🎀Earthtec Portable Pool and Tub Heater – 1500W Immersion Water Heater
Hot Water Anywhere. Earthtec 1500W Portable Immersion Heater — Stainless Steel Heating Element — Heats 5 Gallons to 100°F in ~25 Min — 127V AC — 32.5in Cable — For Bathtubs, Pools, Sinks, Buckets & Camping.
Introducing the Earthtec Portable Pool and Tub Heater — a 1500W immersion water heater built around a stainless steel coil heating element with insulated heat-conducting construction for even heat dissipation and long-term durability. The compact 11.5-inch heater body with a 32.5-inch cable plugs directly into a standard 127V AC outlet and submerges into any water-filled container: bathtubs, inflatable pools, wooden barrels, sinks, buckets, and washbasins. At full 1500W power output, it heats approximately 5 gallons of water to 100°F in around 25 minutes, making it the practical solution for hot water access during camping, travel, power outages, and everyday home use where fixed hot water supply is insufficient or unavailable.

⚡ 1500W. 5 Gallons to 100°F in ~25 Minutes. Understanding the Heating Numbers.
The benchmark is 5 gallons → 100°F → ~25 minutes at 1500W. To estimate your heating time:
— Container volume: divide your container volume in gallons by 5 and multiply by 25 to get the approximate minutes to 100°F. A 10-gallon container takes approximately 50 minutes to reach 100°F from cold tap water.
— Starting water temperature: the benchmark assumes a typical cold tap water starting temperature. If the starting water is already warm (e.g. cool tap water in summer), the heating time will be shorter. In winter, cold ambient temperatures reduce heating speed — the same 5-gallon container may take 30–35 minutes in cold weather.
— Target temperature: 100°F is a warm bath temperature. For a hotter target (110°F), add approximately 10–15 minutes per 5-gallon unit. Always measure with a thermometer before use.
— Maximum use time: 3 consecutive hours — do not operate the heater for more than 3 consecutive hours in a single session. Allow the unit to cool completely before a subsequent heating session.
🚣 Bathtubs. Pools. Buckets. Camping. One Heater, Every Container.
⚠️ Read Before First Use. Safety Is the Starting Point.
2. Fully submerged operation only — the heater must be completely submerged during operation. Partial submersion concentrates heat in the exposed section and is a fire hazard.
3. Do not touch water during operation — do not put your hands or any body part in the water while the heater is plugged in and operating.
4. Do not run dry — never operate the heater with no water or insufficient water in the container. Dry operation will damage the element immediately and presents a fire risk.
5. One heater at a time — do not operate two immersion heaters simultaneously on the same circuit. Two 1500W heaters draw 3000W, which will overload a standard 15A circuit (rated for 1800W continuous).
6. Do not combine with other high-power appliances — do not run the heater on the same circuit as other high-draw appliances (hair dryers, space heaters, microwaves).
7. Maximum 3 consecutive hours — do not operate continuously for more than 3 hours. Allow to cool fully between sessions.
8. Unplug before removing from water — always unplug from the wall outlet before removing the heater from the water.
9. Keep away from combustibles outdoors — when using outdoors, maintain clear distance from dry grass, fabric, paper, and other combustible materials.
10. Inspect cable before each use — do not use the heater if the cable shows cracks, fraying, or damage to the insulation. Damaged cable insulation is a shock and fire hazard.
- Fill the Container with Sufficient Water — Ensure the container has enough water to fully submerge the heating element with the water line above the element at all points — the element must remain fully submerged throughout the heating cycle — if water level will drop during heating (evaporation in a small container), start with a higher water level to maintain full submersion as the session progresses.
- Place the Heater Fully in the Water — Submerge the heating element completely in the water before any electrical connection is made — confirm the full length of the coil element is below the water surface — position the heater so the cable exits the container at the rim and hangs clear of the water, with the plug end dry and away from the water surface — the 32.5-inch cable provides sufficient length to reach a standard wall outlet from the center of most home containers without requiring an extension cord.
- Plug Into the 127V AC Outlet — With the heater fully submerged and the plug end dry, insert the two-pole plug into the 127V AC wall outlet — confirm the outlet is a dedicated circuit or a circuit without other high-power appliances running simultaneously — the heater draws approximately 11.8 amperes at full power, which is within the continuous current rating of a standard 15A circuit when operated alone — the heater begins operating immediately on connection — there is no power switch or indicator light: operation begins at plug-in and ends at unplug.
- Monitor Heating Progress — Do Not Enter the Water — Do not touch the water with hands or body while the heater is connected and operating — monitor the heating session by timing and by periodic temperature measurement with a thermometer after unplugging — use the heating time estimates to gauge when to check temperature — do not exceed 3 consecutive operating hours in a single session.
- Unplug From the Wall Before Removing — When the water has reached the desired temperature, unplug the heater from the wall outlet first — wait 30 seconds after unplugging for any residual surface heat on the element to dissipate — then remove the heater from the water using the insulated handle — verify temperature with a thermometer before use — the element will be hot immediately after removal: allow to cool on a heat-safe surface before storing.
- Store in a Cool, Dry Place After Cooling — After the element has cooled completely, store the heater in a cool, dry location — coil the cable loosely around the heater body for compact storage without stressing the cable insulation at bending points — inspect the cable insulation and plug prongs before each use session and do not use if damage is observed.

Common Questions, Answered
Can I use this in an inflatable kiddie pool?
Yes — the heater is suitable for small inflatable pools. The key requirements are the same as for any container: the element must be fully submerged throughout the heating cycle, and you must unplug the heater and remove it from the water before anyone enters the pool. Do not operate the heater while anyone is in the water. For a typical small kiddie pool of 50–80 gallons, heating time to a comfortable temperature will be several hours — plan accordingly and stay within the 3-consecutive-hour maximum operating limit per session with cool-down periods between sessions for larger volumes.
Does it work with an extension cord?
Using an extension cord with a 1500W appliance requires a heavy-duty cord rated for the current load. A minimum 14AWG extension cord rated for 15A or higher is required. Standard lightweight extension cords (16AWG or thinner) are not rated for 1500W continuous load and present a fire risk from cable overheating. If possible, position the container within the 32.5-inch cable reach of a wall outlet and avoid extension cords entirely. Never use a coiled extension cord at 1500W load — uncoil fully before use to prevent heat buildup in the coiled cable.
Is the voltage 127V or 120V? Will it work in the US?
127V AC is the rated operating voltage of this unit. Standard US household outlets deliver 120V AC nominal (typically 115–125V in practice). The 127V rating indicates the unit is designed for the 120–127V AC range found across North American and some Latin American markets — it will operate normally on US 120V household outlets. Do not attempt to use this unit on 220–240V outlets (used in most of Europe, the UK, Australia, and Asia) without a voltage converter — doing so will damage the unit and presents a serious electrical hazard.
How do I know when the water is at the right temperature?
The heater has no built-in thermostat or temperature indicator. Use a cooking or bath thermometer to measure water temperature. The correct procedure is: unplug the heater from the wall, wait 30 seconds, stir the water gently to equalize temperature throughout the container, then measure with the thermometer. Do not measure temperature while the heater is operating. For a warm bath, 98–104°F is the typical comfortable range. For a pool, 80–88°F is comfortable for swimming in warmer weather.
Can I leave it running and go to sleep or leave the room?
No — do not leave the heater operating unattended. The heater must be monitored during use. The 3-consecutive-hour maximum operating limit, the no-dry-run safety requirement, and the fire risk from cable degradation all require that the heater is operated only while a responsible adult is present and able to respond to any equipment issue. Unplug the heater before leaving the room or going to sleep. Do not use a timer switch to operate the heater unattended.
Exactly What I Needed for the Inflatable Pool. Heats Fast and Works Every Time.
“I bought this for an inflatable pool in the backyard that fills from the garden hose with cold water. In Phoenix in spring, the water is cold enough in the morning that the kids won’t get in without warming it first. This heater raises the pool temperature to comfortable in about 45 minutes from cold fill on a typical spring morning. I follow the safety instructions exactly — fully submerge first, plug in, monitor the whole time, unplug and remove before anyone gets in. The stainless element looks good after 15 uses and the cable shows no signs of heat stress. Does exactly what it says.”
“I use this for a Japanese-style wooden soaking barrel in the garden. The barrel holds about 30 gallons and I run two heating sessions of about 90 minutes each to get to soaking temperature. The stainless element handles the wooden barrel environment without any corrosion issues after six months of weekly use. The cable is long enough to reach from the outdoor outlet to the barrel without an extension cord. I read the safety warnings carefully before the first use and follow them every time — the sequence of submerge first, plug in, never touch the water while it’s running, unplug before removing is straightforward and has become automatic after a few sessions.”
“I travel for work and stay in extended-stay hotels and apartments where the hot water is consistently inadequate. The bathtub fills with water that goes lukewarm halfway through filling and I’m done with cold bath water. This heater fits in my toiletry bag alongside other gear and solves the problem completely. Fill the tub, put the heater in, plug in, wait about 20 minutes, unplug and remove, check temperature, get in. The compact size and the 32.5-inch cable handle every bathtub configuration I’ve encountered in 30-plus hotel stays. The only thing I’d add is a carrying case but at this price point I’m not complaining.”
