When it comes to choosing a water heater, a tankless system is often the preferred option due to its energy efficiency and space-saving benefits. However, it???s important to remember that even a tankless water heater requires an expansion tank to ensure proper function and safety.
What is an Expansion Tank?
An expansion tank is a small device that is installed onto the piping system of a water heater. Its purpose is to help regulate the pressure within the water heater and prevent damage to the system.
Without an expansion tank, the pressure within the water heater can become too high, causing damage to the system over time. This can result in leaks, burst pipes, and even an explosion in extreme cases.
How Does an Expansion Tank Work?
An expansion tank works by absorbing excess water pressure that is created when the water in the heater heats up and expands. The tank acts as a buffer, allowing the water to expand without causing damage to the system.
When the water in the system cools down and contracts, the expansion tank releases the excess pressure back into the system, maintaining a stable pressure level.
Why is an Expansion Tank Necessary for Tankless Water Heaters?
While tankless water heaters don???t have a storage tank, they still require an expansion tank. This is because the water in the system still expands and contracts as it heats up and cools down.
Without an expansion tank, the pressure within the tankless water heater can become too high, causing damage to the system over time. This can result in leaks, burst pipes, and even an explosion in extreme cases.
How to Install an Expansion Tank for a Tankless Water Heater
Installing an expansion tank for a tankless water heater is a relatively simple process that can be done by a professional plumber or a knowledgeable homeowner.
The tank is typically installed on the cold water line before it enters the water heater. It???s important to ensure that the tank is properly sized for the system and that it is installed according to the manufacturer???s instructions.
Benefits of Installing an Expansion Tank for Your Tankless Water Heater
Installing an expansion tank for your tankless water heater can provide a number of benefits, including:
- Preventing damage to the system
- Reducing the risk of leaks and burst pipes
- Extending the lifespan of your water heater
- Maintaining a stable water pressure level
- Ensuring the safety of your home and family
Conclusion
If you???re considering a tankless water heater for your home, it???s important to remember that an expansion tank is a necessary component for proper function and safety. By installing an expansion tank, you can help prevent damage to your system and ensure the safety of your home and family.
