Tankless water heaters are a relatively new in Huntsville, having been very popular in Japan and Europe for years due to the limited space in homes. They are much smaller than standard water heaters, averaging about the size of a small suitcase. Due to their smaller dimensions, installation options are much more varied, as the units can be installed nearly anywhere. And if there is no convenient location in your home for a tankless water heater, it can be mounted on an exterior wall, but preferably installed inside the home to prevent winter weather from impacting its performance.
Tankless water heaters differ from conventional units in several ways, most notably the absence of a storage tank, hence the name. Tankless heaters use a combination of gas and electricity to ignite a small burner within the unit and heat the water as it is passed through the maze of piping inside the casing. Because there is no supply of previously heated (a full tank) water ready to feed your home, the time to get hot water to a faucet is slightly longer with a tankless water heater setup. However, once the water reaches the fixture, it is endless, which is the major benefit of tankless systems.
