Really Fast Shipping to my house
The price was the lowest that I could find online and the heater came a couple of days later. I was very impressed with the fact they had the product in stock and that shipping was so quick. Many other places had the heater backordered and charged for shipping too. I just had it installed last week and it worked flawlessly.
Great Job Supply House.

Perfect for a garage workshop
Installed this heater for a client to use his 2 car garage as a part-time woodworking shop. Separated combustion mandatory for sawdust, paint thinner fumes, etc. Installed in Chicago area where the winters are cold.

Product Q&A
1 Question1 Question
Q: Ugh.. new home build. we have a 1000 square foot 3 care garage. High R value insulated garage doors, 2 x 6 insulated walls and dry walled. Will this size do ok? Seems on the small side. Ceiling mounted and professionally installed and vented. Just want to keep the garage around 55 or so. Not using as a workshop. Thank you.

Verified Reply- SupplyHouse StaffHi Roony. To be sure, we would need the height of the space. Assuming the space is 10 feet high and the area is about 10,000 cubic feet, your BTU/h requirement would be about 50,000, so this unit would be on the smaller side like you said.
