Smart Water Heaters Could Replace New Power Plants | Luke Winston-Almanzar
August 6, 2026
What if your water heater could lower your energy bills, keep your showers hot, and help stabilize the electric grid? Residential water heating accounts for roughly 20% of household energy use, yet most systems still operate without intelligence. Luke Winston-Almanzar, CEO and Co-founder of Reservoir, believes that changing this could unlock one of the biggest climate opportunities hiding inside our homes.
In this episode of Hardware to Save a Planet, host Dylan Garrett speaks with Luke about how intelligent heat pump water heaters use predictive software to store thermal energy when electricity is cleaner and cheaper, effectively turning every home into part of a distributed energy network. He explains why better customer experience, not efficiency alone, drives adoption, how integrated hardware dramatically lowers installation costs, and why smart water heaters can evolve into platforms that improve home energy management while reducing emissions at grid scale.
Hardware to Save a Planet is brought to you by Synapse. We are a global product development and engineering firm that partners with visionary companies to design, develop, and realize breakthrough hardware and AI-powered innovations that advance climate technologies.
