Garage heat with a 9.6 kW electric heater
I have a 20X20 detached garage with no insulation (paneled inside .. no
sheetrock) and a lousy seal on the big door. I run a 4.5KW electric heater when I want to be comfy. If it is 40F out there and I plug it in then I am comfortably warm 60ish in about 15-20 min. In an hour I am taking off my quilted flannel shirt I have anti fatigue mats on the floor that help keep the feet warm. I do set it so it points at the area I will be working in. It rarely gets below 30F during the day here. I would just set the duct heater on the floor and fire it up to see if it heats well enough to be made fancy. Glenn "Ignoramus24987" wrote in message ... I have a approximately 20x20 ft attached garage. Sometimes I want to make it warm quickly. Often I am there for relatively short periods of time (because I am constantly interrupted). I bought a 9.6 kW, 240V duct heater on ebay. It has a 24V control and various overheat protections. My plan is to enclose it into a welded frame and sheet metal (found a few nice sheets in a hospital dumpster), add a fan to it and a 24V control system using a thermostat. I also have a grill type thing that I can use to protect the coils from little curious fingers and flammables. My idea is to make something relatively compact (say 2x2x1.5 ft), that I would set on the floor, turn on and get the garage warm in a few minutes rather than wait for a long time. I would save some electricity by only heating the garage when I need it, rather than warming it up "just in case". What I am looking for is some feedback on safety and such. i |
