Estimates, not guarantees
Results are provided for general information and planning purposes only. Actual consumption, savings, cost, performance, and payback may differ because of utility rates, weather, installation, equipment condition, product differences, occupancy, and behavior.
Your responsibility
Review every input and assumption. Confirm product specifications with the manufacturer, verify utility rates with your provider, and obtain professional advice before purchasing equipment, modifying a building, or performing electrical, mechanical, or plumbing work.
No professional advice
The site does not provide engineering, electrical, financial, legal, or energy-audit services. Results should not be used to determine code compliance, equipment safety, wiring capacity, or structural suitability.
No warranties
The site and calculations are provided on an “as is” and “as available” basis without warranties of accuracy, completeness, fitness for a particular purpose, or uninterrupted availability, to the extent permitted by applicable law.
Limitation
To the extent permitted by applicable law, the site owner is not responsible for losses arising from reliance on calculator results. Some jurisdictions do not allow certain limitations, so those limitations may not apply to you.
