Greetings! Mine is a 3 story house built in mid 80's, "daylight basement". Original aluminum windows, so the overall R value is less than "modern". House has twelve 220v baseboard heaters, of which we use 2 or 3 sparingly on super-cold days when highs are below 10°F. We only need them 25 days out of the year. We live at 4500', with 4mo winters, 2mo each spring and fall, and the woodstove is off duty 4mos per year. For air movement between floor 1 and floor 2, there are 3 baffled airways (two have small electric fans) plus the stairway. Once floor 2 is warm, floor 3 just seems to stay warm as well. Sooo, this KEJ 1101 has been doing the job for us for 7 years. We burn doug fir, western larch (tamarack) and lodgepole. We use 7 cord per year. We load the stove every 6 hours on average, using 5 or 6 good chunks per load. A generous load at 11:00PM will leave a decent coal bed at 7:00AM. When it's cold out, i keep the stove running at 1200° on gauge. It will dang near run you out of the basement, but it heats the whole house nicely. When it's warmer out, I pinch it down to run longer between loads; and the gauge varies between 500° and 800°. It won't run below 400, it just goes out. It's a good stove, but old and losing a few bricks inside. I'm considering replacement. Goals: 1 - Find best value in the middle price range, best balance of quality vs. price. Cannot afford top of line BK, etc. Need built-in blower system on the stove. 2 - Needs to at least meet the capabilities of existing stove, if not exceed them. Need low-slow capability for shoulder seasons, but also mild thermonuclear capability for 25 days per year of sub-10° weather. 3 - Would like to burn less wood per year. More efficiency. Does anyone here know standard efficiency specs for my existing stove? Thanks! I've done a fair amount of reading here, and will be checking out the Englander stove, but open to advice, suggestions, tips, etc. I need a big stove. I have no desire to limp on BTU's. I want to be able to make it damn hot if i need to. Thx!
