Do you want to consume up to 11 times less electricity to produce your domestic hot water? ☝️ You've come to the right place ???????? In this video I show you all the steps for installing and connecting a De Dietrich solar water heater, model BESL 300 +1 sensor… But I don't stop there! : you will discover in this video, the real consumption of a solar water heater measured using an energy meter over almost a year of production! Then, I make a detailed and precise comparison between the following three solutions for producing domestic hot water: The electric water heater (classic cumulus) The thermodynamic water heater The solar water heater This is a non-sponsored share, I share my experience with this equipment while trying to be as objective as possible! Let's see what chatgpt thinks about this solution ????????: Solar water heaters have several ecological and economic advantages: 1. Renewable energy: It uses solar energy, an inexhaustible source, to heat water, thus reducing dependence on fossil fuels. 2. Reduced energy costs: Homeowners can save on their electricity or gas bill, since the sun is free and abundant. 3. Low environmental impact: Fewer greenhouse gas emissions and less pollution, thus contributing to the fight against climate change. 4. Long lifespan: Solar water heating systems are durable and require little maintenance, making them a long-term investment. 5. Subsidies and incentives: In many places, there are financial incentives in the form of tax credits or grants to encourage the installation of solar water heaters. 6. Energy Independence: Homeowners can be less vulnerable to fluctuations in fossil fuel prices by using a local, free energy source. 7. Versatile Use: Solar water heaters can be used to heat domestic water, swimming pools, or even support home heating. In short, solar water heating is a sustainable and cost-effective option for heating water, helping to protect the environment while reducing energy costs in the long run.
