As the country pays more and more attention to new energy sources, the new generation of heating and heating equipment air energy heat pumps are becoming more and more familiar. In recent years, heat pump equipment has been rapidly popularized in various places, and has quickly gained a group of “fans”. However, because the equipment is relatively new, some friends don’t know much about the specific use and maintenance details of the heat pump.

Recently, some netizens reported that their own air source heat pump has been used for a long time and found that it is not as hot as before. What is going on? The editor sorted out the four major reasons why the air source heat pump does not heat up the water.

1. Insufficient heat pump refrigerant

Refrigerant is what we commonly call refrigerant, and it is a key substance for heating air-source water heaters. To complete heating, an air-energy water heater must use a refrigerant as an intermediate medium to continuously absorb heat from the air. However, if the air source heat pump is used for a long time, there may be refrigerant leakage. Once the amount of refrigerant is reduced, it will naturally cause the heating capacity of the equipment to decrease, which will lead to a significant drop in the temperature of hot water. The solution is very simple, contact the after-sales personnel to replenish the refrigerant.

2. Excessive scale accumulation

Since the various components of the air source heat pump are in a hot water environment for a long time, it is easy to accumulate scale. The scale contains various complex components, and its thermal conductivity is not high. If it accumulates in a large amount in the hot water system, it will occupy the space that originally belonged to the hot water. In this way, the heating effect of the air source heat pump is significantly attenuated. The solution is to contact technical personnel to clean the air source heat pump equipment regularly.

3. Equipment installation work is not done well

Air energy heat pumps, as the name suggests, need to absorb heat from the air to generate heat. Therefore, although it does not need to consume coal and natural gas, it also requires more attention in the installation location. Under normal circumstances, it is recommended that the air source heat pump be installed in a location with good air circulation, such as a balcony, an outdoor air-conditioning position, an outdoor platform, and so on. These locations not only have strong air circulation but also have a suitable air temperature, which is more conducive to the heat absorption and heating of the air source heat pump.

4. Excessive dirt on evaporator fins

Since dirt may accumulate inside the water system, the same is true for the evaporator fins of air-source water heaters that are in direct contact with the outside world. The air source water heater needs to contact the air through the evaporator fins to absorb the heat energy in the air. Generally speaking, the larger the contact area between the evaporator fins and the air, the better the overall heating effect of the equipment. However, in the long-term working process, dust, hair, and other substances in the air may cover the fins and affect the heating of the air energy. So how should we clean it? It’s very simple, turn off the water heater, spray the corresponding cleaning agent on the evaporator fins, wipe it from top to bottom with a rag, and finally rinse it with clean water.
