Terms of Use

Last updated 2026-06-17. Using this site means you accept the terms on this page. If you do not agree with them, please do not use the calculator or read past this line.

What the calculator is for

The tool on this site turns a handful of inputs, fuel type, coverage, install complexity, and ZIP, into a cost range for planning purposes. It is a research aid for comparing a plumber's bid against a broader market number, not a quote, bid, or appraisal. No installer is bound by anything this site displays.

No professional relationship

Nothing on this site creates a contractor, plumbing, engineering, or financial-advisory relationship between you and Tankless Water Heater Cost or its owner. We do not inspect homes, size equipment, or pull permits. For any of that, talk to a licensed plumber in your area.

Accuracy of published figures

Cost ranges and reference tables are checked against the sources described on the editorial standards page at the time they are published or updated, but pricing shifts with materials, labor markets, and local permit fees. We do our best to keep numbers current and correct errors readers flag through the contact page, but we do not guarantee that any figure on the site matches what you will be quoted.

Referral links and advertising

This site carries Google-served display ads and a limited number of links to contractor-matching services. If you click through one of those links and it leads to a job, the operator of that service may pay us a referral fee. That arrangement does not change which numbers we publish.

Limitation of liability

The site and its content are provided as is, without warranty of any kind. To the extent allowed by law, Tankless Water Heater Cost and its owner are not liable for decisions made, or contracts signed, based on information found here.

Changes to these terms

We may revise this page as the site or its offerings change. Continued use after an update means you accept the revised terms. Questions go through the contact page.
