“ThermCube – The heat pump all-in-one heating cabinet”: 3U companies launch sales with a product presentation in a live stream

  • Significant time and cost savings for do-it-yourselfers and craftspeople
  • Innovative complete system addresses growing demand for CO2-neutral heating
  • Utility model protection granted; patent applied for
  • Important contribution to achieving climate goals

Marburg and Koblenz, 16 August 2023 – PELIA Gebäudesysteme GmbH and Selfio GmbH, subsidiaries of 3U HOLDING AG (ISIN DE0005167902), officially launched the distribution of their ThermCube (https://thermcube.de) on 16 August 2023 with a live event broadcast on YouTube. The modular, prefabricated “Heat Pump Heating Centre in a Rack” enables the quick and cost-effective installation of a complete heat pump system and thus makes it easier for homeowners to switch to CO2-neutral heating, which will soon be required by law.

According to the German Heat Pump Association (Bundesverband Wärmepumpe e.V.), more than 200,000 heat pumps were installed in Germany in 2022 alone, and a further increase in demand is expected from next year. Across Europe, the EU Heat Pump Report 2022 estimates demand at a total of 50 million heat pumps by 2030. In view of the shortage of skilled workers, a heating system that is easy and quick to install can effectively help meet this demand and sustainably reduce the use of fossil fuels.

The ThermCube revolutionises heat pump installation

The core element of the ThermCube is a climate-friendly heat pump. All standardised hydraulic modules and control units required for its operation are permanently installed, hydraulically connected, and electrically prewired. The use of the pre-assembled complete system therefore reduces the connection time of the heating system to a fraction of the previous installation time. The ThermCube also drastically reduces the time and effort required for planning, configuration and procurement by builders and craftspeople. The components and assemblies used come from well-known brand manufacturers and are subject to documented quality controls. Installation and operation of the ThermCube are usually eligible for subsidies according to the applicable subsidy guidelines.

The ThermCube is suitable for detached and semi-detached houses with a total heat requirement of 6-11 kW, both in new and existing buildings. The footprint is less than 1 sqm. It can be installed in the house by do-it-yourselfers and also by non-specialist craftspeople. Special knowledge or special tools are not required. Only for the final dismantling and commissioning a specialised company must be commissioned. The German Patent and Trademark Office has already granted utility model protection for the ThermCube. A patent application has been filed.

Craft businesses specialising in plumbing, electrical or heating construction can also procure the ThermCube from the 3U companies. The significantly lower time expenditure enables them to process more orders with the same team of skilled workers. The ThermCube facilitates work on the construction site and ensures better planning and cost control.

“Climate-friendly, CO2-neutral heating is currently one of the most discussed topics in the entire industry. With the introduction of the new cost-efficient and climate-friendly heating centres, we are making a further contribution to reducing CO2 emissions and dependence on fossil fuels such as gas and oil,” emphasises Uwe Knoke, Member of the Management Board for Strategy and Business Development at 3U HOLDING AG. “But it should also prove to be a significant driver for the planned rapid and sustainable growth in sales and earnings in our SHK segment. We expect demand to be good and tend to increase further and have already secured our market entry by prudent stocking of components and parts. With the ThermCube, we are expanding our product range with an innovative, economically interesting system and are tending to open up new market segments, such as the prefabricated house sector. The sales launch of the ThermCube is thus an important milestone in the course of our ‘MISSION 2026’.”
