Mr. Heater 30,000 BTU Natural Gas Blue Flame Heater F255539
Product Review (submitted on January 11, 2014):
Heater arrived within 3 days of purchase. Only problem was trying to find a gas plumber willing to hook it up took 2 weeks. It seems many are reluctant to install/connect this type of heater. Call around before you order one. Once I got it connected it fired right up and works great. I was going to go with a vented model but the price was 15 times what this sold for and for a non-living space (basement) not worth the extra money. I would buy from these guys again no problem.
