Best Diesel Space Heaters 2023

December 18, 2022 by Editorial Team

The first step when shopping for a space heater is to determine whether you need a warm-air heater or a radiant heater. Warm-air heaters have a heating element that radiates heat in all directions, so they’re a good option when you’re sitting near the heater and need a wider coverage area. They’re often less expensive than radiant heaters as well. On the other hand, radiant heaters emit heat directly from the emitters, so they’re a good option when you’re sitting near the heater, but you also want some coverage on the back half of your body. Radiant heaters are also more energy-efficient than warm-air heaters.

So now that we’ve established that you need a space heater, we’ll help you find the best one for you.

Best Diesel Space Heaters Buying Guide

Before choosing the best diesel space heater you should consider following options:

1. Fuel source: You can choose from either a liquid propane (LPG) or a kerosene-based model.

Liquid propane units work by burning propane gas, which produces heat. They are cleaner, more efficient and easier to maintain than kerosene models.

Kerosene models are cheaper to run and produce more heat, although kerosene fumes are harmful and the smell can be unpleasant.

2. Space coverage: Decide how much heat you need. If you need to heat a big room, you need to buy a big heater.

The BTU rating will tell you how much heat the unit produces. The higher the BTU rating, the more heat the unit produces.

3. Capacity: The size of the heater will determine how much heat it can hold. If you need to heat a large room or a large house, then buy a large heater.

The unit should have a sufficient tank size to allow it to run for at least 8 hours.

4. Safety features: Look for safety features that include an overheat protection switch, a flame failure switch, tip-over switch, low-tank alarm, and a guard around the heater that prevents accidental contact with the hot heater.
