TESTIMONIALS

What our customers say

Installation of an Ilusmart: installation went smoothly and quickly with the necessary explanation. They kept their appointment. Clear app to monitor injection and withdrawal. Satisfied!

Koen Van Brusselen

Everything nicely installed, my panels inspected and coated! ...and now just waiting to see if the newly installed PIDbox improves the efficiency of my panels.

Jos Martens

Perfect collaboration with experienced staff. Service as it should be.

Jos Janssens

Thanks to your site, I can see if my installation is returning to how it was at the beginning, or what percentage I recover by applying the PID-BOX principle.

Luc Cuvelier

After years of paying too much for energy, finally a system that works for me. The technicians knew exactly what they were doing and explained everything clearly. The app is highly recommended!

Fleur van den Broek

They responded quickly to my request, and the installation was arranged within a week. My panels are now running at full capacity thanks to the PIDbox. I should have done this sooner.

Sander Vermeer

Friendly technicians who really know what they are doing. Installation completed neatly, no mess left behind. Via the app, I can now see live how much I produce and inject. Great!

Noor Bakker

My old panels had been producing less than expected for years. After the coating and the PIDbox installation, I notice the difference immediately. The system now monitors itself — handy!

Joris Hoekstra

Professional from start to finish. Appointment kept punctually, installation went smoothly, and the Ilusmart app works intuitively. Finally, I have a grip on my own energy consumption.

Roos van Dijk

Good communication before, during, and after the installation. The technician took the time to show everything via the app. Small investment, but the difference in return is already visible after one month.

FAQs

Frequently asked questions
about heat pump boilers

Can I combine a heat pump boiler with solar panels?

Absolutely. In combination with solar panels, Heatwave runs entirely on self-produced energy. This makes your water heating CO₂-neutral.

Does a heat pump boiler make a lot of noise?

No. Heatwave is designed for quiet operation. You can therefore feel free to install it anywhere in your home.

What size should the storage tank be?

That depends on your consumption. For a family of up to 4 people, 200 liters is usually sufficient. If you have a larger family or multiple bathrooms, 300 liters is recommended.

Does a heat pump boiler also work in winter?

Yes. Heatwave extracts heat from the ambient air and functions perfectly in cold temperatures. Even in an unheated garage, the efficiency remains high.
