Current oil steam & HW baseboard; going to gas, worth converting to all HW BB?
I currently have an oil steam & hot water boiler serving 3 hot water baseboard zones (part of prior homeowners renovation 10yrs ago) and a steam zone (running upstairs and downstairs) with cast iron radiators in the old part of the house (1930s). We've only been in the house for 1 winter (Massachusetts) and there weren't any major issues I noted, other than a ridiculous heating bill. Separate propane-fired hot water tank will get replaced.
Converting to gas, and trying to decide whether its worth the additional cost & headache of turning the steam zone into 2 hot water baseboard zones (one up, one downstairs) and thus only having a single high-efficiency hot water boiler. There aren't any slam dunk routes to run piping for baseboard, so it may get a little messy.
So the main questions I have are:
How much less efficient will the combo steam/radiator & hot water/baseboard set-up be vs a strictly hot water baseboard.
What are some of the better gas-fired steam & hot water boilers?
Does it make any sense to have 2 separate, smaller boilers - one for the hot water zone and one for the steam?
Can I do an indirect fired hot water tank of a steam boiler.
Let me know if you need any additional details or clarifications.
