Are Electric Tankless Water Heaters Efficient

Tankless water heaters heat water directly without the use of a storage tank.

Are electric tankless water heaters efficient.

Overall tankless water heaters are more energy efficient as indicated in the chart on the previous page. Designed for both whole house water heating and specialized applications a. Smith has the lineup of electric tankless water heaters to meet your specific needs. The normal thermal efficiency of an electric tankless water heater is 78 85.

Once you eliminate the need to heat and store water your energy efficiency is going to go up and ideally your energy costs may go down because you re using less fuel to heat your domestic water. Among electric propane and natural gas instant hot water tankless water heaters electric models tend to be the most energy efficient type. The new line of a.

Similarly electric heaters can have higher energy factor ratings than gas heaters. When a hot water tap is turned on cold water travels through a pipe into the unit. The energy efficiency of gas and propane reaches around 80 85 while the electric one reaches more than 98 which refers to the low standby loss of heat. As a result tankless water heaters deliver a constant supply of hot water.

With gas heaters you need access to natural gas or propane and you have to inspect the installation every year. In comparison gas heaters usually have between 80 and 85 percent. This is how tankless water heaters achieve their energy savings compared to tank water heaters. It takes less energy to heat water that is used rather than water that is stored because the heat in.

Either a gas burner or an electric element heats the water. Electric water heaters tend to have at least 98 thermal efficiency many are 99 percent or more. However a tankless water heater s output limits the flow rate.
