Tankless Hot Water Heaters FAQs

You can always contact our team with questions about water heaters, or repairs. Here are some questions our customers often ask!

A tankless hot water heater is a type of hot water heater that heats water on demand rather than storing it in a tank. These systems are designed to be installed directly on your home’s water supply lines, which allows them to take up less space than traditional hot water tanks.

A tankless hot water heater works by heating water as it flows directly through the unit, using a gas burner or electric element. It heats water only when it is needed, rather than continuously heating and storing it in a tank.

A tankless hot water heater is more energy efficient than a traditional storage tank hot water heater, as it only heats water when it is needed, reducing standby heat loss. They also take up less space, and provide hot water on demand.

When you buy your tankless hot water heater from Action Furnace, we go through a detailed installation process to make sure your new unit is set up correctly. This process may include:

  • Running new gas or water line
  • Connecting the unit to your home’s water supply lines
  • Testing the system to make sure it’s functioning properly

We can usually install tankless water heaters in less than a day (and often in just a few hours). If there are any factors that could cause your installation to take longer, we’ll be sure to let you know ahead of time so you can prepare.

The cost of installing a tankless hot water heater will vary depending on the type of system, the size of your home or building, and the condition of your existing plumbing. On average, it can cost between $1,500 and $3,500 to install a tankless hot water heater—but contact Action Furnace and we’ll provide an up-front quote you can trust, thanks to our No Surprise Guarantee on pricing.

Do not attempt to install a tankless water heater by yourself, as this can cause damage to your new heater or plumbing, and may also affect your heater’s warranty. Instead, contact Action Furnace and let us make sure your system is installed properly.

Tankless hot water heaters require regular maintenance to keep them at peak performance levels throughout their lifetime. These include:

  • Cleaning the burners or heating elements to ensure proper operation and efficiency.
  • Flushing the unit to remove any mineral buildup, which can reduce efficiency and damage the unit.
  • Inspecting filters to ensure they do not need to be cleaned or replaced.
    Monitoring water pressure and temperature to identify issues such as mineral buildup, leaks and faulty parts.
  • Keeping the area around the unit clean and free of debris to ensure proper operation and prolong the life of the unit.
  • Checking for leaks and having them repaired immediately to prevent damage to the unit and surrounding areas.

It’s also a good idea to have your tankless water heater serviced annually by our professionals. Contact Action Furnace to arrange for maintenance or repairs on your tankless water heater so you can keep getting hot water when you need it.
