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.

By Daniel J. Gilley on October 27, 2001
This heater is excellent and the perfect fit, for a certain set of requirements.
If you have electricity, use an electric heater. Don't bother with the hassel of propane. The cost isn't too different and the hassel factor is much higher than electricity.
I also don't recommend using the small canisters. That's an inconvinient way to go as well.
BUT. If you don't have power and need a cheap, safe heat source that you can run while you sleep, this is the best one made. Buy the 12' hose, place a 20lb propane tank outside, and run this heater all night with just a small crack in a window or door (just in case!). You will get > 100 hours of heat out of a tank of propane! Less than a buck to run it all night.
Highly recommended under the right circumstances.

Once and for all, here is the purpose of fuel filter for this heater. When you use this heater with a remote tank & rubber hose, it is imperative that you always shut the tank off first & let the heater run until it burns off all the fuel in the lines. YOU MUST DO THIS EVERY TIME. If you simply turn the heater knob to the off position, what you are doing is trapping 100 PSI of propane in the rubber hose. When high pressure propane just sits in your rubber hose, it literally causes the rubber to leetch a light oil that is part of the chemical composition of the rubber. If this oil forms and you have the filter on the heater, the filter will catch it and seperate it from the gas. If you do not have the filter, the oil will quickly work its way into the heater & destroy both the regulator & control valve. The heater can be repaired, but these two components will need to be replaced.

I use this heater when I camp in my trailer, and it works great especially when used in conjunction with a 20-lb. propane tank. If you do use a 20-lb. tank, however, I STRONGLY recommend that you use the fuel filter (around $10 and yes, this is mentioned in the manual) and also that you always close the propane tank shut-off before turning off the Portable Buddy so that all the gas is burned out. Why? I went through two units that started shutting themselves off about a year after purchase before I found out that oily residue starts building up within the heater when the previous two suggestions are not followed. Even when I tried cleaning it out (I did a complete disassembly), it was not successful unless the control unit and the regulator are replaced as well. I did find a lot of oily mess within contol unit area, but couldn't get it all so it's just as easy to replace the entire unit. What happens is that when you turn on the unit, it seems to work; but, as the oily residue works its way up to the flame part, it will start going out on its own - the time it takes to go out in my experience was around 1/2 hour. As far as the precautions go, the fuel filter was easy for me to find locally where propane items are sold (farm stores, large sporting goods stores); it is easy to install (it screws into the heater where a 1-lb. bottle would be located and then the hose to the tank screws right into the fuel filter - it should last a year). I pick up an extra one once the current one is being used. I'm getting in the habit of shutting off the gas first. I would give this heater 5 stars if they would have explained this malfunction better - I ended up talking with tech support before finding out what was actually wrong.

Also, even in very cold weather, I leave about 6" of window open to keep the condensation to a minimum.

This heater is perfect for tent camping in larger tents. It's not too big and pretty stable. We have a large cabin style tent that sleeps 6-8. On our last camping trip to our local Southern California mountains in January 02, the temp at night got down to the mid 30's. Mr. Heater kept us almost too warm, even on the low setting. Our kids ended up sleeping on top of their sleeping bags. The safety features and BTU range were the deciding factors in our purchase. The low oxygen sensor gave us peace of mind(I still purchased a battery operated Carbon Monoxide sensor for the tent for extra precaution)and the BTU range was good. I could not find any other indoor approved heater that warmed us so well. At first I purchased a infer-red heater that attached to a bulk talk. I found too many reasons why not to use it in the tent(No low O2 sensor, no heat shield, and no low setting). Don't chance it. Get an 8 to 12 foot extension hose and a bulk tank. The portable tanks won't last all night. I wouldn't recommend this heater for small tents(not enough space, not enough air volume, and the potential for Carbon Monoxide problems is too great).

Verified Purchase
Just to clarify what a previous reviewer stated, although both are common products of combustion, DO NOT confuse non-toxic carbon dioxide with deadly poisonous carbon monoxide.

True, normal combustion of propane, or any fuel, creates combustion byproducts that consist of carbon dioxide (CO2) and water vapor. The danger is, in enclosed spaces such as cottages, tents, recreational vehicles and campers, any of these devices (whether they run on propane, naphtha, kerosene...) can also quickly produce dangerous amounts of carbon monoxide when starved of oxygen.

That's why this heater features a low oxygen shutoff system that automatically shuts the heater off if the amount of oxygen in the air gets too low. Still, you should always provide adequate ventilation when using in enclosed spaces.
