  • 1000 W output delivers rapid liquid heating
  • 120 V single-phase supply fits standard mains circuits
  • 15-1/2 in overall length suits compact tank openings
  • 23 W per sq in density balances speed and sheath life

HVAC Control Immersion Heater

The Tempco TSP02217 is a screw plug immersion heater rated at 1000W for 120V AC single-phase supply. It fits a 1 1/4 in NPT opening and has an overall length of 15 1/2 in with a minimum immersion depth of 12 3/4 in. The steel sheath and steel screw plug are built into a NEMA 1 enclosure for general indoor HVAC control applications.

Suited for Direct Liquid Heating

This heater suits maintenance teams and OEMs who need a compact 1000W element for tanks or vessels with a 1 1/4 in NPT port. It is not for installations that require a larger flange connection, a higher voltage supply, a greater wattage output, or a longer insertion length than 15 1/2 in. Buyers needing explosion-proof or NEMA 4 enclosures should look elsewhere.

1 1/4 in NPT Thread Decides Fit

The single specification that decides compatibility is the 1 1/4 in NPT thread size. The tank or piping must provide this exact opening for the steel screw plug to seal correctly. If the available port is a different thread standard or diameter, the heater cannot be installed.

Questions about this item

How much heat does the 1000 W rating actually deliver once the heater is installed in a tank?

The element supplies 1000 W of heating power at 120 V AC single phase, with a watt density of 23 W per square inch of sheath surface.

What does the 1 1/4 in NPT thread limit in terms of tank connections?

The 1 1/4 in NPT screw plug fits a matching threaded opening; it cannot be used with smaller or larger pipe threads without an adapter.

What minimum tank depth is needed so the 15-1/2 in heater fits and operates correctly?

The heater requires at least 12 3/4 in of liquid immersion depth, so the tank must be deep enough to cover that length of the sheath.
