About the Solution (non-condensing)
The Solution is the non-condensing entry in Lochinvar's residential boiler line, listed under "Non-Condensing Residential Boiler" on the same page as the Knight and Noble. The CBN045 product page shows a model selector from 45,000 to 260,000 BTU/h, and the page copy highlights the gasketless heat exchanger, intermittent spark ignition, a built-in pumped performance loop and top-located piping and venting connections for simple installation.
The CBN045 spec block prints an 84% AFUE rating, a 45,000 BTU/h maximum with a 45,000 BTU/h minimum listed, 1 1/2" water connections and an atmospheric vent using Type B gas vent — a reminder that this is a non-condensing appliance, distinct from the condensing Knight and Noble lines beside it. Boilers.ca covers the Solution for completeness because it remains on Lochinvar's current residential pages, but modern replacements are generally the condensing designs.

Frequently asked questions
Is the Solution a condensing boiler?
No. Lochinvar lists it under "Non-Condensing Residential Boiler," it is rated 84% AFUE, and its product page specifies atmospheric venting in Type B gas vent rather than the PVC/CPVC Category IV venting of the condensing Knight and Noble.
What sizes does the Solution come in?
The CBN045 product page's model selector runs from 45,000 up to 260,000 BTU/h. Boilers.ca documents the CBN045 itself, which is the model whose spec numbers appear on that page.
