Yesterday our heater arrived.  It is installed and I am impressed with the efficiency and heat output.  Here in Wisconsin the temperature this morning was 44 outside, and 48 inside my unheated garage woodworking shop.  I turned on the unit, and within minutes I was comfortably having my morning coffee and planning my shop activities for the day.  I would highly recommend the SunRayz to any woodworking hobbyist or professional as a clean, safe, efficient source of heat.

Thank you for your excellent customer service, quick response, and helpfulness.
