Though it is the smallest in the Mr. Heater's line of forced-air kerosene heaters, the MH50K is still a powerful unit; at 50,000 Btu it provides economical, efficient, and clean-burning heat for up to 1,200 square feet. The built-in 4-gallon tank means there's no hoses or cylinders to fuss with, and it gives you up to 11 hours run time on the lowest setting. All products in this line include safety shut-off with loss of flame or power supply; all are CSA certified and come with a 1-year limited warranty.--Josh Dettweiler

Five Tips for Buying a Heater
Choosing a space heater is a matter of sifting through a bewildering array of types, power ratings, and fuel sources. Let's break it down a little to make the process easier.

What are the different types of space heaters?

• Radiant heaters emit infrared radiation that directly warms the objects in front of the heaters (rather than the surrounding air). If you only need heat by a desk or in a small section of a room, a radiant heater is quiet and will use very little power.
• Forced-air heaters use a fan to blow air that has been warmed by metal or ceramic heating elements. A forced-air heater is appropriate for quickly heating up a small- to medium-sized room, but can be noisy.
• Convection heaters draw cold air from the floor; the air is warmed by heating coils and emitted from the top of the heater. A convection heater is appropriate for quickly heating up a small- to medium-sized room, but also can be noisy.
• Radiators work by heating oil enclosed in a reservoir, gradually heating the surrounding air. If heating speed isn't an issue, you might want to opt for a radiator. These are extremely quiet and effective--perfect for bedrooms.

Should I buy an electric or a combustion model?
If you want a heater that will be available in emergencies, or that can heat areas larger than a single room, choose a "combustion" model--one that is powered by a gas or fuel like propane, kerosene, natural gas, or diesel. Which fuel type you choose depends largely on convenience and local availability. For example, diesel would be appropriate for a heater you take with you on long car trips.

How powerful a heater do I need?
Heaters are rated by BTU, which stands for British Thermal Unit (the amount of heat needed to heat one pound of water by 1 degree F). To find out how many BTU you need:

• Calculate the volume of the space to be heated by multiplying square footage by height.
• Multiply that number by 4 if your insulation is poor, 3 if it's average, or 2 if it's good.

The resulting number is a ballpark figure for how many BTU you'll need.

Do space heaters cost a lot to operate?
As a general rule, electric space heaters are more expensive to use than combustion models. To ensure energy efficiency, a thermostat is a must-have feature for any heater. For radiant heaters, models with a 360 degree heating surface can heat larger spaces. If you need a forced-air heater, models with ceramic elements tend to be more efficient.

Are space heaters a fire hazard?
Space heaters are implicated in about 25,000 residential fires every year. To ensure proper safety, always follow the manufacturer's usage instructions and fill out the warranty card to receive informational updates from the manufacturer. Also, look for extra safety features such as an automatic shutoff switch that can shut down the unit if, for example, it gets upended. In addition, choose a model where the heating element is adequately enclosed within the unit.

I am a home mechanic, use this heater for working on cars during winter time. This smaller heater can heat up 3 car garage in about 10 minutes. It is not as loud as 75K BTU model. so I can work on car during nights. My only complain is that the unit does not come with thermostat.

This review is from: Mr. Heater 50,000 BTU Kerosene Forced-Air Heater #MH50K (Kitchen)

Got this last winter for a 1200 sq ft garage. First one delivered leaked but Amazon.com immediately shipped a new one and took the first one back...best customer service I've ever had! Raises the temperature of my garage 10 degrees in ten minutes. Only regret I have is not spending the extra $$$ for a little more powerful one for really cold days, and one with a thermostat to turn up and down rather than plug and unplug the unit. So far so good.

This review is from: Mr. Heater 50,000 BTU Kerosene Forced-Air Heater #MH50K (Kitchen)

I've only run this heater to test it but it puts out a helluva lot of heat very fast with no kerosene fumes smell. The price I got from my vendor was fantastic, everyone else has it listed much higher. Later I ordered the remote cord thermostat but haven't gotten it yet. It should prove to be a good emergency heat source as well as general purpose cold weather heater for working outside. It should work well to thaw frozen pipes also.
