De Dietrich Strateo

The STRATEO is the silent, effective heat pump solution for new buildings. It is characterised by its compact size and efficient performance: COP of up to 5.11 at an outdoor air temperature of + 7 °C.

A high-tech product with an INVERTER system with power accumulator, the STRATEO heat pump offers a more stable setpoint temperature, substantially reduced power consumption and quiet operation, generating a sound power level of just 30 dB(A) to 39 dB(A). The reversible STRATEO also operates in cooling mode via the underfloor cooling system (water at + 18 °C), and as air conditioning via convection fans (EER of 3.96 to 4.75 for an outdoor temperature of + 35 °C).

With its compact dimensions, it is easy to install thanks to its wall-mounted preassembly plate for the hydraulic connections. The hydraulic unit integrating all the elements required for the heating installation can be accessed behind the front panel, which facilitates maintenance. It includes a 190-litre DHW tank located under the indoor unit in the form of an attractive uniform column. It offers optimal comfort all year round. Its compact construction, design and simple installation mean it can be easily integrated in a new build environment.
