Mr. Buddy Heater
Mr Heater's Big Buddy MH18B Propane Heater
What a fantastic new addition to the Buddy Heater line! Their new integrated hot air blowing system takes
portable heating to new level. This is a great unit for either back up heat in your home when your power goes
out, for the shed, the cabin or porch. Believe it or not, this unit puts out 18,000 BTU's and heats up to 400
square feet! You can run it it up to 220 hours on a single 20 pound tank. The included blower fan runs
on 4 D Size batteries or you can purchase an optional A/C adaptor. The MH1B also allows you to choose from
several heat settings to keep the room at a temperature that you are comfortable with. The days of a having
to go through hot and cold spells are over when you put this unit into operation.
Another interesting feature of this unit is that you can use the small cylinders instead of a 20 pound
tank. You can expect to get about 50 minutes out of a single cylinder while operating in full heat
mode. You do have the a ability of using two cylinders at a time, which is something I'd suggest so that it
will lengthen the time you can go without having to change cylinders. There have been some concerns that when
running this unit under 40 degrees, it shuts down due to an icing issue. Another issue is that if you choose
to use a larger tank than a 20 lb. tank, you'll have to purchase a regulator.
Overall, this is an outstanding unit to use as a back up to your normal heat source!
Mr. Heater Little Buddy F215100 MH4B
The Mr. Heater Little Buddy MH4B is a great little indoor propane heater. It delivers 3800-BTU, which is
enough to heat a room of 100 sq. ft. quite nicely. It'll run up to 5.5 hours on a 1 pound propane
cylinder. You can easily direct the heat where you want it with its 45 degree heating angle.
This is a great unit for anyplace you need instant heat. A cabin, a tent, in a camper, or as emergency
heat when your electricity goes out at home. The Little Buddy F215100 has a safety feature built in that when
it senses the slightest of movement, it shuts down. This is great in terms of safety, but it can be a bit of
a hassle if you are camping with it, or if you are using it in your golf cart on those early morning rounds.
A really nice safety feature is that it'll shut down if the oxygen level in a room you are using it in gets too
low. And, if the pilot light goes out, the unit will shut down completely. Measures 12"x10.5" by
A great buy if you have the need for an emergency heat source, or if you have a small area to heat.
Mr. Heater MRHF273400 Buddy Propane Heater
This Mr. Heater Buddy Propane heater is a perfect unit for those looking for an emergency backup heat
source. It'll give you instant indoor heat for up to 200 sq. ft at 4,000 BTU. Checking in a right about
8 pounds, just about anyone can lift it and move to where you need the heat the most.
The heater comes with a set up for a one pound propane cylinder that you can purchase locally. However, if
you intend on using this for an extended period of time, do yourself a favor and get the optional hose and use a
locally purchased 20 pound tank. It'll cost you less than a buck to run it all night with 20 lb.
In addition, purchasing the fuel filter is critical if you are going to use the 20lb tank. Why? If
you simply turn the heater knob to the off position, propane will be trapped in the rubber hose. Believe it
or not, when you've got high pressure (100psi) sitting in the rubber hose which causes the rubber to produce an
oil. Without the filter in place, it will get into the heat and render the heater's control valve and
regulator useless. Before being able to use it again, you'll have to replace both parts. Not only is
this a hassle, it could get very expensive. Of course, this situation can be avoided by shutting the tank off
first and letting the heater burn off the fuel in the line. Better to get the filter in case someone forgets
to turn the tank off first.
If you don't have a 20lb propane tank and don't want to buy one along with a filter, I don't recommend using
this unit as a supplemental heat source. It simply won't be cost effective to use this instead of electric
It's safe enough to run unattended as it's got an automatic low oxygen shut off system. You can mount this
on a wall or use it free standing.
