Tankless Water Heater Replacement Cost


How Much Do Tankless Water Heaters Cost?

Tankless water heaters are great ways to provide your home with hot water while saving space and cost on your regular utility bills. Despite their many advantages, they will occasionally break down, necessitating a repair or replacement.

Tankless water heater replacement isn't always incredibly expensive, but the cost can indeed vary a bit. Considerations such as where you live, how your home is laid out, and the type of unit needed to provide warm water for your entire home will all play into the final cost to replace a tankless water heater in your home.

How Much Will It Cost To Replace A Tankless Water Heater?

In a best-case scenario, you'll only pay $300 for a tankless water heater replacement in your home. However, should you need a higher-end unit with greater capacity, the cost to replace a tankless water heater could rise as high as $3600. The average job is $1500, so there is definitely variance in pricing.

A local plumbing specialist with experience in tankless water heater replacement will be able to provide you with a detailed and personalized estimate according to your own specific needs. 

Some variables affecting costs:

  • For electrical heating units, your home will need to be outfitted with a 220-volt electrical outlet. If you don't already have this capability in your home, it will require the involvement of a trained electrician to make the improvement. 
  • Often times, tankless gas water heaters will require gas supply line pipes that are wider than those typically found in older homes. 
  • Electrically-powered units typically cost less to install than gas units but are less frugal in their day to day operation costs.
  • Depending on where you live, certain inspections and permits may be required by local authorities before making such modifications to your home. 
  • Is there an old, broken unit in place that must first be removed, prior to installing the new unit?

A trained and certified tankless water heater replacement specialist will be able to advise you on matters concerning the tradeoffs between gas and electric models as well as what local authorities will require regarding permits and inspections. Some home improvement jobs can be tackled by the homeowner as "do it yourself" projects. Due to the variable costs and potential risk of electrocution or gas inhalation, this project would not qualify as one to try on your own.
