Who installs tankless water heaters near me?

Plumbing companies install gas and electric tankless water heaters. Home Depot and Lowe's also offer tankless water heater installation through their network of licensed plumbers.

What is a tankless water heater?

A tankless water heater provides hot water on demand, heating water only when needed rather than continuously using fuel to heat water in a storage tank. When a hot water tap is turned on, cold water travels through the heat exchanger in the tankless unit and is warmed instantly.

  • Whole-house tankless systems deliver hot water to all the fixtures and appliances throughout the home.
  • Point-of-use tankless models are smaller units designed to provide hot water to a single fixture or appliance.

Where to install a tankless water heater?

Plumbers can install tankless water heaters on inside or outside walls, including utility rooms, attics, garages, or basements. Tankless water heaters can also be installed in place of an old tank water heater if the area provides enough combustion air. Tankless units installed outside can freeze and needs protection from the weather, direct sunlight, rain, and bugs.

How do I know if I need a new water heater?

Signs a water heater is going out:

  • Rusty, discolored, or metallic-tasting water
  • Loud clanging, knocking, gurgling, or whining noises
  • Hot water that runs out quickly
  • Low water pressure
  • Foul odor coming from hot water
  • Low or irregular water temperature, or no hot water at all
  • Leaks at the base of the tank or around the pipes at the top of the tank

Will a tankless water heater work without electricity?

A tankless water heater does not work without electricity. Natural gas and propane tankless water heaters need electricity to operate the internal PC board, ignition, and thermostat.

Gas tankless systems are:

  • More energy-efficient and saves $150 to $300 in annual operating costs
  • Warranty lasts up to 5 years longer
  • Provides a higher gallons-per-minute (GPM)
  • Most gas units are eligible for a $300 federal tax credit

Electric tankless water heaters are:

  • Cheaper to install

Ernesto was extremely helpful, and was able to get back to me within 20 minutes of submitting a request! He arrived at my house right on time, and was able to identify and fix my drainage issue right away. Being that this issue happened on a weekend, and I needed to be somewhere, I really appreciated how punctual and efficient he was. I didn't want this plumbing issue to take up too much of my day, and with Ernesto it took no more than an hour and everything was fixed. He even took the time to clean up after himself, which says a lot. Thank you so much Ernesto! I highly recommend and will be using him for all my plumbing needs.
