Crown Bimini BWC150
The Crown Bimini BWC150 is the 150-MBH-class floor model of the MCBA-control BWC generation (LP suffix for propane): an aluminum condensing boiler firing 50–150 MBH with 133 MBH DOE heating capacity and a 117 MBH net water rating over 3 sections, with a 4" vent-collar inlet and 3" exhaust collar.

Crown Bimini BWC150 in practice
The Bimini BWC150 belongs to the MCBA-control generation of Crown's legacy BWC condensing family (the later floor models BWC150/BWC225 documented in the MCBA-generation installation manual). Its specification-table row prints a 150/50 MBH maximum/minimum input, 133 MBH DOE heating capacity and a 117 MBH net water rating over 3 sections, with a 4" vent-collar inlet and 3" exhaust collar.
The BWC boilers use aluminum heat exchangers constructed, tested and stamped in accordance with ASME Boiler and Pressure Vessel Code Case 2382-2 per the installation manual, which notes some jurisdictions do not recognize that Code Case. Models shown are for natural gas; add the LP suffix for propane (for example BWC225LP) and performance ratings are the same for both fuels.
The Bimini is legacy: it appears only in the frozen crownboiler.com navigation and is absent from the current Velocity Boiler Works menu, so productStatus is 'discontinued'. The manual prints no AFUE figure, so none is stated here. No official Canadian-sales statement was found, so canadianStatus stays 'unknown'; service work belongs with a licensed contractor.
Best suited to
- Owners documenting an installed MCBA-generation Bimini against the correct manual
- Contractors researching the BWC150/BWC225 floor models and their vent collars
- Legacy-replacement planning where the rating-plate generation must be matched
