The ideal water heater minimizes your energy use while providing hot water as needed and for as long as you like. But are energy-saving water heaters capable of doing that? Yes, they can, thanks to technological advancements.
Manufacturers previously rated a water heater’s energy efficiency using the High Efficiency (EF) ratings. The Uniform Energy Factor, a new industry standard, has, however, taken the place of previous ratings (UEF). For Energy Star certification, conventional electric and gas water heaters must have a UEF value of 0.65 to 0.95. Heat pump water heaters often have a UEF rating over 2.75 as a point of comparison.
Heat pump types are incredibly energy-efficient because water heaters consume up to 60% less electricity than traditional ones.
You’ve come to the perfect place if you’re looking for a new energy-efficient water heater. We’ll discuss several aspects of water heaters you should be aware of and what makes the most energy-efficient types.
Which type of water heater is the most energy efficient?
Before determining which type of water heater is the most energy-efficient, we’ll review five popular heater types.
- Conventional Water Heater with Storage Tank:
The most prevalent kind is conventional water heaters with storage tanks. A maximum amount of hot water can be stored in these water heaters before the tank needs to be refilled and heated. As a result, it is not the best choice for prominent families or those who anticipate using a lot of hot water quickly. Their energy factor ranges from 0.67 to 0.70. The efficiency of electric water heaters is at least 0.90.
- Heat Pump (Hybrid) Water Heater:
HVAC unit Water heaters, commonly called hybrid water heaters, utilize heat from the earth and the air around them to warm the water inside the tank rather than generating heat themselves. As a result, the only purpose of electricity is to transport water from the water heater to its final location. This water heater is highly efficient, but because the pump is located at the top of the tank, it needs a fair amount of vertical space. Heat pump devices are 2-3 times more energy-efficient than traditional water heaters.
- Tankless Water Heater:
As you might have guessed, tankless water heaters lack a tank. Instead, the device’s coils superheat it when the water travels through the mechanism to its final destination. One of the most energy-efficient ways to heat your house is on-demand hot water that rarely runs out. They consume between 24 and 34% less energy than standard water heaters or households that use up to 41 gallons of hot water per day.
- Solar Water Heater:
Solar water heaters heat water by harnessing the energy of the sun. However, solar panels on your roof power a heating system that heats your water to the proper temperature rather than absorbing heat. This is one of the most energy-efficient water heaters on the market right now because it doesn’t draw any power from the electric grid. However, solar water heaters typically rely on a backup power source to provide hot water when it’s stormy because not every day will be sunny. The cost of heating the water should decrease by 50–80% with such a unit.
- Condensing Water Heater:
A condensing water heater is perfect for households that predominantly utilize natural gas as a power source since it uses the heat exhaust from natural gas emissions. Similar to a traditional water tank heater, this tank uses extra natural gas rather than electricity or gas power. This tank uses very little extra energy to bring hot water where it needs to be. Condensing units can save up to 30% on energy expenses and have an energy efficiency of about 95%.
New water heaters: Are they more effective?
As new industry standards are introduced every few years, modern water heaters are far more energy-efficient than the previous models. Generally, manufacturers raise the heat exchangers’ efficiency rating and add insulation to water heaters. New units are also being created. For instance, solar systems that harness the power of the sun and heat pump water heaters that may transport heat from the air to the water.
Which is the most Efficient Gas Water Heater?
When your water heater vents out hot gas, it loses some heat if it is powered by gas. Thanks to modern gas-condensing features, this is now a needless waste of energy. Since gas condensers capture all of the exhaust and reuse it as heat, your water heater loses almost no heat. Additionally, these appliances offer superior insulation and more effective burners.
Which is the most Efficient Electric Water Heater?
One of the most energy-efficient electric water heaters available today is a hybrid or heat pump water heater. To transport heat, such systems do need electricity. The system is 2-3 times more energy-efficient than conventional electric water heaters because it doesn’t require electricity to generate heat.
How to Make Your Water Heater a Part of Your Energy-Saving Plan?
We hope you can make your decision with more assurance now that you know what kind of water heater is the most energy-efficient. Purchasing an energy-efficient water heater and other high-efficiency appliances helps reduce the need for non-renewable energy sources in everyday living.
