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.
Using heat pumps to generate hot water isn’t a futuristic technological dream. These heat pumps are here now, available from BC suppliers and are a key strategy to help reduce emissions from both new and existing buildings. Not all DHW heat pumps are created equal though. Some use refrigerants with a high global warming potential, while others use refrigerants with an ultra-low GWP – like CO2.
This event featured Mitsubishi Electric’s new CITY MULTI QAHV., capable of reaching a CoP of 4.11 and operating in temperatures as low as -25 C. This heat pump was on display in BCIT‘s fascinating High-Performance Buildings Lab for this workshop.
