We are (thankfully) towards the end of a kitchen upgrade. Up to now there has been an electric Rheem 25L underbench hot water cylinder supplying the kitchen sink. The remainder of the house is on a gas infinity system and due to the layout there would be an unacceptably longish lag time before hot water would reach the kitchen sink.
The 25L Rheem cylinder is probably 10-12 years old although it appears to be working just fine. I'm thinking that it is probably towards the end of it's working life and should be replaced now that we are getting a plumber in.
Is this a sensible thing to do at this point? And does anyone have experience with small instant / tankless electric hot water systems that would be a suitable alternative?
Thanks in advance.
