Dyna Glo RA18LPDG Indoor Propane Heater Review

Heaters are used the world over, and they come as an alternate heat supply for our homes, offices and even outdoors. They come in many different types and makes, all cut out for people’s different tastes. They come in handy especially in time zones that experience seasons like winter. During the winter period, temperatures go way below zero degrees, and it is almost impossible for anyone to survive without an alternative heating system in their homes and offices. There are various ways for one to determine the sort of heaters that will suit their needs, and we are going to go through some of them before we get into the task of reviewing the Dyna Glo, RA18LPDG, 18,000 BTU Propane Cabinet Heater.

The Size of the Heating Area

This is a very important factor. One has to know the size of the area where they are going to use the heater. One cannot use a compact heater in a hall that needs bigger heaters. Knowing the size of the area will help you determine whether you’ll be buying more than one heater, or whether one big one will be enough.

Portable or Immovable

Heaters come in two types in regards to this point, portable and immovable/ fixed. Fixed heaters are those that cannot be moved around. They could be built into the walls of the house or be too heavy to carry around. These were the most common heaters back in the day. In these modern times, portable heaters have taken the market by storm. These are heaters that you can carry around with you at your convenience. If you want to go camping with it, all that you have to do is to make sure that it will provide enough for the tent or RV, make sure that it has gas, whether LPG or propane, or that there is a power outlet where you’re camping. Portable heaters are usually compact and light, making them easy to move around. They are also very easy to store in small spaces due to their compact sizes.

Source of Power

You need to determine the source of power for the heaters that you’ll be using. The three main sources of heat for the heaters are electricity, LPG and propane gas. Electricity was the most commonly used source of energy for the heaters in the past and then came LPG. Those two have been used for ages until propane gas was discovered. Propane gas is the most economical of all the three, and that is since the propane gas is made from things that are readily available like material waste. Propane gas also has an advantage over LPG because LPG emits more harmful gasses than propane gas. At the moment, propane gas heaters are the ones that are most commonly used in North America at the moment, and those are the reasons why.

Whether the Heater is for Indoor Use or Outdoor Use

The heaters can either be made for indoor use, outdoor use or both. You have to be very specific about the use of your heater before purchasing it. That is because indoor heaters might prove to be a hazard when used outdoors since it might not be suited for outdoor factors such as wind.

With the above factors in mind, we can now take a look at the Dyna Glo, RA18LPDG, 18,000 BTU Propane Cabinet Heater.

The wheels allow you to easily move the heater wherever you need it. When you find the right spot, the 2 locking casters ensure that it stays there.

The heater comes loaded with three adjoining burners, each rated at 6000 BTU. Each burner is either on or off, and each is controlled by the gas valve on top of the cabinet. Low setting is the center burner only. Medium is the left and center burners together, and high is all three on at once. Each burner has a ceramic element with many small holes that the gas flows through as it burns, heating the ceramic bright orange hot and putting out a lot of radiant infrared heat rays. Of course, there is also hot air rising from the burners too, and that contributes to warming a room. The radiant heat feels great, especially when you come in from the cold and want to warm your hands.

Some reviewers reported difficulty keeping the “pilot” lit. The pilot is actually an oxygen depletion sensor or ODS. It is designed and tuned so that if the oxygen in the room falls below a safe level the flame will go out, triggering the gas control to shut off the gas to the burners. The heater is not designed for outdoor use, and in fact the manual says it’s for indoor use only. If used outdoors, any breeze will blow out the exposed pilot, aka ODS.

This is generally a good heater to own. The manual says that it is not suitable for residential use, and that is probably because it is not vented. When it is new it will not produce carbon monoxide, but as it ages, it could start emitting the toxic gas. We would recommend using a carbon monoxide sensor when using the heater indoors.
