I’m very interested in this. For how long have you been doing it? I’m trying to help a man live without central heat and thought we could get a heat lamp and leave it in the kitchen, only on when he is working there. Then use the space heater in the area where he mostly lives. Maybe we’ll find that heat lamps work better and use those both places, that would save electricity. Can you tell me if you used a special kind of lamp for it? Thanks!
