Bivalent Design

Design and optimise bivalent heating systems for maximum efficiency

Bivalent systems combine the strengths of renewable and traditional heating sources, typically pairing a heat pump with a boiler or electric heater. This hybrid approach ensures maximum energy efficiency by using the heat pump as the primary source and only activating the secondary source during peak demand or colder temperatures. Our software takes the complexity out of designing these systems by helping you determine the ideal bivalent point, ensuring system balance, cost savings, and year-round comfort. It’s the smarter way to future-proof any heating setup.
