Hongkongers have become accustomed to air conditioning, yet remain indifferent to heating. In summer, they rely on air conditioning for survival, while in winter, they endure long, damp nights indoors. Ironically, the city possesses the highest density of air conditioning units globally, yet many households still depend on oil-filled electric heaters for warmth. This regressive habit is not only energy-inefficient but also unsafe and unnecessary.<\/p>\n\n\n\n
Even more concerning is that the health risks of winter in Hong Kong have never been taken seriously. Multiple medical studies indicate that the winter mortality rate in Hong Kong is consistently 10-20% higher than in summer. During cold snaps, the overall mortality rate can spike by 20-30%, with the most vulnerable being the elderly, who often have low muscle strength and body fat, making them particularly susceptible to the damp cold. While severe cold is rare in Hong Kong, ‘cold’ here acts more like an invisible threat: subtle yet deadly.<\/p>\n\n\n\n
However, the electric heaters that Hongkongers commonly rely on are fundamentally inefficient resistive heating devices. Their performance is perpetually stuck at a 1:1 ratio; for every unit of electricity consumed, they generate only one unit of heat. They heat slowly, consume a lot of electricity, and occupy precious floor space in already cramped homes. When viewed in this light, these drawbacks make them a decidedly irrational choice, yet they have become standard equipment in many households during winter.<\/p>\n\n\n\n
Meanwhile, the split-type air conditioner, often viewed as a summer appliance, has undergone significant technological advancements. In essence, inverter heat pumps can extract heat from the outdoors and provide heating efficiency of 3-4 times. In other words, for every unit of electricity consumed, they can generate 3-4 units of heat, something that oil-filled electric heaters can never achieve. This is not mere speculation; it is the energy mainstream being promoted in mature markets like the UK, Europe, and Japan.<\/p>\n\n\n\n
Inverter technology also significantly enhances cooling efficiency. Traditional fixed-speed air conditioners operate on a crude cycle of ‘run at full power, then stop,’ which inherently wastes energy. In contrast, inverter units adjust their operation based on load, consuming 30-50% less electricity than fixed-speed models. In a city like Hong Kong, where electricity costs are high and living spaces are limited, such energy savings can substantially alter living costs.<\/p>\n\n\n\n
Space is also a critical factor. Oil-filled electric heaters obstruct movement in winter and have no place to store in summer, while wall-mounted heat pumps do not take up floor space and can be used year-round. Hong Kong homes simply do not have spare square footage for inefficient old appliances.<\/p>\n\n\n\n
The core issue has never been about ‘which machine to buy,’ but rather ‘whether our mindset has evolved.’ Hongkongers frequently need to replace their air conditioners, yet some still opt for models that only provide cooling to save money, only to purchase electric heaters later when they feel cold in winter. This practice is no longer justifiable in a city where energy is expensive, the population is aging, and winter mortality rates remain high.<\/p>\n\n\n\n
Hongkongers should stop purchasing air conditioners that only cool. Every time they replace a unit, they should switch to inverter heat pumps, allowing their homes to truly enter the modern age.<\/p>\n","protected":false},"excerpt":{"rendered":"
