What Does Water Heater Replacement Cost?

Tank vs. tankless and propane vs. electric drive most of the cost difference. Here's what a real water heater replacement includes — and how to get a real number for your home.

We don't post a flat water heater price, because the number depends on tank vs. tankless, your fuel, the size your household needs, and what the install location requires. Here's what actually drives the cost, and how to get a real figure.

What a water heater replacement includes

A real replacement covers the unit, removal and disposal of the old one, water and fuel connections, venting (for propane models), any pan/drain and code updates, and a proper startup. Out here the fuel question is propane or electric — there are no natural-gas mains — and that choice shapes both the equipment and the running cost.

What drives the cost?

  • Tank vs. tankless. A standard tank is the simpler, lower-upfront install. A tankless unit costs more up front, supplies hot water continuously, and often needs upgraded venting or gas piping (or substantial electrical capacity for electric tankless) to install correctly.
  • Fuel. Propane models need venting and fuel piping; electric models need adequate panel capacity. Switching fuels mid-replacement adds scope.
  • Capacity. Sized to your household's real hot-water use — bathrooms, laundry, and how many showers run at once — not just "what was there."
  • Install location and code. Tight closets, crawl spaces, venting runs, expansion tanks, and pan/drain requirements all move the number.

How should I think about the range?

In plain terms: a like-for-like electric tank swap is the low end. A propane tankless conversion with new venting is the high end. Most replacements land in between. If your current heater is limping — rusty water, rumbling, moisture around the base — planning the replacement on your schedule beats an emergency swap at 6 a.m. on a Saturday.

What's not included — and what about incentives?

The federal 25C credit expired December 31, 2025 and is not available for 2026 installs, so we don't budget around it. Local co-op or utility rebates occasionally cover water heaters (especially electric models on co-op programs) but vary by who serves your address — confirm with your provider, and we'll help you check; see the rebates navigator. Financing is available; paying for a new system covers how the pieces fit.

Failure modes that cost you later

  • Buying tankless without pricing the venting/electrical the install actually needs.
  • Undersizing for a full household, then living with cold showers.
  • Waiting for the tank to fail — a burst tank adds water damage to the bill.

We look at your fuel, your household's use, and the install location, then give you upfront pricing with tank and tankless options side by side — including honest advice when the cheaper option is the right one. We're licensed, insured, EPA-certified, and family-owned.

FAQ

Frequently asked questions

How much does a new water heater cost?
It depends on tank vs. tankless, propane vs. electric, the capacity your household needs, and what the install location requires. A like-for-like electric tank swap is the low end; a propane tankless conversion with new venting is the high end. We quote a real number for your home with a free estimate.
Is a tankless water heater worth the extra cost?
It can be — tankless supplies continuous hot water and takes up less space, but it costs more up front and often needs venting, fuel-piping, or electrical upgrades to install right. For some households a properly sized tank is the better value. We'll price both honestly so you can compare.
When should I replace my water heater instead of repairing it?
Rusty water, rumbling or popping sounds, moisture around the base, or a tank well into its second decade are the classic signs. A leaking tank should be replaced promptly — a burst one adds water damage to the cost. Planning the swap on your schedule always beats an emergency call.
