Think about today and tomorrow

“Customers often think that investing in an energy-smart boiler room is not yet profitable. They are very surprised when they learn how much and how quickly they can save, and thus earn back the investment in the short term”, says Kris Stappers, Sales Director @ Callens.

Solutions tailored to your company – new or modular system

Switching to an alternative energy source for your steam, thermal oil or central heating boiler doesn’t have to be radical. This switch is different for each company and each context. Companies with relatively low energy consumption and a low energy capacity, both on site as well as from the surroundings, are best served by a hybrid boiler. Hybrid boilers run approximately 20% of the time on electricity and the rest of the time on natural gas. However, we determine the perfect balance in the design phase, based on current facts and future predictions.

Want to make the switch, but spread out the sustainability investments? Anything’s possible. We prepare your installation for the future and spread further CO2-reducing adaptations over the time your company needs.

Callens is a pioneer in Belgium in the field of alternative energy installations

Callens was the first to start up a hydrogen-powered steam installation in 2022. Vynova in Tessenderlo is the happy owner of the installation and benefits from 30 tonnes of CO2-neutral steam per hour each day. And we’ll be increasing this yield by the same amount again in 2023.

Our R&D team developed this innovation in-house. The design of a hydrogen-powered steam installation requires very specific technical measures. The hydrogen flame and the associated combustion values, for example, behave differently than with gas-fired boilers. Higher NOx values also require attention. We reduce these to the absolute minimum thanks to the high-tech Optimum by Callensthermal oxidizers.

Complete peace of mind: Advice, engineering, installation and service

EcologiCal thinking requires tailor-made advice. We make a proposal based on the heat you need, the fuels you have available and the sustainable direction you want to take. Our design engineers then get to work on engineering your own energy-efficient showpiece. Our technicians also take care of the subsequent installation and lifetime service, with an eye for a high-quality finish and long-lasting top performance.

EcologiCal - Frequently asked questions

Is it interesting at this time to initiate and/or implement EcologiCal thinking?

Absolutely. Switching to an alternative energy source for your steam, thermal oil or central heating boiler doesn’t have to be radical. This switch is different for each company and each context. You do it at your own pace and according to your own possibilities to be climate neutral by 2050, as required by law.

Emission rights are becoming scarcer and more expensive, making it smart to invest now in sustainable energy production. Moreover, all are subject to CO2 taxes, with these rates also increasing. We always include applicable and possible future regulations when calculating the correct, most sustainable solution.

Can I partially switch to alternative fuel with Callens or do I have to fully switch to electricity/hydrogen immediately?

We can even help those who, for whatever reason, are not yet ready to make the switch to a completely new boiler room. We then gradually replace the boilers and peripheral equipment, and foresee the connections necessary for future adaptations. After all, it’s never too early to think about where your energy policy should be headed.

Is it complex to make an existing boiler room more sustainable?

That depends on the condition of the boiler room and the sustainability trajectory still to be completed. Sometimes minor interventions are enough to reduce your CO2 emissions, but we also need to check whether they will suffice in the future. In other cases, a new boiler room is better, both economically and ecologically. Request your personalised calculation now and receive a first estimate of your sustainability trajectory.

Will alternative energy become the norm for industrial boilers?

The climate targets for 2050 are clear: a CO2-neutral energy policy. Alternative energy therefore becomes a must. The European Emission Trade System (EU ETS) is one of the levers we can use to achieve CO2 neutrality. However, emission rights are becoming scarcer and more expensive, making it smart to invest now in sustainable energy production. Moreover, all are subject to CO2 taxes, with these rates also increasing. We always include applicable and possible future regulations when calculating the correct, most sustainable solution.
