Boiler Ratings part 17, Reviews of the Westinghouse, Williamson, Wolf, & Zantia brands



These boilers are made by HT PRODUCTS INC. but their warranty is not very good when compared to other brands. The PREMIER high efficiency unit can be floor standing or wall mounted and is available in seven sizes to match the needs of virtually any home. Their FIRE TUBE BOILER is the next generation in boilers and is a wall hung unit. It has a durable stainless steel heat exchanger and modulating ability with an outdoor reset temperature control for added energy savings. 


This brand offers a wide variety of boilers that are made of cast iron. They have stainless steel burners for durability and a built-in air separator to keep air out of the system. The FREESTYLE model (shown here) is a wall-mounted condensing boiler with modulating ability. They feature a durable stainless steel heat exchanger and are available in three sizes. The warranty on the heat exchanger is good but the guarantee on most other parts is not as good as other brands. The GWA model is a basic boiler that uses atmospheric combustion. It has a large external draft diverter which takes up added space but it has a built-in air separator. The GWI models use a draft inducer which allows for sidewall or chimney venting for flexibility. The brand is available in the USA but only through their factory authorized distributors.


The FNG models are floor standing premium gas boilers with stainless steel pre-mix burners and the CGB-2 are wall mounted condensing boilers. Their website is not much help and does not have a stated guarantee for their products. The brand is a part of CENTROTEC AG. 


This brand offers a wide selection of models and is available worldwide but their dealer network is limited. The FLORENCA wall boiler is available in both high temperature and low temperature versions. They have built-in pumps and three independent heating circuits. Their website does not have a stated warranty policy.
