"We installed SinkLye under our downstairs cloakroom basin in Bristol where we previously had no hot water pipe. It heats up instantly the second you open the tap. Very compact, neat, and the LED readout looks smart."

"Our kitchen tap in London is on the opposite side of the house from our boiler. We used to run the water for ages. With SinkLye under the sink, hot water is immediate at 45°C. Saved so much water already!"
