Clean recycled waste heat
Enerin VP Software Engineering, Gunnar Vartdal, on the stage at Hannover pitching the case for recycling waste heat.
In April 2024, nearly a year ago, Enerin took the stage at the Hannover Exhibition in Germany, where Norway was the official partner country. At the event, Enerin VP Software Engineering, Gunnar Vartdal, pitched our HoegTemp heat pumps, highlighting how intelligent waste heat recycling can reduce energy consumption by up to 70%.
A year later, this message is more relevant than ever. The need for smarter, sustainable energy solutions continues to grow, and we remain at the forefront of helping industries turn waste heat into value. Since then, there have been many exciting developments—but our core message to industry remains the same.
This is what Gunnar said:
“24% of the world’s CO2 emissions, come from industrial heating. The phones you use, the food you eat, and the chairs you sit on all come from factories that require heat in some form. Most of these factories burn fossil fuels to produce the heat. And after they have used the heat to produce food and goods, they dump the leftover heat, also called waste heat, into the air as steam.
What if I told you that we can capture the leftover heat and at the same time replace the fossil fuels that are burned for heating, allowing us to produce clean recycled industrial heat?
At Enerin, we have developed a world leading industrial heat pump capable of delivering heat at temperatures up to 250 degrees Celsius (482 degrees Fahrenheit). You can connect any heat source to it, such as the waste heat from factories, or from the outside air, and reuse that heat in many ways for factory processing needs – such as steam, hot water, or thermal oil to dry or fry food.
Our industrial heat pump is extremely robust to changes in operating conditions, handling large rapid changes with ease, so that it can immediately replace existing heating solutions.
“The HoegTemp can stop and restart in seconds, regaining full power in minutes. This makes it ideal for managing power loads within manufacturing environments and for electrical grid administrators.”

Integrating our stand-alone, modular heat pumps offer a quick factory retrofit without having to make major changes to the existing steam supply system. Usually, large-scale heat pumps are engineered into a particular factory process which can be costly. Because of this they can pose future suitability and cost risks for factories when associated equipment and technology upgrades are made on the factory floor.
Our heat pumps need a connection to steam, water and electricity. This makes them future proof. The HoegTemp will work equally well at high temperature lifts, as at low temperature lifts, and will not require modifications if the plant’s needs change in the future.
We have also developed a combination of sensors and software solutions to quickly analyse and optimise heat flows and the recycling of waste heat in factories.
“And if our heat pumps are used together with the intelligent recycling of waste heat, we have in many cases found it possible to reduce energy consumption by as much as 70%. This makes it possible for factory owners to both eliminate their carbon emissions and save money at the same time.”
Many large companies have the goal of becoming carbon neutral by 2030 or 2035, and they see industrial heat pumps such as ours as a key technology enabling them to reach their goals. Our main challenge is to scale up the production of our heat pumps to meet the large customer demand and to provide energy at a competitive price to fossil fuels.
We have purposely designed our heat pump to be very similar to a large V6 diesel engine, although it runs on electricity. We use standard automotive suppliers for most of the heat pump’s parts which results in easy maintenance that can be carried out by mechanics.
Enerin believes that by using quality German and European automotive engineering components for its HTHPs, coupled with an innovative heat pump design, the company could contribute substantially to the five per cent segment of the global energy market used for industrial heating up to 200°C. If our heat pumps were deployed rapidly, the health of the automotive sector would also benefit.
Join us on our mission to eliminate pollution from industrial heating.
Thank you.”
As we reflect on our journey since Hannover we are pleased to report that we are currently on our third HTHP installation at Pelagia which has been covered recently in Forbes.
Do not let your valuable waste heat disappear into the air. We can recover and repurpose it to improve energy efficiency, lower costs, and reduce emissions. Industrial heat recovery is shaping the future of energy efficiency by creating jobs and economic growth.
