Differences Between Tankless Water Heaters And Tank Water Heaters


Naperville Water HeatersThere are many unique differences between tankless water heaters and tank water heaters. Each system offers its own advantages and disadvantages. Choosing the system that best suits your needs may be a simple matter when armed with some basic knowledge.

Most homes have a standard 40 or 50 gallon tank water heater that constantly stores hot water unit it is needed. As hot water is drawn from the tank, it fills itself back up and uses electricity or natural gas to heat the water and keep it heated. Some of the pros about the tank water heater system are that they have lower up front purchase costs, are typically easier and cheaper to install, they can use a variety of fuel methods to operate, and are cheaper to replace.

Cons of the tank water heater system are that they can run out of hot water during heavy use, hot water temperature control is not always precise, tanks are large and heavy, over time water will rust the inside of the tank and cause it to leak, and according to the Department of Energy conventional systems account for as much 14% to 25% of a home’s energy usage.

As the country continues to trend towards energy efficiency, tankless water heaters have slowly become more popular. A tankless water heater does not store any water. When water is needed, cold water travels through the tankless unit where a gas burner quickly heats it to a specific preset temperature. It will only heat water when you need it. Some of the pros about tankless water heaters are their endless hot water supply, accurate temperature control, they run only when needed offering long term energy use savings, they are small and space-saving, typically last eight years longer than conventional systems with longer warranties, and are 84% to 95% more efficient than conventional systems.

While the pros of the tankless water heater are many, they too have their share of cons. They have higher up front costs that are can be as much as three or four times a conventional system, installing is complicated and can be more expensive, the burner element that heats the water is limited to natural gas, and untreated water can lead to scaling and reduced water flow.
