MHUniversity HERO Cordless Heater

The HERO is the First Cordless Forced Air Heater in the world featuring Quiet Burner Technology. This propane powered forced air heater no longer has to be tethered in one area. Cut the cord for a full 8 hours on a single 5 hour charge for the 35,000 BTU or a full 4 hours with the 60,000 BTU model. Or better yet, use an additional battery for the MH60CLP for a full 8 hours as well (additional battery sold separately). Powered by propane and a 12v lead acid battery, this is the future of jobsite heat. Equipped with Patented Quiet Burner Technology, this heater burns with 50% less noise, making the jobsite safer and enabling you to work with a little more peace and quiet.

HERO Cordless Forced Air Propane Heater FAQs

What does the heating area square feet mean?

Square footage is the length of an area times the width of an area. Knowing the square footage of an area allows you to estimate the amount of BTUs necessary to heat the area most effectively. A generally accepted formula is: Square Footage x 40 = required BTUs. This is just a starting point. Ceiling height, building layout, and level of insulation will also factor into your BTU needs.

The motor starts on my heater but no heat comes out?

Check to see that your propane supply tank is turned on. Listen for the sound of the spark igniter, it should make a fast ticking sound (Piezo igniter for the 35CLP so only one spark), if it doesn't replace igniter.
