PRODUCTS: Utica Boilers - Hotline Series Indirect Water Heater
FROM: ECR Technical Service Department
Subject: Coil Change

Models Effected: HL-30, 40, 50, 80 & 119

Description of Change

Effective immediately the HotLine Series Indirect Hot Water Heaters have changed as follows: (see illustration below)

• HL30, HL40 & HL50 have relocated their “boiler/coil in” and “boiler/coil out” tapings. Previously on the top, these
connections are now on the side of the tank.

• All HotLine sizes (HL30 - HL119): Internal coil diameters have increased from ¾” to 1-¼”. Coil connections for all
sizes will now be 1-inch NPT.

NOTE: The change in the coil does not effect the location or size of the domestic Hot and Cold connections.

New 1-1/4” Coil

“Boiler/Coil In”

(1-inch NPT)

“Boiler/Coil Out”

(1-inch NPT)

Reasons for Coil Change

• Better heat transfer due to more coil surface area resulting in improved output (recovery rate) of the tank.

• Improved flow through coil due to lower head loss.
