Starting to have issus with my new magnum stoker and the dealer is just avoiding me know..Thought the stove was working pretty good till it got really cold out now it's nothing but headaches.First i have 1500 square feet of spcae to heat.Basement,1st floor and 2nd floor.originaly installed the harman in the basment after running the stove on high for 4 days straight the basement was cold with no heat going upstairs.Was told to move the stove to the first floor.Did that seemed to be working oki then it got cold very little heat output from the stove unless you were within 5 feet of it.Now for some more back ground on the house.It's 1500 square feet half a double.One side is totaly protected from the elements plus it's heated.So i was told that drastically lowers the btu's required to heat my house.first year in the house we used hot water radiators with a natural gas boiler.There was single radiator in each room.Even during the coldest months i could easily heat the house to 80 degrees with no heat in the basement also no insulation either.Second year installed a 30K btu pellet stove on the first floor.Turned the water off to the first floor radiators and moved the thermostat for the boiler to the second floor. Boiler hardly kicked in during the winter.Thrid year i gutted the first floor and insualted it.Ran the pellet stove but this time the natural gas boiler only kicked in maybe 5 times the whole heating season still no heat in the basement.4th year pellet stove kicked the bucket used only gas boiler Major mistake...This year i installed an efel handfired coal stove in the basement.it would heat the basement to 95 degrees in a few hours.first floor 50 degress the 2nd floor 75 degrees all the heat was going right up the staircase to the 2nd floor.Got tired of finding ways to get heat on the first floor not to mention tending to the fire every of hours gets old real quick.bought this harman magnum stoker that is rated at 85K output btu and the damn thing can't even heat a 12 by 16 room.this is no lie the other night it dipped into the single digits came downstairs the thermosat said 45 degrees the stove which is 10 feet away said 550 degrees..What gives??Also when the dealer tech came he checked my draft with his gauge it showed 10 the specs on the stove call for .04 He has the barometric dampner fully open to obtain .04 then he checked the fire box well he ended up practicly closeing the combustion fan restrictor plate almost all the way to obtain .04 in the fire box when it's set to there specs the stove burns like crap.temp goes no higher then 350 to 450 plus i have to turn the feed rate all the way down to 1 dot. By the way 1 dot= low burn 2 dots= med burn and 3 dots=high burn. So basically the best this stove will ever run when set to there specs is a low burn.
