Choices for Gas Heaters

Ventless gas heaters have the ability to heat a room without the need to exchange outside air. This type of heater has no vent because it utilizes the oxygen in the room.  Through combustion, heat is generated and fueled by the oxygen in the room. These heaters work with both LPG (liquefied petroleum gas) and natural gas.
Some types of ventless heaters include the radiant heater, space heater, gas log version and blue flame. Each type has a unique system of combustion and heating. Ventless heaters are typically the preferred type of heater because of several advantages.
Advantages
Installation: With a ventless gas heater, there is no need for a chimney, external vents or flue. Therefore, the installation charges are minimal when compared to a normal wood or gas fireplace. Further, there are some units that are easily mounted on the wall with a nail.  There are also heaters that are stand-alone units which require no installation at all. These ventless heaters help to save money by reducing the need for costly installation.
Cost Effective: These heating systems are highly fuel efficient at a rate of 99.9 per cent, which means that there is little or no wastage in the gas consumption. Different to a natural gas space heater, the other heaters give off harmful emissions. Propane and gas heaters, on the other hand, burn the fuel steadily and do not produce harmful emissions such as carbon monoxide and smoke. They actually work better than traditional heaters and save you a lot of money. This fuel efficiency aids in reducing the need to refill often.
Environmentally Friendly: The ventless gas heaters utilize LPG and natural gas, which are clean fuels that are friendly to the environment. As mentioned previously, carbon monoxide is not produced so there are no threats to human beings. Actually, this heating system can be considered as an alternate heating source.
In addition to the benefits listed above, natural gas garage heaters have other advantages. Similar to room heaters, they are also highly efficient and offer fuel efficiency and a source of clean heat. This heater does not have a large air mover in the unit, which means there is no noise pollution. These heaters are actually portable and can be shifted from one location to the next including on trips outside of the home.
There are several different options available including the infrared garage heater. It also works with natural gas or propane. Its infrared technology is similar the way the sun warms the earth because it heats the surface.
