SAVE WATER! At ONLY $179.95, the eco-friendly Hot Water Lobster Instant Hot Water Valve provides faster hot water which saves water, saves energy and saves time. 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 the cold ground temperature.

HOW IT WORKS! When the water in your pipes 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 water pipes and back to your hot water tank for reheating. Your hot water tank now uses less energy by reheating the warm water instead of cold ground temperature water. When hot water 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 water down the drain! Installing the Hot Water Lobster instant hot water control valve at the fixture furthest from your hot water tank (as shown in the installation diagram) will provide faster hot water to all of the fixtures in your house.


NO ELECTRICITY NECESSARY! 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.


MORE HOT WATER! Adds as much as 10% more capacity to your current hot water system (by keeping the water stored in your hot water pipes hot!).


KEEP PIPES FROM FREEZING! The Hot Water Lobster instant hot water valve automatically allows water in your pipes to circulate when the control valve cools below the set temperature (even if your electricity goes out). Circulating water is less likely to freeze (especially when the water is warm).


REDUCES CONDENSATION! The Hot Water Lobster instant hot water valve reduces condensation on pipes and toilets basins.


MAINTENANCE FREE! The Hot Water Lobster has a solid brass valve body with an adjustable thermal controlled stainless steel valve stem enclosed in a mounting box.


EASY INSTALLATION! The Hot Water Lobster comes complete with the mounting box, 4 sets of 12" flexible water lines with standard brass fittings. All pre-assembled and tested for an easy 10-minute installation.


STATISTICS! *A typical family wastes approximately 12,000-17,000 gallons of water annually waiting for warm water to reach the tap. *as determined by GAMA (Gas Appliance Manufactures Association).


Note: Circulation of water by thermal convection must not be restricted (no check-valves) between the water heater tank and the Hot Water Lobster Instant Hot Water Valve.

Lets Evaluate Hot Water Recirculation Systems


Metlund's product, uses your existing water pipes and requires the pump and valve to operate together under the sink (which creates a secondary requirement for electricity under the sink where there is not usually an outlet) and is difficult to install. In addition, it requires the user to activate it to call for water - in residential applications this will typically be a pushbutton. Unfortunately, the consumer must first push the start button to cycle the water (which is often not near the fixture desiring hot water…dishwasher, washing machine, 2nd bathroom and etc.). The pump life is estimated at only 2-years. Laing's product uses a similar concept - creating a recirculation loop using existing hot and cold water pipes and a pump.


Laing's pump turns on automatically whenever the hot water cools below a pre-set, non-adjustable temperature. The pump is also located under the sink (which creates the requirement for electricity under the sink where there is not usually an outlet) and is difficult to install. When operating, the pump completely fills the cold water lines with hot water, limiting the ability for the consumer to prevent scalding by adjusting the final water temperatures (mixing cold water to the hot water). The pump life is also estimated at only 2-years.


Grundfos’ product also uses a similar concept, using your existing water lines, a bypass valve and pump (located at your water heater) with a timer to control water flow. The bypass valve has a pre-set, non-adjustable temperature setting (which also doesn't allow the consumer to adjust the temperature to meet specific needs). Grundfos’ product will not provide instant hot water other than when the pump is running and is difficult to install (requiring electrical connections and pipe cutting and soldering at your water heater). When operating, the pump completely fills the cold water lines with hot water, limiting the ability for the consumer to prevent scalding by adjusting the final water temperatures (mixing cold water to the hot water). The pump life is also estimated at only 2-years.


The Hot Water Lobster Instant Hot Water Valve uses an eco-friendly innovative and patented method of hot water recirculation. It uses your existing water pipes and the thermal convection generated by your water heater to circulate the water back to your water heater for reheating (not requiring a water pump or any electricity). This automatic recirculation can also prevent pipe freezing. This system has a temperature-controlled valve that allows the consumer to easily adjust the temperature control knob to meet their particular needs. There is no water waste with this type of system, and it also minimizes energy waste since it only re-circulates water when the hot water at your faucet cools below your desired temperature. Installation is a simple D.I.Y., 15-minute project (not requiring a water pump, any pipe cutting, soldering or electrical connections). The Hot Water Lobster Instant Hot Water Valve also has a 10-year warranty.
