Generic cost pages skip the things that actually decide your price and your unit’s lifespan here — local code, water, and the money you can claim back.
Recommended unit for Philadelphia
Given Pennsylvania’s humid continental (cold northern winters) climate and gas water heating, high-efficiency gas is the sensible default for most Philadelphia homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.

What Philadelphia code requires

- Good to know—
Water heater work is governed by the statewide Uniform Construction Code (UCC), but permitting and inspections are administered at the local municipal level (or by a third-party agency where a municipality has not opted in), so requirements for like-for-like replacements can vary by jurisdiction.
