🚿 How Much Does Water Heater Replacement Cost in 2026?

Water heater replacement is one of the most common plumbing bills — and one where pricing varies widely. Here is what to expect in 2026:

Water Heater Replacement Costs

• Standard 40-50 gallon gas tank: $900 to $1,800 installed
• Electric tank (40-50 gallon): $700 to $1,400 installed
• Tankless gas water heater: $1,500 to $3,500 installed
• Heat pump water heater (hybrid): $1,500 to $3,000 installed — qualifies for federal tax credit up to $600

What Should Be in the Quote

A complete quote should include: the unit with model number specified, labor for removal and installation, haul-away of the old unit, new supply lines and fittings, permit fee, and expansion tank if your system requires one (most newer homes do). Ask specifically about the expansion tank — many plumbers quote without it and charge for it as an add-on.

Red Flags

Same-day urgency pressure. In most cases you have 24 to 48 hours to get competing quotes. A "price good until end of day" is a sales tactic.

No model number specified. Without the exact make and model, you cannot verify quality or compare quotes accurately.
