The Bock 50ESLB is a high‑capacity lowboy oil‑fired water heater designed for installations where vertical clearance is limited but strong hot‑water output is essential. With its 50‑gallon storage capacity and low‑profile footprint, this model is ideal for basements, crawlspaces, and mechanical rooms that cannot accommodate a standard‑height heater. Built with Bock’s renowned cobalt‑enriched glass‑lined tank, the 50ESLB delivers exceptional corrosion resistance and long‑term durability, ensuring reliable performance even under heavy daily use.
Equipped with a factory‑installed 1.0 GPH oil burner, the 50ESLB provides fast recovery rates that outperform typical residential water heaters. Its efficient combustion and consistent ignition make it a dependable choice for households with higher hot‑water demand, multi‑bathroom homes, or applications requiring steady, uninterrupted supply. Operating on 120V/1PH/60HZ, the unit integrates easily into standard residential electrical service.
The tank’s heavy insulation minimizes standby heat loss, helping maintain stable water temperature and improving overall energy efficiency. A rugged steel jacket, clean internal layout, and accessible service points make routine maintenance straightforward for technicians, reducing downtime and service costs.
Whether used as a primary water heater or paired with a hydronic heating system, the Bock 50ESLB stands out for its combination of capacity, efficiency, and durability. Its corrosion‑resistant tank, powerful burner, and lowboy design make it a premium solution for reliable, oil‑fired residential hot‑water production in space‑restricted installations.
