This fall I needed to replace my EMPIRE unit. Not sure if you are close to the big pond or not, but I priced one out at a HVAC place in Isle. They were listed as a DEALER, but didnt stock them. could drum up the name if you needed it.. ended up being about $500-600 more than the Williams heater from Menards, after (11%) rebate and free shipping. I went with the Williams. The Williams was really nice this year, I was impressed. Got blower add on and it put out crazy heat, comes with thermostat. Dimensions were a little smaller than the comparable Empire unit also. Simple operation and seemed like a quality product.
