Thermia Elve L, 400V + Idun Total EQ, 400V

Complete air/water heat pump for heating, cooling and domestic hot water

The Elve L + Idun Total EQ is a complete and energy-efficient solution for heating, cooling and domestic hot water production. The Elve L provides efficient heat and cooling generation and is combined with the Idun Total EQ, a floor-standing indoor unit with integrated controller, hot water tank, extra buffer volume and electric auxiliary heater.

The Elve L combines powerful performance with quiet operation and reliable heating, even at outdoor temperatures down to -25°C. With a flow temperature of up to 75°C, it is suitable for both modern low-temperature systems and existing heating installations. Active cooling is also possible.

The heat pump uses the natural refrigerant R290 (propane) and combines high energy efficiency with modern, quiet and reliable operation. Thanks to the integrated Wi-Fi and 4G connectivity, the installation can easily be monitored and managed remotely.

The Idun Total EQ is the central indoor station of the installation. The floor-standing indoor unit integrates a 184-litre hot water tank, an additional 60-litre volume tank, a 12-litre expansion vessel, an energy-efficient class A circulation pump with an additional circulation pump, a 3-way valve for switching between space heating and domestic hot water, and an adjustable electric auxiliary heater of 1.5 to 9 kW. Thanks to the extra system volume and the second circulation pump, no separate buffer tank is needed in many installations.

The intelligent Thermia controller adapts the operation of the heat pump to the current demand for heating and domestic hot water. The electric auxiliary heater can be used to support peak loads, for extra hot water capacity or as a back-up when needed. The result is an integrated system that combines comfort, efficiency and operational reliability.
