I bought a couple of outdoor propane heaters for my bars patio from saferwholesale.com. These heaters work a lot better than I thought they would. The patio is only 150sq ft and two of these heaters works perfectly. Our smokers love the fact that we're keeping the patio warm for them in the winter, and a lot of them have been asking us to set the furniture up so they can just hang out back there. I have a feeling once smokers realize they have a place to smoke, and keep warm, in the winter that we may get more customers. Good product and company.
