Savings estimate

Estimate your savings with electric resistance tank water heater on a utility TOU plan.

ⓘ Some utility plans include a “demand charge” based on your highest power draw (kW) during peak windows. ThermoSave may reduce that peak by avoiding water-heater heating during those windows.

We use typical values for homes like yours. You can adjust them below (optional).

Tip: Use the energy charge (¢/kWh). If your bill shows generation + delivery, add them.

Water-heating kWh estimates are derived from typical EnergyGuide “Estimated yearly energy use” values for electric tank water heaters. Learn more. Actual results depend on rate plans, household usage, and water heater behavior. We do our best to keep this accurate. If something looks off, email hello@thermosave.com.
