Biomass Boiler Ratings part 23, Reviews of the Woodco, Woodmaster, & Zantia brands


This brand was formerly known as WES (Wood Energy Solutions) and their products are available in Europe as well as the USA and Canada. The E-COMPACT TWIST boilers are state of the art condensing boilers that burn wood pellets. They have a durable stainless steel spiral heat exchanger as well as automatic feeding and cleaning. The COGEMAX units are micro-chp units that can provide up to 2.8kw of electricity for the home as well as providing the hot water for the central heating system.<1* 

This brand is made by NORTHWEST MANUFACTURING INC. The MINI BOILER features automatic operation and an air cleaned firepot as well as a large ash box to minimize the need for dumping the ashes. The ULTRA series units are installed outdoors and feature automatic operation. The guarantee on the heat exchanger is not as good as other brands and the units are only available through their authorized dealers which is rather limited compared to other brands.<1*

The ARIDA model boilers can burn almond shells, olive pits, etc. as well as wood pellets. They are auto-cleaning and have electronic controls. The brand offers a variety of other models but their website does not have a stated warranty policy.
