The SuperStor ultra indirect water heat is a culmination of over 30 years of indirect system manufacturing experience. The 316L stainless steel tank resists corrosion and eliminates the need for anode rods, allowing for the system to be virtually maintenance free. The heater draws energy from a boiler and thus does not need its own heat source. Hot boiler water flows through an internal heat exchanger in the tank, heating the domestic water. The SuperStor boasts three to five times more recovery than conventional gas-fired or electric water heaters.
  • Stainless steel internal bent hot water outlet tube
  • Attractive silver finish cover that resists dents and corrosion
  • High output finned cupronickel heat exchanger provides maximum efficiency 11 fins per"
  • 316L stainless steel tank for high temperatures and corrosion resistance
  • Environmentally safe, CFC free water blown, 2" thick foam insulation allows less than 1/2 deg F heat loss per hour
  • Immersion type stainless steel control well

Therma-flow/everhot series hot water boosters have been specifically designed to eliminate service problems. All fittings have been positioned for front access, enabling the units to be conveniently installed even in tight corners. In addition, the anode rod can be removed without dismantling the jacket top and related water pipe connections. The installation of a therma-flow/everhot hot water booster will enable the present boiler to operate at a lower temperature, thereby reducing overall fuel consumption.
  • High density fiberglass insulation
  • Heavy gauge steel jacket
  • Equipped with immersion type aquastat, bronze circulator
  • 5 years guarantee

Bock Water Heaters SideKick 40SK Powder Coated Steel Indirect Water Heater, 38 gal, 8 gpm, 89000 BTU/hr
  • Single-wall full throat 1-1/2" diameter internal coil heat exchanger
  • Factory installed aquastat on all models
  • Factory installed temperature and pressure relief valve and brass drain valve
  • Robust construction - inner tank is precision built from high quality steel and repetitive pressure testing assures the highest quality
  • All steel construction with an environmentally-friendly powder coat finish providing a tough and attractive exterior
  • Cobalt-enriched porcelain enamel glass lined tank and coil are highly resistant to aggressive water not susceptible to damage due to the presence of chloride in the water
  • Ecomate insulation does not contribute to global warming
  • Two magnesium anode rods - inhibit corrosion and maximize tank life. Electrolysis attacks the anode rods, not the tank
  • Factory installed dielectric nipples on boiler connections - provides greater insulating protection
