At MEINS, we continue advancing in sustainable energy solutions, and we are pleased to introduce one of our latest innovations: THAWI, our instant thermal generation system.
THAWI directly transforms solar photovoltaic energy into heat, producing hot water efficiently and without relying on the electrical grid. Available in 40 kW, 60 kW, 80 kW, and 100 kW capacities, it reaches temperatures of up to 92 °C and a flow rate of up to 4.4 m³/h.

How does it work?
The system preheats the return circuit water before it enters the conventional boiler, reducing fuel consumption and contributing to the decarbonization of the facilities. Its isolated DC photothermal technology converts solar energy directly into heat with an efficiency of up to 99%.
Advantages of THAWI
- Thermal generation using 100% solar energy.
- High outlet temperature: +92 °C.
- Robust and protected system (IP54).
- Ultra-fast temperature control in 500 ms.
- Completely independent from the electrical grid.
- Converts variable costs into fixed costs over 25 years.
- Possibility of sharing the same photovoltaic plant for simultaneous electricity generation.
