Case Study: Electricool on the transition to a gas-free home

In the Wallonia region, installation company Electricool helped a family drastically reduce their dependence on fossil fuels. Through a well-thought-out combination of solar energy, a hybrid inverter, and a heat pump, an annual energy saving of up to €1,600 was achieved.

The Situation: High costs, low autonomy

The home, occupied by a family with one child, relied entirely on gas for both heating and hot water. With an annual bill of approximately €2,400, the customer's wish was clear: energy costs had to go down and living comfort had to go up, especially during the warm summer months.

Electricool analyzed the consumption and the budget and developed an integrated plan to make the home more sustainable without losing sight of financial feasibility.

The Technical Solution: Maximizing yield and self-consumption

Within a single day, the Electricool team installed a complete system:

• 14 solar panels (6.3 kWp): Installed in an East-West orientation. This choice ensures a flatter but longer energy yield throughout the day, which is ideal for direct self-consumption.

• Growatt 5 kW hybrid inverter: This forms the heart of the installation and manages energy flows efficiently.

• LG air-to-air heat pump (5 kW): A reversible unit that heats the living room in winter and cools it in summer.

• Electric boiler: A smart addition to directly convert surplus solar energy into hot water, instead of feeding it back into the grid at a low rate.
