: ... Why bother modulating? Just get the outdoor reset and a condensing boiler like the Dunkirk Quantum.
: You'll get almost 90% efficency and the flue condensation will not hurt the alumuminum block and save money over the higer end modles. NY Thermal's Trinity boiler is also less costly.
Thanks. But what about the indirect water heater? If I need 180 - 200F HWS for the coil, won't that prevent any savings? I realize that the DHW can be prioritized and I would be running the boiler "hot" for the winter (mid-Oct thru mid-May here in MA), but what about the rest of the year (5 months)?
