The Pros and Cons of Heat Pump Water Heaters

Are you considering getting heat pump water heaters for your residence? If your water heater needs repair or even a replacement, then you may have seen heat pump water heaters as one of the many options available for you and your home.

Heat pumps have been in use since they were invented in the 1940s. While they rose to popularity in the 1970s, many homes still rely on traditional electric or gas heaters to get hot water. That’s why we put together this complete guide on heat pump water heaters and all you need to know about them when making this decision. 

All About Heat Pump Water Heaters

How it Works

Many homeowners may overlook the importance of a good water heater and the surprisingly high price tag of having hot water. The average family spends $400 to $600 a year on the luxury of having hot showers and warm water. This price is partly because conventional water heaters are famously inefficient; they can account for up to 20 percent of your entire utility bill. That’s why many homeowners are switching to heat pump water heaters and other energy-efficient options.

Before deciding on a heat pump water heater, you should know how they work. While most water heaters rely on gas or electricity to generate heat, heat pump water heaters are different – in fact, these pumps don’t generate any heat directly. Instead, they pull heat in from the air, which is then delivered to the unit’s storage tank. This process is how refrigerators work, but heat pump water heaters do the reverse while a fridge expels hot air. Because they’re pulling in hot air, this makes them ideal for primarily warm climates like Louisiana!

The Pros and Cons

Pro: Heat Pump Water Heaters Are More Efficient

Since they can draw from the heat in the air, these water heaters do not have to work to generate new heat. Instead, this heat comes from anywhere in the air, even the waste heat from a nearby furnace. Because of this, they are incredibly energy efficient compared to traditional models, which means they can save you several hundred dollars on energy bills each year, and they’re long-lasting –  a good, well-maintained heater can last between ten to fifteen years. 

Con: Greater Up Front Expenses

These water heaters can cost up to twice as much as other models, which can be a setback for those working on a tight budget. The cost can range from around $2,100 to $3,300 upfront, not including installation. While these heaters can still save you money over time with annual energy costs, the initial price is enough to push it out of some buyer’s budgets.

Pro: Environmentally and Family Friendly

Since they don’t generate heat, gas leaks and toxic emissions are non-existent from heat pump water heaters. Plus, the unit itself doesn’t get too hot outside, making it a safer option for families with pets or kids.

Research has shown that if all residential electric water heaters were replaced with heat pump water heaters, the energy cost savings would jump to $12 billion annually, and 140 billion pounds of greenhouse gas emissions would be prevented annually. That’s the equivalent of emissions from 13 million vehicles, which is more than the entire population of Los Angeles.

Con: Can Be Difficult in Cold Climates

Heat pump water heaters draw from the air, so when there’s plenty of warm air (say, in the summer months), there’s no problem. However, this can take more time during colder winter months. Unless it’s a hybrid model that includes electric options, you have to give it time for your pump model to recover. However, this isn’t as much of a problem in subtropical climates like the American South, where plenty of warm air is nearly year-round.

Other Options

  • Tankless water heater: This is an increasingly popular choice for those who want energy efficiency without the high upfront cost. The tankless water heater doesn’t store heated water in a large tank like most options – instead, it heats water just as needed, so it’s available only on demand. The benefits of a tankless water heater are that the smaller units require less storage and improved energy efficiency, so you save money on your energy bills. This option is ideal for a smaller home or space or smaller families who don’t need hot water as often.
  • Solar water heater: Solar water heaters harness the Sun’s energy, utilizing roof-mounted solar panels that transfer energy directly to the water heater to heat the water. These have many advantages, including saving money on your electricity bill, offering tax credits in certain areas, and being environmentally friendly. Unfortunately, solar power is unreliable as it requires regular access to sunlight. You can still collect solar energy on cloudy days, but repeated days with low sunlight can negatively affect your heater’s effectiveness. Solar power is an excellent option for some households but is not a one-size-fits-all solution.
  • Conventional style water heater: Among the most popular water heater options, the traditional water heater is a design that has yet to go out of style. Usually, these heaters have a large insulated water tank heated by a heat source, typically a gas flame. These heaters are generally very cheap compared to alternatives, effective in all climates, and are easy to service because of their simple design. There are two downsides to this design that has allowed space for heater innovation; however: they take up a lot of space, and they waste a lot of energy. Additionally, this design typically requires access to natural gas, which may not be available for some areas or be expensive for others. 

How to Extend Your Heater’s Life Span

 When you’re spending large sums of money on a water heater, it’s in your best interest to take the steps necessary to extend that heater’s life cycle for as long as possible to avoid purchasing a new one.

  • Invest in a quality heater. The best way to ensure you get your money’s worth out of your water heater is to invest in a quality one. If you seek out the cheapest water heater on the market, the chances are that you will get what you pay for and end up needing to purchase a new one before you would normally. 
  • Get your heater serviced regularly. As with any home appliance, you should aim to get your heater serviced regularly. These heaters should be serviced by a plumbing professional at least once a year. This is to ensure the longevity of your heater and the quality of your hot water. Goodbee Plumbing offers many different services for all of your plumbing needs.
  • Use cold water when possible. It may seem obvious, but a great way to extend the life of your water heater is simply to use it less frequently. You never have to go without hot showers, hot sink water, or otherwise- instead, wash your clothes with cold water when you can, and consider using your stove to heat water for cooking-related purposes. 
  • Install a timer. Water heaters typically stay on for the entire day, which may be a waste of electricity. Instead, consider hiring a professional plumber to install a timer on your water heater, allowing it to heat water only during the hours it will be used. Timers when used effectively, can add years to any heater’s lifespan.
