What is the difference between a boiler and a heat pump?




Both air source heat pumps and boilers are commonly used heating equipment, but they are different in terms of investment cost, energy saving, operating principle, structure, electricity requirements and functions. We have sorted out the advantages and disadvantages of air source heat pumps and boilers, so that everyone can understand and purchase more intuitively.


First of all, there is a big difference in investment costs. Electric boilers are cheaper than air source heat pumps. However, when generating the same amount of heat, electric boilers require three times more electricity than air source heat pumps. Energy-saving air source heat pump saves about 3-4 times than traditional electric heating. It absorbs heat in the air and generates heat through the compressor, while the electric boiler is a device that directly generates heat without any conversion. Since the electric boiler heating process only generates 90% of the heat, the energy-saving air source heat pump is more efficient than the electric boiler. The air source heat pump can perform the process of converting 1 kW to 4 kW throughout the year, while the boiler can only process 1 kW to Power of 0.95 kW or lower.






The structure of the air source heat pump is relatively complex, mainly composed of four main components: a compressor, a condenser, an evaporator, and an expansion valve. The structure of the boiler is relatively simple, mainly composed of a high-power heating wire and an insulating shell. From a safety point of view, during the heating process of the air source heat pump, there is no large pressure generated, and there is no risk of leakage. During the heating process of the electric boiler, there may be the possibility of leakage or the risk of electric shock.






From the perspective of the functional difference between the two, the air source heat pump is an air-conditioning device. During use, it can perform heating and cooling functions according to the needs of users, and can also provide daily domestic hot water, which can be said to have a three-in-one function; Electric boilers are unique and can only perform heating functions. In order to heat water with the same parameters to the same temperature, the heating speed of the boiler is much faster than that of the air source heat pump. Therefore, in some emergency situations, the emergency capability of the boiler is stronger. .




Due to the limitation of investment cost, some users must choose suitable heating products according to their own economic conditions. Because the safety factor of electric boilers is relatively low, you must choose a big brand and a company with good after-sales service when buying. Of course, it is best to choose some well-known domestic brands when choosing an air source heat pump to avoid higher prices and poor quality. And other issues.


If family conditions permit, it is undoubtedly a better choice to purchase air source heat pumps. Air source heat pumps are only higher in cost than boilers. However, in the later use process, air source heat pumps are safe and energy-saving as boilers. Incomparable. After all, if you have a long-term vision and think more, you can make your life more comfortable and convenient in the future.
