We had it installed by professioal. I think that was a good choice and would be a recommendation. We love this. My husband drinks chi tea all day and i, coffee. We had blown thru a couple of kurig s and did not want to sink anymore $$ into that. This was the perfect decision. The water is always hot and instantly available as advertised. We have the heat set at half way and get steaming hot water. I would recommend to anyone. It's great.
