Abstract
The present inventive concept relates to a method for adjusting a water temperature in a water recirculating device. The method comprises determining a first parameter associated with a first water path; determining a second parameter associated with a second water path; determining a setting of a mixing valve arrangement based on the first and second parameter; and adjusting a water temperature of water output by a water outlet based on the setting of the mixing valve arrangement. The invention also relates to a water recirculating device configured to adjust a water temperature of water output by a water outlet based on the setting of the mixing valve arrangement.

A method for adjusting a water temperature in a water recirculating device comprising:
- a water outlet configured to output water;
- a collecting element configured to collect water output from the water outlet;
- a discard path configured to discard water from the water recirculating device;
- a recirculating path in liquid communication with the collecting element and the water outlet;
- an external mixing valve arrangement in liquid communication with the recirculating path, the external mixing valve arrangement accepting as inputs at least hot and cold water from a hot and cold water source respectively;
- a flow path divider arranged in the recirculating path downstream of the external mixing valve arrangement, wherein the flow path divider is arranged to divide the recirculating path into a first water path and a second water path;
- and
- a mixing valve arrangement configured to accept as inputs water from the first and second water path and to output water to the water outlet;
- wherein the method comprises:
- determining a first parameter associated with the first water path;
- determining a second parameter associated with the second water path;
- determining a setting of the mixing valve arrangement based on the first and second parameter;
- and
- adjusting a water temperature of water output by the water outlet based on the setting of the mixing valve arrangement.
