The advantages of air heating compared to gas heating are as follows:
Air heat pump
1, air heat pump is more efficient
Air-source heat pump heating: energy-saving and efficient, a power can produce three parts of the heat production, the heat pump can be set between 45-50 degrees of high efficiency water temperature can be used directly in the The temperature of the efficient water from the heat pump can be set between 45-50 degrees and can be used directly for floor heating. The average energy efficiency of the whole heating season is about 300%, and the highest can reach more than 400%.
Natural gas heating: 85% (theoretically, the combustion value of the wall-hung boiler can reach more than 95%, but in practice, it is difficult to exceed 80%), while the gas wall-hung boiler high-efficiency water temperature of 70-80 degrees, you need to pass the mixing of water to be used for floor heating.
2, air heating costs are lower
Air-source heat pump heating: lower ambient temperatures in Taiyuan, Shanxi Province, measured as an example (the lower the temperature, the greater the consumption of electricity): the lowest temperature in winter -15 ° C, the unit building, the indoor temperature is maintained at 22 ° C. 100 square meters of the heating area in the 150 days of power consumption of 2720 kWh, according to the residential electricity 0.6 yuan / degree calculation, the cost is 1632 yuan. Calculated monthly running costs of only 326.4 yuan, savings of nearly 90%. Also, many places have a ladder price of electricity, electricity at night instead of cheaper, such as Beijing's heating electricity price of only 0.1 yuan, so the running cost is far lower than the gas wall-hung boiler.
Gas heating: According to each 100 square meters of residential buildings, wall-hung boilers heating 700m?/month average gas consumption, then, the country's many places in the highest level of the ladder gas prices are in the 4 yuan / m?or so. Then the cost of 100 square meters of use is about 2,800 yuan per month. Even according to the pre-ladder gas price level of 2.4 yuan / m? level, the monthly cost of 1,680 yuan. One more thing, the wall-hung boiler due to scaling, energy efficiency decay is very strong, every year is lower, the cost increases year by year.
3, air heating longer life
Air source heat pump heating: theoretically, the core spare parts design life can reach 15 years.
Gas heating: theoretically can reach 10 years, but in the actual use of the process, due to its high water temperature, coupled with the hard water in most areas of the country, the furnace, especially the bottom of the easy to scale, so the actual life of most of the not more than 7 years.
4, air heating machine use conditions wider
Air source heat pump heating: can provide a stable 220v or 360v voltage building can be used. Users with low voltage should be able to thicken the power supply line, or use inverter units.
Gas wall-hung boiler heating: theoretically, there are gas buildings can be used, but in fact, the winter gas heating is a luxury consumption, and is not the state explicitly guaranteed the basic use of gas for residents, so many places face the embarrassment of having a stove and no gas available.
5, air energy heat pump heating security is higher
Air source heat pump heating: the use of electric power drive, as long as to ensure that the machine can be reliably grounded.
Gas wall-hung boiler heating: you must ensure that the gas is fully combusted, otherwise it is easy to cause safety accidents.
6, air can heat pump heating equipment more environmentally friendly
Air-source heat pump heating: heat pumps installed in the outdoor, electricity-driven, is a clean source of energy, today's market heat pumps are mostly used in the R410 environmentally friendly refrigerant, there is no destruction of the ozone, in the use of any emissions, especially in the wind power, hydroelectricity, nuclear power to vigorously replace the coal-fired Today, more environmental protection and energy saving.
Gas wall-hung boiler heating: combustion exhaust emissions in situ, producing toxic gases and exacerbating PM2.5 emissions, polluting the environment and causing haze.
7, air heating is more reliable
Air-source heat pump heating: only related to the supply voltage, as long as the voltage is stable, the stability of the air-source heat pump system and air conditioning stability as well as the same, withstand the test. And now also more frequency machine, the reliability and adaptability of the unit is stronger.
Gas wall-hung boiler heating: reliability is affected by the pressure of the gas supply, the use of insufficient gas in the place affected.
The above are some of the advantages of air-source heat pump heating compared with gas heating, air-source heat pumps need to consider the winter heating capacity attenuation factor to ensure that the heating effect in winter, the capacity attenuation factor can usually be obtained from the air energy heat pump manufacturers. Wall-hung boilers can be repeatedly ignited hundreds of times a day, and the use of fixed-frequency compressors, due to the compressor protection can not be frequently start and stop, air energy heat pump in winter also need to frost, so set a buffer tank can effectively protect the compressor, enhance system comfort and stability.
