Been reading this forum for awhile, reviewed many options and decided to make the jump to coal. Been heating home with propane boiler, hot water coil in air handler and indirect DHW heater until $$$$ for propane in
2006. Fired up a radiant wood stove in the basement every year since burning 2.5 to 3.5 cords to heat 2700 sq ft of 1st and 2nd floors by cutting an opening in the return air duct close to stove. Natural convection most
of the time and warm floors from the radiant heat [basement toasty]. Much to the families delight [and wife] we will put the aa130 with coal bin in a shed right outside the house. Need 30ft of piping in house and roughly
12 outside up into shed. I would like to burn 24/7/365 for heat and DHW. I did read all the excellent thoughts posted to "needs help asap". Bought a 1960 AA130 from Glenn Harris [what a guy, thanks Glenn] and going
over that unit, few bushings, seals and gaskets. OK> I will be parralleing into the existing boiler. Any thoughts on pipe size? Running circulator all the time or just when one of the 3 loops calls for heat? Circulator size?
[ the shed floor will be lower then the 1st floor due to outside grade by 2 ft or 6 ft above boiler } Using black pipe vs. copper in the house? Dump zone ??? I will put radiators in the basement now since the wood stove is retired
to occasinal hot dog duty. Should we use the original design of controls on the boiler or go electronic? [should i have multible posts?]
