At PowerNight, we sell environmentally friendly heating systems for a more sustainable energy consumption.

The reason why the electricity bill sometimes skyrocket is that we usually pick up electricity during the day, where it is the most expensive. Electricity is actually quite cheap at night, but since it has always been a challenge to store electricity, very few people have been able to take advantage of this fact. A PowerNight system not only manages to pick up the cheap power by itself, but also to store it internally and save it for later use. On top of this, the process is 100% CO2-neutral, so your company can keep up with the green transition while saving massively on your electricity bill.

All our systems are all based on the same basic vision, with minor variations, depending on the type of model used. What they all have in common, however, is that they are based on heat storage consisting of a system of magnesium bricks.
