In this guide, we will look at the top 5 best diesel air heaters for home usage along with their pros and cons. So without further ado, let’s get started.

1. Mr. Heater MH75KTR Diesel Heater

Mr. Heater’s MH75KTR Kerosenheater is a high-quality heater for both residential and commercial use. This heater provides a strong, reliable, and long-lasting heat source that can be installed easily. However, the best part about it is its portability. This unit will provide you with continuous heat for up to 10 hours on a full tank.

The MH75KTR can be used indoors or outdoors and is equipped with thermostatic control that maintains an ideal operating temperature for your home.

It also allows you to essentially choose from the preset temperatures to match your needs. In case you need more heat, simply turn on the ignition and let it run until the desired temperature is reached.

The MH75KTR also includes a safety shut-off feature, so that if the unit overheats, the engine will automatically shut down.

This product comes with a 1-year warranty.

Factors to Consider When Buying a Diesel Heater

While it may look easy at first glance, choosing a diesel heater from a myriad of options can be difficult. We suggest you take the following aspects into account before deciding since heaters can be a hefty investment.

Size of the Room

This one may be obvious, but it goes a long way. When looking to purchase a diesel heater, first check what your usage is. A lot of the time, buyers will get a smaller heater and then realize it will not work as efficiently to heat their room.

If you are buying a diesel heater for your home, look at the ventilation system and the overall structure of the house. If the rooms are connected and have no sliders or doors in between, then you’ll need a much larger heater.


Just like the size of the room, it is also important to consider the temperature you need. For most cases, the temperature would be around 74 degrees Fahrenheit, but depending on your needs, you might want a heater designed for higher or lower temperatures.


Depending on the surroundings, the efficiency of the air heater can drastically vary. For instance, if you live at a high altitude, then you would need a much more efficient diesel air heater.

Similarly, if you live in lower regions and only need the heater for a small duration of the year, it would be better to go with a smaller and less expensive diesel air heater.


This one is a very obvious factor to take into account. You’ll notice that in the list above, the prices of the heaters vary dramatically. While it is true that you will likely get much better quality from an expensive heater, it is important to ask yourself if that’s necessary for you.

If your requirement is not that intensive, then we suggest you go with one of the cheaper options on the list.


For the best cozy experience, you don’t want to hear a large industrial noise running in the background.

This is not a grave issue for most heaters since they come with silencers that are designed to reduce their noise output. As you invest more in a heater, the noise reduction will also get better.


Deciding which diesel air heater to buy for your home can be difficult. There are different factors to account for including the quality and requirements. Plus, you also have to stay within your budget.

In this guide, we talked about some of the best diesel air heaters for homes. In summary, if you have an extremely large space to heat, then your best option would be the Pro-Temp PT-175T-KFA. However, that option is an industrial heater that’s appropriate for outdoor as well as indoor use.

If you don’t see yourself using your heater outdoors, it would be better to go with Mr. Heater’s MH75KTR diesel air heater.

That brings us to the end of this guide. Thank you for reading!
