The most common issue that people have with their hot water is a lack of it. You may realize that the hot water does not last long enough for everyone in your family to take a shower, or that it runs out mid-shower. These are issues that can only occur with a tank water heater. They can be solved by installing a tankless water heater.
Tank heaters heat only a limited amount of water in their tank. Larger tanks are available, but they are costly, and there is still a limit. You will run out of hot water if you use up all of the hot water in the tank before it refills and reheats.
When you turn on the faucet, tankless heaters heat up the water as it is needed. In a couple of seconds, they can heat water to a hot, relaxing temperature. They are capable of constantly supplying hot water.
