District heating transfer station WP-Max Grid Kompakt

District heating transfer station WP Max-Grid Kompakt

The sophisticated combination of heat pump, transfer station and DHW tank

The WP Max-Grid Kompakt transfer station with integrated heat pump and DHW cylinder forms the complete energy centre of a building. It contains all the necessary components for heating and drinking water preparation and stands for maximum efficiency. It is suitable for use in innovative heating and energy concepts (heating network 4.0), primarily in residential areas, but also in industry and commerce. This extraordinary combination of interfaces to classic local heating and cold local heating in one product opens up a wide range of applications.

Special features:

Inverter control:

The WP Max-Grid series can cover a very wide performance spectrum in the field of heat generation or cooling via the standard integrated speed control by means of inverter technology. Thus a wide range of applications is available. Inverter technology, for example, also permits power regulation in order to use PV electricity as required for heating or cooling purposes. This heat pump offers you the highest savings potential because it always delivers the right output and automatically adapts to the current energy demand of the living space at any time of the year.


Flexible source network temperatures:

By equipping the WP Max-Grid with the Grid technology patented by ratiotherm, the user is able to tap any heat source as a source for the heat pump. Even if the source temperatures change constantly within a temperature window of 10-55°C (e.g. process heat during various work steps), the WP Max-HiQ always works at the optimum operating point. For the operation of the plant this means a minimization of the operating costs with maximum coefficient of performance (COP).


Transfer station - heat pump combination:

The heat pumps of the Grid series are equipped with a transfer station for "classic" local heat at a temperature level of 60-95°C. The heat pumps are also equipped with a heat transfer station for "classic" local heat. This heat can be transferred directly to the heating system in the building. The additionally integrated heat pump is deactivated in this operating state. As soon as the heating network is lowered to low temperatures (10-55°C), the heat pump takes over the temperature range set by the heating system and hot water to up to 75°C. The heat pump is then switched off in this operating state.


Integrated DHW cylinder:

The WP Max-Grid Compact has an integrated 200 litre DHW cylinder or a buffer cylinder with corresponding fresh water technology, depending on the version. This system ensures sufficient hot water and comfort in the heating behaviour at all times. This combination reduces the need for expensive space inside the building to a minimum.
