How to choose a Heat recovery unit?

Air heat recovery units are essential elements in modern HVAC systems, providing efficient heat recovery and improved indoor air quality. Decentralised air heat recovery units are designed for individual rooms or zones, offering a cost-effective solution for installation and use. Choosing the right recuperator can significantly improve the comfort and energy efficiency of your home. Here is a guide to help you make an informed decision.

Factors to consider when choosing a Heat recovery unit

1. Room size and airflow requirements

  • The size of the room and the required airflow rate are essential to determine the right unit. Measure the room volume and take into account the recommended air exchange rate.
  • Tip: For optimum performance, select a unit that can handle the maximum airflow requirements of your space.

2. Efficiency and heat recovery capacity

  • Pay attention to the efficiency rating of the unit and the percentage of heat recovery efficiency. Higher efficiency means better performance and energy savings.
  • Tip: A heat recovery efficiency rating above 70% is considered good, and for some high performance appliances it can be above 90%.

3. Noise level

  • Noise levels can affect comfort, especially in bedrooms or living areas. Check the decibel (dB) rating of the HRU.
  • Tip: rooms with noise levels below 30 dB are considered quiet.

 4. Installation and maintenance

  • Evaluate how easy and simple the installation is and what the maintenance requirements are. There are some installations that you can install yourself, and others that are better left to professionals.
  • Tip: Look for equipment with user-friendly features such as washable filters and easily accessible components for routine maintenance.

5. Control functions and smart integration

  • Advanced control functions and smart home integration can improve the ease of use of your HRU. Look for units with programmable settings, remote control options and compatibility with smart home systems.
  • Tip: Models with humidity sensors and automatic control settings offer added convenience and efficiency.

6. Budget and energy savings

  • Find your comfortable balance between the initial cost of the appliance and the long-term cost and energy savings. Investing in a higher efficiency appliance can yield significant savings on heating and electricity costs over time.
  • Tip: Calculate the payback period of the equipment by comparing the heating and electricity savings with the initial cost.

Conclusion

Choosing the right Heat Recovery Unit involves considering various aspects to ensure that you choose the right unit for your needs. By weighing up the above factors, you will be able to make a well-informed decision to improve your quality of life and energy efficiency.
