Our Coop uses the main boiler to heat water year round.

We have a large Steam boiler. With a relatively modern burner. I believe the this boiler type is called and indirect boiler. Meaning the (chemically treated) boiler water is never mixed in with the water supply.

My question is: is it really necessary to heat up the huge amount of water in the boiler to get hot running water? Also it usually takes a while before that hot water gets to where it’s needed, would having a small boiler ready to go improve the situation?
Is it possible to connect a small boiler in sequence to the big one? Meaning if the large boiler already made heat and heated water, then use that water for the hotwater supply, and If the water coming from the big boiler is not hot then heat it in the small boiler.
Or if for example it’s is the peak of hot water usage and the small boiler is not keeping up with the hot water demand could it signal the Big boiler controller to make hot water and then mix that with the water from the smaller boiler.
