Mixergy

Why it's on ClimateTicker

Mixergy makes patented smart hot water cylinders that cut residential hot water energy consumption by up to 40% via top-down stratified heating and machine-learning demand control, directly reducing Scope 2 household emissions and enabling deeper integration of solar PV and heat pumps. The core technology has been independently validated by the Energy Savings Trust and Energy Systems Catapult, and real-world deployments (e.g., Birmingham City Council) provide quantified carbon savings, giving the climate case meaningful credibility. However, as a private SME, Mixergy publishes no formal sustainability report, holds no SBTi, CDP, or B-Corp certification, and product-level savings figures vary widely across marketing materials, leaving institutional-grade disclosure notably thin.
