What is a Gas Heater
Quite often we do need an additional heating source - whether to spend more time outdoors or warm up a cold room - and this is where gas heaters may come in handy.
Gas heaters are portable devices fed by natural gas. They don't need the power supply and are fueled through the connection of special gas tanks. There are home gas heaters used in private houses and apartments, garages, workshops, etc. The outdoor gas heaters let you get warmed and enjoy the fresh air on a terrace, in a summerhouse and cafe during the cold season. There are also the gas heaters designed for industrial facilities and heating of big areas.
What Features to Compare
Before choosing a gas heater, you need to take into account some important features specified below.
The performance of a gas heater is the first thing you should pay attention to. The performance depends on the type, heating capacity, and heating range. There are several types of gas heaters: catalytic heaters, forced air heaters, and radiant heaters.
Catalytic heaters are used for auxiliary or centralized heating of various facilities, including cottages, workrooms, and garages. These heaters feature catalytic panels that are used as heating elements. Catalytic panels consist of glass fiber with inclusions of platinum powder. Thanks to such design, there are no harmful combustion products and foreign odors. In addition, the gas consumption is low, so the catalytic heaters can also save you costs. A catalytic heater with the heating capacity of 3.000-4.000 BTU will be enough to warm the area of nearly 200 square feet.
The forced air heaters are powerful heating units that provide quick and efficient warming of large rooms and premises, as well as open and semi-open areas over 1000 square feet. They are mainly used in industrial buildings and warehouses, car workshops, hangars, agricultural facilities, etc.
The radiant heaters are widely used for warming terraces, summerhouses, sidewalk cafes, etc. These heaters are commonly used outdoors since the harmful combustion products are emitted during the heating. A radiant heater with the heating capacity of 40.000-45.000 BTU is able to warm the air in the range of 10-20 feets.
The runtime of a gas heater depends on the capacity of a connected gas tank. The more fuel is supplied, the longer a heater will warm the air. For example, the indoor heater with a 20-pound gas tank will be warming your room for 100 hours and even more. Yet, the outdoor heater with a gas tank of the same capacity will provide heating for 8-10 hours.
Next, you need to take into account the usability of a gas heater. The ease of use of a gas heater is largely determined by the principle of ignition. Currently, gas heaters feature two types of ignition: piezo and electronic. When you start a heater with piezo ignition, you need to press a button on the front panel actuating the built-in piezoelectric element that generates a spark and ignites the burner. Once the heater is started, it is enough to simply turn the control knob to get the warmth in a few seconds. The gas heaters featuring electric ignition are turned on with a special button or control knob generating the spark. The heaters equipped with electronic ignition are distinguished by a high reliability even in severe working conditions, therefore, they are widely used at different industrial sites. The multiple operating modes, adjustable heating direction, and connection of gas tanks of different capacity also facilitate the use of heaters.
Finally, it is very important to pay attention to the safety of a gas heater. Using gas heaters are very much like having an open fire at home, so there's always a risk factor. However, most gas heaters have an extensive safety feature set to eliminate a chance of firing or burning. The safety features include automatic safety tip-over and low-oxygen shut-off functions, protective grates, and carrying handles or wheels for transportation and storage, etc.
