Mr. Heater Big Buddy Quick Links


Mr. Heater Big Buddy MH18B, Portable Propane Heater

Mr. Heater MH18B, Portable Propane HeaterI’ve personally been using this heater for over a month now and it is the best portable propane heater I’ve seen. If you’re looking for an additional heat source or something to use for emergencies, I can’t recommend the Big Buddy enough.

The Mr. Heater Big Buddy was designed to take portable heat to a new level. Heating up to 400 sq ft., this propane heater puts out 18,000 BTU/HR. While offering a fan option, the radiant heat is what makes the Big Buddy awesome. The heater is equipped with a multi-position heat settings dial along with built-in low oxygen sensor. One of my favorite features is the tip over switch which ensures safe and reliable portable heat.


Mr. Heater Quick Disconnect Hose with Regulator for Big Buddy Heaters #F271803

Mr. Heater Hose with Regulator and Quick Disconnect for Big Buddy Heater #F271803This is the top of the line hose when it comes to connecting the Mr. Heater Big Buddy to a 2o pound propane tank.  It comes equipped with a regulator that reduces the pressure from your 20 pound tank to the lower pressure used in the Big Buddy heater.

Most hoses don’t have the regulator on them because each side of the Mr. Heater Big Buddy has a regulator built in. However, Since this hose utilizes the Quick Disconnect feature, it bypasses the two built in regulators.

While not necessary, The Quick Disconnect feature is a nice addition to the portability of this propane space heater. Note, there is only one Quick Disconnect located on the Mr. Heater Big Buddy. If you wish to connect two 20 pound propane tanks, you must use one of two options. 1: Use the standard connection on one side and the quick connect on the other. 2: Use the Mr. Heater 2-Tank Hook-Up Kit.
