1. Environmental adaptability
The air source water heater derives its heating capabilities from the surrounding air, an essential resource. To determine its energy efficiency, manufacturers consider the COP value and energy-efficiency ratio. These heaters are marketed for their energy-saving benefits, and its performance is closely linked to these factors. Typically, air-energy water heaters operate best between temperatures of 0-40°C, making them ideal for regions with high temperatures such as the south. However, in areas with freezing temperatures like northern cities where temperatures drop as low as -10°C, such heaters struggle to function correctly. Even at -20 ℃, these heaters fail to start and require alternative heating methods such as electricity (akin to a large electric kettle) during winter months when temperatures dip.
2. Air energy water heater installation problems
Air-energy water heaters used in households typically need a water tank to store hot water. For a family of 3-5 individuals, a water tank sized between 120L-150L is recommended. However, installing such a large tank can be challenging as it may clash with the aesthetics of the house. As homeowners become increasingly focused on crafting an inviting and comfortable home environment, many are hesitant to place such a bulky unit on their balconies. Consequently, they must explore alternative installation options.
3. Consumer awareness of heat pump water heaters
The heat pump water heater is a relatively new technology in the domestic market, and unfortunately, awareness of this product is still very limited among consumers. Many people are skeptical about the idea of getting three parts of heat with just one part of heat, which has also resulted in low awareness of other products related to thermal recovery technology. Although heat pump air conditioners are quite popular, people tend to think of them as just big power consumers. However, they are actually much more energy-efficient than traditional coal-burning stoves. Despite this fact, many large shopping malls have yet to carry air-energy water heaters, further contributing to the low awareness of this innovative technology.
4. The purchase cost is very high
Investing in an air energy water heater may have a higher upfront cost compared to buying multiple gas water heaters. However, the long-term savings from reduced electricity or gas bills over a period of seven to eight years can offset this initial cost. Furthermore, the energy efficiency of an air energy water heater makes it a more environmentally friendly and sustainable option. In the end, it is an investment worth considering for those who want an energy-efficient and cost-effective water heating solution.
