The Mr. Heater MH80CV 30,000-80,000 Btu portable propane convection heater is ideal for heating large indoor spaces of up to 1,900 square feet. The convection design draws cold air up from the floor through propane burners then distributes warm air out through the top, giving you 360-degree directional heat. The unit features a piezo push-button igniter, adjustable heat output control (from 30,000-80,000 Btu), and an "Insta-Lock" system for easy, tool-free assembly. For safety, the heater shuts off with loss of flame, and the sturdy base keeps it upright. The included 10-foot hose connects to 20-pound (minimum required) propane cylinder. CSA Certified.

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.

30-80K Portable Propane Convection Heater
I use the Mr. Heater 30-80K convection heater in my garage, which is roughly 625 SF with high 14 ft. ceilings, CMU block wall, un-insulated ceiling. During winter months of the teens outside, I can bring the inside temp of my garage up to 70 degrees within a short time. However, you may need to hang a box fan up near the ceiling or install a ceiling fan to circulate the heat back down, it puts out a strong trickle of heat in a 360 degree radius that is easy to regulate to keep from alternating between freezing and roasting.

The biggest plus for me with this unit it the lack of objectionable fumes as are produced by forced air kerosene heaters, the propane burns clean and is easy to purchase at my local filling station, no spills or lugging around 5 gallon containers of kerosene.

If massive amounts of heat are what you want, you should consider the forced air propane heater made by Mr. Heater. They put out massive quantities of heat in short order.

I get about 15 hours of use per 25 pound propane tank, the same type my BBQ runs on, by turning this unit on high and then shutting it down to low, alternating this cycle. You can use upwards of a 100 pound propane tank.

The unit is much smaller then I expected which is a plus, it is light and very well made and simple to use.

Lots of heat, and noise
This is a great heat generator, and sounds like a jet when running full blast. I love it, but when I use it on the covered patio of a party people think it is too loud. For working around it is good, but for a party situtation I wish I had found one of the short unbrella style heaters instead, the radiat the heat down better and are not loud.

Great heater for the money
I bought this as a supplement to a kerosene jet heater that I also use in my garage. I use the jet for quick heat up in the winter, but the down side is the fumes and lack of thermostat. This (Mr. Heater) heater is great if you are going to be working around it because it's cleaner burning and collapses for storage. It puts off a little bit of black ash if you burn it too low, but turn it up and it goes away.
