Tech Demo Series – The SANCO2 WaterDrop System

Past Event: Mar 25 @ 10:00 am – 1:00 pm


ZEBx partners with BCIT and three CO2-based DHW heat pump suppliers to present a three-part, in-person Technology Demonstration Series workshops taking place from Feb to Apr 2022.

As we move up the BC Energy Step Code ladder while cutting back on operational emissions, we can’t lose sight of embodied carbon If you’ve been reading ZEBx’s case studies on high-performance buildings, you may have noticed a recurring theme. Heat pumps are being used to generate domestic hot water. As more and more regulations target emissions reductions, this will become far more common. Not all DHW heat pumps are created equal though. Some use refrigerants with high global warming potential, while other heat pumps use refrigerants with ultra-low GWP like CO2.

This event featured the Small Planet Supply’s SANCO2 WaterDrop system – a drop-in solution for large buildings which uses CO2 as the refrigerant.


Brian Culler – Brian Culler holds a B.S. in Mechanical Engineering from Gonzaga University and has 15 years of experience in industrial refrigeration and domestic water heat pumps.  His work has included design, applications, equipment startups and service.  Brian is currently the General Manager of Commercial Water Heating at Small Planet Supply in Olympia, WA.  Small Planet builds packaged CO2 heat pump hot water systems for commercial and multi-family buildings.

Albert Rooks – Albert Rooks has been passionate about energy efficient construction since 2009.  He worked to establish and strengthen the Passive House Standard in North America and in 2010 he founded Small Planet Supply Inc., in Washington state. Featuring both a physical warehouse location and an online store, the company initially imported and distributed passive house components, including building tapes, membranes and mechanical systems. Realizing the need for builder education in using new products, the company began hosting educational workshops to increase designer and builder confidence in including these high-efficiency products in their builds.  In 2016, Small Planet Supply opened a Vancouver, Canada location to provide products and training in response to Vancouver’s Greenest City Initiative.  Albert’s future focus will include procurement and production of high-efficiency mechanical systems, including WaterDrop as well as other energy-efficient products and mechanical systems for new and retrofit applications.
