"A latest generation, high-output gas boiler is reserved exclusively for domestic hot water"

Between 2006 and 2008, the Foyer Anderlechtois carried out a huge renovation project on a building in the area of the rue des Droits de l'Homme. During the works, the Foyer Anderlechtois paid special attention to managing the building's domestic hot water. Sami Naouar, the engineer in charge of Energy, details the various hot water aspects of the renovation project:

"We installed twenty thermal solar panels to preheat the water. These panels suffice in summer to meet the tenants' demand and maintain the hot water at a sufficient temperature. This was virtually the case in 2014. >A latest generation, high-output gas boiler can also take over whenever necessary. This is reserved exclusively for domestic hot water. As in fact we have chosen to have two separate systems: heating and domestic hot water. This means that we can monitor consumption accurately. And its related costs."

The managers have also emphasised servicing, with advanced maintenance of each key component: hot water storage cylinders, circulators and control of the installation.
"Here also we have been able to make significant savings in energy consumption. Finally, at night, we reduce the water circulation temperature slightly (58 to 53°C) during off-peak hours, between midnight and 5 a.m. This doesn’t inconvenience the users but consumption really does drop."

And less consumption means less charges for the tenants!
