We have a Westbrass Instant Water Chiller:

We have both an instant hot and the chiller under our sink and used a faucet that allows us to get both instant hot and instant cold water.

I love the chiller. I use it every day for the dog's water bowl and to make lemonade. DH uses it all the time for water too. It is kind of loud right after it's use but so worth having!

Thanks! I had seen the westbrass but could not find any reviews anywhere. Is it an instant chiller, or does it have a tank of chilled water?

Another thing to consider is a bottled water cooler or a bottleless water cooler that is plumbed directly into your water supply line. We use a small countertop water cooler at home. ItâÂÂs pretty slick, sits on the counter under the upper cabinet. My wife loves it for the instant hot water. I use it to try to keep on top of my water consumption since my Doc wants me to increase it.
