Utica By Dunkirk Transformer Primary Secondary Pool & Unit Heater Parts

Utica by Dunkirk replacement transformers for pool heaters, unit heaters and other hydronic heating equipment. Each transformer steps a higher primary (line) voltage down to a lower secondary voltage, usually 24V. That lower voltage powers thermostats, control boards, gas valves and other low-voltage controls. These parts are also called control transformers, step-down transformers or 24V transformers.

Key Features:

• Step-down design that converts line voltage to a safer low-voltage supply for heater controls
• Works by electromagnetic induction, giving a stable and consistent secondary output
• Helps protect control components from electrical damage and supports reliable system operation
• Replacement part from the Utica and Dunkirk heating line, made by ECR International
• Available in different primary and secondary voltage and VA ratings. Check the rating on each individual listing.

Replacing a failed transformer restores power to the heater's control circuit. Choose the primary voltage, secondary voltage and VA rating that match your equipment's original transformer.
