Home Made / putting water heater tanks on top of firebox for boiler
« on: September 15, 2011, 01:38:48 PM »
Hello folks,
I am building an outdoor wood boiler. The building is cinderblock and concrete. I am using a used 275 gallon steel oil tank for a firebox and will run a 40 psi pressurized water circulation system with either five 40 gallon lowboy elec water heater tanks above the firebox or half a dozen 80 gallon elec and gas water tanks mounted horizontally above the firebox. This room will get very hot, as I intend to run the stove pipe horizntally for many feet (it will actually have a slight upward slope). A cast iron circulating pump will cycle the heated water through heat exchangers in my furnace plenum and radiators and then into a 1,000 gallon indoor reservoir lined with EPDM to repeat the cycle. The circulating pump will be plumbed below water level. The cold water supply to the boiler room will be pex but everything in the boiler room and the hot return will be galvanized.
Will elec and gas water heaters mount horizontally? Will 6" 24 gauge stovepipe and elbows handle the heat? Is there anything on the water heaters that will melt, like the PRV's?
I have an 8,000 square foot home and a plentiful supply of free wood. I plan to leave the circulating pump and the two zone HVAC fans running continuously all winter. I live in Virginia. Many thanks in advance.
