Roth wall console PTH

the optimal storage of PV surplus power

PV surplus power - energy-efficient auxiliary heating with solar energy

Owners of PV systems can use self-generated, surplus electricity to heat buffer or drinking water storage tanks. The Roth PTH wall console is particularly suitable for systems whose subsidy (feed-in tariff) is coming to an end. It is designed for easy direct mounting to the storage tank to generate energy-efficient turbulence-free high-temperature stratification.

The high temperatures ensure comprehensive legionella protection. The external heating element can add heat up to a maximum storage tank temperature of 85 °C. The heating element is available in power ratings up to 3.5 kW (PV IOT 0 - 10 V, 400 V, 7-stage). The basic version of the Roth PTH wall console consists of a console rear panel, the hydraulic unit and the insulation housing. An electrical connection box is also available. This is prepared for a customer's own energy management system and can be selected according to size requirements. The system can be controlled via an app.
