CO2 Based Heat Pump Water Heating Systems: Save on Utilities while Saving the Planet

Water heating accounts for around 18% of the average home’s electricity bill. If you’re choosing a water heater for your new home or wanting to replace an old system, you’ll want to consider choosing a heat pump water heater that uses CO2 refrigerant. CO2 heat pumps are attractive for two reasons: first, the co-efficient of production means you can heat a lot of water for not a lot of money and second, CO2 refrigerant has a global warming potential of one, compared to hundreds, if not thousands in other systems. At Small Planet Supply we have CO2 based water heating systems for single-family, multi-family and commercial applications.

Menlo Park: WaterDrop Pre-Manufactured Plug and Play Central Heat Pump Water System Proves Off-Site Construction Works

Last month WaterDrop Systems completed installation and “handed over the keys” to a 14-skid pair project utilizing pre-manufactured plug and play heat pump water heater systems in Menlo Park, California.  This project was the first large scale system manufactured by WaterDrop Systems. At this monumental moment, it seemed like a good time to share the history of how these systems progressed from an idea to reality. We also thought it would be a great chance to give a virtual tour of the installed skids in Menlo.

Three Innovative Ways to Use SANCO2 Water Heaters
Three Innovative Ways to Use SANCO2 Water Heaters

SANCO2 Heat Pump Water Heaters were a paradigm shifter when Small Planet Supply began carrying them in 2017.  It seemed incredible that a water heater could achieve a COP of up to five while using a natural refrigerant with a GWP of less than one.  The ability of a SANCO2 heat pump to produce an abundance of hot water began to spark the imagination of homeowners, innovators, and mechanical system designers alike.  This blog post highlights three ways to utilize a SANCO2 in projects of all sizes, from smallest to biggest.
