Water heater replacement cost

How much does a water heater replacement cost?

The table is an installed price: the unit plus a normal swap of the same fuel in the same place. A 40-gallon electric tank starts from a national typical of $1,750. A 40-gallon gas tank starts at $1,950. A heat-pump water heater starts at $3,900. A gas tankless starts at $4,300. Your city then scales the labor. About 42 percent of that national price is the crew. Materials barely move, only a small nudge when local labor is higher or lower. The low column is 78 percent of the scaled typical. The high column is 134 percent. Low is an easy closet. High is the same heater plus a drain pan, an expansion tank, a flue fix, or a second trip.

Pick your city in the bar. A labor factor of 1.20 does not mean the heater itself costs 20 percent more. It means the hours cost more. The page for your city writes that gap in dollars for the electric tank so you do not have to do it in your head. If you have not picked a city, you are looking at a national crew priced at 1.00.

Which type you are actually buying

An electric tank is the common rental-building replacement and the usual low install price. It keeps costing you on the electric bill. A gas tank costs a bit more to install and usually less each month, if the flue and the gas line are already right. A heat-pump water heater costs roughly twice an electric tank to install and uses less electricity, which matters more when your rate is high. It needs air around it and a place for condensate. A gas tankless costs the most here because the vent and sometimes the gas line have to change. Do not compare a tankless quote with the electric-tank row.

What pushes a quote into the high column

Same fuel, same closet, existing vent, pan left in place: that is the typical column. A pan, an expansion tank, a new discharge pipe, a flue that fails inspection, a code correction, or a return trip is the high column. A re-pipe, a move to a different floor, or a conversion from electric to gas is a different project and can honestly sit above the high number. Ask the quote to list those lines. If it says “standard replacement” and the price is far above the high number, ask what was added.

If you rent

The price does not change. Permission does. You almost never replace a water heater on a lease. Use the range to read a landlord's number. An “emergency” that is several times the high column for a standard tank is a question, not a reason to hire someone yourself. Owners still need a written scope. The optional note under the result does not change the table.

Running cost is separate. At your city's planning electric rate, an electric tank bills you every month and a gas tank bills you mostly once. This calculator does not invent a payback or assume a rebate. Check the utility before you treat a heat pump as discounted. Reviewed 2026-09-01. The city page has the local constraint — basements, shared chimneys, tight closets — that a national table cannot see.

When you have a quote in hand, find your city page and read the local note before you decide the typical column is wrong. A shared chimney or a basement drain changes the job in a way a national table cannot see. The calculator gives you the band. The city page tells you which houses in that city tend to land high.
