Heat Pump Carbon Forecast

See your daily carbon savings forecast for the week ahead — how much CO₂ an air source heat pump could save vs a gas boiler at your UK location

20°C is the UK average home temperature

Powered by real heat pump data

Our model is trained on millions of data points from hundreds of real UK heat pumps, spanning multiple years of operation.

Data from HeatpumpMonitor.org

Open source heat pump monitoring — thank you for making this data publicly available

How the forecast works

  • 1.We fetch weather forecasts for your location and UK wind farms to predict grid carbon intensity
  • 2.Our ML model forecasts daily heat pump emissions based on temperature and grid conditions
  • 3.We compare against an 85% efficient gas boiler (typical UK condensing boiler) at 202 gCO₂/kWh

This tool is in beta

Results are estimates based on statistical models and weather forecasts. Actual savings depend on your specific heat pump, home insulation, and usage patterns. Carbon intensity forecasts are only available for ~48 hours ahead.
