Instant Hot Water Valve
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
HOW IT WORKS! 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 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 (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 (in 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 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 when
your electricity goes out).
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 mechanical 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 and standard brass fitting. All pre-assembled and tested for an easy 10-minute
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
hot water 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
Prevent Your Pipes From Freezing:
The best solution to preventing your pipes from freezing is to simply install innovative
and patented technology known as a “temperature controlled hot water recirculating
valve” (is a breeze-no pipe cutting, soldering or electrical connections). 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 pump or any
electricity). These systems are temperature-controlled and are easily adjustable to
meet your particular temperature needs. There is no water waste and it also reduces
the energy required to heat your water while it provides instant hot water to your
faucets and showers. A trickle of water circulating in your pipes will keep your pipes
from freezing in most circumstances.
