Investing in renewable energy technologies

Renewable energy technologies are high on the agenda of homeowners who not only want to save money, but also reduce their carbon footprint. Energy upgrades to your home can not only significantly reduce energy bills, but also increase the value of your home and help protect the environment. In this article, we will look at the prices and premiums of some of the most popular investments to make your home more sustainable.

Heat pumps are the heating systems of the future, and there are several types on the market. Air-to-air heat pumps work like reverse air conditioners, while air-to-water heat pumps draw heat from the outside air to heat both your home and your plumbing. Geothermal heat pumps draw heat from underground. Costs vary depending on the type and power of the heat pump.

• Guide price: Geothermal heat pumps cost between 12,500 and 22,000 euros, air-water heat pumps between 8,000 and 14,000 euros, air-to-air heat pumps between 6,000 and 10,000 euros, and hybrid systems start at 10,050 euros.
• Payback Period: The payback period for a heat pump can exceed 15 years, mainly because of high electricity prices. It is important to invest in insulation first and consider solar panels to shorten the payback period.
• Premium: The My Renovation Premium is available, where you can claim back up to 50% of the energy bill, depending on your income category.

A heat pump water heater uses heat from various sources, such as a solar water heater, heat pump, boiler, solar panels, or ventilation system, to heat water for domestic use. It uses much less energy than an electric water heater.

• Guide price: The price ranges from 2,500 to 3,500 euros, including VAT, but excluding installation costs and accessories.

• Premium: The My Rebuilding Premium can be up to 50% of the bill, depending on your income category.

Solar panels are a well-known way to generate green energy. Costs vary depending on the consumption of your family and home.

• Guide price: For an average family consuming 3,500 kWh per year, a 4,000 Wp installation costs about 4,800 euros, excluding VAT.
• Payback: The payback period depends on several factors, but on average you can recoup the investment in three years.
• Premium: Fluvius offers premiums for solar panels ranging from 150 euros/kWp to 75 euros/kWp, depending on the year.

Home batteries are interesting for storing self-generated solar energy for use in the evening and at night, especially with the elimination of the reverse counter.

• Guide price: A 10 kWh home battery costs about 9,000 euros, which is significantly lower than a few years ago.
• Payback: The payback period for a home battery varies between 6 and 16 years, depending on your situation and the price of energy.
• Premium: Premiums for home batteries were available until March 31, 2023.
