MelPump Changelog Smarter savings, wider coverage, better control

Smarter savings, wider coverage, better control

This update brings more choice to Smart Energy, more reliable hot water control, and a clearer picture of your heat pump’s efficiency.

  • Electricity prices for 40+ regions with ENTSO-E. Our new pricing provider expands the choice of European electricity markets available in MelPump, helping more users plan heating around cheaper energy.
  • Your cheapest hours, your strategy. Smart Energy now gives you more control over what counts as a cheap period. Choose the cheapest hours of the day, set a price threshold, or combine both to tailor home heating and hot water boosts to your preferences.


  • Summer Eco that respects your hot water boost. We’ve fixed a conflict that could interrupt manually triggered hot water heating outside the Summer Eco schedule. Your boost can now finish while Summer Eco’s automatic cycles continue to follow your schedule.
  • Compare hot water efficiency. Energy Results Comparison now includes a dedicated domestic hot water COP alongside space heating COP. See how efficiently your heat pump heats water compared with other installations—even during summer, when space heating is off.
