New Propane Heater

I'm still experimenting with different space heaters to heat my tent in Autumn. The wood stove is just too hot to fire up until December, so I need a space heater to get me through October and November.

My first two Winters, I used a kerosene space heater. Kerosene heat is very economical and puts out about 22K BTUs, which is more than enough for my needs. But while kerosene heat has some nice advantages, I just didn't like the mess and the fumes, so last year I switched to propane. I chose a Mr. Heater MH15T tank-top heater, which puts out about 15K BTUs. The tank-top heater was also very economical, provided plenty of heat, was very convenient, and gave off no fumes. But the tank-top heater was a bit difficult to connect to the tank, and I just didn't like the design, from a safety standpoint. It had an automatic shut-off in case it tipped over, but I still didn't like the higher center of gravity on the tank, and the idea that the heater was physically connected to the tank. Also, the wiring from the thermocouple to the shut-off valve was just sort of hanging off to the side where it could be easily damaged. In fact, the thermocouple failed last Spring, but whether that was due to the wiring or to something else I don't know.

A few weeks ago, I went shopping for a new propane heater to replace the old tank-top that broke last Spring. I had been pretty pleased with the tank-top heater, and fully intended to just buy another one, until I saw the Mr. Heater MH9BX Portable Buddy propane heater.

Mr. Heater MH9BX Portable Buddy

The Portable Buddy had a lot of features that I really liked. It was a separate unit that attached to the propane tank with an adaptor hose, which meant that I could keep the tank outside of the tent if I wanted. It also had an electric ignitor, which wasn't available on the tank-top heater. It had an automatic shut-off in case of tip, like the tank-top model, but it also had a shut-off in case of low oxygen. And it was much easier to move around than the tank-top model. The Portable Buddy also had a more refined radiant panel, which provided a much quieter burn.

On the down-side, the Portable Buddy is nearly twice the price of the tank-top model, and it only offers 9K BTUs. That's only enough heat to raise the temperature in my tent by 20 degrees or so (compared to 30 degrees with the 15K BTU tank-top model). With only a 20 degree increase, the 9K BTUs will only get me into the low-60s on those cold November mornings in Virginia.

After scratching my head a bit, I decided to go ahead and try the Portable Buddy. I also purchased a 5' adaptor hose and decided to just leave the tank inside the tent for now (probably a mistake!) I've only used the heater a few times so far, but I like it a lot.The heater is nearly silent when it burns, and has a beautify orange glow that lights up my dark tent in the early morning. As the days get colder, I'll probably have to supplement the heater by burning my propane cook stove, too, which I occasionally do anyway. But the lower BTUs is more than compensated for by the improved safety over the tank-top model, which is a big advantage for me.
