His reasons are that he is burning 4 bags a day, and he said his electric bill has gone up 50%. It is a FHW system, with one circulator, and 4 zone valves. The house is about 20 years old and 4,000 sq. ft. I think his coal consumption is high, the electricity usage I would have to see it to believe it. I would like to get his numbers to where they make sense.
4 Bags a day is 160 lbs of coal if they are 40lb bags if there 50lb bags then that is 200 lbs of coal in 24 hrs.
At 6 teeth that is 15lbs per hr My guess would be that 6 teeth feed would be more then enough to heat a 20 year old
4000sq ft. home. How many Hours a day is his 520 firing . IMHO that way to much coal being burned in 24 hrs.
I would check to see if the boiler is sealed to the base check the two side panels and rear one to see if they are sealed
also check the Auger tube seal coming out of the base if he is using a drum check that end to . also check the two door
seals . Check the draft in Chimney aswell as over the fire draft . Check the auger tube make sure that is all the way in the pot along with the air tube .
