Inflation and rising energy costs have heavily impacted household energy consumption rates, making efficient technologies like heat pump water heaters (HPWHs) financially out of reach. To address this, we developed the “Retro Loop”—an add-on heat pump module that retrofits with existing electric water heater tanks. Designed to heat water during off-peak hours, the Retro Loop reduces energy consumption and cuts utility bills, without requiring homeowners to invest in a completely new system. By reducing utility bills by 67-80%, our product provides substantial relief from rising energy expenses.
