Thermia Elve XL, 400V + Idun Total 300, 400V

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

The Elve XL + Idun Total 300 is a complete and energy-efficient solution for heating, cooling and domestic hot water production. The Elve XL provides efficient heat and cooling generation and is combined with the Idun Total 300, a floor-standing indoor unit with integrated controller, a large hot water tank and electric auxiliary heater.

The Elve XL 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 300 is the central indoor station of the installation. The floor-standing indoor unit integrates a 300-litre hot water tank, an energy-efficient class A 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. Combined with the Elve XL, the installation delivers up to 700 litres of hot water at 40°C, the highest hot water capacity in the Elve range.

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.
