The Insta-Hot package gives you instant hot water and the security of flood prevention. This system now includes the Waterstone Digital Hot Tank and a Safety Valve Leak Detector unit in a single package. The Digital Hot Tank has precision temperature adjustment from 167F to 208F as well as a digital interface and temperature control, providing the perfect hot water experience. Kitchen flooding often happens without warning and can cause substantial flooding and property damage if nobody is around to stop it. Waterstone’s Safety Valve Leak Detection Units are ideal for minimizing water damage when these disasters occur. Our Leak Detector automatically shuts off the water source when it detects moisture. Once the valve shuts off, the unit sounds off with an audible alarm, like a smoke detector, to let you know of a problem.
