Energy Savings From Tankless Water Heaters

Tankless water heaters are increasingly increasing in demand over the past five years. More and more homes are using this type of water heating systems because of their different advantage to the homes with tankless water heaters installed.  

Tankless Water Heater 101

On-demand water heaters, as tankless water heaters are also called, work by providing hot water when it is needed. These heating systems would have sensors on board to monitor and control demand and flow of water and the rate of flow to supply just the right amount of hot water needed for the current demand.

There are three major types of tankless water heater systems: electric, natural gas, and propane-fired models. There are a lot of advantages to these type of water heating systems. One advantage seen in using these systems are the energy savings gained from using tankless water heaters.

Fuel Savings from Tankless Water Heaters

Energy savings from tankless water heaters come from the fuel saved by using these systems. There is no need to maintain a supply of hot water, and there is no need for containers or tanks to keep the hot water supply. Because there is no need to keep the system turned on to maintain the hot temperature, there is no need to needlessly consume fuel. Tankless water heaters turn on and off in the time needed to maintain the temperature of water for use. Fuel use is also limited to the amount of hot water being demanded. It would require fuel to heat water needed for a single sink than it would to provide water for multiple water fixture all at once. These heating systems work by heating water to a specific point when it is demanded, and it would simply shut off when water has reached that specific temperature, and when there is no longer a demand for that waster.

Fuel-Efficiencies of Tankless Water Heaters

Energy saving from tankless water heaters can also come from the fuel efficiencies of the heating system. Water heaters without tanks need only heat the needed water to a certain point or temperature at a specific rate. There is no need to keep heating when the valve has been shut off. Tankless units have a modulating "always off" capability. This capability can provide reduction of fuel use up to 50% as fuel use is limited to only there is a need for hot water and for the amount of hot water needed.  This control feature also adds to the fuel efficiencies in operating a tankless water system. You would only use the exact quantity of fuel needed to heat the needed water. Energy saving due to efficiencies can even go beyond 50% depending on the size of the water tank the tankless water heater would be replacing. Comparing the energy consumption, which can be found in the yellow "Energy Guide"sticker, of your existing heater and the tankless water system heater you are considering will give you an even better idea of what to expect regarding fuel efficiencies and fuel savings.

With the demand for tankless water heaters, and the need for energy savings for the household, it is a good idea to look into the possible advantages of changing your current water heating system to a tankless water heater system. It just might save you, fuel and energy and in the long run, money.
