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 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
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
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 (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 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
water heater tank  and the Hot Water Lobster Instant Hot Water Valve.

      Easy Ways to Make Your Home More Energy Efficient

Your house is an eco-system. You save money and improve performance when you
take cost-effective measures that reduce energy use, and install systems and
appliances that are the right size to meet your needs. In general, the wrong size
systems and use more energy and increase operating costs.

The most effective strategy for improving household energy efficiency is to first target
your home’s envelope—walls, attic, windows, and doors. Then improve the energy
efficiency of systems, such as heating, cooling, lighting, and appliances. Finally,
consider clean energy generation (solar, geothermal, and so on).

1. Make sure your walls and attic are well insulated. Effective insulation slows the rate
that heat flows out of the house in winter or into the house in summer, so less energy is
required to heat or cool the house. If your house has no wall insulation, and it has
more-or-less continuous wall cavities (such as conventional stud walls), blown-in
insulation can greatly improve your comfort and save enough energy to be very cost-
effective. (It rarely pays to blow additional insulation into already insulated walls.) If your
attic is unfinished, it often pays to upgrade its insulation.

Your contractor’s expertise is more important than the insulation material you choose.
Properly installed fiberglass, cellulose, and most foam insulation materials can all
reduce the heat conduction of the completed wall system. The key is “properly
installed.” Ideally, the contractor will use an infrared camera during or after installation
to look for voids.

2. Upgrade or replace windows. If your windows are old and leaky, it may be time to
replace them with energy-efficient models or boost their efficiency with weatherstripping
and storm windows. It is almost never cost-effective to replace windows just to save
energy. According to, replacing windows will save 7 to 24 percent of
your heating and air-conditioning bills, but the larger savings would be associated with
replacing single-glazed windows. However, if you are replacing windows for other
reasons anyway, in many areas the additional cost of Energy Star–rated replacement
windows is very modest, perhaps $15 per window. This upgrade would be cost-
effective—and increase your comfort to boot.

3. Plant shade trees and shrubs around your house. If your house is older, with
relatively poor insulation and windows, good landscaping (particularly deciduous trees)
can save energy, especially if planted on the house’s west side. In summer, the foliage
blocks infrared radiation that would warm the house, while in winter the bare branches
let this radiation come through. Of course, if your house has very good insulation and
Energy Star or better windows, the effect is much, much smaller because the building
shell itself is already blocking almost all the heat gain.

4. Replace an older furnace with a high-efficiency system. If your furnace was built
before 1992 and has a standing pilot, it probably wastes 35 percent of the fuel it uses,
and it is probably near the end of its service life. In this case, in all but the warmest
climates, ACEEE recommends early replacement with a condensing furnace with
annual efficiency of at least 90 percent. This type of furnace wastes no more than 10
percent of the natural gas you buy, and may save you as much as 27 percent on your
heating bill.

If your furnace was installed after 1991, it probably has an annual fuel utilization
efficiency (AFUE) rating of 80 percent, so the savings from replacement is smaller, but
would be at least 11 percent if the unit is working perfectly. Your heating service
technician or energy auditor may be able to help you determine the AFUE of your
present system.

For houses with boilers and hot-water heat distribution (radiators, baseboard), the
savings from a modern condensing boiler with outdoor reset or equivalent feedback
controls can be substantially larger, since the condensing boilers allow reducing the
circulating loop temperature almost all the time.

5. Improve the efficiency of your hot water system. First, turn down the temperature of
your water heater to the warm setting (120°F). Second, insulate your hot water lines so
they don’t cool off as quickly between uses. Third, use low-flow fixtures for showers and
baths. While storage water heater standards were raised in 2001, it was probably not
enough to justify throwing out an existing water heater that is working well.

Savvy consumers are now installing eco-friendly hot water recirculation valves, which
provide instant hot water to your plumbing (so water is not wasted down the drain
waiting for water to run hot at your faucet or shower). The Hot Water Lobster Instant
Hot water Valve is a simple DIY installation (no water pump required) which can save an
average household up to 17,000 gallons per year. While providing faster hat water to
all you fixtures, it also saves energy costs and can prevent pipe freezing.

6. Replace incandescent lightbulbs with compact fluorescent lamps (CFLs) or LEDs.
CFLs can save three-quarters of the electricity used by incandescents. Most people
don’t think about the fact that the electricity to run a lightbulb costs much more than the
bulb itself. One of the new CFLs costs about two or three dollars, but it lasts 10,000
hours and uses only about 27 watts to generate as much light as a 100-watt
incandescent bulb. During its life, it uses about $22 in electricity, so the total cost is
about $25. A 100-watt incandescent bulb costs 50 cents, but lasts 1,000 hours so you
need 10 of them ($5 to buy) to last 10,000 hours. In those 10,000 hours you will use
1,000 kilowatts of electricity, which will cost more than $80 at a national average price.
So the lighting cost of the CFL is less than one-third of the cost for the incandescent.
The best targets for replacement are 60- to 100-watt bulbs used several hours a day,
because usage affects how long it takes to recover the investment.

7. If you buy a new refrigerator, don’t leave the old one plugged in. Avoid the
temptation to use the old fridge as a backup for party supplies and liquid refreshment.
The extra storage space will cost you: figure an extra $50–150 per year in electricity to
keep that older fridge running. In contrast, the new fridge, particularly if Energy Star
rated, may cost only $30–60 per year to run because refrigerator efficiency has
improved so much in the past three decades. Under these circumstances, think about
how much refrigeration you really need. The best rule is to have only one refrigerator,
and to size it to meet your real needs. That allows the luxury of ice-makers and similar
conveniences with a clear conscience.

Also consider configuration. A similarly sized refrigerator with a top-mount freezer will
use 20 to 25 percent less energy than a side-by-side model and often offers more
usable refrigerator and freezer space.

8. Take advantage of new tax incentives to improve your home. Federal tax incentives
are available through the American Recovery and Reinvestment Act of 2009. Energy
efficiency incentives for upgrades to existing homes have been extended, and are now
available for 2009 and 2010. These incentives now cover up to $1,500 (from $500),
based on 30 percent of the cost of the improvement. Improvements can include
building-envelope improvements (windows, insulation) and heating/air-conditioning
upgrades. There are also 30-percent credits, without a cap, for on-site renewables
(solar photovoltaic and solar hot-water systems, small wind systems, and geothermal
heat pumps).

9. Schedule an energy audit for more expert advice on your home as a whole.
Energy auditors and raters use specialized tools and skills to evaluate your home and
recommend the most cost-effective measures to improve its comfort and efficiency, as
well as the best sequence for doing them to take advantage of interactions. The rater
can also provide independent verification of contractors’ work quality. Look for raters
who are RESNET Accredited. In some regions, there are Home Performance with
Energy Star programs, too. Most of these programs include low-cost home assessment
and strong quality assurance practices and/or inspections.

10. Install a temperature controlled hot water recirculation valve, which provides instant
hot water (so water is not wasted down the drain waiting for water to run hot at your
faucet or shower). This simple eco friendly DIY installation (no water pump required)
can save an average household up to 17,000 gallons per year. It also saves energy

                   How To Prevent Pipes From Freezing

If you've ever had the misfortune of having a water pipe freeze and burst, you know
first hand about what a devastating impact it can have on your home. The broken pipe
itself is actually relatively minor, but the damage caused by the leaking water running
through your walls and ceiling can mean a major reconstruction project, requiring
replacing drywall, ceilings and maybe even furniture and appliances. Here are some
ways to make sure you never have to go through that hassle.

1. Plan ahead and figure out which pipes could potentially freeze. Water pipes running
through unheated crawl spaces and pipes running through walls to the outside are
prime candidates for freezing.

2. Turn off the water supply lines running to your outside taps before the cold weather
arrives. There is usually a shut off valve in the water supply line close to where it goes
through the outside wall. Once the water is shut off inside, go outside and open the
outside taps as well. This will drain any water remaining in the pipe or in the tap, so
there's nothing to freeze.

3. Check any pipes that run close to outside walls. Put some insulation between the
pipe and the wall to help keep the cold away from the pipe.

4. Insulate any pipes that run through unheated crawl spaces. Wrap them with
finsulation and tape or put preformed pipe sleeve insulation along the pipes, then tape
the sleeves in place.

5. Install electrical heating tape (available at home stores) on any pipes that run
through areas that get really cold, like garages.

6. OR, simply an innovative and patented technology known as a “temperature
controlled hot water recirculating valve” (it’s a breeze to install-no pipe cutting,
soldering or electrical connections). It uses your existing water pipes and the thermal
convection generated by your water heater to keep water circulating back to your water
heater for reheating (not requiring a pump or any electricity). Warm circulating water
will not freeze. 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.
