About Water Heater Hub
Water Heater Hub is an independent reference site for water heater decisions for water heater age, repair vs replacement, tank vs tankless costs, sizing, and maintenance. We build diagnostic tools and calculators and guides that help you diagnose water heater problems, decode serial numbers to find the age, decide repair-or-replace, and compare costs and sizes, so you can make a confident decision before you call a plumber.
How our numbers work
Every tool on this site runs on published manufacturer serial-number formats, industry-standard lifespan estimates, and market cost data collected from multiple sources. Each calculation is checked against known patterns and cross-checked with sample data before it goes live. Cost ranges are always shown with an "as of" date, because labor and unit prices vary by region and over time. We never publish a made-up statistic.
What we are not
We are not plumbers, HVAC technicians, or a water heater manufacturer. Our tools and guides are informational and aim to help you understand your situation and ask the right questions. For any repair, installation, or safety concern, consult a licensed plumber or your local building code authority before you proceed.
