Optiheat Terra All-in-One

This compact water/water heat pump with inverter technology is developed and produced in Münsingen – for maximum efficiency and low operating costs. It is ideal for single-family homes and apartment buildings with radiators and underfloor heating, reliably covering heating and hot water requirements. The heat pump is designed to keep installation costs very low: it scores with its proven and optimised all-in-one concept, in which components required for installation, such as circulation pumps, DHW changeover valve and emergency heating element, are already built in. It also features flexible pipe routing that can be adapted to the room. Thanks to the low refrigerant charge, there is no need for a site-specific safety concept for propane. In addition to heating and hot water preparation, free cooling is also possible. Several units can be combined if required. The heat pump is barely audible during operation and can be conveniently operated via the integrated display or app. The heat pump can be easily integrated into an energy management system, thus contributing to an increase in the self-consumption of photovoltaic systems. We recommend a LAN connection via the router provided by the building owner.
