We had a hot water dispenser that quit working after 10 years. I ordered a different unit and it turned out to be the same as a hot water heater, not good. After putting up with this second unit for 2 years, I started looking for a different unit. I found this unit and now we have peace in the house again. My wife has instant coffee, we sit our 1 year old grandson and now she can make her hot coffee and warm up his food and everyone is happy!! I would recommend this unit to everyone who wants or needs instant hot water, no waiting..
