Some of you already know I have an old Whitfield Advantage 2T.....Last night it was down in the single digits here in central ohio and "old girl" pulled through it tremendously....I cranked her up to #4 on the old manual dial before going to bed and woke up this morning almost in a sweat with no covers over me....Thermostat in the stove room reads 80 degrees and the rest of the house is in the mid 70's...I have a 1400 sq ft cape cod and keep a couple oil filled electric heaters running on low upstairs because its hard to get heat down the hallway and around and up the stairs...I bought this old whitfield from a guy last year for $150 and she has worked great with very few issues ever since. The great thing is I can still get parts for her if needed. Just thought I would share this with ya'all
