Avoid Unvented Gas Heaters 1. Unvented space heaters are more efficient than vented space heaters, because none of the heat output goes up the flue. All of the heat output (as well as the combustion gases) stay in your living room. 2. The gains in efficiency are not worth the risks to your health.

- Space Heaters. What is the importance of a space heater and what affect does it have on warranty? Electric motors frequently have space heaters installed, at the customer’s request, to prevent moisture condensation in the motor when it is not running. In applications where the possibility of condensation is not a factor, or where continuous operation of the motor prevents the formation of condensation, space heaters are not necessary.

What Is the Most Energy Efficient Space Heater Electric heaters may convert electricity fairly efficiently, but generating electricity itself is a fairly inefficient process. Overall, electric heaters will be less efficient than petroleum-fuel heaters. This is why most central home heating systems use natural gas or petroleum gas whenever they are available.

- Portable space heaters are small, electric resistance heating units. Regardless of the shape, size or type of electric heating element found in an electric space heater, virtually all power drawn is converted into heat. The cost of operating an electric heater depends on how much heat the unit is delivering.ortable space heaters are small, electric resistance heating units.

Great Lakes The lakes contained in 2009 84% of the surface freshwater of North America; if the water were evenly distributed over the entire continent's land area, it would reach a depth of 1.5 meters (5 feet).hough the five lakes reside in separate basins, they form a single, naturally interconnected body of fresh water, within the Great Lakes Basin. The lakes form a chain connecting the east-central interior of North America to the Atlantic Ocean.

Avoid Unvented Gas Heaters With an unvented gas space heater, the combustion process is very complete — 99.9% efficiency or higher, according to manufacturers — but that tenth or hundredth of a percent can be pretty nasty, containing constituents as carbon monoxide, nitrogen dioxide, soot, and unburned hydrocarbons.

Convection heater A convection heater may have an electrical heater element, a hot water coil, or a steam coil. Because of the natural ventilation, they are quieter in operation than fan heaters. The Model “S”, here as illustrated in 1924, is an example of an early model convection space heater, by the Sala Heater & Mantel Co. in Dallas, Texas. The Model S was considered to be highly efficient radiant type of gas heater at the time.

What Is the Most Energy Efficient Space Heater Heat Output. The most efficient space heater is one that's sized appropriately for the space it's being asked to heat. The heat output of space heaters varies widely, typically between 10,000 and 40,000 British thermal units per hour, and higher heat output comes at the cost of higher energy usage.

Itâs coldâ¦The dangers of electrical portable heating! It’s cold…The dangers of electrical portable heating! Electric space heaters can be an economical choice for providing warmth to small spaces. They are convenient, portable and, unlike fuel-burning heaters, do not give off deadly carbon monoxide. However, electric space heaters can be very dangerous if not used properly. Nationally, the number two cause of fires in the home and the number three cause of fatal home fires is heating equipment. It’s important to be careful with heating equipment, especially portable heaters. During this time of year when portable heaters are being used at work and home, we may forget the dangers that they pose the danger of igniting combustible materials. 1  To prevent physical injury (or death) and damage to property, you should be aware of the dangers and take precautions when using these heaters. Electric Shock. 1. Like all electric appliances, electric space heaters can cause accidental electric shock.
