Heat pumps provide sufficient energy at different temperature conditions in order to offer a high heating and hot water convenience. For the case
that this is not sufficient, the PAW BoostBloC® is activated and provides additional thermal energy via an instant water heater.
The post-heating module is a preassembled group of fittings for heat pump applications.All electronic components such as the instant water heater or the pump
can be isolated by means of the ball valves.They can thus be maintained easily without draining the heating or charging circuit system.
The PAW BoostBloC® is mounted directly at the wall and serves to post-heat a storage tank.The system can be extended by further components as a domestic hot water module or a heating distribution manifold.
The station requires an additional controller and is normally actuated by the heat pump controller.It is connected to the external controller via
the enclosed small distribution manifold.Via a post-heating request (230 V) of the controller, the power contactor is actuated, which is integrated in the small distribution manifold.In the type with contactor,
there is no power control; only the one preset power (8.8 kW) of the tubular heating element is actuated.
Depending on the controller and connection type, the pump can be connected simultaneously to the heat generator or separately.
For an independent valve control of the integrated flow stratification, a continuous phase as well as a further switch contact are required.

Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist]. The following must be observed during installation and commissioning: - relevant local and national regulations - accident prevention regulations of the professional association - instructions and safety instructions mentioned in these instructions.
