Multiple boiler systems have been used for decades. They allow full heating capacity to be delivered when necessary, while also retaining high efficiency under partial load conditions compared to a single large boiler.
Most hydronic heating systems that have renewable energy heat sources, such as solar thermal collectors, an air-to-water or geothermal heat pump or a biomass boiler also have an auxiliary heat source.
ADEY’s MagnaClean DRX magnetic dirt filter provides a cost-effective solution for removing debris and black iron oxide sludge from commercial hydronic heating systems.
