What’s the best way to ensure the convenience and reliability of hot water in your home? Most homes rely on a conventional water heater that stores water in a tank and heats it continuously. If you are in the market for a new water heater, it may be time to consider a tankless water heater. A tankless water heater does not store hot water, but rather heats the water on demand. Although the upfront cost can be much more than for a regular water heater, when sized and installed properly, a tankless water heater can be an economical solution for providing hot water to your home.
Here’s why a tankless water heater may be right for you.
1. Save energy and money
Keeping water hot all the time takes a lot of energy. A conventional system heats and reheats 50 or more gallons of water to ensure that hot water is always available. In contrast, by only heating the water when it is needed, tankless water heaters can lower a home’s energy cost by 30 to 50%. A tankless system is also more energy efficient. As much as 97% of the fuel consumed goes directly to heating the water.
2. Provide a continuous hot water supply
Despite continuously heating water, depending on the size of the water tank and how much hot water your family uses, a traditional water heater can run out of hot water. Because a tankless system works on demand, it provides an endless supply of hot water. No more cold showers or long waits for the tank to recover.
3. Require less space
Tankless water heaters are compact — about the size of a small suitcase, and are mounted on the wall, saving floor space.
4. Work with different types of fuel
Tankless water heaters can operate on natural gas or propane, or electricity. Electric systems are the most efficient, although a gas system may be cheaper to operate and will typically last longer.
5. Reduce the likelihood of leaks or flooding
Because the water isn’t being stored, there is far less chance of developing leaks. Tankless water heaters also eliminate other problems associated with water tanks, such as sediment buildup, tank noises and recovery time.
6. Last longer
While tankless water heaters cost more to purchase and install, they last up to twice as long – as long as 20 years, compared to 8 to 10 years for a conventional system.
7. Provide cleaner, fresher water
Because the water is not sitting in the tank for long stretches of time, but rather comes directly to your faucet, it is as clean and fresh as your water supply.
