Solar Flat Plate CollectorauroTHERM VFK 145/3 V/H
Reliable solar energy for hot water production.
- Collect the sun’s free energy
- Installation tailored to any context
- Durable construction for long-lasting performance
- Seamless integration into Vaillant solar systems
The auroTHERM VFK 145 solar thermal flat plate collector is an ideal and cost-effective way to start using solar energy. Suitable for pressurised solar systems, it can cover 70% or more of your domestic hot water needs for free, depending on regional sunlight levels. Its sleek, flat design with robust structural glass allows 91% of solar energy to pass through, while its side insulation ensures highly efficient heat transfer. The collectors can be installed vertically or horizontally, raised on the roof or fully integrated into it, on pitched roofs or terraces — always using reliable, dedicated mounting systems. Multiple auroTHERM VFK 145 collectors can also be connected to meet higher hot water demands.
Ideal for:
- Heating
- Hot water
