Converting a oil boiler to a gas boiler - BiggerPockets

ALOT of guys I know convert the boiler from gas to steam. Now common sense would not suggest you attach a new gas gun to a 30yr old junker boiler, but in my case my boilers were only 10-12 years old and were in good shape. It is a heck of a lot easier and cheaper to convert verses install a new gas system.

Calculating Boiler Chemical Requirements – Water

Jun 26, 2017 · Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. To develop this alkalinity, we need 25 ppm soda ash (as CaCO 3) in the feedwater (250 ppm boiler alkalinity divided by 10 concentrations), over and above the amount required to neutralize non-carbonate hardness in the feedwater.
