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.
What to Look for in Hot Water Recirculation System
Hot Water Circulation products include circulators, pumps and accessories typically
used for the circulation of water for heat transfer in a wide range of residential and light
commercial applications. Water circulation products are available in a variety of
materials including bronze, brass, cast iron and stainless steel.
Some preferred features to look for in purchasing your hot water recirculation system:
- All brass and stainless steel construction for a long life.
- A long warranty of at least 6-years.
- Adjustable thermostatic control to reduce unnecessary energy usage.
- Easy installation (not requiring a water pump, pipe cutting, soldering or electrical
What Are Hot Water Recirculating Systems?
Recirculation Systems are often used to circulate domestic hot water so that a faucet
will provide hot water instantly upon demand. In regions where water conservation is
sues are rising in importance with rapidly expanding and urbanizing populations local wa
ter authorities offer rebates to homeowners and builders that install a hot water r
ecirculation system to save water. In typical one-way plumbing without a recirculation sy
stem, water is simply piped from the water heater through the pipes to the tap. Once
the tap is shut off, the water remaining in the pipes cools producing the familiar wait f
or hot water the next time the tap is opened. By adding a recirculation system and c
onstantly circulating a small amount of hot water through the pipes from the heater t
o the furthest fixture and back to the heater, the water in the pipes is always hot, and no
water is wasted during the wait. While the majority of these systems require a pump and
have no adjustable temperature capabilities, a significant reduction in energy can
be achieved by utilizing a temperature adjustable thermostatically controlled recircu
lation valve mounted at the last fixture on the loop. Thermostatically controlled valves
allow owners to choose the desired temperature of hot water to be maintained within t
he hot water pipes since most homes. Thermostatically controlled recircu
lation valves cycle on and off to maintain a user's chosen temperature and consu
me less energy than a continuously operating pump. By installing a thermostatically co
ntrolled valve just at the farthest fixture on the loop, convection circulated hot water rea
ches the entire loop. Installing a circulation pump on a hot water circulation loop can be
difficult due to limited available space, cosmetics, noise restrictions or lack of avail
able power. Recent advancements in hot water circulation technology used by the
Hot Water Lobster Instant Hot Water Valve allow for benefiting from temperature control
led hot water circulation without the need to install a pump. This advanced eco-friendly
hot water circulation system utilizes a temperature controlled valve strategically inst
alled at the last fixture on the loop. Thermal insulation applied to the pipes helps mitigate
this second loss and minimize the amount of water that must be circulated to keep hot
water constantly available.
The traditional hot water recirculation system uses a dedicated return line from the poin
t of use located farthest from the hot water tank back to the hot water tank. In home
s where this return line was not installed the cold water line is used as a return line. Red
uced energy waste and discomfort is possible by preventing occurrences of hot water
line siphoning in open-loop hot water circulation systems which utilize the cold wate
r line to return water back to the water heater. Hot Water Line Siphoning occurs whe
n water from within the hot water line siphons or is forced into the cold water line due
to differences in water pressure between the hot and cold water lines. Utilizing a tempe
rature controlled hot water recirculating valve significantly reduces energy consum
ption by preventing siphoning of hot water out of hot water lines during cold water use.
A temperature controlled hot water recirculating valve can also prevent pipe freeze.
Prevent Your Pipes From Freezing:
The best solution to preventing your pipes from freezing is to simply install innov
ative 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.
