If you’ve read a blog post by our co-founder, you know that we’re committed to making affordable housing accessible to everyone. To do that, we need to keep costs down from day one. One of the easiest ways to save money is to replace your old hot water tank with a new energy-efficient model. The average cost of a new water heater is between $1,500 and $3,500, but you can expect to save between $400 and $900 every year on your water and heating bills with an ENERGY STAR water heater. Here are some tips on how you can save money on your hot water tank:

Shop Around for the Best Price

When you replace your water heater, you’ll likely buy it from a contractor or a home improvement store. You’ll want to ask them to give you a price quote, and then compare it to the prices you see online. You should also ask for written guarantees on the parts and labor, and make sure they stand behind their work. If you can, go to a dealer that belongs to a national contractor’s association. These dealers have agreed to abide by a code of ethics that includes transparent pricing and high standards of customer service.

Go Green with a Low-Head or Tankless System

If you’re in a rented apartment or a home that doesn’t have sufficient space for a larger water heater, a low-head or tankless system could be the right choice for you. These systems run on a simple electrical circuit, and they’re much less expensive to install. The downside is that they’ll only run when someone turns on the faucet to draw water. If you live in a household with frequent water use (like families with children), however, a low-head or tankless system could be a good fit. The reason is that a tankless system can only be activated by the flow of water, not by a faucet being turned on. If you only have occasional guests, a low-head water heater could be an ideal solution for you.

Go with an Energy-Efficient Program

If you replace your water heater with a new ENERGY STAR model, you’ll not only save money on utilities; you’ll also be doing your part to reduce greenhouse gas emissions. But you don’t have to replace your old water heater just because a new one is more energy-efficient. You can retrofit an old model with an ENERGY STAR control, which will allow you to adjust the water temperature remotely. If you have a home with a natural gas or oil-fired water heater, it can be retrofitted with an alternative fuel control. There are several ENERGY STAR program options available to help you retrofit your water heater.

Go with a Smart/Self-Controlled Water Heater

If you have an electric water heater, you may decide to convert it to a smart or self-controlled model. These water heaters can be programmed to use less energy when you’re running a laundry or a shower, and they can be operated remotely. They’ll also be easier to repair if something goes wrong. In addition to the energy savings, you’ll also be able to save money on water. If you’re in a building that has a building management system, you may be able to access your water meter remotely from your smart phone. This means you can set your water temperature to a lower setting if you’re on a budget, or if you’re a resident who’s on a water restriction.

Don’t forget the other costs of replacing your water heater

It’s important to keep in mind that when you replace your water heater, you may also have to replace your sewer and/or drain lines. You’ll also need to hire a plumber to connect your new water heater to the incoming line. If you have a septic system, you may have to replace the septic tank, too. When you make these replacements, you may also have to pay to have your old pipes and tanks properly disposed of. If you have a new water meter installed, you may also have to pay to have that installed. If you’re in the market for a new water heater, ask your contractor about any other costs you may have to pay.

Bottom line

The bottom line is that you can save money by replacing your old water heater. The most efficient models are ENERGY STAR certified, and they’ll be more cost-effective than an older model. If you’re replacing an old, inefficient water heater, you’ll also be reducing your carbon footprint. These are two great reasons to replace your old water heater.

Frequently Asked Question

While you technically can install a hot water heater yourself as a homeowner, the likelihood that this is a good or safe idea is very slim. Trust the professionals with your hot water heater installation to make sure it's done correctly. You wouldn't want to cause yourself or your family any harm.
The higher cost is a result of a more labor-intensive set-up, as new gas and water lines are required for installation. For a new tankless water heater, new electric wiring will need to be installed.
Turn off all water supplies in the house. Turn on all the hot water faucets in the house in order to drain what is left in the existing hot water heater. Then, disconnect the water line that connects the water heater to the rest of the house. There is often a connection on a hose that you can simply unscrew.

120 degrees Fahrenheit is the safety recommendation against scalding, but 140° is the common default setting. Most experts agree that anything below 120 degrees creates a risk for bacteria to develop inside your water heater from stagnant water, such as legionella that causes Legionnaire's disease.
These heaters can be fueled by electricity, gas, or liquid propane and installed in many areas of your home. The national average cost to replace a 50-gallon hot water heater is $1,100 to $2,800, with most people paying around $1,800 for a direct replacement of a 50-gallon gas hot water heater using the same model.

Turn up the thermostat on the hot water heater. One of the easiest ways to make a hot shower last longer is by using less hot water while it's at a higher temperature. To do this, turn up the temperature on the thermostat that's attached to the hot water heater tank. (Not the thermostat on the wall.)
