You Should To Know Heat Pump Can Replace Furnaces
What is the difference between a heat pump and a boiler?
Cost of investment
- In the case of the same heat production, the electric furnace is slightly cheaper than the air source heat pump, but the electric power required by it is 3 times larger than that of the air source heat pump.
- Air source heat pump is a process of absorbing heat in the air and producing heat through compressor compression, which saves energy by about 4 times compared to traditional electricity; while electric boiler is a device that directly produces heat, without any conversion in the middle. Therefore, only 90% of the heat can be generated, and the energy-saving air source heat pump is more energy-efficient than electric boilers.
- 1. The air source heat pump can realize the process of converting 1 kW to 4 kW all year round.
- 2. The furnace can only achieve 1 kW to achieve 0.95 kW or lower processes
- 1. The air source heat pump unit is relatively complex, mainly composed of compressor, condenser, evaporator, expansion valve, and four major components.
- 2. The structure of the furnace is relatively simple, mainly composed of high-power electric heating wires and insulating shells
Difference in security
- During the heat generation process of the air source heat pump, there is no pressure and no danger of electric leakage. In the process of heat generation of the electric boiler, the main insulating shell should check whether there is the possibility of electric leakage and the danger of electric shock.
Electrical power requirements
- The electric load required by the air source heat pump is 1/3 smaller than that of the electric boiler, and the requirements for the power grid are smaller than those of the traditional electric boiler.
- The air source heat pump belongs to the air-conditioning equipment. During the use process, it can realize the heating and cooling functions and daily domestic hot water according to the needs of the user, realizing the three-in-one; while the electric boiler is relatively simple and can only realize the heating function. Heating the same parameters of water to the same temperature, the boiler rate is much faster than the air source heat pump, so in some emergency situations, the boiler's emergency capacity is stronger.
- Compared with heating by electric and gas water heaters, it is also mainly reflected in the three characteristics of energy saving, safety and environmental protection. In terms of energy-saving effect, the energy-saving effect of heat pumps in different regions is different. Compared with electric and gas water heaters, the energy-saving effect is as follows: the environment above -15°C can reach 20-30%; the environment above 0°C can reach 50%. -60%; in the environment above 5°C, the energy saving can reach 65-75%; in the environment above 30°C, the energy saving effect is the best, which can reach 80% to 90%.
What are the disadvantages of boilers?
- 1. Emission of harmful gases will pollute the environment.
- 2. If it is too close to the wall, it will generate dangerous heat, which is easy to cause safety hazards.
- 3. Some gas furnaces are noisy during operation.
- 4. It is more troublesome for users to go out for a long time in cold areas to prevent freezing.
- 5. Furnaces need to use a lot of fuel to generate heat
What are the advantages of heat pumps over boilers?
Air source heat pump has a wide range of applications
- The use of gas wall-hung boilers for heating needs to be limited by the supply of gas. During the peak period of gas consumption, there may be insufficient gas consumption, and many regions will continue to carry out gas consumption policies for customers. When the demand for natural gas reaches a certain level When the standard is reached, the air circuit will be terminated and it cannot be used again, which is very troublesome and affects the user's heating experience.
- The air energy heat pump is only related to the working voltage of the power supply system when it is working. If the working voltage is stable, the air energy heat pump can operate smoothly. At this stage, most units use frequency converter technology for central heating, and its energy saving effect is even more obvious. Requires very little power.
Low cost air source heat pump
- The heating cost of a gas wall-hung boiler is about 2,000 yuan a month, and in the case of the same total area and the bent structure of the engineering building, the cost of using an air-energy heat pump for heating is only about one-third of that of using a gas-fired wall-hung boiler. , which is about 700 yuan. When the air-energy heat pump is used for heating, it absorbs the energy in the air, converts it into high-temperature energy through the refrigeration compressor, and then transfers the heat to the water, and then heats the water for heating. In the whole process, only a part of the electromagnetic energy needs to be consumed when the refrigeration compressor is working, and most of the heat is generated from the air. The general energy efficiency level can reach 2.5-3.0, so its heat production efficiency is extremely high, and its operation consumes energy. also lower.
Air source heat pump can be used for two purposes
- The gas wall-hung boiler can only be used for heating in winter, but the air energy heat pump is different, it can be used for two purposes. As long as you choose different heating terminals, you can achieve heating in winter and cooling in summer, which is very convenient and saves money. The working principle of the air-energy heat pump is similar to that of the air conditioner, that is, the heat transfer is realized by using the refrigerant. In winter, it absorbs the low-grade heat energy in the air, compresses it into high-grade heat energy through the compressor, and then uses this heat to heat the water. Finally, the hot water passes through the pipeline and is transported to the ends of the fan coil, air-energy heating, radiator, etc., to generate hot air for indoor heating. In summer, the air source water heater will produce a lot of low-temperature water. As with heating, this low-temperature water can reach the end through pipes, creating cold air that is discharged into the room, and finally reducing the indoor temperature.
- Compared with gas wall-hung boilers, the advantages of air-energy heat pumps are really too many. It can save energy and save money, and it can be used for two purposes. It can be said that it is the most preferred heating product today.
Safety and environmental protection
- Air energy heat pump heating uses air as the heat source, absorbs the low-level heat energy that is not easy to be used in the air during the working process, transmits energy through the internal core components, and uses floor heating and fan coils to dissipate heat, so that the radiator has no worries of high temperature burns, and no more Hazardous gas leakage, combustion and explosion and other safety hazards. Coal-fired boilers often emit a large amount of carbon monoxide, sulfur dioxide and other acidic and corrosive substances during use, which cause harm to the surrounding environment, great harm to the human body, and great danger. Accidents can cause great harm to people.
- Generally, the water system is the main heat source. Whether it is the heating surface or the cooling surface, the body feels more comfortable. The indoor temperature can basically be kept at a constant temperature value. The air heating of the water system adopts the form of water and floor heating. Extending from the soles of the feet to the room is in line with the traditional Chinese medicine concept of keeping the feet warm and cool at the top; in addition, floor heating can also promote the blood circulation of the human body, which has a certain role in enhancing immunity. Coal boiler heating often makes the indoor air extremely dry, making it difficult for people to breathe.
- High-tech applications, such as jet enthalpy increase method, DC frequency conversion method, etc., greatly improve the cold resistance of air energy, so that the low-temperature wind energy heat pump unit can still operate stably in the ultra-low temperature environment of minus 25 ℃, and work above minus 7 ℃ When the wind speed value of the unit can reach above 3.3. Side blowing design, anti-freeze tray, anti-freeze, anti-condensation water low-temperature discharge, intelligent frost technology, make the unit defrost more thoroughly. Under the low temperature condition below -25℃, the air-energy heat pump can still operate stably, meeting the needs of winter heating in northern my country. For specific applications, while effectively protecting the water from freezing, it also makes installation and maintenance easier and more convenient for users.
