Slant/Fin Lynx
Model Number: LXW
A condensing gas boiler now in Slant/Fin's vintage library; see the Lynx LX page for sizes and warranty.
Technical Specifications
Some figures come from distributor listings and are still being verified against the manufacturer.
Prices depend on sizing, venting and piping in your home, so we quote every installation.
Discontinued: listed in Slant/Fin's vintage product library. If you already own one, we can still service it where parts are available. For a new install, compare current Slant/Fin models or every brand's lineup.
Sizing: the right size comes from a room-by-room heat-loss calculation, not the size of the old boiler or a rule of thumb. Oversized boilers short-cycle and waste fuel; steam systems are sized to the connected radiation instead. See how we approach boiler installation.

Expert Review: Slant/Fin Lynx
The Slant/Fin Lynx is a sealed-combustion condensing gas boiler, not a cast-iron boiler. It came in LX-90, LX-120 and LX-150 sizes covering 25,000 to 150,000 BTU/hr and vents through 3-inch PVC, CPVC or stainless pipe. Slant/Fin now files Lynx in its vintage product library, so it is treated here as discontinued. The 95% AFUE shown is a commonly cited figure not yet confirmed in Slant/Fin literature. This listing overlaps the Lynx LX page, which has the full specifications and warranty.

Sizing & Installation Notes
Condensing boilers like the Lynx reach their rated efficiency only when return water runs cool enough to condense flue gases. We check your radiation and design water temperatures so the unit actually condenses in your home, not just on the spec sheet.
Every Slant/Fin installation starts with a free in-home assessment covering the heat-loss calculation, venting and chimney condition, and gas or oil supply sizing. Learn more about our boiler installation process, or see current rebate and incentive programs that may apply.
