Slant/Fin HWT Indirect Fired Storage Water Heater

Slant/Fin HWT40 Indirect Water Heater


The Slant/Fin water heater is connected to your boiler just like a heating zone. Hot water from your boiler circulates through a heat exchanger coil built into the center of the water heater. The hot coil then heats the domestic water in the tank. Since each system is totally sealed, water from the boiler is never mixed with the storage water. This heating "loop" is only activated when the temperature of the water inside the tank drops below the control temperature. Hot water in the carbon steel storage tank stays hot longer because there's no flue heat loss plus the tank is protected by an environmentally friendly polyurethane insulation. A carbon steel smooth tube heat exchanger coil with titanium enamel coating restores full water temperature two to five times faster than direct-fired units. The coil is continually scrubbed clean by the flow of incoming water so it resists mineral build-up and its large diameter keeps pressure drop low.

  • Supplies abundant hot water
  • Equipped with its own heat exchanger coil, it offers better efficiency, faster recovery and longer life than a gas or oil direct-fired water heater
  • Efficiency: Standby loss less than 1° per hour
  • Long life glazed-titanium glass liner for added strength and durability
  • Carbon steel tank resists rust and corrosion
  • Supplied with two magnesium anti-corosion anodes
  • Environmentally friendly polyurethane insulation limits heat loss and is both CFC and H-CFC free
  • All fittings are female NPT thread connections
