A leading kitchen writer has outlined benefits of swapping a hot water pot or kettle for an on-demand hot water tap in the kitchen.Writing for the Daily Herald, James Dulley says that keeping a pot of water hot all day can be a triple loss, resulting in higher electricity consumption, less efficient air conditioning and increased humidity in the home.Dulley writes A sink-mounted hot water dispenser is a much more efficient method to get hot water instantly for tea or coffee. There also are many other uses for the instant hot water, such as warming baby food, cleaning cheese or butter off a knife, etc.The expert goes on to explain how such a device can be useful in preparing meals When steaming rice or boiling vegetables on the stove, it is safe to start with heated water from the dispenser. This will save energy overall.Dulley also recommends one of the top on-demand hot water taps on the market from leading manufacturer In-Sink-Erator.
