An eco-friendly spring

Spring is the time to renovate! Discover our sustainable solutions and save water, energy and money.

The hydrophore pump

The average Belgian consumes 96 liters of drinking water a day, most of which is used for cleaning and maintenance, and only 5% for food. Saving this blue gold is more important than ever, so rainwater harvesting is essential. As a result, it's becoming increasingly common to install rainwater harvesting systems in the home, and depending on the region, even compulsory. It's used for watering the garden, cleaning, washing clothes or flushing the toilet.

Rainwater harvesting

The D ventilation system

No more hibernation: all our senses reopen in spring! And so do our windows, even if the weather and temperatures sometimes play tricks on us... So you still need to heat your home at certain times. Of course, you'll heat less if you insulate your roofs, façades, floors, windows and doors properly. But you can make sure that every kWh of energy is put to better use... For example, your boiler will run less with double-flow ventilation (or system D). This system recovers 90% of the heat in your home to preheat the air drawn from outside. The result: healthier air in every room, fewer CO2 emissions, and more backup for your fossil-fuel heating system.

Which ventilation system to choose?

The solar collector and solar water heater

Solar collectors work in conjunction with a solar water heater to convert heat from the sun into hot water.


Filtration of rainwater

Rainwater filters remove impurities, dirt, discoloration and unwanted odors. Your filtered rainwater is perfect for use in washing machines, toilets,...


The smart thermostat

Even the little things shouldn't leave you cold this winter: smart home solutions like a connected thermostat and thermostatic faucets ensure that you can heat exactly where and when you need to.

Renewable energy

The air, the sun and the earth energise your home! The calories still present in the air or the earth are captured by heat pumps and released into your radiators. The same goes for the hot water in your showers with a thermodynamic water heater. In short, a heat pump can do everything your boiler can! Lead the way. Break away from fossil fuels and enjoy a comfortable warmth.

Sustainable heating

Less energy for the same feeling of warmth! With underfloor heating and low-temperature radiators, you're already saving over 10%!


Ventilation ensures a healthy indoor climate, while being energy efficient. It can recover up to 90% of the warmth in the home, while providing healthy air! Eliminate unpleasant odours, water vapour and saturated air by precisely managing air renewal. 

Rainwater harvesting

60% of your water needs can be met by rainwater! You can use it for the toilet, washing, watering plants, etc. You collect rainwater in a cistern and use it later with a pump, anti-dirt filters and a dedicated water circuit. What are you waiting for?

Water treatment

Softer tap water will benefit the longevity of your sanitary installations and your energy consumption. With a water softener, you can prevent energy-consuming and harmful scaling of pipes and many appliances. Did you know that 1 mm of limescale increases energy consumption by 10%?

Smart home

Electronics provide a major boost: smart home solutions such as connected thermostats and connected valves allow you to heat precisely where and when you need to. The same goes for your hot water when you're on holiday: with a connected water heater, you can activate the absence mode remotely and avoid wasting energy!
