Most water heaters typically rely on gas or electricity to generate heat, but heat pump water heaters are very different. In fact, they do not generate any heat directly at all. Instead, they transfer heat from one place to another to get the job done — but how does that work?
Heat pump water heaters actually pull heat from the surrounding air. This is then delivered to the water in the unit’s storage tank.
Heat Pump Water Heater Pros and Cons
By sheer design, heat pump water heaters are very energy efficient. Rather than having to work hard to generate heat, they work by drawing existing heat from the air surrounding them. As a result, when compared to a conventional electric water heater, heat pump water heaters can be two to three times more energy-efficient. Besides, with the heat pump water heater, you won’t have to worry about gas leaks or other toxic emissions. Also, because it doesn’t generate heat, the unit itself won’t be hot on the outside, making it a safer option.
Your upfront costs for a heat pump water heater will be undeniably higher, but think about how much less you’ll be spending on annual energy costs. Within just a few years, the unit could actually pay for itself, leaving you a decade or more of savings. If you can afford it, a heat pump water heaters might be a wise investment, but it won’t be in everybody’s budget.
