Everything You Need to Know About Dewalt Space Heaters

The right space heater can be a major asset to your home. Space heaters enable you to make spaces of all sizes more comfortable, whether you’re trying to avoid running a whole-home system or making accommodations for an inefficient system. Dewalt space heaters offer the versatility, dependability, and efficiency you need in a space heater.

In this guide, we’ll give you an in-depth rundown of the different types of Dewalt space heater and their optimal applications to help you make your choice.

The Best Dewalt Propane Space Heaters

Propane space heaters don’t use electricity as the main power source – they use liquid propane (LP) fuel instead. These heaters are incredibly portable because they aren’t limited by the constraints of power cords. They also have the highest heat output of the various types of space heaters. Here are our top picks for Dewalt propane space heaters:

Dewalt DXH70CFAV Cordless Forced Air Propane Heater

This propane heater features a durable stainless steel industrial housing with an electrostatic powder-coat finish. As a cordless model, it requires one 20v battery and it offers a variable rate valve for optimal heating.

Dewalt DXH170FAVT 170,000 BTU Propane Heater

A more powerful version of the previous model, this forced air propane heater delivers up to 170,000 BTUs of heat per hour. It features Quiet Burner Technology and a high-temperature limit switch for safety.

Dewalt DXH2000TS Propane Space Heater

This propane-powered heater delivers up to 68,242 BTUs per hour on high power or 44,357 BTUs on low power. It offers fan-only operation as well and operates with no open flame for maximum safety in the workplace.


While propane space heaters are powerful and portable, there is some risk involved when burning fuel. Some propane space heaters also emit carbon dioxide, so they are best for use outdoors or in well-ventilated rooms.

The Best Dewalt Electric Space Heaters

Dewalt electric space heaters are typically small and portable, though they’re limited to use in spaces with access to an electrical outlet. These heaters utilize various heating methods to warm small spaces. Here are our top picks for Dewalt electric space heaters:

Dewalt DXH330 Forced Air Electric Heater

This 3.3kW space heater features a proprietary dual coil support system and a fan to disperse heat. It offers thermostatically controlled two-stage operation. It is also compact in size, measuring just 13.62×15.75×17.12 inches.

Dewalt F340645 Forced Air Electric Heater

A more powerful version of the model above, these Dewalt space heaters are ETL certified and equipped with an integrated dual coil support system. They are thermal protected and can be run at two power levels, 10kW (50amp) or 7kW (30amp). It is also equipped with a 25°F – 95°F thermostat.

Dewalt DXH12B Portable Heater

Though technically not an electric space heater because it doesn’t plug into the wall, this Dewalt cordless electric space heater runs on rechargeable Dewalt batteries. It utilizes a high velocity fan to disperse convective heat for up to seven hours.

Generally speaking, electric space heaters are a little safer than fuel-burning heaters, but they come with the same risks with improper operation. Never leave an electric space heater unattended and place it on a stable surface away from flammable objects.

The Best Dewalt Kerosene Space Heaters

Another highly portable space heater, kerosene space heaters are also known as paraffin heaters. These Dewalt space heaters are fueled by kerosene and they come in a variety of forms. Some kerosene heaters use electricity to power a fan to force out heated air while others simply utilize a wick to draw kerosene from the tank which is then burned through convection or radiant heating.

Here are our top picks for Dewalt kerosene space heaters:

Dewalt DXH50K Kerosene Heater

Compact and portable, this 50K BTU kerosene heater utilizes forced kerosene-fueled heat. It is ideal for at-home use, heating spaces up to 1,200 square feet. It offers recessed controls and can be used with a thermostat (sold separately).

Dewalt DXH215HD Forced Air Kerosene Heater

One of the most powerful kerosene-fueled Dewalt space heaters, this model delivers up to 215,000 BTUs per hour. It heats up to 6,500 square feet of space and offers a run time of nine hours.

Dewalt DXH135KT Forced Air Kerosene Heater

In between the two models above, this forced air kerosene heater has an output of 135,000 BTUs which can heat spaces up to 3,500 square feet. Because it is so large, it comes on a wheeled cart with foam-filled flat-free tires.

Like any heater that burns fuel, kerosene heaters need to be used with caution. They are best used outdoors or in well-ventilated spaces and should be kept away from flammable objects.

What to Look for in a Space Heater

With so many options on the market, it can be difficult to make a choice. While we highly recommend Dewalt space heaters, there are plenty of others to consider. Here we’ve covered some of the basics in what you should look for when shopping for a space heater, regardless of brand.

Here are some things to consider when shopping for a space heater:

Heating Type

Space heaters typically utilize one of three heating technologies: radiant, convection, or fan-forced. Convection heaters are great for whole-room heating while radiant heaters offer spot-heating for small spaces. Fan-forced space heaters incorporate an internal fan that blows air across a heating element. Another option, infrared space heaters, use a quartz heating element and they are very energy-efficient.


Different space heaters are designed to heat rooms of different sizes. Generally speaking, a heater uses about 10 watts of power to heat one square foot of space. This means a 1,500-watt space heater can heat a 150-square-foot room.


If you’re going to be running a space heater for any significant length of time, energy efficiency is important. Look for helpful features like energy-saving modes, automatic shut-offs, low wattage, and programmable timers.


Make sure the space heater you choose has safety features like cool-to-the-touch surfaces and automatic shut-offs.

No matter which space heater you choose, from convection heaters to infrared space heaters, it’s essential to operate it properly. We recommend reading the instruction manual to determine how to set up the space heater, where to place it, and how to run it. Never leave a space heater running in a room unattended and make sure it is placed well away from furniture, drapery, and other items that could be a fire risk.
