About the P-K SOLIS
Patterson-Kelley describes the P-K SOLIS as the boiler that 'leads Patterson-Kelley into the condensing firetube market': a vertical firetube design with 96% efficiency, 10:1 mechanical turndown and ultra-low NOx printed on the official page.
Model sizes are organized on per-family pages whose documentation rows reference ranges such as 725–1000, 1500–2000 and 2500–3000 MBH; the exact model steps live in the submittals rather than the page copy, so Boilers.ca does not print a size list it could not verify.
Each P-K product page carries an engineer-library set of public PDFs (I&O manuals, submittals and brochures); the SOLIS submittal and brochure are linked from this hub. No official Canadian availability statement was found.
