Types Of Heaters For 500 Square Feet Rooms

The following are the common types of space heaters for 500 square foot spaces available in the market.

  1. Convective heaters: These are electric space heaters with inbuilt fans that blow heat around the room. Though these heaters take a little time to heat a room, they can maintain the room temperature for a long time once the temperature setting is reached. They could be a bit noisy because of the fan.
  1. Fuel-burning heaters: These heaters require propane, natural gas, or wood to produce heat. They do not consume any electricity but are tedious to install and maintain. These heaters are also space-consuming and may not be suitable for small 500 ft rooms unless for a short monitored period.
  1. Radiant heaters: These space heaters give out infrared radiation and direct heat. They heat the room fast and maintain the warm temperature for a longer period. Some radiant heaters are inclusive of blowers and oscillation features, which help in distributing heat evenly.
  1. Oil-filled heaters: These heaters follow the science of transferring heat energy to oil. The filler oil helps evaporate the accumulated heat, and the oil soaks in the heat and releases it slowly, heating the room.
  1. Radiant floor heaters: These heaters have a heating element in the pipe and are based on a structure of pipes and electric heating elements or any fluid. Steam heaters produce steam when water is heated. The steam is then channeled through a network of pipes, facilitating the heating of larger surface areas.

How To Choose The Right Heater For 500sft?

These are some factors you should keep in mind when buying a heater for a 500sft room.

  1. Sizing charts and calculators:You can refer to the heating chart for the number of watts or how much heating is required for various room sizes. Ideally, a 500sqft room will require a 4000w motor. A BTU calculator can tell you about the amount of heat required in the room and the passages.
  1. Room insulation: Rooms that are heavily insulated require lesser heating power. Usually, one square feet area requires 10w power, but an insulated room can do with 7.5w.
  1. Ceiling height and windows: The general rule adhered for heating measurements takes an average ceiling height of eight feet. If your ceiling is lower or higher, your heating requirements will vary accordingly. Windows usually are responsible for a loss of heat of 25%. Take these factors into consideration when buying the heater.
  1. Outside temperature: If the outside temperature is freezing, the heating drops pretty quickly. It also takes longer to heat the room. If you stay in a place where the temperature falls below 20⁰C, increase your heating calculation to 15w per sq. ft.
  1. Safety functions: The heater should have a thermostat for temperature control and auto power-off when overheating and tip-overs.

Janna Robinson, an interior designer and lifestyle technology design expert, says, “I would recommend making sure the heater is compatible with your space. Consider ten watts of heating power for every square foot for optimal heating and coverage. Also, factor in the noise level, safety features, warranty, and energy efficiency when choosing a heater.

Frequently Asked Questions

1. Are room heaters worth buying?

Modern-day heaters are economical, portable, and safe to use. Depending on the size of your room, you may opt for an oil-filled, radiant, or panel room heater. An oil-based heater’s flame is covered, making it child-friendly, while radiant room heaters are small and portable, and suitable for people with allergies.

2. Are oil-filled heaters better than electric ones?

Oil-based heaters consume less energy and produce constant and long-lasting warmth, but they may need a little time before they can warm up a room. Electric heaters, on the other hand, heat up instantly. When it comes to noise levels, oil-filled ones are quieter than electric heaters.
