Multi/Pak 80 is the ideal choice for deluxe residential or light commercial baseboard heating requirements. With a choice five interchangeable H-Series Slant/Fin heating elements for hot water or steam, Multi/Pak 80 suits every requirement. Permits higher velocities, lower pump loads and longer loop runs. Multi/Pak 80 is also ideal as a supplement to Slant/Fin residential baseboard in locations where wall space is limited and higher outputs are required.
