It says it heats up to 700 square feet on your website but on the Mr. Heater website it says this model heats up to 1250 square feet. Can you confirm what the number is? Thank you

Asked by: Laguna Boss
It’s a 50,000 btu hater so I am sure it’s capable of heating a bigger space.  I have a 2 car garage and it heats up in no time and is very efficient.

I’m thinking either propane heater or heat pump for my garage. It’s 676 sq ft. What’s your opinion on this working for something that size? Live in Atlantic Canada. 

Asked by: TheMaritimer
This unit is ideal for heating areas up to 700 sq ft, so this would be ideal for your garage!

Thanks to all who answered. Last few things...I want this to leave it on during the winter...foresee any issues and what’s propane usage like?

Asked by: TheMaritimer
There should be no issue running the unit through the winter. These units will run approximately a half gallon of propane an hour.

I have a sunroom about 400 sq. feet. I had a cozy wall furnace, but it broke down this year. Could I use this heater instead?

Asked by: Peter
Hi there Peter, You would need the proper ventilation first and foremost. If that is possible, it will head up the space no problem, but the unit is very industrial looking and would be more suitable in a garage.
