Customer Review: “OMG, I love this hot water dispenser. Great for making teas, hot cereals and instant coffee in half the time because the water is already hot and waiting to be used. As a bonus, it disinfects and cleans dishes and bottles with out chemicals because the temperature of the water is 160-210° F.I choose this model because I installed a 3 stage water filtration system under the sink and i wanted only one additional spout added to the top of the sink.”
Customer Review: “If you already have the needed power and 3/8 cold water connection this is nearly a snap to install. But I needed to add an outlet under the sink as the disposal and dishwasher were directly wired from a junction box. Added outlet with disposal on one and dishwasher circuit on the other. Keeping the dishwasher directly wired it gave me a plugin for the tank unit.”

Whether I’m preparing tea, warming baby bottles, or quickly rinsing dishes, this system handles it all with ease.One thing to note is that while the system is filter-compatible, the water filter itself was a separate purchase. However, it was easy to install and has worked seamlessly with the dispenser, ensuring great-tasting water every time.”

I like this one best because it provides instant hot water, and it also can dispense filtered cold water eliminating the nasty chlorine taste.

Customer Reviews
Customer Review: “This is the third instant-hot hot/cool water dispenser combo I’ve installed in my kitchen. The first two were ISE/Insinkerator brand products that failed after 7 years or so when the boiler started to leak. No other plumbing item in my home has as short a lifetime as those ISE instant-hot water systems, so this time I went looking for a different brand.At $210 for the faucet/boiler combo, better than a third less than the cheapest ISE brand alternative, I was a little worried this system would look cheap. I am delightfully surprised. If anything it makes the ISE combos look shoddy.”
Customer Review: “This ReadyHot Hot and Cold Dispenser seems to work very well, looks good and was a straight forward installation/retrofit for the existing unit. I already had the water supply T and shut of valve, as well as an inline water filter from a previous hot/cold installation. The electrical outlet was already under my sink for the garbage disposer unit, so nothing to do for the electrical.”
