Gas Space Heater
A Gas Space Heater can come in handy to heat smaller spaces where there is no electricity. However, some models can be larger and used to heat the entire house. The smaller models can either be mounted on the wall, stand alone, or portable. These are pretty cheap ranging from just under $100 to upwards of a few hundred dollars. Wall mounted gas space heaters will either run on natural gas, propane, or can be switched between the two using a conversion kit. Make sure the conversion kit is included to make life easier when choosing a model. Some rely on electricity to power the fans, so keep that in mind when picking which one is good for your needs. Others run on liquid kerosene. Here's a few different types of gas space heaters available on the market today.
Portable Gas Space Heaters: Portable gas space heaters are great for the outdoorsman, patio, garage, shed, or other outside or cool workspace. There are a couple different types of designs when it comes to portable gas heaters. The tank top mount- These heating devices mount directly on top of a propane tank. These are pretty portable, keeping in mind that they will weight as much as the propane tank you decide to attach it to. Some will have a single heating unit that attaches to the top, while others will be larger and have 2 or more heating units that attach to the top. The hose to heater- These models have a hose, sometimes up to 10 feet, that attaches to the propane tank. These can be light-weight or much larger to heat larger areas, but they are still portable. The handled heater- There are some models that come in a box type design with handles on it. These are the ultimate portable models and can be taken anywhere. Make sure to get a model that can take a beating and is sturdy.
Forced Air Gas Space Heater: These types of gas heaters are a little more powerful as they force the air away from the heating unit with a fan motor. Some of these models will rely on electricity as well to power the fan, however other models are completely free of electricity dependence. These forced air gas heaters can really pump out the heat, and they come in varying powers and sizes. The very large ones can really get expensive, but can heat entire indoor and outdoor areas. This could be perfect for those winter construction sites, cold large rooms such as factories, and other various uses. Smaller forced air gas space heaters are perfect for bringing different places and really pump out the heat as well. Some of these models will be a forced air space heater if you can plug it into electricity, but will still emit heat when the power goes out and the fan can't be operated.
Kerosene Gas Space Heaters: Kerosene gas heaters can come in a variety of designs and models for different uses as well. There are obvious drawbacks to the kerosene models because filling and transporting the kerosene can get a little messy. However, the good thing about these models is you don't have to attach it to a large propane tank like some of the propane models. Kerosene gas space heaters are convective heaters so they heat portions of the room surrounding the heater, versus a radiant heater which will have a more pronounced warm and cool side.
Floor and Wall Mounted Gas Space Heaters: There are many models that are not meant for portability per se, but are more for putting directly on the ground in a garage, on a patio, etc... These often will have the ability to be plugged in so a fan motor can run. However in the event of a power outage the gas space heater still heats the area. It just will be more of a natural heating effect versus being blown into the surrounding area.
