The Best Tankless Water Heaters in Louisville

home energy usageTankless (On-Demand) Water Heaters for Louisville Kentucky

On-Demand water heating can decrease your household’s energy usage. Tankless water heaters are a great way to meet your hot water needs on demand and conserve energy which lowers your utility bills. On average, 14% of your utility bill is a result of heating your water. Tankless water heaters, also known as demand or instantaneous water heaters, provide you hot water only when you need it, unlike tank water heaters that continuously run to keep the tank full of hot water. So, since you are only heating the water that you use when you use it, you can lower the energy consumption and save money.

Benefits of tankless (demand or instantaneous) water heaters.

  • Tankless water heaters operate on demand to heat water only when you need it. This may reduce your annual energy costs by as much as 35%.
  • A tankless water heater is up to 40% more energy efficient than a natural gas tank water heater and up to 55% more efficient than an electric tank water heater.
  • Tankless water heaters reliably provide hot water whenever you need it and at a preset temperature. If the unit is sized properly, you will not run out of hot water even when you’re the fourth person to take a shower in the morning.
  • Professionally maintained tankless water heaters have a longer life expectancy than tank water heaters. They will operate as long as 20 years as compared to an average of 10 years for a tank water heater.
  • A tankless water heater is compact in size which takes less space; therefore, you have more options on where it can be installed in your home.
  • Tankless water heaters can be safer since they only operate when hot water is needed unlike tank water heaters that are constantly heating and reheating water. Many tankless water heaters have several features to further increase their safety. For instance, some models include monitoring systems that provide information about water pressure and flow; and, if a system fails, it would automatically turn off the heater.

It is very important to rely on a licensed plumber to install your tankless water heater.

Key Things to Consider When Choosing the Right Tankless Water Heater for Your Home

Heating your water is the 3rd largest energy user in your home, accounting for about 14% of your utility bill. That adds up to a lot of money, so here are some things to consider when selecting a tankless water heater.

Flow Rate
Determine the peak water usage to meet your family’s hot water needs. How much hot water will you need if you often have two showers running while the dishwasher and washing machine are also running? What is the resulting required flow rate? Not sure? Use this information as a guide… smaller numbers for newer equipment and larger number for older equipment. 

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

You may lean toward saving money with a less expensive tank water heater, but don’t forget about the energy savings. You may save money on the equipment but not get as much savings on your utility bills. It’s a matter of instant savings verses larger long-term savings.

Power Source
Electric tankless water heaters may place a higher load on your home’s electrical system which can require costly electrical upgrades. Things like not having the correct wire size can be unsafe. Gas and liquid propane tankless water heaters are most commonly used since they are more powerful than electric tankless water heaters. Of course, your home must have access to natural gas. 

Installation and Maintenance
Proper installation is required for your unit to operate at optimal energy efficiency which translates to energy savings. Proper installation takes into account fuel type, climate, local building code requirements, and safety issues. So, it’s in your best interest to have a Jarboe’s Plumbing, Heating & Cooling plumber install your tankless water heater.

Tankless Water Heater Repair

Many people choose tankless water heaters because they are low maintenance and very efficient, but they can still have problems such as:

  • Mineral Buildup
  • System Overload
  • Cold Water Sandwich
  • Air Supply or Exhaust Blockage
  • Ignition Failure
  • Flame Failure

If your tankless water heater is acting up, schedule a time for one of our experts to come out to repair your tankless water heater. If it’s an emergency, please call us right away.

Tankless Water Heater Maintenance

Tankless water heaters can last 20+ years if they’re properly maintained. They are marketed as “low-maintenance” units as compared to regular tank water heaters. While that is true, a tankless water heater is not a “no-maintenance” appliance. It does require preventative maintenance to lessen the chance of future problems. 

Water hardness is something that can lead to the need for a repair. The tap water that runs through your tankless water heater always has trace elements of minerals that can build up over time within the heat exchanger, plugging up the passages so that water can no longer flow. This causes your water heater to work overtime to heat your water. Eventually this will shorten your tankless water heater’s lifespan and raise your energy bills. Plus, this mineral buildup on the heat exchanger can cause irreparable damage, requiring the replacement of the heat exchanger or the entire unit.

The harder your water, the more minerals it contains and the more scaling that occurs. Descaling is a process that removes the crud in the unit by running a significant amount of vinegar water through the system, followed by flushing the system for about 45 minutes. Flushing the system removes the vinegar and any other debris from the unit.

During a regular maintenance visit, Jarboe’s Plumbing, Heating & Cooling will descale your tankless water heater to make sure there’s no buildup around the heating elements. Regular maintenance will keep your tankless water heater running efficiently and effectively over the course of its lifetime.

Tankless Water Heater Replacement / Installation

Your tankless water heater should last for around 20 years, which is double the lifespan of a traditional water heater. If your tankless water heater exceeds that age, you should consider replacing it with a newer, more energy efficient model.
