During the colder winter periods, a gas heater will be very helpful to make your terrace, rooftop or balcony in Hong Kong comfortable. A patio heater (also called a mushroom or umbrella heater) is a radiant heating appliance for generating thermal radiation for outdoor use.
A burner on top of a post, burns liquefied petroleum gas (LPG), propane or butane, and directs the flames against a perforated metal screen. Heat is radiated from the surface of the screen in a circular pattern around the appliance. A reflector atop the burner reflects heat that would be otherwise lost upwards. This is because the reflecting hood is usually silvered which makes it a poor absorber/emitter of heat but excellent at reflecting infra-red radiation back. This reduces the amount of heat lost by conduction as silvered surfaces will not absorb infra-red light.
The GardenSun patio heater is now available at SofaSale.Propane patio heaters are the most popular type as they are portable and easy to find refill locations such as gas stations or convenience stores.
