Water heater replacement cost calculator
Replacing a water heater is one of the bigger jobs in the home, and the price swings a lot depending on the type, the fuel, the tank size and how much plumbing or venting has to change. Set the options below for a realistic ballpark, supplied and installed, before you call around for quotes.
Price up a water heater replacement
Tank (storage) units are usually the cheapest to install. Tankless costs more up front.
Heat pump (hybrid) units cost more up front but run far cheaper.
Bigger households need more hot water, which means a larger tank.
A like-for-like swap in the same spot is the cheapest and quickest job.

What goes into the price
A water heater quote is really two things added together: the unit itself and the labor to install it. A straight like-for-like tank swap in the same spot is the cheapest and quickest job. The price climbs when you move to a tankless or heat pump unit, go up in capacity, or when the installer has to relocate the heater, run new gas or water lines, or add venting and a permit.
Choose your heater type and fuel, set the capacity, and say whether it is a like-for-like swap or a relocation with new lines.
See a low-to-high cost estimate and a typical mid-point, so you know the ballpark to budget for and what a fair quote looks like.
Use your range to brief two or three licensed plumbers and ask each to look at the job and quote in writing.

Estimate = base unit and install + type + fuel + capacity + work Why two quotes for the same heater look so different
The job is rarely the same twice
Two homes with the same heater can be hundreds of dollars apart. A garage swap with easy access is cheap labor, an awkward closet relocation with new gas lines, venting and a permit is not. The unit type and warranty, the capacity you need, and how much has to change all move the number, which is why a range is more honest than a single figure.
The job goes to the plumber who answers
When a water heater fails, most homeowners call three or four plumbers and book the first good one who actually picks up. The ones who miss the call lose the job to whoever answered. Hey Jodie answers every call 24/7 for plumbing and HVAC firms, takes the details and books the visit - so urgent jobs do not slip away while the tech is on another call. It books jobs and captures enquiries; it does not give out prices.
Frequently asked questions
How much does it cost to replace a water heater? +
For most homes a water heater replacement supplied and installed lands somewhere between about 1,000 and 2,500. A straight like-for-like tank swap is at the lower end, while a tankless or heat pump unit, a bigger capacity, a relocation or extra work like new venting and a permit pushes it higher. Set the options above for a ballpark closer to your own home.
What affects the price of a new water heater? +
The main drivers are the type (tank or tankless), the fuel (gas, electric or heat pump), the capacity you need for the size of your household, and how much the installer has to change. A like-for-like swap in the same spot is cheapest; relocating the heater, running new gas or water lines, adding venting and pulling a permit all add to both the unit and the labor.
How much more is a tankless water heater than a tank? +
Tank (storage) heaters are usually the cheapest to buy and install. A tankless or on-demand unit typically costs a good deal more, often a thousand or two above a comparable tank swap, because the unit itself is pricier and it often needs new gas or venting and upgraded water lines. A heat pump (hybrid) unit also costs more up front but is far cheaper to run.
Is this water heater cost estimate accurate? +
It is a realistic ballpark based on typical 2026 supply-and-install prices, meant for budgeting and for sense-checking the quotes you get. It is not a fixed quote. Your real price depends on your exact unit, your home and the condition of your existing setup, so treat the range as a guide and get a survey before you commit.
How do I get an exact quote for a water heater? +
Use the range here to set your budget, then ask two or three licensed plumbers to look at the job and quote in writing. A proper quote should list the unit make and model, the warranty, the labor, and any extras like venting, a permit, an expansion tank or new lines. Compare like for like rather than just picking the lowest headline number.
Does the estimate include removing the old water heater? +
Yes - the base figure assumes a standard installation that includes taking out and hauling away your old heater and installing the new one in the same place. Extras that are not always included, such as a permit, new venting, an expansion tank or relocating the unit, sit on top, which is why the higher end of the range exists.
