1500 watt. Sun Heater.I purchased a sun heater 1 and a half seasons ago. I have been completely satisfied with the service after the sale. Any questions I asked the dealer were answered very professionally. It is difficult for me to say exactly how much propane cost I have actually saved but I know I had a 1/3 of a  500 tank left last spring where as other seasons it was near empty.
