Advantages of Tankless Water Heaters

When selecting a new water-heating system for your home, it can be difficult to choose between a tankless unit and a traditional water heater. There are many advantages to installing a tankless water heater, including:

  • Save space: Tankless water heaters take up less space than traditional water heaters because they do not have a storage tank.
  • Don’t wait for hot water: Because tankless water heaters heat water on demand, there is no risk of running out of hot water.
  • More energy-efficient: Tankless water heaters use less energy than traditional water heaters because they only heat water on demand and don’t heat — and reheat — a full tank of water.
  • Increased safety: Tankless water units can be safer than traditional units because they only operate when needed and don’t run continuously, like traditional units. This can diminish the strength of the core elements of the unit and the storage tank. Most tankless water heaters also utilize a number of safety features that will turn the unit off if a pressure or flow problem occurs.
  • Longer life expectancy: Tankless water heaters can last as long as 20 years or more, which can almost double the life expectancy of a traditional unit.

Nice Heating & Air is proud to service and install all Navien tankless water heaters.

Common Concerns With Tankless Water Heaters

There are large differences between tankless water heaters and traditional units. When deciding to install a tankless water heater, there can be common concerns. Some of these can include:

  • Higher upfront costs: The initial cost of the system can be more expensive, but the energy savings you receive can help outweigh the price of your system.
  • More installation needs: When installing the system, extensive piping, proper venting, and electrical expertise are necessary for proper installation.
  • Needs regular maintenance: Corrosion and mineral buildup may occur if the unit is not flushed every six months.
  • Product overload: A problem called product overload can occur if the heater was improperly sized or is subjected to heavy use.

Tankless Water Heater FAQs

What is the life expectancy of a tankless water heater?

Most tankless water heaters will last 20 to 25 years, or about twice the service life of a storage tank model.

Do tankless water heaters provide instant hot water?

Tankless water heaters heat water on demand, but it will take a few seconds to reach the tap after the hot water is turned on. For faster hot water, consider adding a recirculation system, which ensures hot water is always available right away at your faucets.

Can I directly replace a storage tank model with a tankless water heater?

Though tankless water heaters are more efficient, some homes may require upgrades to the gas valve or electrical service to provide the higher instantaneous energy necessary for a tankless water heater to heat water quickly.

Do I need a water softener for my tankless water heater?

If you have hard water, a water softener may reduce your maintenance requirements, as tankless water heaters are vulnerable to limescale and mineral accumulations that could clog the heat exchanger.

Does a tankless water heater really provide unlimited hot water?

If it is sized correctly for your home and installed properly, a tankless water heater can provide a virtually endless supply of hot water. Our experts at Nice Heating & Air can make sure your home has all the hot water it needs with our professional tankless water heater installations.

John G.

“Five stars--could not be happier!  Josh and Kyle were very professional, provided several options to improve performance of HVAC, no pressure or time constraints, worked efficiently, were able to explain in clear terms what they found, including when items were performing in fine fashion and nothing needed to be done.  Thanks for a happy camper”


“Service was outstanding from the time of arrival which you could track arrival time live on a website link they send you so you know when they will arrive. Technical knowledge was very high, quick and efficient Kyle and his partner both handled the install of a Sensi Predict as if it was a walk in the park. I highly recommend Kyle from Nice Heating & Air for all HVAC issues and for new installs, him and his team are an amazing company and will think of them first if any issues arise in the future for sure....”

Andrew Baker.

“Professional and polite. Excellent communication throughout the maintenance visit. Definitely recommend.”


“Rolando Medrano was very professional and followed the CDC protocol of 6 feet social distance and had a mask and put disposable shoe covers before entering the house. He made sure to address all of our issues and provided answers for all our questions. He came on time and called before he came to update on timing and his status! He was a great help!”

Mike Richardson.

“Highly recommend Nice Home Services for your HVAC needs. Have been member of their annual maintenance plan for three years now and been extremely pleased with their approach to business. They are professional, knowledgeable, and relatable. The service specialists take their time to fully diagnose the issue and explain the situation in a way that is easy to understand. Never had an instance where they try to push product and instead look for ways to recommend how to save you money. Need anything done on your home's HVAC, call the folks at Nice Home Services and know you're making the right choice.”

Zora G.

“Love , Love the NICE Heating & Air company for their kind & trustworthy technicians, their unbeatable price & overall knowledge they’ve amazed me every time with their fabulous job on my house, I’ll recommend them without hesitations, try this company you won’t regret for sure.”

Richard Nowinski.

“Dionte and his helper (Josh) did a superb job with the installation. The result is both functional and as cosmetically pleasing as the ideal water heater installation can be. They were VERY careful moving the old one out and the new one in so as to assure no damage was initiated neither to the heater nor to our dwelling. He explained his intended design prior to execution and executed it flawlessly. This was followed by a comprehensive explanation of the functional options available through the control panel and Ipad app. Cleanup at conclusion of the install was appropriate and comprehensive. This team represented both Nice Heating and Rheem VERY positively!”

Kimberly Mason.

“I had the pleasure of meeting another NICE Heating and Air Service Technician today, Mr. Jeremy Castellon.

Jeremy was very professional and competent.”

Terence Lartey.

“I purchased my HVAC unit a year ago along with a Cozy Club maintenance plan. It's been running great and the customer service team is always quick to respond to questions. Today Rolando M. came by for the maintenance check and, as usual, he was neat, professional and maintained the COVID rules. He was also very nice, living up to the company name. I'm very happy with my experience with Nice.”

N. England.

“I can't speak highly enough of this company. I requested an appointment, and it was scheduled for the next day. The technician was polite, honest, and a pure delight to work with. He didn't try to overcharge or tell me to replace something I didn't need to. He made service recommendations that were in line with industry standard prices so I could make an informed decision as he went about his service visit. Would recommend and will be using them again in the future. ”

Lucas W.
