One of the most common patio heaters available is the natural gas heater. Indeed, it has been in existence for a long time – long enough for companies to enhance its features to make them easy to use, simple and cost-effective to maintain, and above all, safe.
An outdoor natural gas heater uses natural gas, or liquefied petroleum gas (LPG) to generate heat and warm up the interior of the home or the outdoors. The first commercially once was made in 1856. They used the principle of heat convection to spread the locally heated air around the room. It operated like a simple Bunsen burner, the same principle still being used today in the mushroom-type outdoor heater. Most of today’s modern outdoor gas heaters utilize infrared technology to spread radiant heat more efficiently than others.
Natural gas patio heaters come in two main classes; those that are permanently attached to pipes or gas tubing, or those that uses gas tanks (though these can also be connected to pipes). The most common design is the mushroom-type form. These particular styles are available in both fixed and portable models.
The Mushroom-type model typically consists of a large diameter reflector cap placed over the main heating assembly. The heating assembly itself is attached to the pipes leading to the main gas line. The distance between the ground and the base of the heating assembly is around 1.5 meters on the average. This is usually enough to cover up to 5 meters (or around 16 feet) of circular radiant heat. A large base insures the stability of the assembly. For fixed natural gas heaters, the pole and base assembly can be thin and stylish with no additional bulk. A non-fixed heater typically has a bulk in the base to store the LPG container. These are ordinarily quite durable and weather resistant, although a good heater cover would do it a lot of good.
A new class of natural gas heaters are emerging that can be mounted on walls or ceilings. These types come in relatively small sizes which can be fitted on almost any patio design.
Safety features, however, are critical design features that accept no compromises. With natural gas heaters there is typically some danger involved with mishandled installation as well as faulty products.
However, these new class exemplify top quality components as well as a full complement of safety features designed to fill you with a sense of ease and comfort while using these products. Features like a fully automatic on/off system for wall mounted models, anti-tilt system that automatically shuts off the flow for the flame in the unlikely event if it gets knocked over. There are models that keep track of the carbon monoxide emissions as well as oxygen content in the air and prevent the heater from operating before it reaches unsafe levels.
The availability of fuel, together with new safety and convenient features added to a proven technology all combines to an excellent outdoor heater. With natural gas heaters, style, comfort, safety and convenience are all packaged in one affordable product.
