The AI code worked out my heat costs: 6.5p per kWh of heat

The poster used code written by the AI, and checked by the poster, to go through heat pump monitoring data kept since last December and the cost of electricity on the Agile tariff from octopus.compare. It gave a cost of 6.5p for each kWh of heat.

How it works

  1. The AI writes code
  2. The poster checks the code
  3. The code goes through the heat pump monitoring data and the Agile electricity costs
  4. It gives a figure of 6.5p per kWh of heat

Why it’s worth knowing

Most people never work out what a unit of heat from their own heat pump costs. The poster fed the AI code their own monitoring and tariff data and got a straight answer: 6.5p per kWh of heat.
