Using dynamic electricity tariffs for heat without your own photovoltaic system

HEA•THOR

HEA•THOR enables the efficient use of dynamic electricity tariffs for heating. Even households without their own photovoltaic system can benefit from affordable, renewable energy with HEA•THOR – in combination with my-PV DTO, the latest feature of the my-PV Cloud, which optimizes heating costs.

As a network-enabled heating element, the HEA•THOR is available in 3.5 kW and 9 kW power options. The my-PV DTO can be easily activated in the my-PV Cloud and automatically controls HEA•THOR via LAN or Wi-Fi to utilize the lowest-cost electricity tariffs. In addition to the my-PV DTO, water heating with HEA•THOR can also be controlled via the my-PV API as well as via Modbus TCP or RTU.

Thanks to the integrated temperature display, operation is especially convenient: the current water temperature can be read and adjusted directly on the device, while all operating data is accessible at any time in the my-PV Cloud.

Advantages of HEA•THOR

  • Benefit from low-cost, renewable energy even without your own PV system

  • Maximum convenience: my-PV DTO fully automates water heating at the lowest-cost times

  • Network-enabled heating element, without power modulation

  • Easy installation

  • Simple operation with an integrated temperature display

  • Multiple communication options: Ethernet RJ45, Wi-Fi, RS485, potential-free switching output

  • Certified for use in domestic and potable water applications (buffer and hot water storage)

  • Ideal for decentralized heating in residential buildings

  • All operating data available at any time in the my-PV Cloud

HEA•THOR for hot water

The HEA•THOR connects to the router via LAN cable or wirelessly via Wi-Fi.

Water heating can be controlled via:

  • my-PV DTO, which optimizes dynamic electricity tariffs for heat

  • my-PV API

  • Network or Wi-Fi (Modbus TCP)

The HEA•THOR can be installed in fresh water and buffer storage tanks. Its special design results in very low thermal surface loads on the heating elements, which directly contributes to an extended product lifespan.

Dynamic Tariff Optimizer

my-PV DTO

With the new my-PV Cloud feature, the my-PV DTO (Dynamic Tariff Optimizer), anyone can benefit from affordable, renewable energy. The my-PV DTO optimizes the use of dynamic electricity tariffs specifically for water heating and space heating by activating the my-PV solutions precisely when electricity prices are at their lowest.

Activation is simple and requires just a few clicks in the my-PV Cloud. Currently, my-PV DTO is available in 13 countries, including Germany, Austria, Switzerland, the Netherlands, Belgium, Spain, France, Italy, Sweden, Norway, Denmark, Finland, and Ireland. For users, this means maximum convenience – there’s no need to constantly monitor electricity prices. The my-PV DTO fully automates heating control, always selecting the cheapest time slots. This significantly reduces heating and hot water costs compared to conventional fixed-rate electricity tariffs.
