Space Heater Reviews

Space heaters are popular during the winter months because they can save tremendous amounts of money on the household electric bill. Instead of turning up the temperature for the entire house, a space heater allows you to keep the central or gas heat at a lower temperature and add heat to the room you are occupying. With hundreds of heaters available on the market today it can be hard to select one that will do the job. Finding a heater that is a good quality heater and safe is important. We have selected the best heaters for home use to help with your search.

Space Heater Buying Guide

Space Heater 3

When the tough gets going, the going gets tough. Space heaters are heaven sent when central heating is too pricey and not sustainable or if it doesn’t provide adequate warmth. For shifting climates that dwindle on cold and hot extremes, space heaters are most ideal. If you only plan on heating only one room, then a space heater is perfect.

Buy a space heater with a good conservation heating. It just means it’s better for the environment and less damaging to your budget in the long run. It commonly runs from 10,000 to 40,000 British Thermal Unit (Btu) per hour. BTU is the amount of energy needed to raise one pound of water by 1 degree Fahrenheit. Burning coals typically range from 9,000 to 12,000 BTU per pound. Therefore the higher the BTU, the faster it can heat up a space. Space heaters run on propane, kerosene and natural gas and should only be handled by adults as these are toxic and highly flammable gases. All space heaters identify themselves using BTU.

How do space heaters work?

Space heaters work in two ways: either heating the room by convection or by radiation. Using convection, space heaters regulate the air it touches and heat is distributed through the flow of air. This is suitable when the room to be heated is large or has a larger volume. Consider the size of the room. A small room with a high ceiling requires more BTU to heat up than a room with the same floor area but with a low ceiling.  Under radiation, space heaters quickly warm up anything within its line of sight using infrared light. Space heaters that use radiation are excellent for people that will stay or sit near the space heater. They also conserve energy better because it warms up the immediate people and the objects in front of it rather than circulating warmth throughout the entire room. Radiant space heaters are also ideal for people with dust allergies since air does not circulate actively.

Space heaters can be unvented or vented. Unvented combustion space heaters are harmful since they emit unwanted gases like carbon monoxide and nitrogen oxide. Unvented kerosene heaters are banned in some states. Vented space heaters are installed indoors but they have a duct that leads to a wall outdoors so that the fuel vent can be released. When buying vented heaters, look for the mark “100% indoor air” and “sealed combustion.”

Caution should be exercised. Aside from its use of propane, kerosene and natural gas, the U.S. Consumer Product Safety Commission has reported 25,000 residential fires that are associated with space heaters. In addition, around 6,000 people are treated in the hospital due to burns incurred from contact with hot surfaces of room heaters.

For liquid-fueled heaters, use only the designated fuel. If it runs on propane, never use kerosene, unless permitted by the manufacturer. Let the heater cool down before refilling it. Do not store the fuel near the heater.

Catching up with modern times, electric space heaters are also available. They are also available as convection or radiant space heaters. They look refreshingly sleek and can be mounted on the wall. There are space heaters specially made for smaller rooms (10’x12′). Some are even equipped with low carbon dioxide emission. Electric space heaters are more expensive to operate and are the only unvented space heaters that are safe to use. The cord should be directly plugged to a wall outlet. If using extensions are necessary, choose only a 14-gauge wire or higher. Follow the manufacturer’s guide when using extension cords. For models that are not wall mounted, look for a tip-over safety switch. This will shut down the device once it has been accidentally tipped over.

The following are some guidelines when purchasing space heaters

Before purchasing, measure the size of the room. Measure the length and the width of the room then multiply them. The result will be the surface area in square feet (ft2). Measure the height of the ceiling, too. Then allot 10 watts per square foot. Simply multiply 10 watts to the area (ft2). You now have an idea how many watts it needs to heat up your room. Now convert this to BTU. 1 watt is equals to 3.41 BTU. Simply multiply 3.41 by your resulting wattage. Now you have the amount of BTU needed to heat up your room. Now for the final step, estimate the number of windows and insulators of your room. Windows will let the heat escape and insulator (like mattresses, pillows, wood) would keep heat. Consider the size of the ceiling you measured earlier.

Now you’re armed with an approximate knowledge of how many BTU your room needs to be adequately warmed up, consider your lifestyle.

Who would use the space heater? How often would it be used? At times, it would be a matter of budgeting at this point. Is a few dollars savings worth sacrificing a few watts?

Always make sure that it complies with Underwriter’s Laboratories (UL) standards. Their logo would be on the box or directly on the space heater’s sticker. Purchase only current models. If possible, look for thermostatically controlled space heaters because these models can avoid energy wastage by lowering its power output upon detecting once the room has reached the ideal temperature. It may be tempting to buy a big heater for a small room thinking that you could save energy by setting a lower temperature output, but don’t. It requires more wattage to start and power up.

A very important word of caution never ever place space heaters behind or near curtains. Also, do not position space heaters where there is high foot traffic such as hallways or junctions in the hallway. Place flammable chemicals away from space heaters, regardless if they could spill easily or in closed bottles. Do not leave children alone with space heaters. Extra caution should be regarded if you have roaming pets at home. Lastly, when leaving the room, turn off your space heater.
