All water heaters provide a heating source for water passing through your main lines. Some heat that water only when you "call" for the water at one of the home's faucets while others keep a storage tank of heated water at the ready. There are also a variety of methods of heating the water including electric, oil, gas, and thermal heat. A heat pump water heater has a storage tank heated by heat taken from the surrounding air. Here are some of the pros and cons of heat pump water heaters.
Pro: One of the Most Energy Efficient Systems
A heat pump water heater doesn't require utilities such as electric or gas to create its heat. The system is therefore one of the most energy efficient systems on the market second only to solar-powered heat. A heat pump system can save about 65% of energy compared to the minimum energy efficiency standards the United States government requires for a water heater to be deemed Energy Star efficient.
The energy efficiency and non-reliance on electric and gas can help slash your utility bills and improve your household budget. This also means that your water heater will still work perfectly fine if there is a temporary outage in one of those utility services.
Pro/Con: Similar Lifespan to Standard Water Heater
Tanked water heaters tend to have shorter lifespans than tankless units because the water inside the tank will eventually erode the interior and require a new tank. A traditional tanked water heater has a lifespan of about 8 to 10 years while a tankless has about 20 years. The heat pump water heater has a lifespan near the upper end of a traditional tanked water heater.
If you are set on getting a tanked water heater, then a heat pump's slightly longer life than a standard tanked water heater might be a big selling point. But if you're looking for the most long-lasting system as your primary objective, you would be better off going with a tankless setup.
Con: Only Works in Mild to Hot Year-Round Climates
Heat pump water heaters need warm air to function. If the tank has that warm air supply, it can keep producing virtually unlimited hot water for your home. But if the weather cools down significantly, you won't have any hot water supply.
Heat pump water heaters are therefore only recommended in areas that have mild or hot climates regardless of the season. If you live in an area with more temperamental weather and still want an efficient setup, consider a solar system. For more information, talk to a professional like Brother's Plumbing.Share
