The Hot Water Lobster instant hot water valve is easy to install, affordable, and provides numerous benefits to making your home more environmentally-friendly.


When the water in your hot water pipe and the Hot Water Lobster control valve cools below the user adjustable temperature (77-140 F. degrees), the thermal materials within the Hot Water Lobster control valve contract and silently open the valve. Thermal convection within your hot water tank (differential of pressure between the top of the tank and the bottom of the tank) naturally circulates the cooled water through your existing cold water pipes and back to the hot water tank for reheating. Your existing hot water tank now uses less energy reheating the warm water instead of cold ground temperature water.

When fresh hot water enters your hot water pipe and reaches the Hot Water Lobster control valve, the valve automatically closes. This maintains hot water at the control valve without wasting water or wasting energy. Turn on your faucet or shower; and you get instant hot water instead of wasting it down the drain! Installing the Hot Water Lobster instant hot water control valve at the fixture furthest from your hot water tank will provide faster hot water to all of the fixtures in your house.


The Hot Water Lobster is all mechanical and designed to provide an electricity free solution to maintain hot water at the tap. This makes installation a snap (less than 10 minutes). Other hot water solutions require the use of electricity and pumps that make installation difficult and the pumps are often noisy and wear out in 2-4 years.
