I moved into this 1920 house and it has these Mr Heater vent free heaters in 3 rooms. Including the bedroom that 6 kids slept in.

Do they have low oxygen shut offs so they are safe? I have no idea how old those heaters are. The one in the living room must not have worked since the PO's put an old Franklin wood burner in the kitchen.

All I've got is this. I grew up in a real old single shotgun in the Lower 9th Ward and gas space heaters is all we had for warmth in the winter months.

There was one in every room except the kitchen and they were well used in the winter months with no issues, and this was long before any auto shut-offs were put into place or and carbon monoxide alarms were even invented.

I now have central air and heat for my upstairs living area, but have a modern gas space heater for the downstairs man cave and have had no issues with using it and that area is a hell of a lot more insulated and weather tight than that old shotgun I grew up in.

My grandparents' house had one in the kitchen. The ceramic infrared type. That was their only source of heat and it chugged in the winter. No issues in their home. It's now in my dad's shop.

I grew up with my mom kicking the gas oven on and leaving it open in the mornings to get the chill out of the air. Never an issue with that either.

Thanks for the replies and easing my mind a little bit.

Maybe they are safe and easy to use. I will get someone in to show me all about them.

Also highly recommend making sure you have a CO detector or CO / Smoke combo detector installed in the house.

1918 house here

I now have central air and gas furnace but still have the wall heaters in the bathrooms. Absolutely no safety shut-offs. When it get's really cold they're nice to have getting out of the shower. We've never had anyone have issues.

People have used them inside houses for over 100 years. One thing to consider is that older houses weren't sealed and insulated as well, so fresh air was constantly seeping in from outside.

They have but that does not mean they didn't have problems. I grew up with gas space heaters and personally loved having them. My mom was always very conscious of the hazards, though, and drilled safety into us. She personally knew at least 3 families that lost their homes and one of those who lost a loved one due to fires caused by space heaters. That was more frequent in days past and those were actually the floor type, not wall-mounted, gas space heaters.

From an efficiency and effectiveness point of view, they greatly outperform electric space heaters.

I randomly picked one of the units and looked at the manual and it does have a low oxygen cutoff. See if yo can locate your model and double check

Maybe it didn't work and maybe they just decided to go wood-burning. One of the things wood-burning stoves often provide is better heat exchange into the room due to the location being away from a wall, but that is dependent on the location of the wood-burning stove.
