The Spectrum Series boilers and water heaters offer the highest thermal efficiency available in atmospheric combustion today and is the only product in its size range, which uses 7/8″ inside diameter, finned copper tubes in the heat exchanger. Larger diameter tubes handle higher flow rates and provide longer service life than competitive models that use 5/8″ tubes. They are available as residential heating boilers or light commercial water heaters from 100,000 to 399,000 BTU’s. Spectrum Series boilers and water heaters are available with corrosion-resistant, brushed stainless steel jackets which makes them ideal for outdoor or indoor installation in corrosive or harsh environments. The Spectrum’s diagnostic control panel for easy troubleshooting […]
