Design
Plate heat exchanger X
Copper-brazed plate heat exchanger for optimum transmission values
Thermostatic head X
Depending on the requirements, the desired hot water temperature can be set using the thermostatic head.
Loading pump (primary side) X
Takes the hot water for the heating from the accumulator tank and conveys the cold return back into the tank.
Power box X
All the necessary electrical connections are located in the splash-proof power box.
Water switch X
When hot water is tapped, this is activated and switches on the loading pump for domestic hot water.
Push-in connection for circulation unit X
Easy connection for an optional circulation pump.

Convenient and flexible
+ Fresh, vital hot water in the required quantity without wait times
+ Space-saving thanks to compact design and possibility of installation on the AccuWIN or AccuWIN Solar accumulator tanks
+ Hot water temperature can be selected
+ Can be mounted either on the wall or directly on the AccuWIN or AccuWIN Solar accumulator tank
Efficient
+ Large draw-off amount due to large heat exchanger
+ No losses due to downtime of a hot water tank, as hot water is only produced when needed
+ No mixing of the accumulator tank due to low return temperatures
Reliable and safe
+ Avoidance of Legionella growth due to the use of the flash heating principle for hot water provision

Functional description
When the water tap is turned on in the house, the water switch activates the loading pump. The hot water from the accumulator is transported to the heat exchanger, which heats up the cold water to the set hot water temperature. The admixture via the mixer circuit ensures the constant outlet temperature of the hot water. At the same time, it also ensures that only as much hot water as necessary is taken from the accumulator tank and that the return flow into the accumulator tank is as cold as possible.
When the hot water requirement has been met (water tap is turned off again), the loading pump is switched off again. Therefore hot water is provided according to demand, preventing any losses of the hot water tank resulting from downtime or the formation of legionella (bacteria).
