Upgrade to an ENERGY STAR certified heat pump – also called “hybrid electric”- water heater –, take advantage of existing federal and utility program incentives for making the switch, and start saving today!

How to get energy star for low income?

When available, these programs typically include a home energy assessment accompanied by direct install of energy saving devices including ENERGY STAR certified smart thermostats. Like LIHEAP and WAP, eligibility is usually based on household size and income in relation to a percentage threshold above the Federal Poverty Level or Area Medium Income (AMI). Depending on where you live, these programs may be working with state agencies who provide low-income services more broadly. A small but growing number of utility companies are paying for ENERGY STAR Home Upgrade packages, which customers pay back over time via a charge on your utility bill. This method of payment for upgrades is tied to location and will not follow you or your credit if you move. Importantly, the energy savings from the upgrades should result in a lower bill overall. Ask your utility what programs they offer to help you with the ENERGY STAR Home Upgrade.

Is an energy star water heater safe?

ENERGY STAR electric water heaters generate hot water with no harmful burning of fuel inside the home. They are easy to install and safer to operate with dramatically lower total carbon emissions. If your current water heater runs on gas, oil, or propane, switching to an electric heat pump removes a potential source of carbon monoxide (CO) and nitrogen dioxide (NO2) from your home. It can even help reduce ground-level ozone, a common pollutant in many metropolitan areas.

Learn more about financial incentives that may be available to you.

How to choose a water heater?

As a rule of thumb, you may want to choose a heater with a water tank that is larger than the one typically recommended for the size of your household , which will help you to avoid using the hybrid unit’s less-efficient high-demand auxiliary feature. A larger tank that fills with hot water overnight, for instance, will prevent a shortage during bathroom rush hour the next morning. Considering the long-term value of an HPWH, going bigger is worth the additional cost. Water heaters with smart thermostats that initiate heating during off-peak hours (when there is less demand for electricity use) have the added benefit of allowing you to take advantage of clean energy at a lower cost, while still delivering plenty of hot water when you need it most. They essentially act as “batteries” for storing clean energy, says Delforge.

How many gals does a water heater have?

Of all the appliances that compete for a homeowner’s attention, from vacuum cleaner robots to video-enabled door locks that double as security guards, the standard 50-gallon water heater is the most likely to be ignored. Hidden from view in the basement or a dark utility closet, the tall metal cylinder that heats water for our sinks and showers typically functions reliably for a decade or more with little or no maintenance.

Why isn't heat pump adoption widespread?

“It is the job of policymakers to provide the right incentives to help consumers and installers get more familiar with and excited about these advanced, healthy, climate-friendly technologies.” Right now, only 11 percent of homes in the United States use heat pumps for space heating and cooling. If this technology became the standard for people installing new ACs, we could see them in up to 44 percent of homes by 2032 .

How does HPWH work?

In contrast to conventional gas-fired heaters, which generate heat from pollution-spewing combustion, or electric heaters, which use the same type of mechanism found in a toaster, HPWHs use an energy-efficient compressor that gathers heat from the atmosphere and concentrates it in a water storage tank. The result: savings for the average four-person U.S. household of close to $350 a year on electricity bills, or $3,750 over the life of a typical HPWH, according to the Department of Energy’s Energy Star consumer website. (Actual savings will vary, depending on location and the municipal or private utility that supplies electricity to your home.)

What is the most common type of water heater?

Can a gas water heater vent to the outside?

Equipped with a fan-propelled exhaust system, the advantage of this gas water heater is its ability to vent to the outside either horizontally or vertically—up to 100 feet. This expands installation possibilities and means that you can more easily relocate your gas water heater. In addition, the water heater draws air in from the outside, rather than using ambient air for system functions. Energy efficiency is improved, and this model carries a uniform energy factor rating of 0.69—making it Energy Star qualified. 3

An In-Depth Look at the New Regulations

The recent changes in water heater standards mainly involve an increase in the energy factor ( EF) rating. EF ratings are based on how much hot water a water heater produces per unit of fuel consumed throughout an average day. Efficient water heaters offer a higher EF than less-efficient models.

Impact on Homeowners

As expected, these new water heater standards will have a tremendous impact once they’re set into motion. Here’s what you can expect from the average water heater that’s made after early 2015:

What You Need to Look For

Knowing what to do in this situation could prove a bit baffling, especially if you’re in the market for a new water heater. Fortunately, there’s plenty you can do to get yourself ready for the long road ahead.

How efficient is an electric water heater?

The minimum efficiency of electric resistance storage water heaters is about 0.90 (depending on tank volume), and the best available are 0.95 EF. We do not recommend the use of electric resistance water heaters due to the high operating costs. A new electric water heater uses about 10 times more electricity than an average new refrigerator! Fortunately, heat pump water heaters using less than half as much electricity as conventional electric resistance water heaters are now available from several manufacturers—use the Enervee Score or check the ENERGY STAR lists for detailed information. If you use electricity for water heating, consider installing a heat pump water heater. Look at how the costs compare over the life of a standard water heater in “Comparing the True Cost of Water Heaters.”

How long does a water heater last?

Most water heaters have a lifespan of 10–15 years. If yours is up there in age, have your plumber take a look at it and advise you on how much useful life it has left. If it’s in bad shape, replace it now before it starts leaking or the burner stops working.

What is a combination water heater?

Combination appliances feature a powerful water heater, with space heating provided as the supplemental end-use. Heated water from the water heater tank passes through a heat exchanger in a central air handler to heat air. The fan blows this heated air into the ducts to heat the home. Many combination systems of this type are available at low initial costs, but space and water heating efficiency is often less than that of conventional systems. Models incorporating a high-efficiency condensing water heater, such as the Polaris® by American Water Heater, are exceptions. These models realize efficiency gains over traditional equipment, at 90% combined efficiency. Another approach, introduced in the U.S. by Rheem, uses a tankless water heater as the “engine” for both space heating and hot water.

How much hot water does a demand water heater use?

The largest readily available gas-fired demand water heaters can supply about 5 gallons of hot water per minute with a temperature rise of 77°F (58° to 135°F, for example). 77°F is the basis for industry calculations. This would support two simultaneous showers, or a bit more if the hot water is “mixed down” with a lot of cold water. If you’ve installed a low-flow showerhead (see “Conserve Water” below) and won’t need to do a load of laundry or dishes while someone is taking a shower, then 4–5 gpm might be fine. But if you have a couple of teenagers in the house, or if you need hot water for several tasks, a demand water heater might require staging some uses.

What is hybrid gas water heater?

Hybrid gas water heaters. Broadly speaking, the term refers to water heaters with more than two gallons storage, but less storage than expected from output capacity. They feature a condensing burner smaller than used on whole-house tankless units and enough storage to have high first hour ratings.

How many gallons of water does a storage water heater use?

The energy efficiency of a storage water heater is indicated by its energy factor (EF), an overall measure of efficiency based on the assumed use of 64 gallons of hot water per day, regardless of tank size. The first national appliance efficiency standards for water heaters took effect in 1990. Updated standards, effective in 2015, are summarized in Table 6.1.

What is indirect water heater?

Indirect water heaters, when used in combination with new high-efficiency boilers, are usually the least expensive way to provide hot water (see “Comparing the True Costs of Water Heaters”). These systems can be purchased in an integrated form, incorporating the boiler and water heater with controls, or as separate components. Gas-, oil-, and propane-fired systems are available. Any form of hydronic space heating — hydronic baseboards, radiators, or radiant heat — can be provided by boiler systems.

How does hard water affect water heater efficiency?

As water is heated, these minerals crystallize and settle to the bottom of your hot water heater, creating a sediment that reduces efficiency and over time slows down your water heater. Proactively draining your water heater’s tank once or twice a year according to your manufacturer’s instructions can help keep your tank sediment-free and running efficiently.

How to save energy on water heater?

For maximum energy savings, try insulating your water storage tank and exposed piping so heat is not lost as just-heated water moves from the water heater onward to its destination. Insulation blankets are relatively inexpensive and can have a big impact on your energy bill! Just be careful not to cover the thermostat for electric tanks, or the water heater’s top, bottom, thermostat, or burner for gas tanks.

What temperature should a water heater be?

The factory preset for a hot water heater is typically between 130-140°F.

Whether it’s taking baths or shorter showers, using cold water wash cycles when laundering clothes, or using the energy-efficient setting on your dishwasher, less warm water use means less utility costs! ...

Can you turn off your water heater overnight?

If you have a standard tank water heater, it’s constantly busy keeping a tank full of hot water to your specified temperature 24/7. That’s a lot of expelled extra energy, especially when you consider your household is asleep for one third of the day! A simple volt timer can be installed to an electric water heater to turn your water off overnight, saving energy and costs.

Do tankless water heaters run?

Unlike a traditional water heater, tankless water heaters only run while you’re actually using the hot water. Traditional water heaters provide hot water by heating water and then keeping it hot, cycling on and off to keep the water stored in a large reservoir warm for hours at a time even when you’re not using it.
