Independently of any other heating equipment, the Vitocal 161-A DHW heat pump heats domestic hot water, inexpensively and efficiently, by utilising heat from the room.

Compact Vitocal 161-A heat pump for efficient DHW heating

The compact Vitocal 161‑A heat pump is equipped with all components required for efficient DHW heating. The space efficient casing houses the heat pump module, as well as a 300  l DHW cylinder, plus the control unit.

The Vitocal 161‑A utilises indoor air to heat DHW economically.  It is as suitable for detached houses as for smaller commercial enterprises. Ideal application areas include bakeries and situations where the indoor air needs to be cooled (for example in a wine cellar or a cooled larder).

As an option, the heat pump may be supplied without internal indirect coil for mono mode operation or with integral indirect coil for use in a dual mode heating system, for example in combination with a solar thermal system.

For either recirculation or extract air

The recirculation air version, Vitocal 161-A, utilises air straight from the room where it is installed. Part of the heat from the air that is drawn in is extracted and raised by the heat pump to a useful temperature level (up to 65  °C for increased DHW hygiene). Moisture is extracted from the interior, protecting the fabric of the building and improving quality of life for all occupants.

By replacing the recirculation air cover with an extract air cover (accessory), the Vitocal 161-A can also be used as an extract ventilation unit with heat recovery. The warm extract air is removed from rooms such as the bathroom or kitchen via ducts. This air is then dehumidified and any pollutants are removed.
