InSinkErator is one of the pioneers in designing and manufacturing food waste disposers and instant hot water dispensers for home and commercial use. The company was founded in 1927, when the world's first food waste disposer was built, in Racine, Wisconsin, where the company's headquarters is based today.


What is great with an InSinkErator hot water dispenser, is that it produces hot and warm water instantly for your convenience. It usually comes as an all-in-one system and can be installed easily in the existing or new kitchen, and used for many applications, from comfortable hand washing to preparing the food and cleaning dishes.

InSinkErator uses a small tank and filtration system installed under the sink to heat and filter domestic water.

Another great benefit of having the InSinkErator instant hot water dispenser is the availability of fresh and clean hot water for use at any time. Mounted at the point-of-use service, a dispenser saves you energy and water, especially for small jobs, so a large 40 and 50-gallon heater or tankless unit, which supplies the whole house, doesn't have to run when a small amount of water is needed.


An InSinkErator hot water dispenser is available in different styles and finishes with the low and high arching spouts, swivel and non-swivel, and with one, two-lever and twist handles.

Some of the InSinkErator models (i.e., Involve H-Wave) dispenses hot water only, while others are designed to dispense both cold and hot water (i.e., Involve HC-Wave). InSinkErator water dispensers can produce temperatures near boiling - 200 F, except models from the UltraSystem series. Models UW and UWL from UltraSystem series blend 200 F water from the tank and cold from supply to provide 110 F, which is great for handwashing, shaving, and general clean-up.

InSinkErator uses tanks that deliver on-demand flow and are compatible with all dispensers made by this company. Tanks are made from stainless steel for longer life and have tool-less connectors and dry start protection for safety. There is a temperature dial at the front of the tank that allows you to adjust the temperature that suits your needs the best.

The maximum temperature it can provide is 200 F. With the capacity of 2/3 of a gallon, the tank offers a maximum of 60 cups per hour. Model Hot1 is the only model that can use a smaller tank; it has a capacity of 1/3 of a gallon and provides a maximum of 40 cups per hour.


If you don't have a filtration system, it is recommended to get a filter F-201 that is compatible with any InSinkErator hot water dispenser. These filters are designed to reduce chlorine taste and odor, lead, mercury, and other chemicals, and they can be used with ice makers and refrigerators.
