Like money others, the Mr. Heater F270320 MH125KTR uses kerosene, a combustible liquid that used to be called a variety of names like paraffin, lamp oil, and coal oil. The kerosene is burned quickly in this style of heater and then propelled through a tube that resembles a cannon, sending heat through a large space in a short amount of time. This particular product is one of the best kerosene heaters on the market for a variety of reasons, but one of the most important is the sheer square footage this Mr. Heater is able to cover in a short amount of time.

Product Overview

Significant Features

Because of its size and significance, the Mr. Heater F270320 MH125KTR comes with a couple of additional features that help this heater stand out from the rest of the competition. Perhaps the most crucial is the presence of over-heat sensors that trigger an automatic shut off when the device starts to get too hot.

Besides its auto shut off, this heater also includes an adjustable thermostat and high output fan. The thermostat means users can determine just how hot they would like an area to become, while the high output fan ensures as much heat as possible is transferred to the room. Users do have some control over the power of this fan if they would like to work within a smaller area and not waste fuel heating empty space.

Finally, there are a couple of convenience features. One important one is an illuminated on and off switch that is easy to see in the dark. In addition, air pressure and fuel gauges inform users just how much pressure is produced and how much kerosene remains in the fuel tank. There are finally a couple of minor additions like an easy on and off gas cap, a cord wrap to store the plug when the heater isn’t in use, a steel drain plug, and an electric outlet. The full device is certified by CSA.

Although it’s not obvious, the Mr. Heater F270320 MH125KTR can be used indoors and outdoors.
