Mr. Heater MH125LP Salamander 125,000-BTU Portable Propane Radiant Heater Review

Average Reviews:

(More customer reviews)This unit looks extrememly well made, like other Mr. Heater products. But unlike their tiny portable units there is NO WAY to turn down the heat. 125000 BTUs is a LOT of heat, enough for nearly 3000 square feet. But it consumes nearly 5.5 gallons of propane per hour to do so. That would be OK for really cold conditions. But it is all or nothing. There is no thermostat or , as previously stated, way to turn down to a lower heat setting. I found a similar unit at Grainger that has three heat settings, (50/95/125,000 BtuH Output) and is priced the same, so I am sending this one back.

Five Tips for Buying a HeaterChoosing 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.

Mr. Heater MH25NG 25,000-BTU Natural-Gas Radiant Heater Review

Average Reviews:

(More customer reviews)This is a really nice unit if it fits your purpose. I must stress however, that is if it fits your purpose. As I now realize, 25,000 BTU/hr is not an enormous amount of heat. This unit really is designed for use in a closed in space w/ minimal air curculation. The heating method is to raise the temperature of all objects in the radiant field so that the space stays warm. A breeze or draft will reduce it's ability to maintain the heat. The unit comes with a thermostat for mounting on a wall and setting a desired heat. I've eliminated the thermostat and just hard wired the unit. If it's cold enough to have it on, then I want it on. Mr. Heater advertises using the term "millivolt" ignition or something to this manner. This is misleading. This is not a electronic ignition unit!!! This means the unit has a pilot light. The pilot light heats a thermocouple which provides the "millivolt" current they refer to. The thermostat either "opens" or "closes" the circuit, depending on the temperature and thermostat setting. The "closed" loop opens a solenoid valve in the pressure regulator which releases the gas to the burner.
My unit is installed on a large covered patio outside approximately 8' above a sitting area. Sitting below the heater in a 8' diameter circle is nice and toasty, even with a slight breeze. Sitting across the table at 12' you can feel a slight warming effect with no breeze. More than 12' away....no impact. This is not a highly effective heater if used in an open space. As advertised....this is a garage heater. To get the heat I need I am adding a second heater across the patio from the first.
Clearances around the unit are important. I have 2' clear above my unit, and the lumber above the unit gets warmer than I would like. After 2 hours of use I can touch the wood with my bare hand without having to remove it, but it is quite warm. I'm thinking about 120 to 130F. I have some harditrim up there too and it is even warmer. Not too sure how long the paint will last.
Installation is a breeze. Includes a video if you need it, but there is essentially nothing to it.
Good buy....if it's what you need. If you are thinking of installing it outside......you may want to consider getting more BTU's.

Mr. Heater MH42T 42,000-BTU Propane Tank-Top Radiant Heater Review

Average Reviews:

(More customer reviews)The triple burner Mr. Heater works wonderfully! Now this is what you call a radiant heater! Prior to purchasing Mr. Heater I was using a Bernzomatic patio heater (that cost significantly more) that didn't heat very well - I had to practically hug the Bernzomatic to feel heat. The triple burner Mr. Heater keeps me toasty warm! I love the red glow it gives off too! I installed Mr. Heater on a 40 lb. propane tank - this is just the right height to keep me warm while on my deck swing.
Mr. Heater isn't a particularly stylish unit - however, it sure does heat well!
I have a few minor criticisms; overall I'm very happy -
During my first week using Mr. Heater the burners kept shutting off - they would not stay lit for very long. I adjusted the thermocouples to position them closer to the burner and I haven't had a problem since.
Mr. Heater doesn't work very well in wind - it works fine in a breeze or a little bit of wind. I tried to use it on my deck in a storm with fairly gusty winds - not a good idea. The wind tended to cause the burner to ignite the chamber that carries the gas to the burner. If this happens - you'll know it.
It'd be really nice to have an electric ignition! The two burner model has this; however I really wanted a maximum amount of heat - I wanted the three burners.
It'd be really nice if the propane tank mounting hardware was adjustable for height. If I mounted Mr. Heater on a 20 lb. propane tank it'd simply be too short to set next my patio table or swing. If you could adjust the height a couple of feet that'd be nice - you can probably jerry rig something.
Overall, it heats great - an excellent value too, in relation to the cost of patio heaters (which is what I use this for).
******* 2//2010 Update *******
While it's been a great product the last couple years, another issue has become evident. Mr. Heater is not rust resistant! It's rusted to the point that I can't use it anymore. I kept it in an enclosed screened in porch so it was never exposed directly to rain. However, rain that was blown in and the summer humidity has had a big impact. I've replaced Mr. Heater with another manufacture's version that doesn't rust.

The Mr. Heater MH42T 8,000-42,000 Btu triple heater is a step up from the two-burner model, giving you the flexibility of using one, two, or three burners. The unit mounts directly to 20- to 100-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 all three burners at the highest of the three settings will keep you warm even in miserably cold situations. Each element shuts off automatically with loss of flame. Do not use in unventilated areas. One-year limited warranty.--Josh Dettweiler

Mr. Heater 80,000 BTU Propane Convection Heater #MH80CV Review

Average Reviews:

(More customer reviews)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.
