Awhile ago I posted about heating my shop. I bought a Dimplex 220 volt heater from Amazon. I have had very little time to spend there. But the time I have spent there gave me the opportunity to use the heater like today. I turned the heater on. It was 42 degrees in the shop. I ran a few errands and coming home the shop was 60 degrees but the red light came on. I lowered the thermostat until the red light went off. Then it started recycling as it should. However, the heater never raised the temperature more than 62. My shop 112 sqf and well insulated. I had installed the heater a number of weeks ago and it did the same as above. I thought the heater was defective and returned it and reordered the same heater. This second heater is not doing the job well. In a shop the size of mine it should sweat me out. I have a milk house heater that is 110 volts but I can't have something on the floor to stumble over. I may just purchase a larger heater. Sixty degrees is comfortable enough with a heavy shirt but I like working in a T-shirt. Some of you had asked how it worked out so this is my review. The pro's are light weight, fairly quiet and inexpensive. It shuts down when fully turned down. I can live with it but...
