This is us
Experts with a wide range of specializations—from energy technology/thermodynamics to urban planning, computational science, meteorology, and international management. Diversified expertise that helps us find the right solutions for every project situation.
Our Passion
With our passion for renewable energies, we want to shape the future and make a difference. We love what we do and look forward to every project we are privileged to be involved in.
Our Mission
The Theta brand stands for sustainable supply concepts: climate-neutral, secure and socially responsible. The focus is on identifying and designing the most economically and technically viable supply options.
We do not design perpetual motion machines. Our concepts are based on energy flows, temperature levels, and efficiency chains.
Our Task
The transformation process from fossil to renewable heat offers a variety of technologies and application paths – from central supply, to local and district heating based on waste heat, large heat pumps, and energy storage, to decentralized concepts using air and geothermal heat, and even green hydrogen and its derivatives methanol and ammonia.
We are technology-neutral and independent. We support you with your heat plan, your transformation process, or your feasibility study with well-thought-out concepts. The identification of the most economical and technologically sensible supply option is our primary focus.
