There are many tankless water heater manufacturers and models on the market. We recommend and are certified installers of Nortiz tankless water heaters. While the price of a tankless unit may not seem too expensive when just looking at the cost of the tankless unit, please be aware that they can be complex and costly to install because they often require alterations or modifications to gas lines, electrical and venting. Residential units are sized based on the number of bathrooms the tankless water heater needs to serve. As with any product, the larger the unit the more costly.

Why is it difficult to quote the cost of tankless water heaters online?

While OneStop Plumbers can easily provide a fixed price online to replace a storage water heater, because tankless water heater prices vary depending on venting requirements, gas line requirements, filters, etc., OneStop Plumbers will come to your location and provide a fixed price quote we will stand behind and honor. We do not charge to come out and provide you with a tankless water heater price quote.

Our tankless water heater quotes will always include the new tankless water heater unit with all hardware required to complete the job in accordance with the plumbing code. We will also provide itemized pricing for any desirable add-ons or options such as filters and remote controls. And because we know you don’t want that old storage unit lying around, our tankless water heater price quotes include removal and haul away of your old unit.

“Needed to replace my water heater which was about 18 yrs old making noises like a drummer in a rock n roll band.  Called a few businesses from Yelp and settled on OneStop.  They did not disappoint.  Teara was quite helpful from setting up an appointment to going over the cost in detail.  There were no surprise or additional costs added. The guys that came and did the install did a great job, friendly and informative.  Thank you OneStop!”
