Do heat pumps lose efficiency with age?

Air source heat pump is one of the most advanced products in the world today. Its working time is generally ten hours. Long-term operation will shorten the life of social security, and at the same time, components are easily worn out, reducing the efficiency of the unit. The air source heat pump unit is stopped and started by the controller, and the working time is too long because the shutdown parameters set by the system are not reached.

 

long-running consequences

  • The long-term operation of the air source heat pump may easily cause the aging of electrical components, short-circuit conditions, or burn the compressor, which will affect the service life of the unit. It has been proved by practice that the long-running units are often 30% shorter than those operating within a reasonable range, and the failure rate is about twice as high. Under a reasonable time of operation, the life of the unit is often as high as 15 years or more, and the failure rate is low.

 

To set a reasonable temperature

  • The startup and shutdown of the air source heat pump is realized by the set temperature of the unit. When the unit has not reached the set temperature, the unit will be in the startup state. When the unit reaches the set temperature, the unit will be in the shutdown state. We can see that the start and stop of the unit is directly related to the set temperature. When we use the unit, we should set the temperature reasonably according to the user's requirements.

 

The reason why the unit runs for a long time

  • 1: The unit selection is too small. Due to the unreasonable selection, the model selection is too small. In the process of users needing heat, the unit cannot provide enough heat, causing the unit to run for a long time, or in order to ensure the profit point of the project, reduce the price of the air source heat pump, etc. In addition, in order to reduce the initial investment cost of the user, the unit selection is too small, so that the heat generation of the unit cannot meet the requirements of the user's heat consumption, and the unit runs for a long time.
  • 2: Environmental climate reasons. The air source heat pump generates heat by absorbing the heat in the air, so as the ambient temperature decreases, the heat generation also decreases. During the selection process, the winter operation of the unit was not considered. The unit operates at a lower temperature, and the heat absorbed in the air is reduced, and the heat obtained by the unit in a single cycle is reduced. In order to achieve the same heating capacity, the unit will work longer, so it is recommended that the normal design working time in the selection process is generally between 10 and 15 hours.
  • 3: The project installation is unreasonable. This is also the reason why the air source heat pump runs for a long time. For example, during the installation process, the corresponding measures for ventilation of the unit were not done well, or the exposed hot water pipes passed through corresponding insulation measures, so that heat was lost invisibly.

 

The air source heat pump realizes cooling in summer and heating in winter, which not only meets the needs of users, but also reduces the use of energy and environmental pollution, which is in line with the needs of today's social development.

Do heat pumps lose efficiency with age?

In addition to being environmentally friendly and efficient, the air-to-energy heat pump has another big feature—long service life.

However, the energy efficiency of the heat pump will get worse and worse with the use of time.

Here are 5 Tips reasons why you should consider replacing your heat pump:

 

Heat pump is 10 years old or more

  • As heat pumps age, they naturally lose some efficiency. So the heat pump you installed ten years ago is not as efficient as when you installed it. While well-maintained heat pumps can last for decades, newer models are much more efficient.

Your heat pump needs more and more repairs

  • When you start needing repairs to your heat pump a few times a year, you can have major problems with your system. At some point, it breaks completely and you need to replace it. Replacing it ahead of time helps reduce the amount of time you can use it without cooling and heating.

As your heat pump ages, it loses some efficiency

  • You'll notice it's an ever-increasing electricity bill. Inspections and adjustments can help, but at some point replacement is the best answer to reducing energy costs

Uneven cooling and heating in your home

  • If you have some rooms cold and others hot, your heat pump may be struggling to keep up

Your home has humidity problems

  • Heat pumps naturally remove moisture from the air. When you start having noticeable humidity problems, your heat pump isn't working properly.
