We have been using our Whitfield Advantage II insert (with a thermostat usually set at 72 degrees) 24/7 each winter since 1996 as our primary heat source. We heat 1300 sq ft (2 story condo). From the beginning, we seem to use more pellets than other stoves installed in other condo units. We like it a little warmer than them. A bag of pellets lasts us about 24 hours at most. We are wondering if technology has improved enough to warrent replacing the insert? Today we took a serious look at a St Croix York insert. It claims the small hopper that holds only 40 lbs will last UP to 33 hours. That makes it sound a lot more efficient than what we have. We weren't looking to replace the stove, its just something we started talking to the salesperson about while there looking at prices & availability of pellets. We love our current stove. Would never go back to our electric heat. ACK! We've never needed maintenance in those 13 yrs. We do regular cleanings and its profressionally cleaned once a year by the chimney sweep, but he seems to do about the same quality job we do on the stove. We are warm. Just wondering if we can do better on pellet usuage since the availability & price has gone up on pellets and just keeps going up. We USUALLY burn New England or Dry Creek. This year all we could find when I finally got around to buying was Euraka pellets. We might actually be going thru less pellets with these even with this frigid winter. Opinions on replacing? Opinions on St Croix? Opinions on old Whitfields versus inserts on the market today? Thanks.
