5 Best Instant Hot Water Dispensers

What is a hot water dispenser?

Instant hot water dispensers allow you to have hot water instantly.  This two part system has a small a spout that sits next to your kitchen faucet and a hot water tank that is positioned under the kitchen sink. The tank has a temperature dial that can be adjusted to your needs.

How difficult is it to install?

Installation should take between 2-4 hours. Most are pretty easy to install.  I think the InSinkErator seems to be the easiest to install. I like their instruction manual, installation videos and most people seem to be happy with their customer service.

Things to Consider

Check the maximum allowable counter thickness on your dispenser model. A measurement from the spout to the wall will be needed to know if handles can be used fully. Make sure you have a grounded outlet under the sink. And there should be enough room under sink for the tank to sit. This may be an issue if you have a filtration device already there.

Safety Features and Safety Concerns

Use a grounded outlet only. Do not store any flammables or towels under the sink when using a hot water dispenser system.

InSinkErator Invite H-HOT100 – Best reverse osmosis filter system for easy install

Yes, this is the third InSinkErator hot water dispenser that I am reviewing.  They have so many options that its difficult to choose just one of their models to write about.

This, more affordable, model has a push button instead of a lever.  It’s not quite as sleek but it comes with the same ⅔ gallon stainless steel tank and 5 easy step installation. The warranty is shorter, only a 1 year warranty for this model.
