Tankless water heaters are becoming more and more common. What’s the difference between a standard tank water heater and a tankless? A plumber can actually show you a tankless heater, and describe the advantages of specific models, but for now, here is a basic summary.
These remarkable instruments heat water on demand. As water travels through the instrument, it is instantaneously heated. This eliminates the need for a storage container to hold pre-heated water in. Of course, a little water is stored in the heat exchanger coil. Because of its instant heating capability, the tankless water heater is also referred to as an inline, flash, instantaneous, on-demand, and instant water heater. They provide a continuous flow of hot water throughout a household. There is a water flow turbine that senses the flow of water and starts heating it up quickly. The turbine has an attachment with the control board which senses a variety of things like the temperature of the water coming in, the temperature that the user desires, and the variation between the two selections. The flow into the burner assembly is controlled when the initial electronic start-up sequence gets going. Water comes to the exact right temperature when it goes through a copper heat exchanger. When the request is gone (faucet is shut off), the tankless water heater will revert to standby mode, thus conserving energy. You could really conserve a lot of money by switching to the tankless version.
Typical tank heaters just can’t stand up to the tankless variety. Conventional water heaters are slow, inefficient, and unwieldy compared to the modern tankless water heaters. Tankless heaters were proven to save around 22% per year on a home’s energy costs according to Consumer Reports. Some manufacturers boast up to 40% savings in energy costs, and there might be models that save even more. However, three variables to consider are that tankless heaters require a larger up-front price, may have more upkeep, and the most energy-efficient versions, which are going to conserve the most money, are probably the most pricey too.
