Features

  • 1500W IMMERSION HEATINGThis 1500W immersion water heater uses an upgraded magnesium oxide heating element for efficient heating. The open-slot protective guard helps improve water circulation for better heat transfer. Heats 5 gallons of water from 68F to 83F in about 8 minutes. Heating time may vary by water volume, starting temperature, and conditions.
  • DURABLE BUILD, STABLE CONNECTIONOur portable water heater is made with 316L stainless steel material, making it better suited than 304 stainless steel for repeated water immersion. It helps resist rust and corrosion, supporting a longer service life. The heater measures 11 in long and includes a 79 in power cord, providing 90 in total length when fully extended. The NEMA 5-15P plug improves outlet compatibility and helps provide a stable connection during use.
  • SAFE 5-STEP USEAdd enough clean water to keep the water level at least 2 in / 5 cm above the heater. Fully submerge the heating section before plugging in. Do not touch the heater or place hands in the water while heating. Use the thermometer to monitor water temperature and heating time. After use, unplug first and allow the heater to cool before removing it from the water.
  • DIGITAL TEMPERATURE MONITORThis immersion water heater includes a separate thermometer to help you check water temperature during heating. Simply place the probe into the water when using it in a bathtub, bucket, or small inflatable pool, so you can monitor the current temperature without guessing.
  • DEDICATED POWER FOR STABLE HEATINGEach heater must be plugged into a separate 120V / 15A or higher-rated outlet. Do not plug two heaters into the same outlet. Avoid using power strips or extension cords. If using multiple heaters, connect each one to its own dedicated outlet.

Description

Can it really heat bathtub water? Yes. The 1500W heating element, magnesium oxide heat-conducting structure, and open-slot guard help transfer heat into the water efficiently, so you can enjoy comfortably warm water faster. Can it handle repeated water use while keeping a stable connection? Yes. The 316L stainless steel metal heating body is specially designed to better resist rust and corrosion from repeated water use. The NEMA 5-15P plug fits standard U.S. outlets and helps maintain a stable power connection during heating. This is my first time using it—what should I watch out for? Use clean tap water only. Avoid seawater, well water, or corrosive liquids. Fully submerge the heater before plugging it in, and use a separate 120V / 15A or higher-rated outlet. After heating, unplug first and let it cool before removing it. How do I know if the water temperature is right? The heater includes a separate thermometer to help you check the water temperature during heating. Just place the probe in the water and monitor the temperature, making it easier to use in bathtubs, buckets, and small inflatable pools. How do I care for the heater so it lasts longer? Rinse the heating body with clean water, dry it thoroughly, and store it in a dry place. For scale buildup, use vinegar or a suitable descaler, then rinse and dry. Do not scrape with sharp tools or metal brushes, and avoid storing it wet.

  • Great product!!
Very pleased with it. Hests a 5 gallon bucket of water up pretty quickly!! There was a delay in shipping on behalf of Amazon, but it was functional upon arrival. Recommended! Price was comparable to others in this class of immersion heaters. Has a case surrounding the rod. It'll be extremely hot when you pull it out of the water. I hung mine up so it vould cool off without melting anything! I'd buy this again!! ... show more

I use this to heat up and maintain 50 gallons of water at 85° for my mobile dog grooming business. It does a great job ever at below zero temps.

  • Heavy-duty titanium with a clear safety plug and digital temp monitor
EMERGENCY UTILITY & MATERIAL BUILD: Having one of these immersion heaters in your household can be an absolute lifesaver and should be part of every home’s emergency survival or disaster preparedness kit. Whether your primary hot water heater blows, or the power goes out and you are running on a generator, needing hot water and being unable to heat it can become a critical safety issue. This specific unit features a longer-lasting, highly conductive titanium heating element over standard stainless steel, which naturally prevents rust and corrosion with repeated use. The inner heating element utilizes magnesium oxide to transfer heat efficiently, and the open-slot outer cage design allows for superior water circulation compared to basic models. According to the manufacturer, it can heat a standard 5-gallon bucket in about 8 minutes. CRITICAL SAFETY FEATURES & SETUP: The manufacturer is highly vigilant about safety compliance, which is a massive plus. The unit includes a clear, translucent NEMA 3-prong grounded plug, allowing you to visually inspect the internal wiring and connections before plugging it in. Because this heater draws a continuous 1500W of power until unplugged, knowing what is happening behind the scenes is crucial to prevent fire or shock. A CRITICAL SAFETY WARNING: Never touch or place your hands or any body parts into the water to check the temperature while the heater is plugged in and submersed. Doing so runs a severe risk of hospitalization or worse. Instead, use the included separate digital thermometer. It arrives with a battery ready to go—simply pull the clear plastic guard from the battery compartment to activate it. You submerse only the metal-tipped probe rod into the water to consistently monitor the temperature rise from a safe distance. TESTING OBSERVATIONS: For my test, I filled up a full bathtub high enough to completely submerse the heating element. Because my 100+ year old house lacks bathroom AC outlets, I had to rely on a heavy-duty extension cord to power it, which is generally not advised by the manufacturer. After leaving the unit running for about 20 to 30 minutes, the digital thermometer only indicated a rise of a few degrees, and the water still felt relatively cool to the touch. The power cord did not get hot, meaning it wasn't overtaxed or drawing improperly. The lack of intense heat was likely due to the massive volume of a full bathtub being too large for a single portable probe to heat quickly, combined with the extension cord setup. The probe did visibly bubble at the surface, indicating the element works perfectly. I look forward to testing it again in a smaller, more appropriate 5-gallon vessel. The watertight construction is excellent, and no liquid leaked into the internal wiring. One minor quirk is that the digital thermometer lacks a physical off button or switch. Even after leaving it out to dry for several days, the display remained on. To avoid wasting the battery, I recommend removing the cell between uses and storing it in a small baggie taped to the unit. PROS: >> High-quality titanium construction prevents rust and ensures longevity over steel models. >> Translucent visual safety plug allows for easy wiring inspection before drawing high power. >> Efficient magnesium oxide heating element with an open cage for optimal water flow. >> Includes a dedicated full-color user manual with extensive safety procedures. >> Comes with a bonus submersible digital thermometer and an ash-style liquid transfer scoop. CONS: >> Thermometer lacks an on/off switch, requiring manual battery removal to preserve power. >> Not designed to heat massive open vessels like full bathtubs efficiently in short windows. BOTTOM LINE: Overall, this is an incredibly well-made, safety-conscious emergency tool that works exactly as intended when paired with the right-sized container. It is awesome to have on hand for unexpected power outages or plumbing failures, and I highly recommend it as a staple addition to any household survival kit or off-grid gear collection. ... show more

  • Hefty Immersion Water Heater.
This water heater seems to be thought very well. In a separate small bag you will find the digital thermometer which has an external wired temperature probe, to monitor the temperature of the water. The thermometer comes with the batteries installed and a plastic tab to prevent battery draining. In most devices, you pull the tab to make the device work. In this thermometer, you have to open the battery compartment, remove the batteries, remove the plastic tab, reinsert the batteries. If you try to just pull the tab, it will not come out. The heater comes in a sealed bag It has a plastic cage to prevent contact with the heater element itself, and avoid burns to the body and to the container in which it is used. The immersion heater measures 35mm in diameter and 245mm long, not including the cable strain relief. The power cord is 79" long. I noticed that the power cable strain relief rotates freely with respect to the cable. I hope it is not an indication that water will leak into the electrical connections. The plug has a removable plastic protector for the prongs. The plug is molded in clear plastic and it includes a neon light to indicate that power is present. The power cord also has a label indicating that the heater element should be fully immersed in the water. The label has the FCC logo... why? Is there any radio frequency generation inside the immersion heater? hmmm.... The metallic heater element itself is marked as follows: 1500W 120V Titanium 202411 DURING USE THE HEATER MUST BE COMPLETELY SUBMERGED IN WATER OTHER USE WILL DAMAGE BY DRY BURNING Because it is an electrical heater, it is of the utmost importance that the outlet and the extension cord used, if any, have the proper grounding both at the receptacle as in the plug ends. The extension cord should be capable of handling 15 amps continuously. Keep in mind that conventional wall outlets with grounding prong are rated for 15 amps, so no other device connected to the same outlet should be used at the same time. The instructions indicate that it should not be used in metal containers. The instructions also indicate that neither the container or water should be touched when the heater element is energized and submerged in the water, and that the heater must be unplugged and allowed to cool down before removing from the water. The instructions recommend the use of a thermometer to determine the heating time (what??) and water temperature. In any case this immersion heater does its job and does it well; I do like it. Only time will tell how long it lasts. ... show more

  • Powerful Heating for Buckets & Small Pools - Solid Titanium Build
As a Vine reviewer, I’ve tested a few different immersion heaters over the years—mostly for heating water for outdoor cleaning or warming up a small inflatable soaking tub. This 1500W Titanium model stands out for a few specific reasons, but there are some safety protocols you definitely need to follow. Build Quality & Material The standout feature here is the Titanium element. Most budget heaters use stainless steel, which can eventually corrode or "pit" if you have hard water or use it frequently. Titanium is much more resistant to mineral buildup and chemical corrosion. The guard around the element is sturdy enough to prevent the heating coil from touching the bottom of your plastic bucket, which is essential to avoid a literal meltdown. Performance At 1500W, this pulls about 12.5 Amps. On a standard 15-amp household circuit, this means you cannot run anything else (like a vacuum or a hair dryer) on the same circuit without tripping a breaker. The Test: I used this to heat a 5-gallon bucket of cold tap water (approx. 55°F). It brought the water to a steaming 110°F in about 12–15 minutes. Small Pools: If you’re trying to heat a 200-gallon "stock tank" pool, be realistic—this will take several hours to see a significant temp rise. It’s best suited for 5–20 gallon applications. Safety (Read This!) This is a high-draw appliance. The NEMA 5-15P plug is a standard three-prong grounded plug. Water Level: You must ensure the heating element is fully submerged before plugging it in. If you run it "dry," it will burn out the fuse (or the element) in seconds. Stay Out of the Water: Do not put your hands in the water while this is plugged in. Even with the grounded plug, it’s best practice to unplug it before testing the temperature with your hand. GFCI is a Must: Only use this with a GFCI-protected outlet (the ones with the "test/reset" buttons). Since you’re mixing 1500W of electricity with water, you want that extra layer of protection. Pros: Titanium Element: Better longevity than stainless steel. Heavy Duty Cord: The cable doesn't get excessively hot during a 20-minute run. Fast Heating: Maxes out the power available from a standard US wall outlet. ... show more
