In addition to home use, some reviewers have also recommended this heater as a good option for workspaces that are too cold.

Some users do complain about the heat settings, which do not correspond directly to actual temperatures, making the heater a bit hard to use for new owners.

Frequently Asked Questions:

What “Size” space heater do I need?

As a general rule-of-thumb, it is advised to have 10 watts of power for every square foot of space you’re trying to heat with a space heater.

For example, the 1500 watt space heater should provide a “primary heat” source for a 150 square foot room – that is (10′ x 15′).

What is the Difference Between Ceramic and Infrared Heaters?

  • Infrared heaters can produce more heat than typical ceramic element space heaters and do so by using a Quartz Tube or “short wave” radiant infrared heat.  Infrared heaters actually provide a better living and breathing environment than ceramic heaters, because they radiate heat to warm objects around them.
  • Ceramic heaters are generally less expensive than infrared heaters and typically use forced air to heat the space. Forced air heat can dry out your skin and other objects in the room quicker as a result.
  • Quartz “radiant’ Infrared heaters are also known for their very quiet to nearly silent heating. This is due to the fact that many Infrared heaters don’t require the use of a fan, which is generally the source of noise in space heaters. infrared space heaters are a great choice for the bedroom or an office.
  • Infrared heaters have no moving parts, and therefore require less maintenance is required for infrared heating units. With no motor parts, fans, or filters there is no cleaning or maintenance required.

Do Space Heaters “Save money”? 

The short answer is “Yes” space heaters do save money – for stand-alone rooms or smaller sized spaces.

The Long answer: If you’re heating one or two small rooms, a thermostat-controlled space heater will be more cost-effective. If however, you’re attempting to heat an entire house or apartment – gas energy furnaces are far more efficient vs. multiple Electric space heaters.

Energy Cost Formula for Space Heaters:

Cost Scenario to run a Space heater:  Assuming you use the heater on the lowest setting, and it uses 900 Watts. If you run the heater for 24 hours a day x 7 days a week for a month, it would cost approximately $120 (assuming electrical cost is $0.18/kWh).

However, If you used the same setting for 30 min a day, it would cost $2.50/month – (again, at $0.18 kWh/Hr.)

It is important to mention, space heaters on not considered a “high efficiency” source of heat.  This is why the appliance rating site “Energy Star” – does not rate the energy use of space heaters.

Space heaters do serve a valuable function in homes, offices, or RV’s, etc. however, and will do a fantastic job of taking the “chill” out of your space.
