SAVE WATER! The Hot Water Lobster Instant Hot Water Valve saves, water, time and money. How Long does it take for hot water to get to your faucet or shower? A lot of precious water is wasted down the drain while waiting for hot water. Even worse is the cost to heat the cold replacement water, which enters your house at ground temperature. HOW IT WORKS! When the water in your hot water pipe and the Hot Water Lobster control valve cools below the user adjustable temperature (40-149 degrees F), the thermal materials within the Hot Water Lobster control valve contract, and silently open the valve.

This video was shot on a cold Florida Day. 46F. The water was 56F. and reached a source temperature of 135F. After the 2 feet drop and outdoor leaching the collecting temperature was 97F. The purpose of this video is to illustrate how a fine mist can create some instant steam and hot water. If the flow was .25 of this, solid steam would result. Too fine of a stream and the Leidenfrost Effect would prevent proper absorption. I will do a video illustrating the effect soon. This is an alternative idea for more efficient steam production. You gain the small SPI of the hose and flash steam volume. This would need to be modified to do that. Video on that soon too I hope:-)

It says it is a 750watts unit.

Instant water heaters are among the most used appliances in typical households. They are needed to provide the hot water many people use for showering, dish washing, and washing clothes. An instant water heater is basically a small electric hot water tank or storage unit but is not gas fired. This small tank holds the hot water ready for use until you turn on the instant hot water tap in the sink.

The water is supplied to the tank through a small water line that runs off the sink’s main cold water feed line. It goes directly into the base of the tank where it is heated by some electric elements. This heating process causes the water to expand, so the water moves up into a holding tank on the top of the tank where it is kept hot. And once you turn on the tap, the hot water flows out, and fresh cold water flows into the bottom of the tank.

The capacity of an instant water dispenser varies, but usually ranges from 1/3 to 1/2 gallon; while the wattage of the heating elements usually range from 500 to 1500 Watts. And since the instant water heater tank produces water that is substantially hotter compared to the regular water heater tank, the water it delivers is delivered at a much slower rate compared to the water delivery speed of the regular tank.
