An example of Mr. Heater’s product to be used indoors is the F2320000 MH9BX Buddy. You can check the price of the product on Amazon here.

The feature of this brand is that:

  • Have higher features than the typical Mr. Heater brands for outdoor. This is because it makes more to produce the heater in such a way that it is used suitable and safe for indoor use.
  • It is made in such a way that the heater can detect low oxygen levels and automatically turn off.

Can I Run Mr. Heater Through the Night?

Even though Mr. Heater has been built in such a way that it is suitable indoors, it is very risky to leave it running all through the night. The heater has an open flame source so it’s not recommended that you leave running all through the night.

Nevertheless, even though there is an automatic shut-off system if the heater falls or probably tips over, it is still not advisable to run it and go to bed.

Nothing will happen to you if you decide to run indoor Mr. Heater product through the night but to be very safe and conscious of any strange occurrence, it’s best to stay up if you make a decision to keep it running all through the night.

While using it, you need to have your room well ventilated to avoid carbon monoxide poisoning when in the room. This ventilation will help you ward off any putrid smell and keep you safe all through the night.

Will I Die if I Use Mr. Heater Indoors?

Mr Heater won’t create a brand that would be all about killing people who use them. You cannot die when you use Mr Heater specifically created for indoor use.

What can result in death is when you use a Mr. Heater meant for outdoors inside your house. The carbon monoxide is bound to kill you.

Why is that? The carbon is odorless so you’ll inhale it for a long time while not knowing what you are breathing in and then, the inevitable happens because of inhaled oxygen.


Someone would ask for the price of Mr Heater and I’ll say that though the value is quite bigger than the size, it is worth it especially because of the main reason for which it was created; to help you ward off cold. If you follow the instructions on the manual, then you can enjoy your Mr. Heater Buddy for a long while.
