Product Description
Amazon.com Product Description
For convenience and flexibility in an outdoor-only heater, it's hard to beat the Mr. Heater MH24T 8,000-28,000 Btu double heater. This unit gives you the option of using one or two burners and mounts directly on one- to 20-pound cylinders. It uses infra-red heat, which means that it warms the objects in front of it, not the surrounding air. This gives you more heat per Btu, which means that using both burners at the highest of the three settings will keep you warm even in miserably cold situations. The heater shuts off automatically with loss of flame. Do not use in unventilated areas. One-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.
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.

* This heater puts out a lot of heat. Do not place any item that can catch on fire within four(4) feet of the front of this heater. Do not place any item within six(6) feet of front of heater that you do not want to get very, very hot. With both burners on, even on low, one can feel the heat emanating from it 10 feet away.
* Items to the side and rear over a foot away do not receive direct heat and do not get hot. If one builds a stand/brace to hold it a foot away from any rear or side surface, this could be easily wall mounted rather than mounted on a tank. In a workshop, one could use a 12' extension hose and place the tank out of the way.
* This model requires lighting it with a flame. You will need to purchase a butane lighter with long nozzle or fireplace type(extra long) matches.
* You can light one or two burners but once lit you cannot shut-off just one. If you lite two and it gets too hot, you have to turn off the heater and light one burner.
* The hose is very short and fittings are under considerable stress if used as suggested by attaching directly to (20#/30#) propane tank. A short extension hose is advised. This also protect the brass connection from too much wear.
* It is pretty quiet but does have a constant hiss and will ' sing hi & low ' loudly when it first starts.
* If you are going to need it for extended time, you should plan on having at least two 20# tanks, minimum. If the power is out due to a storm and not expected back on for weeks, you might want to buy a 40# or even larger tank. NB: A 40# tank will weigh > 70# when full - not light!
* If using this for indoor heating, do NOT use it in an unvented area. This heater will suck the oxygen out of a tightly closed space in a very short time. Do not use it in any area without venting it so that a fresh supply of air is always available. An old house like the one I am remodeling has plenty of air exchange but new homes do not. If it must be used inside, place near a window and open the window a little so that fresh air is supplied. CARBON MONOXIDE POISONING AND DEATH CAN RESULT IF YOU DO NOT DO THIS!
( A _vented_ fireplace is another good location to place the heater. )
Other than the inherent danger in burning anything, especially burning anything inside a home, the only problem with it is that it gets so hot that one cannot be near it ... or even walk in front of it with 3 or 4 feet.
The most obvious missing item is no thermostat control to regulate the output of the burners. Manual intervention is the only way to regulate temperature in the area.
I like the heater. However, it is an ugly eyesore and really has no permanent place inside any living space, IMHO.
For a situation where normal heating is not possible, it can and does heat a couple of rooms in a very drafty old house enough to be comfortable even when it is below freezing outside. Once the normal heating is restored this will make a great workshop/garage heater and also very nice for grilling outside in the winter without freezing the buns.
If the situation is not so dire and there is some heat available, the smaller 'Buddy' version, which I also have, does very good. However, it cannot handle unheated areas when freezing temperatures are present.
...
Although not perfect, it gets five stars because there is nothing better, it works as Mr. Heater promised and should be usable for quite a few years in the future.

I have the older version that is functionally identical to the current version (they replaced the L-bolt that holds the heater on the tank with a ribbed knob on the new version). I love it for taking the morning chill off the house in the morning. I keep it in the kitchen and fire it up first thing on a cold morning. After about 30 minutes the chill is off not only the kitchen but the adjacent master bedroom and living rooms.
Be cautious - like any unvented heater it can be dangerous if you try to heat an unvented space for any length of time.
It is economical to use and even more so if you are able to find a local propane tank refiller. If you are forced to exchange the tank, it can cost [$$$]. If you have the tank refilled it will only cost [$$$].
My heater was given to me, used, and I liked it so much I gave one to my sister to use when she didn't want to burn the fireplace. I am now going to buy a newer one for the house, and relegate the older on out to my workshop.
Reliable, efficient, made in the USA - whats not to like.

I bought one of these for keeping me warm in the garage while I'm working. My garage is too big to economically heat the entire space, so I opted for a directional heat, as I'm typically somewhat stationary at the bench. This does the trick quite well!
The unit is solidly built, and I've used it now for about 4 months without a problem.
A couple of improvements I think could be made:
1) The unit I have does not have an igniter on it, so you must light it via an external source (usually a match). I found I can easily light it via a small Benzomatic torch I own, but it would be nice to have an igniter on it. I'm not sure; perhaps a pricier model has this feature.
2) To connect the heater to the propane, you have to use a wrench. I would prefer if it were more like my BBQ grill, where you can tighten on the connection without tools.
Overall, I'm very happy with the purchase!
