AC•THOR: Hot water and space heating with solar power

Water heating and building heating with photovoltaics

AC•THOR is a 0 - 3 kW linearly controlled photovoltaic power diverter for hot water, electric heat sources and optional space heating.

Simple & efficient: AC•THOR controls electrical heat sources depending on the availability of PV energy and heat demand. And that for both hot water, as well as for space heating. It ensures your personal living comfort fully automatically . In a residential building that is built or renovated according to current energy standards, AC•THOR replaces conventional, water-based building installations. Missing residual energy can be obtained from the public grid.

Of course, AC•THOR can also be integrated into conventional, water-based systems such as buffer storages. Its flexibility leaves nothing to be desired. Thanks to the built-in touch display, it can be operated without any additional devices at any time and it is easy to install.

The application video explains the benefits and versatility of AC•THOR. As the video is in German just activate the English subtitles on youtube.

AC•THOR in combination with my-PV WiFi Meter

In combination with my-PV WiFi Meter, AC•THOR uses excess energy from your photovoltaic system to supply electrical heat sources such as immersion heaters, electric heating mats or infrared panels linearly with power. This ensures optimal energy utilization.

AC•THOR in combination with battery storage

In combination with compatible batteries, AC•THOR, like AC ELWA 2, performs a hybrid storage function. Not only the hot water, but also the building mass (like in our new company building) can be used as storage. This way, even with larger PV systems, excess PV energy is optimally used. Optimal priority regulation between battery and heat storage is guaranteed. Click here for the compatible manufacturers.

AC•THOR in combination with Smart Home

Thanks to its flexible control, the AC•THOR also communicates with energy management systems. As an alternative to my-PV WiFi Meter, the excess information can also be received from these sources. Thus there are no limits for the integration into individual home controls. Data can be visualized in the Smart Home System.

Tip AC•THOR works perfectly with our immersion heater but it can also be easily used with existing heating rods.


Advantages of AC•THOR

  • 30% cost savings over conventional systems with self-generated energy

  • Maintenance-free due to cables instead of pipes

  • Reduction of the boiler room space

  • Flexible control by various inverters, battery systems and Smart Homes

  • Allows affordable housing also in apartment buildings

  • Up to 85% PV self-consumption even without battery storage
