Tankless Water Heaters

Tankless On-Demand Water Heaters for Residents Living in or Near Indianapolis

On-demand hot water 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.

Water heating is the 3rd largest energy user in the home which means that choosing an efficient water heater is very important to your budget. If you’re looking for a new water heater, it’s a great time to consider a tankless water heater.

What is a Tankless Water Heater?

Let’s start by understanding what a traditional water heater is. Most people have a water heater that has a storage tank filled with water. That water is continually heated to the temperature that you have selected so that it is available whenever you need it. The problem is that it is being heated 24/7, and you are probably only using water a small fraction of that time. So you’re paying to keep water heated when you don’t need it which means you are using more energy and paying more in utility bills.

A tankless system doesn’t have a storage tank. It is able to heat water quickly and deliver it to you when you need it… on demand. You will save on your energy bills with this more efficient way of heating your water.

There are some definite advantages to tankless water heaters…

  • Up to 40% more energy efficient than a traditional natural gas water heater
  • Up to 55% more efficient than an electric water heater
  • Shuts-off automatically when hot water is not needed… saving energy and saving money!
  • Compact wall-mounted unit with a life expectancy of 20 years, whereas hot water tanks usually last around 10 years.
  • Water hasn’t been sitting in a storage tank that likely contains sediment.

Tankless water heaters are a larger upfront investment than traditional water heaters. However, when making your decision, you should consider more than the initial price tag. With the energy savings and the longer lifespan of a tankless system, you’ll probably come out ahead over time when you invest in it over a tanked water heater. Tankless water heaters should be installed by a licensed plumber. If you are replacing a traditional water heater, you will need an experienced plumber to safely remove your current water heater and connect you tankless unit. This isn’t a do-it-yourself project.

Benefits of tankless (on-demand or instantaneous) water heaters. 

Tankless water heaters have a longer life. A tankless water heater system will provide hot water for about 20 years. That’s about twice as long as a traditional water heater which typically operates for about 10 years. So, you won’t need to re-invest in a new water heater as soon with a tankless system.

Tankless water heaters are compact and mounted on the wall which means they don’t require as much space as a traditional water heater. A tankless system is a great option when the physical size of a new water heater won’t fit in the available area. Plus, by eliminating the traditional water heater, you’ll free up a lot of space for other uses.

They provide endless hot water on-demand. Since a tankless system heats water as you need it, you don’t have to worry about running out of hot water when you’re the last in the family to get a shower. You’ll still have as much hot water as you want.

Tankless water heaters save you money. A traditional water heater is always using energy to heat and reheat your water. Why pay to heat water when you don’t need it yet? And why pay to keep it hot when you didn’t need it in the first place?

Tankless water heaters require less maintenance. Sediment build-up and corrosion are not big problems for tankless water heaters like they are for tanked water heaters. Plus, maintenance doesn’t include draining and refilling a 40 – 50 gallon tank.

  • Tankless water heaters are a reliable source of 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.
  • 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.
  • 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.
  • 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.
  • 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.

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

Important Factors to Consider When Choosing a Tankless Water Heater for Your Home

Heating your water is the third largest energy user in your home, accounting for about 14% of your utility bill. You can reduce that amount by choosing an energy efficient tankless water heater. Here are some things to consider when selecting a tankless water heater.

Cost. 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. 

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. 

  • 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

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 Mr. Plumber expert install your tankless water heater.

Maintenance for Tankless Water Heater 

Tankless water 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.  Tankless water heaters can last up to 20 years with proper preventative maintenance.

Hard water 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 more minerals there are in your water, the more scaling that occurs. Descaling is a process that removes the buildup 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, Mr. Plumber 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.

Replacement / Installation for Tankless Water Heater 

Your tankless water heater should last twice as long as a traditional water heater, or around 20 years.  If your tankless water heater lasts much longer than that, you should consider replacing it with a newer, more energy efficient model.
