Choosing an Indirect Water heater via MBTU/Hr rating

[anthonymmfalcone]

Dear Readers,

I'm trying to select an indirect water heater to retrofit my boiler from a tankless coil. The literature for indirect water heaters lists a Minimum Boiler Output (MBtu/hr.). Would this number be my boiler's "DOE Heating Capacity" or my boiler's "NET I-B-R Ratings-Water"? These are the only two ratings I can find for my boiler in MBtu/hr.

Any advise appreciated.

what are the numbers

[anthonymmfalcone]

Phase III Indirect Water Heater Model #TR-45: "140,000 Boiler Output BTU/hr" I assume that means that this model needs a boiler with an output of 140,000 BTU/hr.

My boiler: "Buner Capacity: 147MBH, DOE Heating Capacity 129 MBH"

Not sure if this means my boiler can/can't handle this model of Indirect water heater.

I would suggest that you hire a professional, before you end up spending a lot of money on something that doesn&#39;t work correctly.
