Our verdict

Is an iStore heat pump right for you?

The installers' clear favourite: iStore won their vote in 2025 and 2026 by a wide margin. On paper its specs and 5-year warranty are only average, so its rating rests on how well it works in practice.

Rated 6.8/10, #4 of 16 brands we rate for heat pump hot water.

A good fit if

  • You want the heat pump installers most often choose
  • Your household needs 270 litres or less

Maybe look elsewhere if

  • You want the longest warranty
  • You need a tank over 270 litres
