I am in the process of fixing my existing gas weil mclain EG-45. I may have to change the boiler so I want to make sure I'm looking for the correct size replacement. I have a few questions:

1. My existing boiler has a tankless coil water heater attachment heating the basement baseboards. If I replace the boiler with one that does not have this attachment, since this is what failed on my existing boiler and I am not sure I'll be able to fix it, what can I use to heat this baseboard circuit?

2. If going by the existing boiler without recalculating the EDR, what is a better, modern replacement for the EG-45?

Thanks again all!


EDIT: I found this thread which has good info on EDR for my AERO radiators: https://forum.heatinghelp.com/discussion/189211/sizing-new-steam-boiler-and-edr

Will start there.
