Three heating modes

  1. ECO mode allows the ZS500 to operate at as little as 50% power to reduce costs.
  2. Smart mode operates between 50% and 100% power capacity.
  3. Boost mode allows you to run your ZS500 at 100% power, ideal for heating your pool quickly.

Vertical fan unit for discreet installation

Unlike conventional heat pumps that require a 5-metre radius of clear space to install, the ZS500 has a vertical fan system, allowing it to be concealed behind a wall or trees without compromising its performance.

User-friendly controls interface

The user-friendly and simple design of the ZS500’s controls interface allows you to set your desired water temperature and select your heating mode in a single step.
