French electrician invents solar and geothermal heating system to cut his bill by three times
A French electrician’s invention makes it possible to couple solar panels to a geothermal heat pump to reduce your bill by three times.
Twelve years ago, Roger Dolmazon invented a junction box linking a heat pump to solar photovoltaic panels.
The French electrician’s invention could help the world. Roger Dolmazon won a medal at the Lépine international competition with his invention, which is a junction box that allows coupling photovoltaic panels to a geothermal heat pump.

He then launched himself onto the international scene with his invention. He already received a prize in Strasbourg, during the European Lépine competition.
How it works.
When he invented his switch cabinet, people thought he was crazy. Besides, he has been using it for 25 years to heat himself.
In 2010, when fuel prices reached record highs, the electrician’s invention began to arouse interest, as it would enable him to make significant savings. He filed a French patent, followed by a European patent the following year.
In 2013, consecration came with awards won in various innovation competitions. At that time, he was selling his ingenuity all over the world. It cost 4,500 euros and was connected by a professional plumber. His cabinet could be adapted to any heat pump. The invention was christened “La Sybérienne”.
This geothermal heating system makes it possible to couple thermal energy (heat pump) and solar energy, and thus to heat without any energy input, autonomously.
The coupling system is managed by an electronic regulation and ensures the connection between the solar collectors and the heat pump.

The system already exists in the buffer tanks, but this one is more elaborate. The system is connected to an electronically controlled coupling cabinet that is activated according to the need for heat and the temperatures of the system components.
Four modes are possible.
The system can operate in classic geothermal mode, in which case the heat pump uses the buried surface collector to produce heat. It can also operate in solar-only mode with the solar collectors.
The third possibility is called “geosolar”, and the heat pump then receives energy directly from the solar collectors.
Finally, it has a storage mode, which allows it to discharge the solar collectors directly into the ground through the buried collector.

“Thanks to my system, I have reduced my bill three times,” the inventor proudly explained.
The inventor believes that he has achieved significant energy savings with his innovative system, and that it also allows the system to be more efficient, because the water heated by the sun is at a higher temperature than the water normally used by the pump. Then, when temperatures are mild, the junction box ensures 100% solar heating, without any energy consumption. It should be noted that this invention dates back to 2009, and we have not found any recent news about its commercialization.
