"Always in hot water!"
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.

                           How to Save Water At Home
                                              (not listed in any order)

  • Don't flush the toilet every time you use it - as the saying goes: "If it's yellow let it
    mellow; if it's brown flush it down".
  • Install a dual-flush toilet - then if necessary you can use a short flush for urine
    and a longer flush for the rest.
  • Put a suitable container in your toilet cistern - this could be a brick or plastic
    container or so-called hippo and it will restrict the amount of water used with
    each flush.
  • Turn off the tap when you brush your teeth - a running tap uses more water than
  • Take a shower instead of a bath - a conventional shower (as opposed to a
    power shower) uses around two-thirds less water than a bath.
  • Don't use more water than you need to boil the kettle - if you're only making one
    or two cups of tea/coffee, you simply don't need to fill the kettle.
  • Keep a jug of water in the fridge - then, when you want really cold water, you
    don't have to run the tap to get it.
  • Don't run taps to rinse washing up - again this uses more water than you need
    for the task.
  • Use cold, waste water to wash out jars for recycling - it does the job just as well.
  • Only use the washing machine with a full load - even half-load cycles use more
    than half the water of a full load.
  • Only use the dishwasher with a full load - if you have to buy more dishes and
    utensils, then do it.
  • Never leave a tap dripping - if it needs a new washer, fix it.
  • Don't use a garden sprinkler - it uses far too much water.
  • Use plants that can withstand drought - Mediterranean species like lavenders,
    rosemary and cactus can survive with little water.
  • Don't overreact to a brown lawn - it will come back with rain in the autumn.
  • Use 'grey' water on the garden - this is old bath and washing up water (a
    reasonable amount of detergent will be no problem).
  • Collect rain water - this is most easily done with the installation of a rain butt.
  • Consider rainwater 'harvesting' - this is the posh version of a water butt and
    consists of a large tank that collects rain from the house guttering and pumps it
    into the home to be used for flushing the toilet.
  • Wash the car with a sponge and bucket - a hosepipe uses far too much water.
  • Consider installing a water meter - then you'll only pay for the water you actually
    use and having a precise measure will encourage you to monitor your water
  • Report burst pipes immediately to the local water company - then make sure the
    burst is fixed as soon as possible.
  • 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). The Hot Water Lobster Instant Hot Water Valve is
    a simple DIY installation (no water pump required) and can save an average
    household up to 17,000 gallons per year. Adding this eco-friendly hot water
    recirculating system to your plumbing not only provides faster hot water, it also
    saves energy costs and can prevent pipe freezing.

                      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.
