- 2.7-gallon capacity fits under sinks with dimensions of 13.8 x 10.8 x 10.8 inches.
- Adjustable thermostat ranges from 86°F to 167°F via a front rotary knob.
- Glass-lined tank and V0-grade foam insulation for durability and efficiency.

Who it fits
Good fit for
You should consider this unit if you need hot water for a single sink in a kitchen, bathroom, office, or RV. The 2.7-gallon tank is ideal for light tasks like hand washing or dish rinsing. Its compact size allows installation in tight cabinets where larger heaters cannot go. The 120V connection works with standard household outlets, making it easy to integrate into existing plumbing. If you want consistent, warm water without waiting for a central heater, this small tank delivers on demand.
Who should skip it
Skip this model if you require high-volume hot water for showers or multiple fixtures. The 2.7-gallon capacity will run out quickly during extended use. You also need a dedicated 120V circuit near the sink, as the included cord is only 3.28 feet long. If you live in a cold climate, note that the recovery rate may struggle to keep up with rapid demand. This heater is not designed to supply whole-house hot water or handle heavy commercial use.
Verdict: This mini-tank is a practical solution for single-sink hot water needs in tight spaces. Its specs support efficient, safe operation for light daily use.
Key specs explained for this unit
Capacity: 2.7 gallons
This small volume holds just enough hot water for one sink. It suits single users or quick handwashing. It is not for showers or tubs. When comparing to tankless water heaters, note that tankless units provide endless hot water. This mini-tank stores a limited supply. You must wait for it to refill and reheat after heavy use. It fits under sinks where space is tight.
Wattage: 1440 W
This power rating determines how fast the water heats. At 1440 watts, it provides a steady recovery rate for point-of-use tasks. It is lower than whole-house tankless heaters, which often draw 30,000 watts or more. This lower draw makes it safe for standard 120-volt outlets. You do not need a dedicated high-amperage circuit. It is ideal for offices or RVs with limited electrical capacity.
Temperature Control: 86°F to 167°F
The rotary knob lets you set the exact water temperature. The range covers warm water for dishes up to hot water for sanitizing. Higher settings help kill bacteria in the tank. When shopping for tankless water heaters, check their max temperature. Many reach 140°F. This unit goes higher, offering flexibility for different household needs. Adjust the knob to balance energy use and hygiene.
Dimensions: 13.8 x 10.8 x 10.8 inches
These measurements define the physical footprint of the heater. It is compact enough to fit under most standard kitchen or bathroom sinks. The height is slightly over a foot, so check your cabinet clearance. Tankless water heaters are often mounted on walls and have different dimensions. This unit sits on the floor of the cabinet. Measure your available space before buying to ensure a proper fit.
Design and Build Quality
The BN-LINK 2.7 Gal Electric Mini-Tank features a white plastic shell with a glass-lined interior. According to the listing, this combination offers thermal insulation and resistance to corrosion. The external casing is made of plastic, which keeps the unit lightweight. The total weight is 14.5 pounds. This low mass makes it easy to handle during installation under a sink or in a cabinet. The compact dimensions are 13.8 by 10.8 by 10.8 inches. Its small footprint allows it to fit in tight spaces where larger water heaters cannot go. The design prioritizes space efficiency for kitchens, bathrooms, offices, or RVs.
The control layout is simple and practical. A front-mounted rotary knob adjusts the water temperature. You can set the output between 86°F and 167°F. This range covers most household needs for handwashing or dishwashing. The unit includes dry combustion and overheat protection for safety. These features are built into the electrical system to prevent damage if the tank runs empty. The power cord is 3.28 feet long, allowing flexible placement near an outlet. The finish is a standard white plastic, which blends into most under-sink environments. The ETL certification indicates it meets safety standards for electrical components. The glass-lined tank is designed to protect against rust and leakage over time. This construction supports its role as a durable point-of-use heater for single sinks.
Setup and Daily Operation Guide
Installation begins with ensuring you have a standard 120-volt outlet nearby. The unit includes a 3.28-foot power cord, so you may need an extension if the sink is far from a wall socket. The BN-LINK CP-C190 is designed to fit under sinks, in cabinets, or in compact spaces like RVs. Its dimensions are 13.8 by 10.8 by 10.8 inches, and it weighs 14.5 pounds. This small footprint allows it to sit securely on a shelf or mount to a wall, depending on your preference.
Before turning on the power, you must fill the 2.7-gallon tank completely with water. The listing warns that operating the heater without water can cause damage. Once filled, you can plug it in. The front-mounted rotary knob lets you adjust the temperature between 86°F and 167°F. You can set it to a lower temperature for handwashing or higher for dishes. The unit features dry combustion and overheat protection, which shut off the heating element if the water gets too hot or if the tank runs dry.
In daily use, the 1440-watt heating element provides a recovery rate of 6.8 gallons per hour at a 90°F rise. This means the tank replenishes hot water quickly after you use it. You can use this heater independently for one sink or install it in series with a larger system to supply multiple sinks. The V0-grade flame-retardant foam insulation helps maintain water temperature while reducing energy consumption. Always ensure the tank remains full to protect the glass-lined interior from corrosion and rust.
Before You Buy This Mini-Tank
You should verify your outlet matches the 120-volt requirement before installation. The unit includes a short power cord, so you may need an extension if your sink is far from a wall socket. Ensure the tank is completely filled with water before powering on to prevent damage. This heater works best as a point-of-use solution for a single sink. It complements larger tankless systems by supplying hot water to remote fixtures. Unlike whole-home tankless water heaters, this small unit does not serve showers. Check that your cabinet has enough space for the 13.8-inch height. You must also confirm that the 1440-watt draw does not exceed your circuit capacity. Regularly check the glass-lined tank for any signs of leakage. This compact heater fits well in tight spaces like RVs or offices where space is limited.
Check before you buy
- Confirm you have a standard 120-volt outlet nearby.
- Measure cabinet space to fit the 13.8-inch height.
- Ensure the tank is full before turning it on.
- Check if the 1440-watt load fits your circuit.
