How to Buy the Best Crawl Space Heaters

There are different things to look out for when shopping for a crawl space heater. So whether you are going for convection or fan-forced heater, below are some crucial factors to consider:

  • Safety

“Safety first” is one of the foremost considerations when shopping for most home appliances, and the crawl space heater isn’t an exception. The space heater has been reported as a common cause of house fires, especially during winter. Thus, before purchasing a space heater for your crawl space, you need to double-check its safety status.

Several space heaters come with automatic shut-off features. In essence, the space heater automatically shuts off itself when it starts to overheat. This helps to reduce the possibility of a fire outbreak. Besides, a lot of these heaters come with safety-conscious exterior cases targeted at keeping them cool to touch all the time. Thus, be sure to look out for these features before you order that space heater for your crawl space.

Also, several space heater models have been tested in different laboratories for safety. Usually, these models bear letters such as UL, CUL, NTRL, etc., to show that they meet some safety standards. This serves as an additional form of assurance that the unit you are about to purchase has satisfied some safety requirements. Thus, it is best to get a model that has any of these safety certificates.

  • Heating Capacity/Size of Space

How big is your crawl space? Well, you need to know the size of your crawl space before choosing a space heater. Determining the size of the space that can be seamlessly covered by the heater is usually done by considering the wattage rating of the heater. As a rule of thumb, a room heater consumes 10 watts of power for each square foot. However, this isn’t applicable for all models as the heating technology and type of space also determine this.

The good part is that a lot of space heaters have express indications of the space size that can be adequately heated by them. So, you should be on the lookout for this to avoid getting a heater that cannot sufficiently heat your crawl space.

  • Energy Efficiency

The energy efficiency level of a space heater is one other factor you need to consider before purchasing a crawl space heater. You do not want to trigger an avoidable increase in your electricity bill because you made the wrong choice. Some models already have indications about their levels of energy efficiency. Also, space heaters with features such as low wattages, adjustable thermometers, energy-saving mode, etc., are known to minimize energy consumption. These are some of the features you need to pay attention to while choosing a space heater.

  • Low Maintenance Operation

Due to the nature of the crawl spaces, it is only logical to get a space heater that requires only a minimal level of maintenance. It is not beneficial to get a space heater that requires daily routine or maintenance checks for your crawl space. Thus, opt for space heaters that would only require occasional and straightforward maintenance actions. The Dr. Infrared heater reviewed in this article ranks high for this feature.

  • Durability

Flowing directly from the low-maintenance feature is the durability of the heater. There’s no point getting a space heater that needs to be changed quarterly or yearly when you can easily buy a durable one once and for all.

While durability sometimes depends on use, some models are generally known to be more durable than others. More often than not, heaters made with high-grade stainless steel tick the box for durability.
