No matter what the source of energy is, water heaters have the potential to use a ton of it. To conserve energy and use it efficiently, you may want to look into green water heaters.
Conventional Water Heaters
Many models of conventional water heaters waste around 20 percent of the energy they use. The majority of the heat they produce escapes through the tank since most of the heated water sits unused around the clock. This process is known as standby loss, which you don’t want to happen. Wasted energy is not efficient. Along with being inefficient, conventional water heaters do not last as long as other options. (To find the correct size of water heater for your home, check our water heater sizing guide.)
Hybrid Water Heaters
Hybrid water heaters work by pulling heat out of the air around it, then pumping it into the tank. These types of water heaters are efficient for those who live in warmer climates. Hybrid heaters also have the lowest operating cost of any type of electric water heater out there. However, a hybrid heater pump costs way more than any other type of water heater and the water heater size depends on how well it will work.
Tankless Water Heaters
Tankless water heaters provide hot water at all hours of the day, every day of the year without the standby loss of your average water heater. This happens because tankless water heaters generate hot water as it is needed instead of storing unused, pre-heated water. A water sensor detects when the faucet is turned on and then sends a message to the water heater to begin heating. This process reduces energy bills up to 50 percent, according to the U.S. Department of Energy. However, tankless water heaters tend to have a three to five second lag before the water heats up.
Heating water accounts for a huge portion of the electricity used in your home. But there are plenty of options for green water heaters out there to help you conserve energy and reduce water-heating costs. For a more eco-friendly water heating experience, opt for an alternative that isn’t heating water 24 hours a day.
