Why We Don’t Use Glycol

Posted on December 2, 2022

In this video HPIN Training manager Jamie talks about the reasons we don’t use glycol in our systems and what we use instead.

Let’s delve into the reasons why glycol isn’t preferred in our air source heat pump systems.

When it comes to maintaining efficient and effective air source heat pump systems, the choice of coolant matters.

Specific Heat Capacity Concerns

One of the primary reasons we avoid glycol is its impact on water’s specific heat capacity.

Expansion Issues and System Complexity

Glycol alters the expansion dynamics of water, necessitating additional components like expansion vessels, which can complicate system design and maintenance.

Practical Considerations: Messiness and Maintenance

Glycol’s inherent messiness, marked by its blue dye, poses a challenge in terms of maintenance and aesthetics.

Cost Considerations and Equipment Requirements

Maintaining glycol-based systems incurs recurring expenses, including the need for specialized equipment like refractometers for testing and monitoring glycol levels.

Eco-Friendly Alternatives: Anti-Freeze Valves

Instead of glycol, we rely on anti-freeze valves as a more eco-friendly solution to prevent outdoor unit freezing.

Conclusion: Emphasizing Efficiency and Sustainability

Thank you for exploring the drawbacks of glycol in air source heat pump systems with us. Stay tuned as we continue to explore sustainable practices and innovations in heating technology.

Understanding why glycol isn’t the preferred choice in air source heat pump systems illuminates the importance of exploring eco-friendly alternatives and prioritizing efficiency in HVAC installations. Join us in our journey towards sustainable heating solutions.
