Differences Between Tankless Water Heaters And Tank Water Heaters

Differences Between Tankless Water Heaters And Tank Water Heaters


There are several differences between tankless and tank water heaters. The biggest and most obvious difference is the lack of a tank with tankless models. Another difference is the initial installation price. Tanked water heaters also lose much more energy than tankless water heaters. Tanked water heaters waste less water than tankless models. Finally, tankless water heaters have a limited hot water supply.

With tankless water heaters, the most apparent difference is the lack of a water holding tank. This is not always a good thing. It is good for the environment and can be helpful when paying the water bill. This is where the advantages stop. The tankless water heater is more costly to install in the beginning. It takes up to triple the cost of a tanked water heater to have installed.

Another difference between tanked and tankless water heaters is that tanked water heaters lose a lot of energy while waiting to be used. Tanked water heaters need to have a ready supply of hot water on demand for use. Tankless water heaters take away that need. They offer the ability to heat water for demand and not for standby purposes. This saves money in one way but wastes money in others.

Tanked water heaters end up losing less cold water than most tankless water heaters. This is because a tanked water heater has hot water ready for use and a tankless water heater does not. A tankless water heater must heat water as it is demanded meaning cold water runs down the drain until the water is hot enough to use.

A final difference is that tankless hot water heaters run out of hot water faster than a tanked water heater. A tanked water heater can hold between 20-120 gallons of hot water at a time. A tankless water heater has to heat water as it is demanded. If the demand is higher than the heating ability of the tankless water heater, then the water goes cold. Understanding the differences between the two types of water heater is important to help homeowners save money and water.
