Mr. HeaterMH12HB Hunting Buddy Portable Space Heater, Camouflage

which hoses can you use to connect 20 lb. tank?

When I put the heater setting on low, it sputters and makes a lot of noise, is this normal, but works fine on high. Thanks

Can i use it in a car while i sleep in there overnight?

Would this be good for on a house during a power outage?
