Last month we asked how much readers spent buying and installing a new water heater in their home. And you told us! We hope this information gives a basic sense of how much this new appliance costs, and how much you can expect to pay when hiring someone.

Keep in mind, this is general and prices most likely vary in cities versus more rural locations, etc…Although this gives you a rough idea, you should always seek multiple quotes for any work done in your home.

The Takeaway for Standard Water Heaters: The majority of readers went with 40 or 50 gallon heaters. On average, based on our reader reports, you can expect to spend $1017 on a 40 gallon and $1421 on a 50 gallon, with electric water heaters being a little less expensive than gas. As you can see, there are low outliers, which means that sales, deals and tax breaks can affect your bottom line significantly.

Tankless Water Heaters

A good number of you installed tankless water heaters instead of the standard variety. And here’s the break down on what you spent:
  • $1570 for a Noritz (including new gas line and installation)
  • $1800 for a Rinnai (including installation)
  • $2200 for a Rheem (including installation)
  • $2400 for a Takagi (including new gas line, electrical, exhaust and installation)
  • $2500 (including installation)
  • $2900 for a Rinnai (including installation)
  • $3000 for a Rinnai (including installation)
  • $4500 for semi-commercial Norritz (including new gas line and installation)

The Takeaway on Tankless Heaters: There was a range of prices reported, with an average of $2608 for a new tankless heater and installation. Several commenters mentioned tax credits, so if you go the tankless route, be sure to research any available incentives at both local, state and federal levels.

An Important Consideration: Information that’s not included here, for either standard or tankless heaters, is the cost of operating the system throughout the year. Tankless heaters, while more expensive at the front end, use significantly less energy, which means lower gas or electric bills each month. When you are pricing out the cost of your new unit, take the long-term costs into consideration as well.
