Sxmprail 1500W Submersible Stock Tank Heater for Rubbermaid Troughs — Thermostatic, Copper Element, 1½" Fitting

The Sxmprail 1500W submersible stock tank heater is a thermostatically controlled replacement designed to keep Rubbermaid and other plastic stock tanks ice-free and livestock water accessible in cold weather.

Built as a direct-fit alternative for common Rubbermaid trough models, this submerged heater combines a precision temperature sensor, durable copper heating element, and reinforced sealing hardware to deliver reliable winter water management. It installs through the tank’s drain hole and runs only when temperatures fall, reducing runtime and lowering the chance of unnecessary power use.

How does this heater prevent my stock tank from freezing?

The Sxmprail unit uses a thermostat-controlled copper heating tube that activates when water temperature drops. It cycles on and off to maintain liquid water without running continuously, which preserves energy while preventing ice buildup.

• 1500W copper heating element for fast heat transfer and corrosion resistance
• Thermostat triggers below about 41°F and stops at higher temperatures to save energy
• High-density silicone fill and gaskets guard against leaks and electrical faults
• Concealed, submersible placement reduces risk of animal interference

Will this fit my Rubbermaid tank and how do I install it?

The heater is intended for standard Rubbermaid stock tanks (50–300 gallon models) but requires a drain-hole diameter larger than 1.75 inches. Installation is straightforward: insert through the hole, tighten the locking nut, choose gasket placement for the best seal, and plug in after activating the thermostat.

• Compatible with multiple Rubbermaid models (50/70/100/150/300 gallon sizes)
• Threaded 1-1/2" MNPT fitting; nut thickness and deep threads improve grip
• Includes two flexible silicone gaskets for inside/outside sealing options
• Compact 10 × 5.5 inch submerged body stays out of animals’ reach

What materials and safety features protect the heater and livestock?

Sxmprail emphasizes robust construction and electrical safety. The heater uses high-purity electrolytic copper for efficient heating and corrosion resistance, while a thick PA plastic housing and silicone gaskets provide durable sealing under pressure.

• Premium copper tubing for fast, long-lasting heat performance
• High-hardness PA plastic housing resists wear and prevents loosening
• 8mm nut and extra-deep threads reinforce the watertight connection
• High-density silicone fill reduces leakage risk and helps prevent GFCI trips

How energy-efficient and serviceable is the unit?

The thermostat-driven design limits power consumption by operating only when necessary, reducing unnecessary heating hours. Sxmprail backs the heater with a three-year free replacement policy and responsive support to address installation questions or defects.

• 1500W rating with automatic cycling based on ambient/water temperature
• Stops heating when temperatures reach safe thresholds to conserve electricity
• Three-year free replacement commitment for peace of mind
• Customer support response typically within 12 hours via seller messaging

Who is this for: This Sxmprail submersible tank heater is suited for farmers, ranchers, equestrian facilities, and anyone using Rubbermaid or similar plastic stock tanks who need a reliable, tamper-resistant solution to keep water unfrozen during cold months. It benefits users who want a straightforward installation, durable components, and thermostat-controlled operation to balance animal safety and energy use.
