Tankless Water Heating Energy Efficiency

In case you didn’t know, Energy Star is part of the US Environmental Protection Agency (EPA).  Its purpose is to help businesses and consumers save money and protect the environment through what they call “superior energy efficiency.”  Energy Star is essentially the authority on all things energy related.

So, it’s no wonder Energy Star supports and promotes tankless water heaters.


Tankless Water Heaters as Energy Efficient Technology

Energy Star lets consumers know that because tankless heaters heat water on demand, they save remarkable amounts of energy compared to conventional water heaters.

We’ve all experienced firsthand the problems with standard “tanked” water heaters—they take up a lot of household space and waste energy.  The water in those tanks sits there waiting to be used and while it sits, it is continuously being heated to maintain that warm, comfy temperature.


Energy Saving Benefits of Tankless Water Heaters

It is clear that if you’re looking to save some money, while you do your part to help the environment, tankless is the way to go. On their website, the experts at Energy Star outline what they consider to be the benefits of qualified tankless, on-demand water heaters.  Here is a summary of their findings:

  • Reduce energy waste and save money: Energy Star-qualified tankless heaters save the typical family over $100 per year on utility bills.
  • Deliver continuous hot water: Conventional tanks will eventually run out of their water storage supply.  Because tankless heaters heat on demand, the water is always hot when desired.
  • Space saving design:  Tankless water heaters are fairly small and elegant in design.  They may be mounted on walls or even set up for outdoor installation.  They are far less obtrusive than their conventional counterparts.  Due to their small size, tankless water heaters allow for more flexibility in household placement.  They may be installed in more centralized locations to cut down on the time it takes for hot water to reach its destination thus conserving water and saving even more energy.
  • Provide a better investment: Well-maintained tankless water heaters can last up to 20 years—significantly longer than most standard water heaters.  Additionally, without that big, accident prone tank in your home, there is no need to fret about the possibility of significant water leakage or damage.

Proponents of tankless water heaters cannot be dissuaded.  They are believers in this advanced technology and will never go back to using standard tanks.

Supporters of tankless heaters promote the following benefits:

  • Energy efficiency
  • Longevity
  • Space savings
  • Water conservation
  • Lower monthly utility bills
  • Endless stream of continuous hot water

With all of these advantages, tankless water heaters sound pretty good, but let’s get down to the nuts and bolts here. How much do tankless water heaters cost to install? And how much do they cost to successfully operate and maintain?


Purchasing a Tankless Water Heater

The truth is that tankless water heaters are costly up-front—significantly more expensive than their standard tank counterparts.  This is because the tankless water heater installation process is rather complex.  It involves attention to: ventilation, gas supply, water quality, and electrical connections.  Stainless steel connections, serving to push the price tag even higher, are also part of the tankless installation process.


Operating and Maintaining a Tankless Water Heater

A few key factors to remember when it comes to tankless water heater operation costs are:

  • Longevity: On average, well-maintained tankless water heaters have been shown to last five to ten years longer than standard tanks. This is significant when considering money spent over time.    
  • Investment: Because tankless water heaters stand the test of time they remain a more solid home investment.  Tankless heaters tend to increase the overall value of homes at the time of resale.
  • Decreased utility bills: Tankless water heaters heat water on-demand. They do not waste energy by continuously heating a tank of water. Point-of-use tankless heaters save even more water and energy by providing immediate hot water at its designated appliance.
  • Low maintenance: Tankless heaters do not need to be professionally maintained as regularly as standard tanks. Standard tanks are always filled with water and this tends to take a toll on the system. It needs to be more closely maintained to avoid corrosion, rust, and leaks.
