A device with undeniable advantages
The expansion tank emerges as a pragmatic solution for households looking to reduce their water consumption. At a modest cost of €50, this equipment proves to be an effective pressure regulation system that limits water waste in water heating installations. Its role is to compensate for the variations in water volume resulting from temperature fluctuations, thus preventing significant losses.
A considerable waste avoided
The increase in pressure in a water heater can lead to impressive leaks. When an appliance reaches a high temperature, it can generate excessive pressure, causing the safety valve to open. Without an expansion tank, losses can reach 3% of the hot water tank’s volume, resulting in thousands of liters evaporated each year. Indeed, a 300-liter water heater can lose up to 3,285 liters of water per year.
An easy and accessible installation
Installing an expansion tank does not require the skills of an experienced plumber. Armed with a few simple tools, it is sufficient to attach a flexible pipe to the water inlet and set up a connection between the tank and the safety group. The tank is placed near the water heater, allowing it to effectively capture excess water. It is essential to choose its capacity based on that of the tank. The operation can be completed within a reasonable time, making this solution accessible to many.
A preservation of water resources
By adopting this device, each household actively contributes to environmental preservation. Individual actions, even modest ones, add up to create a positive impact on water resources. Households can play a significant role in the fight against waste by investing in this system, which, for a modest cost, offers substantial savings in terms of precious water.
The impact on water bills
The effectiveness of the expansion tank is not limited to reducing waste. It also helps lower household water bills. Therefore, every drop saved over the long term translates into relief for the family budget. This financial aspect, coupled with environmental benefits, makes the installation of an expansion tank not only responsible but also wise.
Frequently asked questions about the €50 expansion tank
What is an expansion tank and what does it do?
An expansion tank is a device that helps regulate pressure in a water heating system. It prevents water loss due to the opening of the safety valve by storing water that would normally be discharged.
How can an expansion tank reduce my water consumption?
By installing an expansion tank, you can avoid losing up to 3,285 liters of water per year, as it compensates for pressure fluctuations and prevents water from escaping unnecessarily.
Is it difficult to install an expansion tank?
The installation of an expansion tank is relatively simple and can be done by individuals with basic DIY skills. You just need to connect it to your water heater system.
What is the cost of an expansion tank?
The price of an expansion tank typically ranges from €30 to €50, making it an economical solution to save water on your water heater.
What size of expansion tank should I choose for my water heater?
The capacity of the expansion tank should be proportional to that of your water heater. For a 200-liter water heater, for example, a suitable expansion tank would be ideal.
Do I need to call a professional to install an expansion tank?
It is not necessarily required to call a professional. If you have some plumbing and DIY skills, you can carry out the installation yourself.
Does the expansion tank work with all water heating systems?
Yes, an expansion tank is designed to be compatible with most storage water heaters working with hot sanitary water.
What are the additional benefits of using an expansion tank?
In addition to reducing water waste, an expansion tank extends the lifespan of your water heater by protecting the safety group from wear.
Is it necessary to maintain the expansion tank?
Occasional maintenance is recommended, such as checking the pressure inside the tank and ensuring there are no leaks at the installation.
Can I combine an expansion tank with other solutions to save water?
Yes, it is possible to combine an expansion tank with other water-saving devices like thermostatic faucets or water-efficient showers to maximize savings.
