Buying a new water heater is a burdensome expense, so naturally we look for the best deal possible — but it’s important to keep in mind that the cheapest water heaters to purchase are usually the most expensive to run. Here’s what you need to know before you go shopping:

Here are some tips to keep in mind when purchasing a new unit:
- Determine your fuel type – oil, propane and natural gas are cheaper to run than electric water heaters. If electric is among your considerations, call your utility company and ask about their off-peak electric rates when it comes to heating water. This is available through some utility companies and can make purchasing an electric unit more advantageous.
- The efficiency of a water heater is measured by its EF, or energy factor. The higher EF on the water heater, the more efficient that particular model is.
- Consider purchasing a Heat Pump Water Heater. Though these units are more expensive upfront, they can reduce your water-heating bill by up to 50 percent and are a great option for those who live in moderate climates.
- If you plan to purchase oil-fired or gas water heating units, be on the lookout for units that have sealed combustion or power venting features. These will prevent combustion gases from seeping into your home.
- If at all possible, do not put a water heater in an unheated basement. If this is the only location to install the unit, consider insulating the water heater. There are many techniques online to insulate, and most are quite inexpensive!
- Try to shorten the length of the pipes from your water heater to your kitchen and bathrooms as much as possible.
- FHR is the measure of how much hot water the heater can produce during a high-usage hour. Before you buy, Google "Estimating Peak Hour Demand/First Hour Rating," and look for a unit in the range of your worksheet total. Remember, water heaters with the biggest tanks do not always come with the highest FHR.
Save on running a water heater
Once your water heater is installed, follow these helpful tips to lower your usage:
- Check for any leaky faucets, showerheads and bathtub fixtures – you will pay $1 more per month for every leak that produces a drop per second.
- Decrease your water heater's temperature setting to 120°F. Also, keep an eye on temperature settings if you have an electric water heater; these usually contain two thermostats that control the lower and upper heating elements. Keep settings at the same level to prevent burnout or too high a workload for one element.
- Purchase and install low-flow showerheads or faucet aerators – these could potentially decrease your consumption of hot water by 50 percent.
- Approximately every three months, you should drain at least a quart of water from your tank. This will help remove any sediment that has collected (which causes the interruption of heat transfer, thus lowering the efficiency of the unit).
- Consider taking a shower over a bath; showers generally use less than 10 gallons of hot water per five-minute shower, whereas a bath uses between 15-20 gallons of hot water.
- Consider installing a hot water heater timer that shuts off your system at night and turns it back on in the morning. Within a few months, your timer has paid for itself!
