The Insta-Hot package gives you instant hot water and the security of flood prevention. Includes a Waterstone Hot Tank, PRV (pressure regulator valve) and a Safety Valve Leak Detector unit in a single package. Hot Tank is designed with a integrated vent that works with any Waterstone Hot and Cold, or Hot Only Filtration faucets. The 1/2 gallon stainless steel tank dispenses steaming hot water instantly and is perfect for making hot coffee, tea, cooking or sink cleanup. An insulated, solder less, heating tank, the Waterstone Hot Tank has an adjustable temperature control that ranges from 140F to 190F (60C to 88C). 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.
