Energy Recovery Unit

Energy Recovery Unit vs. Heat Recovery Unit – What’s the Difference? 

When it comes to optimizing indoor air quality and energy efficiency, both Heat Recovery Units (HRUs) and Energy Recovery Units (ERUs) play a crucial role. But what sets them apart—and why should you consider an ERU?

HRU (Heat Recovery Unit):

- Transfers sensible heat (temperature) between incoming and outgoing air streams

- Doesn’t manage humidity

ERU (Energy Recovery Unit):

- Transfers both sensible heat and latent heat (moisture)

- Maintains indoor humidity balance

- Reduces load on HVAC systems

- Ideal for climates with high humidity or seasonal extremes

Advantages of Energy Recovery Units:

- Better indoor comfort through temperature and humidity control

- Lower energy bills by reducing heating/cooling demand

- Environmentally friendly – less energy, fewer emissions

- Great for commercial buildings & homes in variable climates

Disadvantages to Consider:

Higher initial cost than HRUs

- Slightly more complex maintenance due to additional components

- May not be necessary in dry, temperate climates

Whether you're upgrading an HVAC system or building from scratch, an Energy Recovery Unit is a smart investment for long-term comfort and savings—especially where both temperature and humidity matter!
