is a more advanced home heating equipment, is the current mainstream product of home heating, and domestic natural gas water heater is mainly to provide hot water for life, it does not have the main function of heating is an essential difference between these two products.

The gas wall hanging  hot water heater  can be used for both purposes, while the ordinary household gas water heater generally only provides hot water function. Gas wall mounted stoves have a powerful family central heating function, can meet the heating needs of multi-room, can be connected to a variety of heating systems such as radiator, floor heating and fan coil. You can also decide to turn off the heating in a room separately according to your needs, and the gas wall hanging furnace can also provide the function of domestic hot water. You can use it both ways. The gas water heater supplies hot water for a short time and also uses gas as fuel, and its main function is to provide domestic hot water for families.

The water way of circulating hot water is: circulating water pump → main heat exchanger → hot water inlet at three-way valve → hot water circulation outlet at three-way valve → plate heat exchanger → circulating water pump.
