Types

Water heaters can use natural gas, propane or electricity for fuel. Newer tankless models have become popular, and can be purchased nearly anywhere traditional tank water heaters can be found.

Retail

Home retailers such as Home Depot, Lowe's and local hardware stores carry a variety of water heaters. The sales associates can assist you in selecting the right water heater for your home, and most stores offer delivery to your home with a nominal fee.

Professional

Some plumbers, as well as heating and air conditioner repair professionals, can supply and install water heaters that are in stock at their facility. The choices available are often limited when purchasing from a professional, though they can typically install the unit at the point of delivery.

Online

Online retailers such as Amazon.com and websites for home improvement stores like Sears.com and Lowes.com offer a wide variety of water heaters. Buying online is a good option for those who know exactly which water heater they need or want the option of comparing models, though shipping for units purchased online may be a hefty cost.

Used

Local classified advertisements may offer good deals on water heaters. Contractors and homeowners may sell water heaters when they replace their unit with a bigger or more efficient model.
