Hot Water Lobster

The Hot Water Lobster Instant hot Water Valve incorporates the flexibility of an adjustable temperature control with quality materials and workmanship for a long maintenance-free life and easy installation (not requiring electrical wiring, timers or perishable pumps). It even has a 30-day unconditional money back guarantee, as well as a 10-year parts and labor warranty.
When the hot water cools at the Hot Water Lobster Valve, the valve slowly opens allowing the cooler water to cross through the valve to the cold-water side of the plumbing. The thermal convection to the bottom of the hot water tank, while it forces the hotter water (from the hot water tank) into the hot water pipes.
When the hot water reaches the valve, the valve slowly closes and stops the crossover flow of water. The cycle repeats when the valve cools below the adjustable temperature setting.
Takes almost 1 1/2gal. water running at my kitchen faucet before it gets hot. Seem's this device would certainly correct that. I have new Hot Water heater..don't think it has any check valves to hamper operation of water circulating.
