I am trying to get my thoughts around running my stoker year around. it is a 1953 EFM high boy.
Does anyone know at what point you can justify running the coal vs letting your electric hot water heat your water?
I dump my coil into my hot water tank sort of like a holding tank. if the temp in there goes below 120 or so the electric will heat it.
But I was just not sure if anyone did the cost analysis! Summer is a long way off for now but I like to plan ahead. I bought this baby in April last year just to get it up and running for the fall.
In the Summer time if you set it to 3 teeth which is 7.5 lbs a hr and set your timer to run 2 min. every hr that will be 2 hr
a day of burning coal which will be 15lbs a day to heat you water aqaustat set at 140f low or you can set it to 2 teeth
which is 5lbs a hr at 2 min every hr 2 hrs a day of burn time will be 10lbs a day yo could drop it to one tooth which is 2.5
lbs a hr at 2min every hr which is 2 hr a day of burning you would be at 5 lbs a day but i don;t think you will have very hot water the BTU's would be to low I am running 3 teeth now with out any problems I will be testing 2 teeth in the summer time to see how it goes right now 3 teeth is keeping the house at 73f and the water very hot 140f to 170f high limit is
180f have not hit that yet The T stat hits the set temp first but like I always say what works for one my not work for
other's And I am Sorry For High jacking this thread can't help myself sometimes
