i have a electric heater in my garage currently that does an ok job but its not spectacular. for instance yesterday at noon it was 32° in the shop and i kicked the heater on and at 4 it was 50° and stayed there the rest of the night. the temp outside had also risen from 34° to about 45 at 4 and then back into the high 30s at 7 when i went inside. i cant really say how much the heater actually helps but it usually raises temps in the garage about 10°-20°
the shop is a 2 car garage 24x28 with r13 in walls and r19 in the 8ft ceiling. the garage door is not insulated
the heater i am using is a 1500 watt 120v model. i am thinking about getting a second similar heater, do you guys think it would make much difference? id love to get it up to the 60s on these cold days so i could do some finishing
id really like to get something larger (240v) but cant really afford anything bigger right now. gas heaters are not an option for me either
