Laars 9600 CB Boiler Overview

The LAARS 9600 CB boiler, also known as the Heatmaker, is a discontinued condensing hydronic boiler. It has a seasonal efficiency of up to 88.7 percent AFUE and a thermal efficiency of 96 percent. The unit uses either natural gas or propane.

The 9600 has a dual heat exchanger design in which the primary exchanger operates in non-condensing mode and is made with a copper coil. The stainless steel secondary exchanger surrounds the primary coil. A built-in circulator allows enough pressure to circulate water through the heat exchangers and a secondary storage tank, and all waterways are made to be resistant to corrosion. The sealed combustion system is self-monitoring and the system’s Integrated Boiler Control monitors the hot surface igniter.

While noted by many for its efficiency, the LAARS 9600 boiler was discontinued in March 2007 as part of a voluntary recall. The plastic venting components used in the design are reportedly susceptible to cracking, thereby allowing flue gases such as carbon monoxide to leak into the home. A free replacement of the affected parts can be arranged through Laars using kit number R206077.

Other 9600 CB Reviews

Laars 9600 is mentioned on the HVAC discussion forum heatinghelp.com as being one of several HVAC manufacturers that does not provide quality information on parts and service information. Chief among the complaints posted here is that the manufacturer sells repair kits, rather than individual parts. A contractor on the site points out that when repairing a bad o-ring, he wound up paying for a full set of expensive repair pieces in addition to the one inexpensive part actually needed. Several other contractors then chime in to mention they too have seen problems with dripping thermostat housings that could likely be repaired simply by adding a new gasket.
