A chauffe-eau solaire individuel is a solar water heater designed to supply hot water to a home. The five products provided here are not solar water heaters: they are an immersion heater and propane tankless water heaters intended mainly for RVs. The LOQOMI is best suited to portable, small-volume heating, while the RV models are for mobile hot-water use. Use this comparison to assess those alternatives, but choose a solar thermal system if your priority is heating household water with energy from the sun.
| Product | Best suited for | Heating type |
|---|---|---|
| LOQOMI Immersion Heater | Portable small-volume heating | Electric |
| 55,000 BTU RV Tankless Heater | RV users seeking on-demand hot water | Propane |
| CAMPLUX 65,000 BTU RV Heater | RV use with a 2.64 GPM specification | Propane |
| 11Gen 65,000 BTU RV Heater | RV owners who need a 15-by-15-inch door | Propane |
| 65,000 BTU RV Heater With 18-Inch Door | RV installations requiring an 18-by-18-inch door | Propane |
LOQOMI Portable Immersion Water Heater
Best for: People who need to heat water in a bucket, small stock tank, or other suitable container rather than supply hot water to an entire home. The listing describes a 2,000-watt heater with a digital thermostat, automatic shutoff at 165°F, and a 304 stainless steel protective guard. It says the unit is intended for uses such as camping, pet bathing, and small pools.
This is the only product in the list described as a compact, portable electric heater. It may suit occasional tasks where a permanent water-heating system is unnecessary. It is not a solar device or a substitute for a household solar thermal tank.
Limitation: The instructions say to fully submerge it before plugging it into a 110V outlet and to keep it at least three feet from flammable materials. Its small-container use does not make it appropriate for whole-home hot water.
55,000 BTU RV Tankless Water Heater
Best for: RV or camper owners looking for an on-demand propane heater. The product name lists 55,000 BTU, a 2.9 GPM flow rate, 12V DC operation, and high-altitude use up to 9,800 feet. The listing also identifies it as CSA certified.
Choose this model over a solar household water heater only when the need is specifically an RV installation. Its stated flow rate is higher than the CAMPLUX model below, but that specification alone does not establish performance in every setup.
Limitation: It is a propane RV appliance, not a solar thermal system for a house. Check installation requirements and the listed specifications before choosing it.
CAMPLUX 65,000 BTU RV Tankless Heater
Best for: RV owners comparing propane tankless units who want the stated 65,000 BTU capacity and 2.64 GPM flow rate. The product name also identifies it as CSA certified. It is a more relevant choice than a portable immersion heater when the use case is an RV water-heating system.
Compare its flow-rate figure with the 2.9 GPM model above, while considering the actual RV setup and the product documentation. Neither model uses solar energy, so this is an alternative only for mobile hot-water needs.
Limitation: The supplied information does not specify installation dimensions or other operating details. Confirm those details with the manufacturer before purchase.
11Gen RV Heater With 15-Inch Door
Best for: RV owners whose installation calls for a 15-by-15-inch door. The listing describes a 65,000 BTU tankless propane water heater with 12V DC operation, high-altitude availability, and a showerhead. Those details distinguish it from models whose primary listed difference is another door size or flow rate.
Choose this unit if the stated dimensions and included showerhead match your RV requirements. The available product details do not establish that it fits a particular RV, so measure the opening and verify the installation instructions.
Limitation: This is an RV propane heater, not a solar-powered domestic water heater. Door dimensions must be checked against the actual installation opening.
65,000 BTU RV Heater With 18-Inch Door
Best for: RV installations that specifically require an 18-by-18-inch black door. The product name lists a 65,000 BTU capacity and 12V DC operation. Its clearest comparison point is the larger door dimension versus the 15-by-15-inch model above.
Before selecting it, compare the stated opening size with the RV’s measurements and review the full installation requirements. The listing information supplied does not include a flow-rate figure, so buyers should not assume it matches another model’s output.
Limitation: Its RV-focused propane format does not meet a household solar water-heating requirement.
Buying Guide: Choosing A Solar Water Heater Or Alternative
Do you need solar thermal hot water for a home?
Look for a complete solar water-heating system intended for residential use, not an RV heater or a portable immersion element. A typical solar thermal setup uses collectors to capture heat and a storage tank to hold hot water; system designs vary. Confirm that the product is specifically intended for household domestic hot water and that its capacity suits the people and fixtures in the home.
How should you compare household solar systems?
- Household demand: Consider daily hot-water use and storage capacity rather than choosing by collector size alone.
- Site conditions: Ask whether the roof or installation area has suitable sun exposure and structural support. Shade and orientation can affect solar collection.
- Climate and backup: Check how the system is designed to handle colder conditions and periods of low sunlight. Determine whether auxiliary heating is included or required.
- Installation: Confirm plumbing, permits, and local code requirements with a qualified installer. A solar thermal system is not automatically a simple do-it-yourself replacement.
When do these listed alternatives make sense?
The immersion heater is designed for portable, limited-volume tasks. The propane tankless products are presented as RV appliances, and their key distinctions include stated BTU capacity, flow rate, altitude information, and door dimensions. Compare the features that match your actual use; do not treat any of these as a solar water heater for an individual home.
