The PAW HomeBloC® Digital is a highly efficient, fully electronically controlled home transfer station for decentralised domestic hot water heating and heat supply. The integrated differential pressure control in conjunction with a speed-controlled pump enables energy-optimised and hydraulically balanced operation. Components that cause pressure loss, such as diff erential pressure controllers, are no longer required. Domestic hot water is heated as required in the high-performance heat exchanger in the station. The temperature is regulated to the exact degree. The generously dimensioned heat exchangers enable operation with an extremely low primary fl ow temperature. The HomeBloC® Digital is therefore ideally suited for the most e ffi cient operation with a heat pump. The digital communication via Modbus and the possibility to connect it to the building control system makes the HomeBloC® Digital SmartHome ready!

Your advantages with the HomeBloC® Digital:
This HomeBloC® Digital WR version is designed to be connected to an unmixed circuit. The temperature of the flow line is provided by the central heat generation system, dependent on the weather and on the demand.
This temperature can be used for heating domestic water as well as for heating the rooms.
As a result of the differential pressure control of the pump, the hydraulic balancing of all stations is ensured. An oversupply (may be accompanied by noises) or an undersupply of individual areas is therefore surely excluded.
Application example:
A property has one or multiple radiator circuits. The HomeBloC® Digital WR version suits perfectly for this application.
The flow temperature can be provided directly from the radiator to the room.
The controller is pre-set to the initial pressure of 100 mbars for the operation with standard thermostatic valves.
The HomeBloC® Digital WF version is designed to be connected with a mixed heating circuit.
The temperature of the flow line is provided by the central heat generation system, dependent on the weather and on the demand. This temperature is sufficient for heating domestic water in the heat exchanger of the station.
The temperature of the flow line, which must be available for heating domestic water, is too high for heating a low-temperature or a radiant panel heating system (e.g. radiant floor or wall heating).
Therefore, the type WF station is equipped with a mixing valve unit. The heating circuit flow temperature is calculated as a function of the outside temperature or the room temperature by means of a heating curve - or is set as a fixed value / constant temperature.
The pump is regulated to a specified differential pressure. This ensures the hydraulic balancing of all stations. An oversupply (may be accompanied by noises) or an undersupply of individual areas is therefore surely excluded.
Application example:
A property has one or multiple radiator floor circuits. The HomeBloC® Digital WF version suits perfectly for this application.
The flow temperature can be provided directly from the radiant panel heating to the room. The controller for this version is designed for the initial pressure of 150 mbars for the operation with standard radiant floor heating systems.
The HomeBloC® Digital WRF version combines the functionality of the WR and WF versions.
Radiator circuits and radiant floor circuits can be operated simultaneously.
The temperature of the flow line is provided by the central heat generation system, dependent on the weather and on the demand. This temperature is sufficient for heating domestic water in the heat exchanger of the station as well as for operating the radiators that are connected directly. The radiant floor heating is operated in parallel via the outgoing injection-type circuit.
Application example:
A property has one or multiple radiator floor circuits as well as a radiator circuit. The HomeBloC® Digital WRF version suits perfectly for this application.
The flow temperature of the radiant panel heating is controlled via the injection-type circuit, the required differential pressure is set at the self-regulating pump. For this version, the controller is pre-set to the initial pressure of 100 mbars for the operation with radiator heating systems.
Improve the efficiency of your overall system even further – with a DHW postheating system!
The PAW HomeBloC® Digital with instantaneous water heater (DLE) differs in particular from the stations without instantaneous water heater.
The drinking water is preheated in the high-performance heat exchanger and reheated to the desired outlet temperature to the exact degree with the help of the instantaneous water heater.
The integrated instantaneous water heater enables extremely low heating flow temperatures, which would not be sufficient for domestic hot water heating.
The principle of DHW postheating using the electric instantaneous water heater enables the most efficient operation of a heat pump. Best COP values can be achieved.
