INVENTA ENERGY aims to manufacture, sell, and install in greenhouses, a new heating system for greenhouse plants with own know-how, protected by international patents, (Figure 1). The system heats plants with infrared (long wavelength), safe for humans and animals. It is cheaper than indoor conventional hot water or hot air heating systems and offers energy savings of up to 65% compared to such conventional heating systems.

The main component of the heating system is the low temperature “heated curtains”. When the temperature of the plants drops below a desired value, the heated curtains are extended (deployed) with an electromechanical system and completely cover the plants and deliver the required energy to the plants with infrared radiation (long wavelength). When the plants do not need additional energy then the heated curtains are withdrawn (retracted), (Figure 2). The curtains are made of polymeric materials, transparent to solar radiation and are heated through ducts (channels) passing hot air or through electrical ducts with electricity drainage. The operation of the system is automatically controlled with special software and sensors for non-contact detection of plant temperature.

The team members of our company have many years of experience in research & development on renewable energy and energy efficiency technologies. We are open for collaboration with research institutions and private entities towards achieving our objective and promoting in the international market our innovative radiant heating system as also to developing and implementing new sustainable energy systems and contribute to the reduction of fossil fuels and mitigate climate change.


The heating system is new, innovative, not manufactured or marketed by any other manufacturer or supplier. The system is in the patenting phase with international patent application (WIPO/PCT WO2023 094843 A1 and EPO 22000254.7 – 1105/4186352). The innovations and advantages of the new system are:

  1. Direct heating of the greenhouse plants, not the greenhouse air, through the low temperature heated curtains.
  2. Use of special software to control the operation of the system with sensors for non-contact detection of the temperature and vigour of the plants.
  3. Energy savings, compared to conventional commercially available greenhouse air heating systems, up to 65%.
  4. Possibility of using renewable energy sources.
  5. Significantly lower purchase and installation costs compared to existing commercially available greenhouse air heating systems.
  6. Possibility of application in vertical cultivation systems in closed spaces with a fully adjustable microclimate.
  7. Prospects for space (non-terrestrial) applications for temperature control of plant growth and food production in space (off earth) because our system does not use air as a means of heating plants.
