This brand is manufactured by Piney Manufacturing and is available in North America. The OPTIMIZER 200
features a four pass heat exchanger and air injection both over and under for a clean efficient burn.
The units are available in four sizes to fit the needs of the home. The ULTIMIZER units have a
refractory brick lining for more efficient, cleaner combustion. The warranty is good but it requires an
annual boiler water sampling. portageandmainboilers.com
