CAMPLUX Electric Mini-Tank Water Heater 8 Gallon ME80B - Compact

In this review of the CAMPLUX Electric Mini-Tank Water Heater 8 Gallon (ME80B) the bottom line is simple: this is a compact, point-of-use heater built for kitchens, utility sinks and small RV or workshop needs where fast, local hot water matters most. The single biggest reason to buy is its space-saving design combined with an insulated 8 gallon tank that delivers on-demand hot water right at the sink, reducing wait time and energy loss compared with running water from a distant tank. It is presented as a straightforward, UL-listed plug-in solution that is easy to install and maintain.

Key Features

• Compact 8 gallon tank: Fits neatly under a sink or on a shelf to provide hot water right where it is needed without a full-size heater installation.
• Built-in insulation foam: Reduces standby heat loss so the unit holds temperature efficiently and helps save energy and money over time.
• Glass-lined tank: Improves durability and resistance to corrosion, making the heater easier to maintain and extending service life.
• Thermostat control with three settings: Lets users choose temperatures between about 50F and 149F for tasks from handwashing to dish prep.
• Versatile mounting and 120V plug-in: Can be wall, shelf, or floor mounted and plugs into a standard 120 volt outlet for simple installation under most sinks.
• Safety features included: UL approval, a CSA listed temperature and pressure relief valve, and a high limit overheat device provide multiple layers of protection.

Who It's For

This unit is best for homeowners, renters or RV owners who need hot water close to a sink without reworking a whole-house system; it excels as a point-of-use solution for kitchens, laundry sinks, garages, and small utility rooms. Installers and DIYers will appreciate the 120V plug-in design, 3/4" NPT water connections and included mount kit which keep installation straightforward.

It is not intended as a bathing heater or for high-flow whole-house needs; people who need sustained high-volume hot water for showers or multiple bathrooms should look at larger-capacity or dedicated tankless solutions designed for that purpose.
