Tankless water heaters are on-demand devices. For large families or families who demand a lot of hot water, this could be the most important reason to buy a tankless water heater. Hot water can still be produced instead of having to wait for an entire water tank to warm up after a series of showers have depleted the supply.
Because there is no tank of standing water that requires its temperature to be maintained, tankless water heaters can reduce their overall demand for energy resources. Electric tankless water heaters do not have a standing pilot or intermittent heating required to maintain hot water availability. They are particularly environmentally friendly if the electricity used to power them is obtained from renewable sources.
Long life expectancy
Tank water heaters have a lifespan of approximately 15 years. With proper maintenance, a tankless water heater can be used for up to 20. While there are more parts that can fail, most parts are replaceable or serviceable unlike a tank style water heater. .
More maintenance is required for tankless water heaters than for water heaters. At a minimum, complete maintenance of the unit should be performed annually. Compared to a tank heater that only needs to be flushed out once a year and has the anode rod replaced every three years, this looks like a minus. The glaring difference is that maintenance of the tankless water heater can easily be performed by homeowners. Replacing an anode rod is usually the job of a hired plumber.
Living space and storage space are often the main concerns of homeowners. It’s no mystery that replacing a 40 gallon water tank with a 20 x 15 inch unit will save a generous amount of valuable space.
