GRILLME Immersion Water Heater 240V 3000W — Fully Submersible Bath & Small Pool Heater with 118" Cord

GRILLME 240V 3000W immersion heater is a fully submersible electric element designed to heat bathing tubs and small pools quickly and safely when used with a NEMA 6-15P 15A outlet.

If you need a portable, high-power solution to raise water temperature without installing complex plumbing, this stainless-steel 316L immersion heater delivers rapid warming for tubs up to roughly 30 gallons and pools up to 200 gallons. It comes with a long 118-inch power cord, a 13.5-inch heater element, and a NEMA 6-15P plug requirement. Built for short-term, direct-water heating, it includes safety reminders about full submersion and appropriate water types.

How fast will this heater warm my bathtub or small pool?

The GRILLME 3000W element is engineered for fast temperature gains: it can raise 30 gallons of water by about 50°F within roughly 30 minutes under typical conditions. Heating time for larger volumes scales up accordingly, and ambient temperature, initial water temperature, and container insulation affect results.

• Rated power: 3000W on 240V (draws about 12.5A)
• Estimated: 30 gal +50°F ≈ 30 minutes
• Larger pools (up to 200 gal): slower, depends on volume and heat loss
• Results vary with outdoor/indoor conditions and container material

What electrical and installation requirements should I follow?

Use only a dedicated NEMA 6-15P 15A outlet for safe, reliable operation; this heater is designed for 240V circuits and draws approximately 12.5 amps. Do not attempt to use adapters or undervalued wiring, and keep the long power cord clear of trip hazards and chemical contact.

• Plug type: NEMA 6-15P, 240V, 15A outlet required
• Current draw: ~12.5A — avoid shared high-load circuits
• Cord length: 118 inches for flexible placement
• Element length: 13.5 inches — fully submerge when heating

What safety precautions and water types are recommended?

The heater must remain completely submerged while operating to prevent dry-burning and damage. Only use it with normal tap water; avoid corrosive or mineral-heavy liquids such as seawater, untreated well water, strong acids, or alkalis. Clean scale deposits regularly to maintain efficiency and longevity.

• Always fully submerge the heating element during use
• Not suitable for seawater, well water, acids, or alkaline solutions
• Use mild descaler or vinegar to remove scale buildup periodically
• Anti-scald sheath protects container surfaces from damage

How durable is the heater and what warranty is included?

The heating shell is stainless steel 316L, chosen for stronger high-temperature and corrosion resistance than 304 stainless steel. The unit includes a one-year warranty and free return or exchange for damage occurring under normal use, offering confidence for routine portable heating tasks.

• Shell material: stainless steel 316L for corrosion resistance
• Protective anti-scald sheath to minimize container wear
• One-year warranty with return/exchange coverage for defects
• Do not use with corrosive liquids to keep warranty intact

Who is this for: GRILLME's 240V 3000W immersion heater suits homeowners, renters, and outdoor enthusiasts who want a no-plumbing way to warm bathtubs, portable pools, or large containers of potable water. It is best for users with access to a proper 240V NEMA 6-15P outlet who follow submersion and water-type guidelines. If you need reliable, quick heating for clean tap water in portable settings, this submersible electric heater is built for that purpose.
