Heat pumps

The heating revolution is here: R290 Heat Pumps from SOLE SA - Smart Grid Ready


SOLE SA pioneers once again, introducing the new generation of monoblock heat pumps with the new refrigerant R290.

In an era where energy efficiency, sustainability and safety are top priorities, SOLE SA pioneers once again, introducing the new generation of monobloc heat pumps with the new R290 refrigerant.



R290 – The future of refrigerants

R290 (propane) is a natural, non-toxic refrigerant with zero Ozone Depletion Potential (ODP=0) and extremely low Global Warming Potential (GWP=3), making it the most ecological choice for modern thermohydraulic installations.


SOLE SA heat pumps utilize this environmentally friendly medium with high thermal exchange efficiency, offering maximum energy efficiency and low operating costs.

Safe use of R290 with multiple protection system

SOLE SA has incorporated an advanced safety system specifically designed for the use of R290, which includes:

  • Refrigerant leak detection,
  • Automatic operation lock in case of destabilization,
  • Automatic ventilation system with a deaerator which, in the event of a failure, redirects the gas outside the home,
  • Specially constructed, hermetically sealed housing of the electrical components,
  • Automatic user notification in case of failure.

End-user security is a top priority for SOLE.

Impressive performance and energy efficiency

SOLE SA's R290 heat pumps stand out for their high performance:

  • Maximum water temperature up to 75°C, suitable for demanding heating and hot water systems,
  • Energy class A+++ at 35°C and A++ at 55°C according to ErP,
  • High COP (up to 5.62) and SCOP (up to 4.69), ensuring excellent economy,
  • DC Inverter technology for precise control and energy savings of up to 50% compared to old-style ON/OFF compressors and up to 75% compared to old-style oil boilers,
  • Support for operation at extreme external temperatures: -15°C hot water output of 70°C and uninterrupted system operation even at -25°C.

Smart management and connectivity

Each unit is equipped with a built-in Wi-Fi module, enabling management via an IoT cloud platform with remote control, while supporting multiple languages for the convenience of the end user.


In addition, the series supports Smart Grid functions, allowing cooperation with Photovoltaic and energy storage systems.

Hygienic use and installation flexibility

SOLE SA heat pumps feature programmable high-temperature disinfection of hot water to eliminate bacteria (e.g. legionella) and support for connecting up to 8 units in cascade mode, ideal for larger applications.


They are suitable for both heating and cooling, as well as for the production of hot water (DHW), making them an ideal solution for both residences, hotels and professional buildings with increased requirements.
