Simply stated, if your boiler had an output of 100,000 BTU and a normal design temperature drop of 20°: 100,000 / (500 x 20) = 100,000 / 10,000 = 10 GPM Your water flow would be 10 GPM. The next step would be to calculate the resistance to flow in your system, referred to as "Feet of Head".

Sizing a Modulating Condensing Boiler - GreenBuildingAdvisor

It's generally better to size the indirect for the domestic hot water load (typically the biggest tub you have to fill) and the boiler to the space heating load. Zoned as a priority zone, a 60K condensing boiler delivers heat to the indirect about 2x as fast as a typical non-condensing 50 gallon standalone hot water heater.
