Akva Lux II, fully insulated

Applications
Akva Lux II is a fully insulated instantaneous water heater featuring high performance. It meets the future energy demands for low energy consumption and very low standby heat losses. It is especially suitable for large villas with for instance several bathrooms or jacuzzi and for the large family, for which an exceptionally large amount of water is required. The Akva Lux II is also very suitable for small apartment houses with 2-4 apartments.

Bypass (thermostatic circulation)
The water heater is supplied with a thermostatically controlled bypass, which ensures that hot water is produced immediately, when tapping starts. The bypass temperature is set with due consideration of the best possible DHW comfort and economy.

Domestic hot water recirculation
The water heater is prepared for domestic hot water circulation. If the household piping includes hot water recirculation the water heater must be connected to the hot water recirculation system and a circulation pump and a non-return valve must be mounted on the circulation pipe and a safety valve must be mounted in the DCW inlet. The pump must be installed so that it pumps towards the water heater. Domestic hot water recirculation ensures that hot water is available at the tapping point without waiting time and waste of water. The circulation temperature is set independently of the set DHW temperature. This ensures the best possible DHW comfort, very low standby losses and thus a very good district heating economy.

Heat exchanger for DHW heating
The water heater is based on a brazed, highly efficient plate heat exchanger type XB 06H-1 26, XB 06H-1 40 or XB 06H+ 60, which is controlled by a thermostatic and pressure controlled DHW controller, Danfoss PTC2+P with integrated differential pressure controller and energy saving function, which ensures that the heat exchanger is cold during standby. After completion of the tapping process, the controller immediately blocks the district heating flow, to avoid standby, so the losses and to protect the heat exchanger from the formation of lime scale and growth of bacteria. The heat exchanger is cold during standby, so the heat loss is very low. The integrated differential pressure controller compensates for variations in supply temperature and varying differential pressure and thereby ensures a constant hot water temperature at all times.
