Product Description

The Sterling 800cu75-4 is a high output hydronic baseboard heater designed for residential and light commercial heating applications. This unit is part of the NST-800 series and comes complete with a 3/4 inch copper element, making it a ready-to-install solution for hot water baseboard heating systems. The 800cu75-4 delivers 3,200 net BTU at 180 degrees water temperature and 1 gallon per minute flow rate, providing reliable and consistent radiant heat output for finished spaces. At 4 feet in length, this baseboard heater is well suited for rooms that require a moderate heat load without extensive baseboard runs. The unit measures 3 and 3/8 inches thick and stands 9 and 1/8 inches tall, fitting neatly along walls at floor level where it can distribute heat evenly across the room. The heater ships in a painted white finish, matching standard interior trim and cabinetry without requiring additional painting or preparation work. It weighs 14.40 pounds, making it manageable for a single installer during rough-in and finish work. Hydronic baseboard heaters like this model work by circulating hot water from a boiler through the copper element inside the enclosure. As water passes through the element, heat transfers to aluminum fins that radiate warmth into the room by natural convection. This type of heating is valued by HVAC contractors and plumbers for its quiet operation, even heat distribution, and long service life compared to electric resistance alternatives. The Sterling NST-800 series is a trusted choice among heating professionals for new construction, renovation work, and boiler system upgrades. Note that this unit does not include a splice plate, which must be ordered separately if required for your installation layout.
