(warm but unsafe and imported: temporary use only)
OFF TOPIC. but these can be dangerous
put them on brick 2' on every side and keep flammables 4' back
but THAT NEWS may be fake news: these "new" ones are made cheap as possible all in china - they have "small fasteners". small fasteners and heat done mix: they pop off. a heater which is "unraveling itself" is a fire waiting to happen and big business isn't going to give you those warnings (it would reduce their import markup sales). there's a reason old stoves are not thin metal but iron with heavy fasteners: it's because small fasteners and rust holes in thin metal caused fires.
big media is never going to tell you if homes caught on fire due to failures in these imports. you can't sue a china company either: they are in another country why would you think you could sue them? which caught fire first - the oil heater or the surrounding material?
A SAFE WELL MADE STOVE OR HEATER HAS TWO LONG PIPES, one to bring in fresh air for the flame (so you dont' have a window open letting the warm air out), the other so exhaust gasses done choke the people indoors.
UNFORTUNATELY, MOST DO NOT CONSIDER IT NECESSARY TO HAVE TWO SUCH PIPES WHEN HOMES ARE BUILT - infact many home hvac have no oxygen intake pipe and letting in fresh air at times is necessary for safety if your house is "well sealed"
What You Must Know About Kerosene Heater Repair - HomeQuicks - they're a disposable product from china - the idea you can fix it is wrong - if you merelate take one apart and re-asseble it you may have made it unsafe - if you don't have to break it to achieve doing that
