Traditional tank-style water heaters take up a lot of space and many of them aren’t very efficient. They are constantly heating water which means they are always using energy. Many older tank water heaters can cost a significant amount to use, especially if you live in an average to large size home where you use a lot of hot water. Tankless water heaters require much less space for installation and most only use electricity when you turn on the hot water. These water heaters have adjustable temperatures so that you can have a safe and comfortable temperature of hot water in your home.
Some tankless water heaters are designed for use in small homes as they don’t have the ability to heat water quickly enough to work with many different water access points at one time. Others can be used in large homes and are able to keep up with your hot water demands. One of the main benefits of using a tankless water heater is that it works more efficiently and can lower the costs on your power bill.
