One bock water heaterBock Models 32E, 51E, 32PP and 51PP are the highest quality residential oil fired water heaters. They surpass industry standards for both combustion and thermal efficiencies. As a result, annual operating costs are greatly reduced.

Only Bock water heaters have the patented, all steel multi-finned Turboflue. It is the industry’s most advanced heat exchanger. No other concept transfers heat faster or more efficiently. Turboflue is welded to the center of the tank at the top and bottom. This construction method provides a very strong, continuous heating surface. Area where lime and sediment collect are limited and easily maintained. The outstanding heat retention of the Turboflue and thick insulation dramatically reduce standby loss.

Hot water from any boiler is circulated around a corrugated stainless steel tank for safe, efficient hot water at the lowest possible operating cost.
