Utica SVB-3 in practice
The SVB-3 is one of the SVB Series 4 sizes Utica prints in its official sell sheet: 75 MBH fixed input for 63 MBH heating capacity and a 55 MBH net AHRI water rating at 84% AFUE, with 3 gal of boiler water, 14¼ × 29 × 23¼ in cabinet dimensions and a 265 lb shipping weight.
It is a non-condensing cast-iron boiler with an induced-draft fan that allows flue gases to be exhausted through a chimney (4") or sidewall (3") vent — Utica positions the venting flexibility for new or existing homes with or without a chimney. The control is a recessed Honeywell high-limit/electronic-ignition design with digital temperature display, diagnostics and plug-in connections for the inducer fan and system pump; the cast-iron sections use cast-iron push nipples and the burners are titanium composite.
Safety devices include a flame roll-out safety shut-off (fuse link) and a pressure switch (vent safety shutoff) with a spare fuse link included, and Utica prints a 20-year non-prorated limited residential warranty. Official discrepancy to note: the product page text says 'six sizes from 42.5 MBH to 187.5 MBH' while the current sell sheet prints five rows (SVB-2 through SVB-6) — Boilers.ca models the five printed rows. The category card carries the 'Current' tag (checked 2026-09-09), and gas, venting and combustion work belongs with a licensed contractor.
Best suited to
- Homes whose heat-loss calculation fits 75 MBH of fixed input
- Retrofits with or without an existing chimney (chimney or sidewall venting)
- Owners of an installed SVB identifying their size and documentation
