Hot water heaters account for a significant portion of home energy use, so it’s important to choose an energy-efficient model when replacing an old unit or buying a new one.
Here are 10 tips to help you select the most efficient hot water heater for your home.
1. Decide which type of hot water heater is best for your home.
There are three main types of hot water heaters: tankless, solar, and conventional storage tanks.
Tankless models heat water on demand, so they are more energy-efficient than conventional storage tank heaters. Solar hot water heaters use the sun’s energy to generate heat, so they are also very efficient.
2. Consider the size of the unit.
Hot water heater efficiency is measured in gallons per minute (GPM). The larger the unit, the more water it can heat per minute. However, a larger unit will also cost more to purchase and install. Choose the largest unit that meets your home’s hot water needs without going over your budget.
3. Look for an ENERGY STAR® label.
ENERGY STAR is a government-backed program that helps consumers save money and protect the environment by identifying energy-efficient products. Hot water heaters that have earned the ENERGY STAR label are at least 20% more efficient than standard models.
4. Compare annual operating costs.
In addition to the purchase price, consider the annual operating costs of different hot water heater models. Operating costs are typically expressed in terms of cost per year or cost per month. To compare operating costs, divide the total annual cost by the number of gallons of hot water produced each year.
5. Consider installation costs and incentives.
Installing a new hot water heater can be expensive. Make sure to factor in the cost of installation when choosing a new unit. Some utility companies offer rebates or other incentives for installing energy-efficient hot water heaters. Check with your local utility company to see if any incentives are available in your area.
6. Get professional help to choose the right model.
A qualified contractor or plumber can help you select the most energy-efficient hot water heater for your home and install it properly.
7. Consider future needs when selecting a new hot water heater.
If you plan to sell your home in the near future, it may be worth investing in a more expensive, high-efficiency model. High-efficiency models typically have a higher initial cost, but they can save you money over time in energy costs.
8. Make sure the unit is properly sized.
An improperly sized hot water heater can be less efficient and may not meet your home’s hot water needs. A qualified contractor or plumber can help you determine the right size for your home.
9. Install the unit in the proper location.
Installing a hot water heater in an unheated space, such as a garage, can reduce its efficiency. If possible, install the unit in a heated space, such as a basement or utility room.
10. Insulate the unit to reduce heat loss.
Adding insulation around the tank and pipes can help reduce heat loss and improve the unit’s efficiency.
Choosing an energy-efficient hot water heater can save you money on your utility bills and helps protect the environment. There are a number of factors to consider when selecting an energy-efficient hot water heater, including the type of fuel it uses, its size, and its Energy Factor (EF).
When selecting an energy-efficient hot water heater, it is important to consider the type of fuel it uses, its size, and its Energy Factor (EF). You should also look for a unit that has earned the ENERGY STAR label. Additionally, installation costs and incentives should be considered when choosing a new hot water heater. A qualified contractor or plumber can help you select the most energy-efficient hot water heater for your home.
When choosing an energy-efficient hot water heater, it is important to consider the type of fuel it uses, its size, and its Energy Factor (EF). Natural gas is typically the most affordable option, followed by electricity. Propane is usually the most expensive option. A larger hot water heater will typically be more energy-efficient than a smaller one. Hot water heaters with an EF of 0.90 or higher are considered to be very energy-efficient.
