Why customers choose TaskHolt Tools

Meet KENUOS’ 2.5 gallon under-sink instant hot water heater. With a 1500-watt element and 120V supply, it delivers reliable warm water when you need it most. The compact mini tank fits under the sink and is designed to provide hot water quickly without a lengthy wait.

The tank uses a reinforced 0.04" wall thickness for longevity and features an LED temperature display so you can monitor real-time heat. A safety T&P valve guards against excessive pressure and temperature, while the 3-way valve lets water flow to two sinks, adding convenience for kitchens, RVs, or mobile setups.

Fast, efficient heating

Thanks to an upgraded L-shaped heating tube, the heater expands the heating area and reaches hot water in about 4–6 minutes. That means less time waiting and more time enjoying warm water when you need it.

Smart control and insulation

Adjust the temperature anywhere between 86°F and 149°F with the user-friendly knob. An integrated temperature control chip powers a heat-preservation mode when the target range is reached, while non-toxic polyurethane foam insulation extends water retention for longer use between fills.

Safe, durable, and easy to install

Constructed with an ABS shell and a stainless-steel tank, this unit withstands daily use while resisting corrosion. It’s UL-certified and offers overheating protection. Included accessories cover 1/2" NPT fittings, T&P valve, 3-way diverter, and necessary pipes for quick setup.
