Construction and Design

Shopping for a gas heater? There are certain features you need to check for when selecting a suitable heater for you. Before purchasing a specific portable gas heater, consider the following features in its construction and design:

  • Type – There are two common types of portable gas heaters on the market. Consider buying a convection heater if you want your room to be evenly heated. These types of heaters don’t heat exposed heater surfaces, making them safer for use in homes with young children. They rely on natural hot air movement and fans to speed up operation. However, they can be noisy.
    • Convection gas heaters have thermostats, sensors and remote controls for more effective use. Infrared or radiant-convection heaters are quieter and easier to maintain. They’re also known to achieve targeted heating. They operate by heating a specific surface, which radiates infrared rays.
    • Gas heaters cost less than their convection counterparts. On the downside, though, they have no timers, remote controls and thermostats. These heaters are operated manually with buttons.
  • Fuel – Consider the type, safety, and availability of fuel a heater uses. Portable gas heaters use propane, natural gas, or kerosene. The fuel is clearly indicated on each heater, as it’s hazardous to use the wrong gas type with any gas heater.
  • BTU Output – Each portable gas heater has a specific heat output. Consider the size of room or space to be warmed. The higher the BTU output, the more heat is released into the environment.
  • Coverage Area – Each particular heater has a coverage area that it can heat effectively within a specified time. There are models designed to warm enclosed rooms indoors, and other models for outdoor use.
  • Safety – Safety precautions for both the user and heater should be clearly indicated on user guides. Gas refill procedure, cleaning and care directions should be observed at all times. Modern models have a range of safety sensors. In case there’s a low supply of oxygen, the flame gets extinguished, or the heater tips over, it will automatically turn off.

Performance and Ease of Use

Buy portable gas heaters from popular brands that have been in use for a longer time. You’ll be assured of quality and portability with gas heaters that have passed the test of time. It’s advisable to shop around and make product comparisons before making a purchse. Since portable gas heaters run on natural or LGP gas, make sure your rooms are well ventilated for good air circulation.

Avoid using gas heaters in small rooms, bedrooms, or bathrooms. For longer quality service, a portable gas heater should come packaged with a clear user guideline. A technical manual comes in handy if you need your heater to be repaired by your local technician. Check for a warranty agreement, in case your portable gas heater has non-reparable manufacturers' defects.
