Well still burning next winters coal , but now I have more coal in the ash , this boiler doesn't like to burn at idle ,i burn all summer to heat my water .(is the coal left in the ash because of timer set to long or because fire box temp to low) ! I don't know if this can be regulated any more to have less coal in ash or not ,
my boiler has been burning for 6 years straight and i just have been servicing her while shes been burning , been a good girl so far ,hope she has 50 more years in her !!!!
