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.

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

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) 812-6067 now!

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.

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

Immediate response. Had new system I stalled within 48 hours of first contact. All staff members were professional, courteous and very knowledgeable. Everything was perfect. They just came out this week to make sure our ac was good to go due to winter install. No cost…

Always on time and go over and above to get the job done! Our old system died and they installed new one completely in one day. Not to mention follow up checkups to make sure that everything is running properly

An extremely professional company, from the person who sold us the unit to the gentlemen who installed the unit. They were on time and completed the work in the time they said, and cleaned up. We will use this company again. Highly recommend them.
