Are All 1500 Watt Heaters The Same?

A 1500-watt heater is good if you are looking for a supplementary heat source for small indoor spaces. A standard 1,500-watt heater is powerful enough to provide supplemental heat in rooms that measure up to 150 square feet and have standard ceiling heights.

If you consider other factors such as the house’s insulation, then the heater can provide enough heat to warm rooms that are larger than 150 square feet in size.

Do All 1500 Watt Heaters Heat the Same?

Every heater has a unique heating method and capacity. There are three basic types of heaters: oil-filled, ceramic, and infrared. The performance of any 1,500-watt heater depends on which type it is.

1,500-watt heaters that fall under the category of oil-filled heaters provide heat via the convection method. They have oil-filled tubes that are used to transfer heat energy to air currents.

The warm air currents then flow around the entire room through the convection process. It takes a few minutes for the whole room’s ambient temperature to rise to the desired levels.

1,500-watt heaters that fall under the ceramic heaters category have a unique heating element to generate the heat. The ceramic heating element automatically regulates its heating performance according to the temperature of the surrounding environment. Some ceramic heaters have oscillating heating elements for the effective distribution of heat.

1,500-watt heaters that fall under the infrared category are the most efficient ones. They have quartz tubes or tubular elements that generate infrared radiation. The radiation is transferred to all objects within a room. This mode of heating creates a comfortable indoor environment instantly.

How Much Does it Cost to Run a 1500 Watt Heater for 24 Hours?

To determine the cost of running a 1,500-watt heater for 24 hours, you need to understand the amount of watt that it consumes every hour and the price of a kW of electric power.

A 1,500-watt heater consumes an average of 1.5kW per hour. A kW is a unit of measuring electricity. One kW is equivalent to 1,000 watts. Therefore, if you run it for 24 straight hours, the heater will consume 36kW of electric power.

Although the price of electricity, expressed in kW, varies, we can assume that it is 10 cents per kW. Therefore, the cost of running a 1,500-watt heater for 24 hours is the product of 36kW by 10 cents, which is $3.6. Please note that this cost changes depending on the prevailing rate of kW at any time.

How Many Amps Does a 1500 Watt Heater Draw?

A standard 1,500-watt heater operating on the high heating mode draws 12.5 amps of electric current. Amps, which is the short form of amperes, is a unit measuring the rate of electric current flow.

If you place such a heater on the same home circuit with other devices with massive wattage and amperage needs, it is easy for the circuit breaker to cut the electric current flow. This usually happens when the entire circuit is overloaded.

What Size Room will a 1500 Watt Heater Heat?

In principle, a heater rated 1,500 watts should sufficiently heat a room that does not exceed 150 square feet in area. A general rule of thumb is that one needs 10 watts for every 1 square foot of space.

However, in practice, a 1,500W heater may effectively warm spaces larger than 150 square feet. Similarly, heaters that are rated 1,500W may fail to adequately warm rooms that measure 150 square feet in area.

Some of the critical factors that influence the relationship between a heater’s capacity and the area that it can effectively warm are the height of the ceiling and the level of insulation of the house.

If a house is over insulated and the temperatures outside are not very cold, then a heater rated 1,500 can prove to be too big for a house that measures 150 square feet. A 1,500 heater can end up heating vast spaces that are appropriately insulated and have standard ceiling heights.

Will a 1500 Watt Heater Heat a Garage?

Most garages have a lot of open spaces near the doors and other apertures. Such areas increase the garage’s heating requirements because a lot of heat is lost to the outside.

Cold air drafts keep flowing into the garage, thus creating an endless cycle of cold currents that need to be heated continuously by the heater. Therefore, heating a small garage may be a bigger challenge than warming the air inside a large living room in your house.

However, remember that your 1,500W-rated heater can effectively warm the air in your garage. Small garages designed to host only one car and have a little extra space are more straightforward to warm than large ones, designed to hold three cars.

Things to Consider When Choosing a 1500 Watt Space Heater

It isn’t easy to choose the right space heater for your needs because many brands have different performance features on the market. However, here are a few tips to guide you when selecting the right space heater.

  • Safety features. Go for heaters that have safety features, including overheat and tip-over protection. Using such heaters reduces the risks of fires and shocks.
  • The noise levels. The action of the fan usually generates noise in a heater. Therefore, heaters that have inbuilt fans are noisier than those which do not have fans. Check your heater’s noise level so that it does not cause distractions when operating because of producing much noise.
  • The heater’s design determines how well it can be used to blend with your interior décor style. Consider what you would like to achieve with the heater before deciding on the right model to buy. Also, consider whether you would like to have the heater mounted on the wall or used in the standalone mode.
  • It is always necessary to move heaters from one room to another in the home. Heaters that have handles and caster wheels are more portable than those which lack these features.

Safety Tips When Using Space Heaters

The most common risk of using a space heater is the outbreak of a fire. Heaters can start fires because of several reasons. The most common one is when a heater gets into contact with highly combustible material such as fabrics and paper. Also, your heater may cause a fire if it overheats.

Another common risk of using heaters is the internal components getting damaged. If the internal temperature of a heater rises abnormally, then the internal parts may get damaged.

Lastly, heaters can cause burns if kids, pets, or even adults touch their hot surfaces. Therefore, preventing these and other related risks forms the basis of safety tips for using heaters.

  • Plug your heater directly into the wall socket. It is unwise to use extension cords with your heaters because the cords may not sustain your space heater’s amperage and wattage needs.
  • Shut off the heater when it is not in use. Ensure that you shut off and unplug your heater when you are not using it. Doing this reduces the chances of the occurrence of accidents related to electrical faults and overheating.
  • Keep your heater dry always. Avoid touching your heater if your hands are wet. Unless your device is specially designed to be used in humid conditions, keep the heaters away from bathrooms and other wet places in your house. When water gets into contact with electrical devices, it can cause shocks.
  • Conduct regular maintenance procedures. The occasional cleaning and inspection of your device may go a long way in ensuring that everyone in the home is safe. If you detect a problem with any part of your heater, please contact a technician. They will assess the risk that the fault causes.

Tips for Positioning Your Space Heater

It would help if you placed your heater correctly for maximum heating and safety. The following tips can help you ensure that you get maximum heating from your device and use it safely.

  • Keep the heater at least 3 feet away from combustible materials. Some of the most flammable materials at home include clothes, rugs, chairs, and beddings. If they touch the hot surface of your heater, they can cause fires. If you place your heater under the window, then ensure that the curtains neither touch nor are near the heater’s surface.
  • Place the heater on a level and hard surface. Doing this avoids instances of the heater often falling. Although most modern space heaters have the tip-over protection feature, it is not advisable to allow them to keep falling to the ground.
  • Position your heater at a strategic place so that the heat distribution is maximum. This applies to standalone as well as wall-mountable heaters.
  • Do not place objects on the top of the heater. Heaters are not designed to hold other objects on the top. More so, the top surfaces of some heaters get quite hot. Placing objects at the top of the heaters increases the risks of fires. This is true if the objects are made from combustible materials.
