Imagine getting hot water when you need it while also saving energy. Tankless hot water heaters, also known as on-demand water heaters, provide hot water only when it is needed so they don’t suffer the energy loss associated with traditional storage water heaters.
Is a tankless water heater right for your home? Here’s a look at some of the benefits.
How Tankless Heaters Work
Tankless water heaters take up much less space than storage water heaters as they heat the water directly. When you turn on the hot water, the cold water travels through a pipe and into the tankless water heater unit where it is heated by a gas burner or an electric element. This allows you a constant supply of hot water.
On average, tankless water heaters can provide 2 to 5 gallons of hot water per minute. Gas-fired tankless water heaters, according to energy.gov, can produce higher flow rates than electric models.
For those with large families who go through a lot of hot water, installing more than one tankless water heater is common. This will ensure there is always enough hot water available for showers, laundry and the dishwasher.
Tankless water heater advantages
Besides heating water on demand, there are many benefits to tankless water heaters.
While the cost of a tankless model is greater than conventional storage models, tankless water heaters use less energy and typically last longer. Many tankless models last more than 20 years, versus 10 to 15 years for storage models. On average, the typical family can save about $100 per year with a tankless model.
Tankless water heaters also take up less space than their bulky counterparts. They can be mounted on a wall in a closet or in the basement.
Also, with both gas and electric models available, that means you don’t have to re-work your home’s infrastructure and invest in pricey labor-intensive installation methods.
