Hot Water Generation Systems
Efficient and sustainable hot water solutions for commercial and industrial needs.
Green Cooling provides advanced hot water generation systems that combine energy efficiency with environmental sustainability. Our systems utilise CO2-based heat pump technology to deliver high-temperature potable hot water up to 80°C, making them ideal for applications requiring large hot water volumes. By recovering waste heat from cooling systems or operating as standalone heat pumps, our solutions significantly reduce energy consumption, operational costs, and carbon emissions.
What Are Hot Water Generation Systems?
Hot water generation systems utilise innovative refrigeration-based technology to produce hot water for commercial and industrial applications. By capturing waste heat from cooling processes or using renewable energy sources, these systems provide an energy-efficient alternative to traditional fossil fuel boilers. Green Cooling’s systems include features like hybrid heat pumps and high-efficiency CO2 systems, designed to meet high-capacity demands while supporting sustainability goals.
