Are Tankless water heaters more energy efficient compare to Tank Water heater?
There are always apprehensions when we move to newer and updated technology. And it’s no different when we tell people to upgrade to tankless water heaters.
When we suggest tankless water heaters to our friends and readers, the first question that comes up is regarding the price and savings they offer. And this prompted us to write this article where we decode the myth surrounding the energy efficiency of tankless water heaters.
The tankless water heaters are also referred to as “on-demand” water heaters for a reason. That’s because they are smart enough to heat water only when the faucet is opened. This vastly reduces the stand-by heat loss which is very high in conventional storage water heaters.
A lot of energy gets wasted in the process of heating and re-heating in a conventional tank style water heater. And this results in 30% less energy efficiency when compared to a tankless water heater. The energy efficiency of tank style water heaters reduces with time due to sediment build-up that is negligible in tankless water heaters.
Although the initial setting up cost of tankless water heaters are high you are sure to reap the benefits of their energy efficiency and durability in the long run. Speaking of energy efficiency, Bosch Greentherm C1050 with an Energy Factor of 0.95 and very high thermal efficiency is one of the most energy efficient tankless water heaters available.
So, we can conclude that Tankess Water Heaters are more energy efficient than conventional water heaters and are the go-to option when you are planning for long-term usage. Also please keep in mind that the energy efficiency of these heaters tends to slightly decrease with time due to mineral sediments in the heating chamber. So, see to that you do a regular cleaning of the heater. If you have question like how to clean a tankless water heater then must see our post on this.
