Estimates, not advice

The comparisons are estimates built from public data and assumptions about the future. They aren’t financial, tax, legal, insurance, or engineering advice.

Check before you commit

Get real quotes, check your state’s rules and incentives, and ask a licensed professional before you buy or install anything.

Data can lag

Sources update on their own schedules, and each number shows its date. If a source stops answering, we show the last values we had, with their date.

No endorsements

Naming a make, model, or type of heater isn’t an endorsement. No maker, dealer, utility, or installer pays for how anything appears here.
