Need a new water heater or just looking to increase the operating efficiency of your current one?

Water heating is typically the second largest energy expense in your home. Heating your water typically accounts for about 11% of your utility bill. An old water heater can operate for years at very low efficiency before it finally fails.

Many homeowners wait until their water heater fails before shopping for a replacement. This is unfortunate because the cost of purchasing and operating a water heater can vary greatly depending on the type and model selected as well as the overall quality of the installation.

What To Look For In A Water Heater


Family Needs

The size of your family and the space available for your water heater play an important part in determining the type of water heater that is best for you. Regular demand capacities are based on a home with a washing machine and an automatic dishwasher. High demand capacities meet the hot water needs of teenagers, whirlpool tubs, spas, and oversized baths. Always anticipate your family’s future needs when selecting your water heater.

Household Size Demand Gas Electric
5 or more Regular 50, 60, or 75 Gallon 80 Gallon

High 75 Gallon 120 Gallon
3 to 4 Regular 40, 50 Gallon 50 or 65 Gallon

High 40, 50, 60, 75 Gallon 80 Gallon
2 or less Regular 30 Gallon 40 Gallon

High 40, 50 Gallon 50 Gallon

Types of Water Heaters

Both gas and electric storage tank water heaters operate in similar ways and range in size from 20 to 80 gallons. When you turn on a hot water faucet or use hot water in a washer or dishwasher, water pipes draw hot water from your tank. The heated water is drawn from the top of the tank and is replaced by cold water that is carried to the bottom by a tube.

An electric water heater can be used most anywhere, whereas a gas water heater is usually installed in a home that already uses gas.

Tank Size and Recovery Rate

The size of your tank (the number of gallons of water held) is an important factor to consider in your purchasing decision. When determining the size of your tank, consider the number of people in your household. If you have 2 people in your home a tank size of 30 to 40 gallons is good. If you have 5 or more in your household you may want to look at a tank size of 50 to 80 gallons.

Another consideration in your purchasing decision is recovery rate (number of gallons of water that can be heated in an hour).

Dimensions

What are your space considerations? Know the dimensions where your water heater is located. Determine the height of your current water heater as well as the diameter. This information will help you understand the space constraints associated with upgrading your tank. Also, it is important to know the wattage of your current water heater (i.e. 3500w or 4500w).

Energy Efficiency

The energy efficiency rating should be on a sticker on all water heaters. The efficiency and operating costs should go into your purchase decision.

Do It Yourself Tips


Don’t take the comfort and convenience of having hot water in your home for granted.

Service Tips

Bathing, showering, doing the laundry or dishes would be unpleasant without it. Not to mention the expense of unexpected breakdowns.


Here are some general tips to extend the life of your water heater:



  • Lower the thermostat on your water heater; water heaters sometimes come from the factory with high temperature settings, but a setting of 115 degrees provides comfortable hot water for most uses.
  • Drain a quart or more of water from your tank (until the water runs clear) every month or two to remove sediment that impedes heat transfer and lowers the efficiency of your water heater.

Do-It-Yourself Tips

Do it yourself tips

There are several ways to cut your water heating bills: use less hot water, turn down the thermostat on your water heater or buy a new, more energy efficient water heater. A family of four, each showering for 5 minutes a day, uses 700 gallons of water a week; this is enough for a 3-year supply of drinking water for one person. You can cut that amount in half by using low pressure showerheads and faucets.


  • Repair leaky faucets promptly. A leaky faucet wastes gallons of water in a short period.
  • Install aerators in faucets and low flow showerheads

What You Need to Know

Each county in Maryland requires that a permit be issued for a water heater installation.

Certain counties require a thermal expansion tank with the water heater. A thermal expansion tank has a sealed-in compressible air cushion, which will compress as thermal expansion occurs in the water heater. The thermal expansion tank provides a space to hold and store the additional water volume.
