Q: Does the kerosene htr mfg #F274870 allow room heat to get to and maintain a temperature above 120 Fahrenheit?
5 months ago1 Answer

It's unlikely that the heater would keep the heat above that temperature, since burning continously in a room that's small enough for it to heat to that level would likely trigger the heater's oxygen depletion sensor, shutting it down for safety reasons.

Great Emergency Backup
16 years ago
If you live in the country you know extended power outages can be a way of life. Living in a cheap mobile home without the best installation requires something to keep me from becoming a redneck popsicle and this is it. Can take the small disposable propane tanks or the large tank with the optional (not included) hose. Don't forget to purchase the batteries for the fan.
Read the instructions completely to prevent making the common mistakes.

Unreliable
9 years ago
I purchased this heater, fuel filter and 12’ hose adapter for large propane tank Dec. 2016. It worked as advertised through Jan 2017 after burning 2 five gallon tanks of propane. Starting in Feb. it would quit working while set on low and became difficult to light. Now it will not work at all. I’ve followed the manual troubleshooting procedures, tried the small bottle of fuel bypassing the filter, hose and large tank. Still inoperative!!!!
