CAMPLUX Mini Tank Electric Water Heater 1.3 Gal - Compact Under-Sink

In this review of the CAMPLUX Mini Tank Electric Water Heater 1.3 Gallons, the bottom line is clear: this small point-of-use unit is best for homeowners or renters who need immediate hot water at a single sink and who value compact size and simple installation. The reviewer found the unit delivers on-demand hot water quickly, fits neatly under a sink, and offers a reassuring set of safety and longevity features such as a glass-lined tank and overheat protection, making it a practical choice for kitchens, utility sinks, or small bathrooms.

Key Features

• Compact footprint: With external dimensions near 11.4 in by 11.4 in by 9.7 in, it tucks under a sink or mounts on a wall without taking up much space.
• Fast hot water: The 1.3 gallon tank supplies immediate hot water at a sink so users do not wait through long pipe runs for warm water.
• Adjustable temperature: Three temperature settings cover a practical range from 68F to 140F so you can tailor output to washing or hand-washing needs.
• Built for safety: Automatic shutoff triggers if water temperature exceeds 203F, reducing risk of overheating and improving household safety.
• Durable construction: A UL listed unit with a glass-lined tank and insulation aims to extend service life and reduce corrosion risks.
• Simple hookup: Standard 1/2 inch NPT water connections and a 35.43 in cord mean typical under-sink installs take little time for anyone comfortable with basic plumbing.

Who It's For

This heater is ideal for homeowners, renters, or RV owners who need a dedicated hot water source for a single point of use such as a kitchen or laundry sink, or a small bathroom where the main water heater is far away. Installers who want a compact, plug-in style unit with basic temperature control and built-in safety will appreciate its straightforward setup.

It is less suitable for whole-house use or larger families that require continuous high-volume hot water; those shoppers should look at larger capacity or tankless systems designed for multiple fixtures. Also, anyone who needs hardline installations without a plug should verify electrical compatibility before purchasing.

Pros & Cons

Pros

Cons

• Small 1.3 gallon capacity limits continuous hot flow for extended tasks.
• Some customers have reported occasional leakage, so careful installation and inspection are recommended.
