With all needed parts and labor, hiring a plumber to install a traditional gas water heater costs $300-$3,500 or more, depending on capacity (with 40 or 50 gallons the most common sizes); length of warranty (typically 5-12 years); and the amount of repairs required to meet current building codes. CostHelper readers report paying an average cost of $948 for a 40 gallon unit (ranging $360-$2,800); an average cost of $1,211 for a 50 gallon unit; and an average cost of $1,937 for a 75 gallon unit (ranging $1,300-$3,588).
A tank-style gas water heater can also be purchased at a home improvement store, plumbing supply house or online retailer for $230-$2,000 or more, with installation done separately. Installation costs vary significantly depending on who does the work; the condition of the water heater hook-ups, and if any adaptations are needed to install a new, larger unit in the space. If extensive work is required, installation can cost as much as or more than the water heater. CostHelper readers report paying $70 -$1,706 for installation, for an average expense of $630.
An electric water heater can cost $400-$3,000 or more for complete installation of a conventional storage-tank model and $1,800-$4,500 or more for a tankless model (including a 220V/240V outlet). Electric water heaters typically cost less than gas units but are more expensive to operate.
Solar water heaters cost $1,000-$5,000 or more, with installation usually included in the purchase price.
A central, whole-house, gas tankless water heater can cost $800-$3,000 or more, without installation. Because tankless systems typically require the addition of a 220V/240V outlet and/or larger-diameter gas pipes than found in an average home, installation can bring the total cost to $1,800-$5,000 or more.

What should be included:

Generally, a one- to two-person household needs a 30-40 gallon water heater while a household of five or more needs 50-80 gallons. However, a tank that puts out more than the household uses hourly wastes money and energy heating extra water. Tankless systems avoid that cost and take up less space, but more than one unit might be needed to shower and run a dishwasher at the same time. The U.S. Department of Energy describes the different types of water heaters[1] .
Replacing an old water heater with a similar but updated model is relatively straightforward, but new and more-energy efficient units are often larger, and might not fit the existing space or hook-ups.
Check with the local planning department; a permit and inspection may be required. Replacement water heaters typically are required to meet current building codes, which may mean upgrading the existing water and gas lines, installing new valves and other parts, and the addition of an expansion tank[2] to minimize pressure build-up.

Additional costs:

Less expensive units may cost the most to operate. The U.S. Department of Energy explains how to estimate and compare water heating costs[3] .

Discounts:

Do-it-yourself installation is possible, but can be challenging. This Old House explains how to replace a water heater[4] , calling it a moderate-to-difficult project that takes 2-4 hours and requiring basic plumbing skills plus the strength to wrestle out the old unit and carry in the new one. CostHelper readers report paying $385-$750 for do-it-yourself installation of new water heater, at an average cost of $574, while a New Jersey reader reports paying $2,500 a plumber (triple the normal rate) to fix the botched do-it-yourself installation of a 40-gallon water heater.

Shopping for replacing a water heater:

Get several estimates. Request and check references, and be sure the company is properly bonded, insured and licensed.
A written contract should include a detailed outline of the work required and materials to be used, and dates within which the project will be done.
