New immersion heater controller: controlling Power to Heat

Country of Origin: Germany
Reference Number: TODE20170918001
Publication Date: 17 October 2017

Summary

A German company has developed a new immersion heater controller for converting electricity produced e.g. by a photovoltaic system into heat. This solution allows a better controll and access of renewable energies for the own consumption by the producer.
Partners for a commercial agreement with technical assistance are sought.

Description

A German company has developed a new immersion heater controller for converting electricity produced e.g. by a photovoltaic system into heat. 

In our days the problem is that photovoltaic systems produce energy mainly for the public grid and it is difficult to controll the use of the produced enery for the own consumption.

The immersion heater controller detects excess current, e.g. produced by photovoltaic systems (PV), calculates the energy available and redirects it to an electric heater. Thus, excess PV current can be directly converted into thermal energy and stored. By means of a data-logger or the communication module, the self-generated current can be visualised via an Internet portal.

How it works: the PV system produces energy while the sun is shining. The energy produced is used as household power, e.g. demostic or elctrical appliances. The controller redirects the the excess energy to an electric heater for heating the store. When the store is loaded, the surplus energy can be fed into the public grid.

So owners of a PV system has that syste the advantage they have lower heating costs. Also they are independet from the energy market and have more reductions of CO2 emissions.rend
The systems allows the optimations of a PV system, so that first the own consumption is covered.

Partners for a commercial agreement with technical assistance are sought. This could be system vendors from sanitary, photovoltaic, heating or electronics.

Advantages and Innovations

- Using excess current for heating a water store
- Electric heater of up to 3 kW, variable and grid compliant
- Direct control of the electric immersion heater in the store
- Can be fitted to all stores equipped with an electric immersion heater
- Reliable household power priority
- Economical solution for using excess current

Stage Of Development

Requested partner

The implemetation of the technology in existing energy systems needs a technical understanding. This could be system vendors from sanitary, photovoltaic, heating or electronics. A technical understanding of eclectronics and/or hydraulics and an own technical service is necessary.
