FAQ
Which water heater is more cost-effective long-term?
Gas water heaters are more economical. Based on Hong Kong rates, gas heaters can save approximately 30-50% in annual operating costs compared to electric models, though initial installation costs are higher.
Can I install a gas water heater in an older building without gas supply?
It depends on whether the building has a main gas line and complies with safety regulations. Contact your gas company for assessment. If unavailable, an electric heater is the practical alternative.
