DR Infrared Heater DR-988A
This model is designed for shop and garage heating where 240V circuits are available. The unit requires a dedicated 240-volt connection and delivers up to 5600 watts for high-heat output suitable for medium-sized enclosed spaces. It ships with a NEMA 6-30P power cord and requires a matching NEMA 6-30R receptacle. The listing emphasizes the need for a proper 240V outlet and appropriate wiring to support the specified current load.
Key features include a robust electrical design for continuous operation, and the specification that 240V is required for proper performance. This type is appropriate when fixed wiring or a 30A 240V receptacle is already present, and when you need a portable heater that can be moved but still demands a high-power supply.
DR Infrared Salamander 10000W
The DR-PS11024 Salamander is a high-capacity portable fan-forced electric heater designed for construction or large work areas. It operates on 240V single-phase and provides up to 10,000 watts of heat, intended for heavy-duty temporary space heating. The unit requires a 55-amp circuit breaker and heavy-gauge wiring consistent with its power draw.

Physical features include a heavy-duty steel frame and safety guards on intake and output ends for jobsite durability. This model suits environments that need rapid, odor-free heat where a high-capacity 240V supply is available. Users should plan for appropriate electrical infrastructure and confirm breaker and cord compatibility before deployment.
JUPSDDTH 3500W Pool Heater
This product is a 240V submersible pool immersion heater designed for heating large above-ground pools, inflatable pools, tubs, and baptismal fonts. It provides 3500 watts (≈11,942 BTU/h) and is specified for use with 240V power systems. The heater is rated for saltwater compatibility and uses a 316L stainless steel heating rod for improved corrosion resistance.
Electrical safety features include a CFCI (leakage detection) plug that cuts power rapidly in fault conditions and a 3M high-temperature cable with UL-certified insulation. The listing emphasizes fast installation without tools and professional grounding requirements for metal containers. This type suits pool owners who can supply a 240V dedicated circuit and need a portable heating solution that submerges directly in water.
JNICEANTAI 3500W Immersion Heater
This all-in-one immersion heater is built for portable water heating tasks including small pools, bathtubs, and stock tanks. It operates on 240V with 3500W output and includes integral GFCI and overload protection with an auto-reset function. The element uses 316 stainless steel for corrosion resistance and higher thermal efficiency.

Notable safety details are continuous GFCI monitoring and a leakage cutoff in 0.03 seconds, designed to reduce shock risk. The compact 19.7″ form factor makes it practical for tight spaces. The listing highlights professional grounding for metal containers and multi-purpose use where 240V is available for water heating needs rather than air space heating.
JNICEANTAI 3000W Pool & Hot Tub Heater
This 240V immersion heater offers 3000 watts for portable hot tub and small pool heating. The unit includes a GFCI plug and thermostat, with continuous protection and auto-reset features. Construction uses seamless 316L stainless steel to resist salt and chlorine corrosion and to improve longevity compared to lower-grade materials.
The product is positioned for quick installation in pools, tubs, and baptistries and stresses the same grounding precautions as other high-power submersible heaters. It is an option where slightly lower wattage than a 3500W unit is sufficient and where thermostatic control is desired to manage target water temperature.
Buying Guide: How To Choose A 240V Portable Heater
Selecting the right 240V portable heater depends on application, electrical capacity, portability needs, and safety features. Below are key considerations organized to help match a heater to your use case.
1. Define The Intended Use
Space heating (garages, workshops) and water heating (pools, tubs, baptistries) require very different designs. Fan-forced or infrared space heaters are for air warming. Submersible immersion heaters are for heating water and must be sold and used as such.
2. Confirm Electrical Supply And Circuit Capacity
240V heaters draw significant current. Check your breaker rating and available receptacles. Examples: the DR-988A requires a NEMA 6-30R (30A) receptacle while large units like the Salamander may require a 55A breaker. Installations often require a dedicated circuit and proper gauge wiring.
3. Match Power (Wattage) To Volume Or Area
For spaces, higher wattage yields faster temperature rise but needs proper wiring. For water, 3000–3500W units are common for small to medium pools or tubs. Calculate required BTU or kW based on the volume of water or cubic feet of space to be heated and the desired temperature rise.
4. Safety Features And Certifications
Look for GFCI or CFCI protection on water heaters and immersion devices. For air heaters, check for safety guards, thermal cutoffs, tip-over protection (if applicable), and UL or equivalent certifications. For submersible devices, auto-cutoff on faults and corrosion-resistant construction (316L stainless steel) are important.
5. Portability Versus Permanence
Some 240V heaters are portable but heavy and need robust cords and receptacles. Decide whether you need a truly portable unit you can repeatedly plug into different locations, or a semi-permanent installation with fixed wiring and a dedicated breaker.
6. Environmental And Material Compatibility
For pool and spa use, choose heaters made of 316L stainless steel for chlorine and saltwater resistance. For shop heaters, look for durable housings and protective guards for jobsite durability and easier maintenance.
7. Installation And Grounding Requirements
Many 240V devices require professional grounding and adherence to local electrical code. For metal containers or pools, professional grounding is often mandatory. Always verify local code and consider hiring a licensed electrician for 240V circuit work.
8. Controls And Thermostats
Thermostatic control is valuable for water heaters to maintain target temperature. For space heaters, adjustable heat settings or thermostats help reduce energy use and maintain comfort. Check whether the unit includes manual controls or requires an external controller.
9. Safety Use Practices
- Never bypass GFCI/CFCI protections.
- Follow manufacturer grounding and installation recommendations.
- Keep space heaters clear of combustibles and maintain distance from wet areas unless specifically rated for such use.
- Verify cord and plug types before plugging into a receptacle—do not force incompatible plugs.
10. Comparison Perspectives
Compare units by these dimensions: purpose (air vs. water), wattage and required amperage, plug/receptacle compatibility, safety features, and material durability. For workshops, prioritize robust fan heaters with compatible 240V wiring. For pools, prioritize corrosion resistance and fast-acting GFCI protection.
Using these considerations will help you narrow choices between heavy-duty fan-forced 240V heaters for spaces and immersion-style 240V heaters for water applications. Always match the device type to the task and the available electrical infrastructure.
