Mr. Heater warranty for jobsite heaters

18/100 Warranty ScoreRanked 2 of 3 brands
The short version

Mr. Heater doesn't cover everything, but keeps unit heaters and whole product (parts and replacement) covered to 3 years. That full coverage is the same as most of the 3 brands we compared, which typically cover nothing in full. You don't need to register to get this coverage.

From Mr. Heater's published warranty, checked October 2026.

The fine print, decoded

What it leaves out

  • Normal wear and tear
Good to know before you buy
  • Keep your receipt; you will need to send proof of purchase and the serial number.
  • Using a Buddy heater to cook or warm food, or with third-party accessories, voids the warranty.
  • Mr. Heater sends a replacement or parts; it does not pay for repair service.
