I purchased a Maxim 250 last September and started it on October 1st. The unit is 300 feet from my house and I am heating approximately 2300 Sq/Ft older home. I have no trouble keeping my house at 72 degrees even when its -45 with the wind chill. January and February has been brutally cold up hear in Northern Maine and I average 3 to 4 bags a day. My over all average since they day I fired it up on the 1st of October is 2.9 bags per day. Ashes are not to bad, I clean the stove every 2 to 3 weeks and it takes me approx. 20 min. I switched to the Maxim from a Central Boiler outdoor wood boiler which I ran for 11 years. I was burning approx. 15 cords year, I figure I will burn approx. 12 tons of pellets with the Maxim. Pellets are more expensive than woods but the convenience is worth it for me. I have no regrets switching to the Maxim all though the customer service could be better.
