New or modular: choose a solution that suits your company/context

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 and 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.

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 projects and news

With the launch of the very first hydrogen-based steam system in 2022, Callens is the pioneer in the field of alternative energy installations in Belgium. All our innovations are designed in-house by our imaginative Department of Technology. Check out our most recently completed projects and the latest news here.  

EcologiCal - Frequently asked questions

When will the switch to EcologiCal thinking/solutions become a must?

As of now! Making the switch takes time, especially if you have specific investments in mind and also expect a return. Start with a CO2 roadmap now to cross-check your options against your needs so that you know where to start and which (phased) investments you will have to make when to reach the 2050 targets, and to get the best return on your investment.

Most ecological solutions are paying off handsomely already. Examples that spring to mind are the hybrid steam boilers that capitalise on your grid balance, waste flows you can valorise or self-generated electricity to produce your own heat cheaply.

Emission rights are becoming scarcer and more expensive, which makes it a smart move to invest in sustainable energy production now. What’s more, there’s no escaping the ever-increasing COtaxes. We always factor in the applicable and possible future regulations when calculating the correct, most sustainable solution.

Will gas as a fuel disappear from the fuel landscape altogether?

By 2030, gas will definitely not have been entirely banned. That will require more time.

Not everything can run on electricity.

Which alternative fuels will become the most attractive?

Which alternative fuels will be the most attractive to your company will depend on: 

  • whatever waste flows, like biogas, syngas and hydrogen, not to mention ethanol, methanol, LCV fuels and other hydrocarbons, you have access to
  • the amount of electric energy you can generate on-site
  • the type of energy neighbouring businesses can supply you with cheaply

We have noticed a rising trend in the use of hydrogen among companies that require high wattages. Anyone who is producing it as a waste flow, can capitalise on that already. Importing it is still too expensive and next to impossible logistically speaking. But that is sure to change in the not-too-distant future. 

Can Callens help me to make a partial switch, or do I have to go for a complete ecological solution straightaway?

Switching to an alternative energy source for your steam, thermal oil or central heating boiler doesn't have to be radical. The switch will be different for every company and in every context. You can do so at your own pace and according to your own capabilities to be climate neutral by 2050, as required by law.

We can even help those who, for whatever reason, are not ready to make the switch to a completely new boiler room yet. In that case, we gradually replace the boilers and peripheral equipment, and put the relevant connections for future adaptations in place. 

Is it a complex process to convert an existing boiler using EcologiCal technologies?

That will depend on the condition of your boiler room and the sustainability journey still ahead of you. Sometimes minor interventions are enough to reduce your COemissions, but we also need to check whether they will suffice in years to come. In other cases, a new boiler room will be the wiser choice, both economically and ecologically. 

Ask Callens for an initial assessment of the sustainability journey ahead of you.

What legislation will be coming on stream?

The 2050 climate targets 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, which makes it a smart move to invest in sustainable energy production now. What’s more, there’s no escaping the ever-increasing COtaxes. We always factor in the applicable and possible future regulations when calculating the correct, most sustainable solution.
