API Stock Tank Deicer and Water Heater - Sinking 1500W (Made in USA)

In this review of the API Stock Tank Deicer and Water Heater the bottom line is simple: this sinking deicer is for livestock owners and pond keepers who need a safe, reliable way to keep 70-100 gallon tanks from freezing. The reviewer found it especially useful where plastic tanks are used because the weighted stainless steel heating element stays fully submerged and reduces exposure to air. Installation is straightforward and the unit's CSA and UL listings, plus being made in the USA, make it an attractive choice for anyone prioritizing durability and safety.

Key Features

• Safe for plastic tanks: The weighted heated element stays submerged to prevent contact with plastic walls and reduce warping or damage.
• Stainless steel heating element: The stainless construction discourages rust and corrosion so the unit stays functional season after season.
• Heating capacity: Designed to maintain liquid in tanks roughly 70-100 gallons, which matches common stock and small pond sizes.
• 6 ft anti-rub power cord: The cord length and abrasion-resistant jacket provide flexibility in placement while resisting wear.
• Certified safety: CSA and UL listings give confidence the deicer meets recognized safety standards for outdoor use.
• Made in the USA: Local manufacturing supports quality control and parts consistency.

Who It's For

This deicer is best for ranchers, horse owners, and small aquaculture keepers who use plastic or metal stock tanks in cold climates and need to prevent icing without complicated mounts or heaters that float. It is particularly suited to single-tank setups in barns or outside troughs where a sinking element and a short cord reach an outlet.

Those with very large ponds, in extremely severe arctic conditions, or who need remote temperature control should look elsewhere; this unit is optimized for 70-100 gallon applications and straightforward, local installations rather than multi-zone or high-capacity heating systems.

Pros & Cons

Pros

Cons

• Heating capacity is limited to roughly 70-100 gallons, so larger tanks need a different model or multiple units.
