Homemade Air Heater – Will This Work?

Help!!! [Don’t want to burn the house down.]

Q: Hi all very simply it’s copper tubes, small pc fans, and surrounding the copper tubes is several 15 to 20w quartz halogen (I think?) heater spotlight lamp bulbs. If this is placed in a wall to heat a small bathroom bringing cold air outside in, will it be able to do so? Thanks a bunch – any recommendations for efficiency or a similar design welcome. – A1d4n_18

A: Sounds pretty good to burn your house down. How is this cheaper than something UL approved?

You’ll also not be anywhere near the same efficiency as something off the shelf. Don’t do it.

This. Pick up a wall can at the local big box home improvement warehouse for $100-200. It’ll not be a fire hazard AND it recycles warm air from the room, not cold outside air.
