Williamson-thermoflo Gsa-075 - 47k Btu - 83.0% Afue - Steam Gas Boiler - Chimney Vent Review Aug 12, 2016

New Boiler Sep 16, 2016

just purchased this boiler for my home and it was by far the best choice. If you have any questions you can just call LAARS HQ and talk to a person immediately.

Installed in a day. LOVE THE HEAT!

System Reliability Oct 02, 2016

Two days after installation, the 12k unit quit working with a fan malfunction code. Efforts to contact Gree have been unsuccessful. The 9k unit continues to operate normally. Warranty/repair is a real issue.
