If you upgrade to a tankless water heater, you could make a valuable dent in your energy bills.

The tankless water heating unit works differently than conventional gas water heaters and their electric counterparts. This water heater works on-demand producing only the needed amount of hot water.

What’s So Great About Tankless Hot Water?

Tankless water heaters have become quite popular throughout the Louisville area over the last many years, largely in part due to the energy savings they tout. But that’s not the only good thing you get when you upgrade! Take a look at the lesser known benefits before you make a purchase decision.

  • With tankless gas water heaters or electric ones, the system’s heat exchanger only warms what whenever a tap in the home turns on the hot water. This way, there’s no wasted energy on storage and that alone can generate as much as 35 percent in energy savings during a year.
  • Compared to tank gas water heaters, a tankless gas water heater is as much as 40 percent more efficient. The tankless gas model is as much as 55 percent more efficient than tank water heaters that run off electricity.
  • With a properly sized tankless unit, you’ll always have enough hot water, whenever you need it! Sizing is determined using the unit’s flow rates to ensure a good fit. With the right model, there will be ample hot water even after five showers in a row!
  • With professional maintenance, tankless water heaters overshadow tank models in terms of expected service life two-fold. These water heaters can last 20 years or more, while tank water heaters typically last 10. You won’t need to deal with system replacement nearly as much.
  • Small in size, tankless water heaters can squeeze into areas that tank models cannot. They may be installed up on a wall or on the floor, in a space offering very little clearance.
  • Since your water heater won’t be running all the time, your home becomes safer! What’s more is that many tankless systems have integrated safety features to help protect your family. On-board monitoring continually gauges water pressure and water flow, then shuts down the system if a failure is detected.

Criteria to Consider when Purchasing a Tankless Water Heater

As your home’s third largest consumer of energy, the water heater you select to replace your existing model, whether it be tank or tankless, will have a direct impact on your future utility expenses. Make a move toward greater savings and energy conservation when you select a new tank water heater that meets the following guidelines:


Flow Rates

Flow rates are how you’re going to figure out what size tankless water heater you need. First, you have to figure out how much hot water is consumed by your household at the peak point of usage. How many hot water applications run at the same time and what are they? Add up the amount of gallons of water they require in a minute and you’ll find the flow rate you need in order for the tankless model to satisfy the needs of your home. You may use the following averages to estimate if you don’t have specific numbers for your appliances and plumbing fixtures:

  • Faucets: 0.75 gallons to 2.5 gallons per minute
  • Low-flow shower heads: 1.2 gallons to 2 gallons per minute
  • Older standard shower heads: 2.5 gallons to 3.5 gallons per minute
  • Clothes washers and dishwashers: 1 gallon to 2 gallons per minute


It’s tempting to save money and select a lower priced unit, but you’re probably spending more if you’re missing out on the big picture: operating costs. Purchase price tells you how much you’ll pay now for the thing, while operating costs tell you how much youll pay as you use the system for years and years. Cheaping out initially could cost you big time, so make sure you see how all options stack up operations wise.

Fuel Source

Is your home equipped with both natural gas and electric service? If so, you may have more choice in your water heater selection. If your home is ready to accommodate a new hot water heater, you can have your pick of tankless gas water heaters or electric water heaters. Explore utility rates to determine the most affordable option for your family.

Keep in mind that replacing water heaters with those of the same fuel source still might require some work to be done. For example, electrical service may need expanded in your home for new outdoor lighting. Misplaced wires also create issues.

Installation and Maintenance

Choose a highly skilled plumber to install your new tankless unit – you want the very best on the job to protect the integrity of that expensive new equipment. Always schedule maintenance and remember to get it done – call anytime!

Maintenance for Tankless Water Heaters
