Can you keep a home warm using only green electricity?

In this simulation game, you control a heat pump to maintain comfort while reducing CO₂ emissions. Your goal is to heat a building and a hot water tank using electricity from wind and solar sources while avoiding fossil fuels like coal and gas.

Each level challenges you to balance comfort, efficiency, and sustainability by heating at the right moments.

🎮 Game overview:

• Heat only when green electricity is available

• Maintain room temperature and the hot water in the tank

• Play through multiple levels of increasing difficulty

• Learn facts about heat pumps and their role in climate protection
