Buying Guide for Small Office Heaters

Small space heaters are great for supplementing the warmth in your office, whether it’s during the cold months or you just need a little more warmth than the central heating system offers. Because space heaters are supplemental, they shouldn’t be a primary heating source for your office.

Here are what to consider when buying a small space heater:

  • Room size: If you’re looking for supplemental heating options, choose a unit that will provide warmth to the area you wish to heat. You can use different models for different rooms or simply buy one unit that covers your entire office, so long as it’s not too large of a space.
  • Energy efficiency: If you’re looking for an economical option, then choose a model that has energy-saving features such as automatic energy-saving modes and adjustable thermostats.
  • Safety: Look for a space heater with tip-over protection, overheating protection, and a cool exterior. Simply put, buying a safe space heater means the difference between life and death.
  • Design: If your office has limited space, you’ll want to choose a small space heater that looks like it wouldn’t take up valuable room space. For instance, if your office has limited floor space, look for a radiator-type heater with an adjustable pedestal.
