Key Features

No Phase Change

ZETA boilers heat water directly, reducing heat-transfer steps and the need for additional equipment.

Fast Startup

ZETA boilers can remain ready in warm standby, allowing steam or hot water production to begin quickly when demand increases.

  • Warm startup: 60–120 seconds from warm standby
  • Cold startup: 1–2 hours

Wide Modulation Range

Raising or lowering the water level in the inner tank changes the submerged electrode surface, providing a 3–100% modulation range to closely match hot-water demand.

High Temperature

ZETA hot-water boilers support high-temperature applications up to 180°C / 350°F.

Safer Low-Water and Standby Operation

At a low water level in standby mode, ZETA boilers consume less than 50 kW without producing heat. This supports safer standby operation by reducing explosion risk while keeping the boiler ready for service.
