Dear Source Network, Recently our infrared heater that we purchased this fall would not stay on for more than a few minutes. I called your company and spoke to a very knowledgeable gentleman. He was so helpful and within three days we had the correct part to replace and our heater has worked perfectly ever since. I can't tell you how happy I was to speak to a technician and not just get a recording when I called. I would recommend your heater to EVERY ONE! Thank you very much for your great product and excellent service Sincerely, R. Lister March 28, 2012
