Rated 5 out of 5 by from Great heater This is a super little heater - I use it in the living quarters of my horse trailer when I don't want to bother starting the big generator, and it heats the area up in no time. Very economical to run for superfast heat in small spaces. I would certainly recommend this heater

Questions & Answers

How long will the 1 pound cylinder last and does it fit inside the unit?

The bottle can last 4 hours.. on high ...give or take. With the variables I recommend to test on a timer to give a dialed in result to determine the number of bottles needed for your use. thanks, Rich Mr Heater

using this in a golf cart can you remove the shut off when bumped to remain on?

Asked by: Spike 61
Thank you for your inquiry. This heater cannot be used in a golf cart and the tip switch cannot be removed. We do however sell a specific golf cart heater that does not shut off when bumped.

I have the mr buddy heater,worked perfect last winter,then put back in the box until now, have it hooked to a 20lb propane tank which I just filled , held pilot knob down repeatedly for 1 to 3 minutes, igniter works but pilot will not lite, what’s wrong?

Asked by: Dale8709
HI Dale, Give the ceramic and pilot tube a blast with canned air. Relight. If that does not work. Dip qtips in alcohol into the tube and let sit for a minute. Look at the behavior of the pilot flame ... does it touch the wire end of the thermocouple? is it curled? is it yellow. continue cleaning until the flame is blue and straight and it will keep the burners on.
