Tankless Water Heater Installation & Replacement

Whether you are installing a new tankless water heater, are upgrading from a conventional system, or are replacing an existing tankless model, you can count on Classic Aire Care for a fast, professional installation. Our plumbing experts have extensive experience with tankless water heater systems, and they know how to design the system properly to ensure it meets your hot water demand effectively. Our installation process includes:

  • Removing the existing water heater, if necessary
  • Calculating hot water demand
  • Choosing an appropriate water heater, or heaters, to meet your needs
  • Upgrading gas or electric service, if required
  • Installing the water heater and testing its performance

Some homes are best served with a single, centrally located water heater, while others may benefit from two or more tankless water heaters located closer to the point of use. Our plumbing experts will discuss your options and design the best system to meet your needs.

Rebates for Tankless Water Heater Installation in St. Louis

While a new tankless water heater can provide a nearly endless supply of hot water on demand while saving you in energy bills, it may even come with hundreds of dollars back in your pocket! That’s because many St. Louis-area utility companies offer rebates for the installation of energy-efficient tankless water heaters. 

Here are just some of the available rebates:

  • $300 for a gas tankless water heater installation from Spire
  • $200 for a natural gas tankless water heater installation from Liberty Utilities
  • $100 for a qualifying electric water heater installation from Boone Electric Cooperative

Here’s where you can find more information about local rebates you may qualify for by installing new energy-efficient water heaters.

Tankless Water Heater FAQs

Check out these FAQs for some helpful information about tankless water heaters. Whenever you’re ready for answers specific to your needs and situation, simply contact Classic Aire Care.

What is the advantage of having a tankless water heater?

Tankless water heaters are an energy-efficient upgrade for many homes in the St. Louis area. Because they lack a storage tank, there’s no need for continuous reheating of the water in the tank. Instead, these water heaters heat water on demand, which can:

  • Save energy
  • Reduce your utility costs
  • Provide a nearly unlimited supply of hot water when installed correctly

How much does it cost to have a tankless water heater installed?

The exact cost will vary depending on the brand, model, and size, but tankless water heaters do cost more than conventional storage (tank) water heaters. If you’d like a free estimate, call 314-352-1111 now!

What size tankless water heater do I need for a family of 5?

The calculation for determining the size of the right tankless water heater to meet your needs isn’t really dependent on the number of people in your home. Instead, plumbers will take into account factors like:

  • The number of devices or fixtures in your home that you want to run
  • Device flow rates
  • The required temperature rise
  • The type of system you plan on installing (gas vs. electric)

Give us a call today to set up a consultation with our team.

How many years does a tankless water heater last? 

Tankless water heaters have a longer service life than traditional water heaters, generally lasting up to 20 years.
