The input btus is 140k, the output around 106k which is max firing. I think your trying to push something that won't be able to keep up unless you fix the other issues in the home. If you can't heat 1000sq ft then something isn't right. We took our 2400 sq.ft victorian with 10' ceilings from 69 to 71 where the thermostat was set in 20 minutes this morning. It was 0* out and the windchills were below zero. Plus our old basement was warm. I would recommend an energy audit on your home to pinpoint where the trouble spots are. We had a blower door test done for free from our local electric co-op. It may be the best money spent.
