The advantages of the WP Grid-HiQ C series at a glance:
Special features:
Inverter control:
The WP Grid-HiQ C series can cover a very wide range of heating and cooling capacities thanks to the standard integrated speed control using inverter technology. This opens up a wide range of applications. The inverter technology also allows, for example, the output to be regulated so that PV power can be used for heating or cooling as required. This heat pump offers you maximum savings potential, as it always delivers the right output and automatically adapts to the current energy requirements of the living space in every season. The name of each inverter heat pump includes the term Flex (F) to indicate flexible speed. The systems therefore have an F in their type designation.
Flexible source network temperatures:
Thanks to the WP Grid-HiQ C being equipped with ratiotherm’s patented HiQ technology, users can tap into any heat source for the heat pump. The name comes from the high (Hi) Q source network temperature, i.e. HiQ. Even if the source temperatures constantly change within a temperature range of 10-55°C (e.g., process heat during various work steps), the WP Grid-HiQ C always operates at the optimum operating point. For the operation of the system, this means minimized operating costs with maximum coefficient of performance (COP).
Transfer station-heat pump combination:
The heat pumps in the Grid series can be equipped with a transfer station for “classic” local heating at a temperature level of 60-95°C. The output to be transferred via this station can be customized to your specific requirements. The heat energy from the local heating system can be transferred directly to the heating system in the building. The additional integrated heat pump is deactivated or in standby mode 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 increase specified by the heating system and hot water up to 72°C.
Buffer storage and fresh water technology:
As a complete boiler room system, the WP Grid-HiQ C can of course also be equipped with a buffer tank in various sizes. The tank and the necessary safety components are concealed beneath an attractive cover. A fresh water module for hygienic drinking water supply is also integrated. This combination, paired with an internal control module tailored to the application, replaces the entire boiler room control system. These features are part of the name of our systems and are designated with C for Compact in the type designation at ratiotherm.
