Heat pumps

A heat pump is not just a thermostat. It is one of the home's most important energy assets.

Heat pump energy management means coordinating comfort, weather, electricity prices, solar generation and battery reserve so heating and cooling decisions make sense for the whole home.

Short answer: a heat pump should not optimize in isolation. It should know when energy is cheap, when solar is expected, what the home battery must reserve and how much thermal flexibility the building has.

The hidden flexibility in comfort

Buildings have thermal inertia. They can often pre-heat or pre-cool slightly before an expensive period, then coast through part of that period without a noticeable comfort penalty. This is not about making the home colder or hotter to save a few cents. It is about using the building intelligently.

Why ordinary schedules are too simple

A fixed schedule cannot see tomorrow's weather, solar forecast, battery state, price curve or EV charging deadline. It may run at a technically correct time and still be economically wrong for the home.

What a better control loop considers

  • Indoor comfort target and acceptable temperature range.
  • Weather forecast and expected heating or cooling demand.
  • Solar production forecast and likely surplus windows.
  • Battery reserve and backup requirements.
  • Dynamic tariff windows or peak-price periods.
  • Other large loads such as EV charging or hot water.

Where GridPassport fits

GridPassport treats comfort as one of the three north stars, alongside savings and resilience. Heat pump decisions should save money only when they keep the home calm and livable.

FAQ

Heat pump management questions.

Why should a heat pump be connected to a home energy management system?

A heat pump is a large flexible load. If it can respond to weather, electricity prices, solar production and comfort limits, it can often move part of its work to better moments.

Can heat pump optimization make the home uncomfortable?

It can if price is treated as the only goal. A responsible system uses comfort as a constraint and shifts only the part of heating or cooling that the building can absorb.

Is heat pump management only useful with dynamic tariffs?

No. Dynamic tariffs make timing more valuable, but heat pump coordination can also help with solar self-consumption, peak reduction, battery reserve and resilience.
