How it works

A heat pump and a hot water cylinder, in one unit.

A small heat pump on top of the tank draws in air, moves heat from it into the stored water, and releases the cooler air. The unit stands indoors.

01 / 04

Two sizes, one footprint.

The ENTH-200 holds 204 litres and the ENTH-250 holds 250. Both stand on the same 600 × 625 mm footprint.

02 / 04

Heat from the air. Hot water for your home.

The heat pump uses heat in the air to warm the water in the tank. The air leaving it is cooler. Your installer can use room air or suitable ducting to outside. The heat pump operates between −7°C and +43°C.

70°C from the heat pump alone.

The heat pump heats the stored water to 70°C on its own. The 1,600 W back-up element takes it to 75°C.

In the home

One indoor unit. Airflow planned to suit your home.

One unit on a 600 × 625 mm footprint. It needs clear space around it to draw its air, or ducts to outside.

Where it fits

The jobs where a full heat pump system does not fit.

  • 01

    Electric-only cylinders

    Homes heating water on the immersion. A heat pump does the heating instead, with the 1,600 W element kept as back-up.

  • 02

    Off the gas grid

    Homes paying for oil or LPG deliveries to heat their water.

  • 03

    Flats and terraces

    An indoor water heater can be an option where space is limited. Your installer still needs to check airflow, clearances, drainage and any ducting.
