In today’s energy-conscious world, businesses are under increasing pressure to operate more efficiently while reducing their environmental impact. One of the most effective—and often overlooked—ways to do this is through heat recovery in refrigeration.
At Green Cooling, we specialise in turning what was once considered ‘waste’ into valuable, reusable energy that can significantly cut operational costs and carbon emissions.

What Is Heat Recovery in Refrigeration?
Every refrigeration system generates heat as a by-product of the cooling process. Traditionally, this heat is expelled into the atmosphere—completely wasted. Heat recovery technology captures that expelled heat and repurposes it, typically for:- Generating hot water
- Space heating
- Process heating
How Does It Work?
A heat recovery system is installed within the refrigeration circuit to extract heat from the refrigerant before it is released. This recovered heat is then transferred to a secondary system—usually a water tank or heating unit—where it can be stored and used later.Systems like Green Cooling’s advanced Heat Recovery Units are designed to work seamlessly with CO₂ and hydrocarbon-based refrigeration systems, ensuring efficient integration and performance.
The Key Benefits of Heat Recovery
At Green Cooling, we’re committed to helping clients embrace the shift to sustainable technology. Our range of natural refrigerant solutions includes:- Lower Energy Bills : By reusing the heat you’re already producing, your business reduces the need for conventional water heating systems—leading to significant utility savings.
- Reduced Carbon Emissions: Cutting down on gas or electric water heating reduces your carbon footprint and helps meet environmental targets.
- Improved System Efficiency:Removing heat from the refrigeration system more effectively can enhance cooling performance and reduce compressor workload.
- Quick Return on Investment:Many businesses see a return on investment within 2–3 years, thanks to energy savings and potential tax incentives
- Eligible for Energy Efficiency Funding:In the UK, systems that include heat recovery may qualify for government-backed schemes such as the Enhanced Capital Allowance (ECA) or local decarbonisation grants.
Industries That Benefit Most
- Food Manufacturing:Large-scale production environments often run both refrigeration and hot water systems simultaneously. Heat recovery captures wasted energy and redirects it into daily processes like cleaning or ingredient prep.
- Hospitality & Hotels:Hotels with high hot water demand—for kitchens, bathrooms, and laundry—can significantly offset energy costs by recovering waste heat from cold rooms and chillers.
- Healthcare & Laboratories:Facilities that operate ultra-low temperature storage and simultaneous heating functions can use heat recovery to reduce system load and improve resilience.
- Retail & Supermarkets:Supermarkets generate enormous amounts of heat from display refrigeration. Instead of exhausting this heat, it can be harnessed to support building heating or water systems.

Frequently Asked Questions (FAQ)
Yes, many systems can be retrofitted with heat recovery, although the level of efficiency will depend on system design and layout. Our team can assess feasibility during a site consultation.
Savings vary by system size and application, but businesses often reduce energy costs for hot water and heating by 20–40%, with ROI typically within 2–3 years.
While larger systems offer the greatest return, smaller businesses with consistent heating and refrigeration demand—like boutique hotels or restaurants—can also benefit.
Absolutely. Green Cooling’s heat recovery systems are specifically designed to integrate with natural refrigerant technologies.
Yes. By reducing the need for fossil-fuel-based heating, heat recovery contributes directly to emissions reduction and net-zero goals.
