Heat from electricity with the Max-Heater F12 PV heating device

Making sensible use of surplus electricity

The PV Max-Heater F12 was developed, among other things, for the use of surplus electricity from natural power plants, e.g., PV systems in private households, and represents a real alternative to EEG remuneration.

The advantages of the PV Max-Heater at a glance:

  • Direct heating support and hot water production using surplus energy from natural electricity generated on site
  • Economic use and storage of natural energy outside the EEG
  • More revenue from expiring grid feed-in contracts
  • Quick and easy retrofitting in existing buildings
  • Voreinstellbare Vorlauftemperatur für sofortigen Nutzen der Energie
  • Can also be used as an emergency heat generator (mains power supply)

Use of surplus electricity

The system’s current meter reliably measures excess electricity and determines the actual amount of surplus energy available (after deducting all internal consumers, which have priority). This energy is forwarded to the continuously variable device (up to 12 kW) and used to heat the hydraulically integrated heat storage tank for later use in heating and domestic hot water. In this way, the excess power from the PV system is converted into heat energy and stored as renewable energy.

The intelligent control increases the consumption of renewable electricity and reduces the costs for conventional generation. The main difference to simple heating elements is that the temperature level can be precisely adjusted via the speed-controlled pump, ensuring that only usable heat is produced at the required temperature level.

PV Max-Heater F12 devices are designed to use excess electricity from newly installed photovoltaic systems for heating and hot water production (e.g., in private households). The intelligent ratiotherm PV Max-Heater technology can also be an interesting addition for old PV systems with high feed-in tariffs that are currently operating at full capacity and are due to expire under the Renewable Energy Sources Act (EEG).

Possible implementation variants for PV Max-Heater F12:

  • Excess electricity in private households used for domestic consumption to generate hot water
  • Use of surplus electricity from inverters capped by the energy supply company
  • Combination of battery storage and PV Max-Heater >> Interfaces
  • PV Max-Heater F12 can also be used as a sole or (emergency) heat generator.
