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.
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.

Update a month after purchase... I can't keep this thing lit. If I use a full propane bottle it will usually light and stay lit, but anything less than a full bottle and if I do manage to light it, it may or may not stay lit. My workshop has only this and an electric heater and it's 20 degrees F out there right now... And my heater won't stay lit. It will light as lob as I hold down the button, but even after a full minute of holding it, when. I release the button it turns off. I've written Mr. Heater so we'll see if they can fix the problem. Oh, and I have two different propane bottles and the story is the same with both bottles so I don't think it's the bottles causing the problem (faulty valves or whatever). I'll update,you review when I get an answer from them. I really want to like this heater but at this point it's useless.
This Mr. Heater unit is a bit more industrial looking than those but it's low profile keeps it from grabbing your attention.
What you don't see in the picture (or in the manual or in the description) is that the supplied hose for connecting to the LP cylinder is a generous 12 feet long. The manual (which is overburdened with safety information) wants you to keep your LP tank at least 6 feet away so this gives you plenty of lee way.
Some people have noted problems starting the unit with the supplied piezoelectric starter but I had no issues there. It starts reliably for me every time. I have to admit that it does take a bit longer than I was comfortable with the first few times and there is a definite "woosh" that you get as the gas finally ignites but I never felt it was dangerous and the piezoelectric spark is visible so I *know* it's going to catch in fairly short order. It seems to take about 3 times longer than does my piezoelectrically started bar-b-que.
One note: The Mr. Heater website is not that great. You can't register your products there as of this writing. And their "contact them" form suffers from the same issue (cannot select mandatory State field), so you've got to use an actual stamp to register. A minor item unless you need support from them which I did not.
