Terms of Use

Last updated: November 2026

Agreement

These terms apply to your use of EcoEnergyCalc.com ("EcoEnergyCalc," "we," "our," or "us"), including its calculators, comparisons, articles and glossary. By using the site, you agree to these terms. If you don't agree, please don't use the site.

Free Use, No Account

All calculators and content are free to use and require no account. You may use the site for personal, non-commercial purposes, share links to any page, and quote short excerpts with a link back to the source page.

Please don't copy or republish substantial parts of the site, reproduce our calculators on another website, scrape the site in a way that disrupts it, or use it for any unlawful purpose.

Estimates, Not Professional Advice

Calculator results and articles are general estimates based on the inputs you enter, published data and stated assumptions, such as average energy prices, typical efficiencies and climate data. Your actual costs, savings and emissions will differ.

Nothing on this site is financial, tax, legal, engineering or safety advice. Before you buy equipment, sign a contract, claim an incentive or make changes to heating, electrical, fuel or gas systems, check with a qualified professional, your utility or the relevant government agency. Always follow the manufacturer's instructions and local codes for appliances, heaters, generators and fuel tanks.

Accuracy and Changes

We cite our sources and work to keep figures current, but energy prices, incentive programs, regulations and product specifications change often. We don't guarantee that every figure is complete, accurate or up to date. We may change, add or remove calculators and content at any time. If you find an error, please let us know; we review every report.

Advertising and Third-Party Links

The site is supported by advertising, including Google AdSense, and may contain affiliate links. Ads and links to other websites are provided for convenience. We don't control third-party sites and aren't responsible for their content, products or privacy practices. See our Advertising & Affiliate Disclosure and Privacy Policy for details.

Intellectual Property

The site's text, calculators, code, design and logo are owned by EcoEnergyCalc unless otherwise noted. Data from government and research sources remains subject to the terms of those sources. Brand and product names are the property of their owners and are used only to identify products.

No Warranty and Limitation of Liability

The site is provided "as is" and "as available," without warranties of any kind, express or implied. To the fullest extent permitted by law, EcoEnergyCalc is not liable for any loss or damage arising from your use of the site or from decisions made based on its estimates or content.

Changes to These Terms

We may update these terms from time to time. Changes take effect when posted on this page, with the date above updated.
