Getting Started

During the winter months, cold air always seems to find a way into your home, and with it comes the inevitable increase in your energy bills. If you have an area of your home that tends to be colder than the rest, whether this is caused by a drafty window, or due to a lack of central heating returns, enlisting the help of a space heater this winter, can help you save energy and money.

Space Heater Size & Coverage

As you being to decide which type of space heater is right for you, take into consideration what size will suit your needs best. Consider if you are going to be using the space heater to heat an office or bedroom, a large family room or great room, or just your feet warm at night. This will give you an idea of what space heater will be ideal for your needs. Be careful to take into consideration that if you buy one that is too large it may waste energy and in turn unnecessarily raise your electric bill.

The standard form of measurement for gas heaters is British Thermal units or (BTUs). When selecting a space heater, look for the wattage necessary to heat your specific area, then simply multiply that number by 3.41 to convert it to BTUs (1 watt X 3.41= BTUs). For Example: If you have an enclosed outdoor patio that measures 15' X 10' the Square Footage would be 150 sq ft. An area that is 150 sq ft would require 1250 watts to heat. So take 1250 and multiply it by 3.41 and you will need a heater that provides 4262 BTU's.

Keep in mind that your geographical location will play a big role in how much energy your heater will consume. For instance, say you live in the most northern states of America, then your heater will need to consume more energy in order to properly heat, than if the heater was being used in the southern most states.
