Benefits Of A Tankless Water Heater
Did you know that your water heater runs most of the day, even if you are not using the water in your house?
Water cools and is re-heated in a standard heater tank several times each day while no one is home. This is just wasting energy and running up your utility bills. Tankless or on-demand water heaters heat water only when it’s needed, eliminating the need for a storage tank and the standby losses associated with constantly maintaining a tank full of hot water. Most tankless water heaters have a life expectancy of about 20 years, much longer than any conventional tank-type water heater. They also eliminate the risk of tank leaks and water damage.
A smaller footprint that packs a punch!
If you grew up in a home with lots of people taking showers and running appliances, you’ve probably experienced what it feels like when that big tank runs out of water. Not too fun, is it? So how can this box, about the size of a suitcase, mounted to your wall keep your showers hot and your tubs full?
- Cold water enters the inlet only when hot water is required
- A flame ignites and heats two heat exchangers, which heat the water
- Heated water exits the outlet pipe to travel through pipes to where it is needed
- The heater will adjust the flame and water flow output as needed to ensure a temperature set point is maintained
- When no more hot water is required, the system shuts off until hot water is needed again
Seriously. When you consider the space savings, eco-efficiency and an endless supply of hot water that come with tankless technology, there is no comparison. But when you look at the cost savings over the long run, well, it just keeps getting better. More comfort for less money? Talk about a no-brainer.
That may sound all fine and dandy, but how much money will a tankless water heater actually save you?
Well, for homes that use 41 gallons or less of hot water daily, tankless water heaters can be 24%–34% more energy efficient than conventional storage tank water heaters. They can be 8%–14% more energy efficient for homes that use a lot of hot water — around 86 gallons per day. You can achieve even greater energy savings of 27%–50% if you install a Tankless water heater at each hot water outlet. Estimates show that a typical family can save $100 or more per year with a qualified tankless water heater.
The initial cost of a tankless water heater is greater than that of a conventional storage water heater, but tankless water heaters will typically last longer and have lower operating and energy costs, which could offset its higher purchase price. Most tankless water heaters have a life expectancy of more than 20 years! They also have easily replaceable parts that extend their life by many more years. In contrast, storage water heaters only last 10–15 years!
