Using dynamic electricity tariffs for heating

HEA•THOR heating element and my-PV DTO software save up to 35 per cent of electricity costs

Thanks to the new HEA•THOR heating element and the heat optimiser for dynamic  electricity tariffs – the my-PV DTO – households can use renewable electricity for  hot water and heating at an optimised price. The photovoltaic heating expert my PV will be presenting the new products for the first time at the ISH trade fair in  March and at Intersolar Europe in May. 

Price-optimised hot water generation 

With the my-PV DTO (which stands for Dynamic Tariff Optimiser), anyone who has a dynamic  electricity tariff can benefit from renewable and affordable energy. my-PV integrated the  feature, which contains exchange market prices from 13 European countries, into its my-PV  Cloud in March. By analysing individual user habits and technical parameters, my-PV DTO  determines the best time for the heat supply based on the current exchange electricity prices.  Users do not have to keep an eye on current prices because the system controls the heat  generation fully automatically and activates the heating element in the boiler precisely when  electricity prices are at their lowest. Commissioning in the my-PV Cloud is extremely simple  and all operating data can be called up at any time.  

With the my-PV DTO, users can save up to 35 per cent of their electricity costs“, says my-PV  Managing Director Dr Gerhard Rimpler. The feature works with all IoT-enabled my-PV devices:  AC ELWA 2, AC•THOR, AC•THOR 9s and SOL•THOR. In combination with a photovoltaic  system, the optimiser predicts the PV yield for the next day based on weather data and  supplies users with inexpensive energy from the grid if the PV system is not supplying enough  power due to bad weather or at night, for example.

Benefit even without your own PV system 

Households without their own PV system can also benefit from price-optimised renewable  energy in combination with the new HEA•THOR IoT heating element. The photovoltaic heating  specialist my-PV is launching two versions of the device on the European market in the third  quarter of 2025. While the single-phase version has an output of 3.5 kW, my-PV has designed  the three-phase version for heating outputs of 9 kW. 

The HEA-THOR can be installed in both hot water and buffer storage tanks. It is connected to  the my-PV Cloud via LAN/WLAN. The HEA•THOR can be used with Ethernet RJ45, WLAN  and RS485 as communication options. In conjunction with the HEA-THOR, the my-PV DTO  provides users of dynamic electricity tariffs with a decisive opportunity to save costs in electrical  heat generation. In addition, the HEA•THOR can also be controlled via the my-PV Cloud API  or Modbus TCP / RTU to control via the DTO.

On show at leading trade fairs 

my-PV will be presenting its new products for the first time from 17 to 21 March at ISH, the  world’s leading trade fair for for HVAC + water, in Frankfurt. Visitors will find the company in  Hall 12.1, Stand B91. From 7 to 9 May, my-PV will be presenting its solutions at the stand of  its partner KOSTAL Solar Electric at the world’s leading trade fair for the solar industry,  Intersolar Europe in Munich in Hall B3, Stand 130. The photovoltaic heating specialist will be  offering journalists individual press conferences at both trade fairs.
