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.

What To Know About Hot Water Recirculation Systems​​



Water heating is the third largest energy expense in your home. It typically accounts for about 12% of your utility bill. There are four ways to cut your water heating bills: use less hot water, turn down the thermostat on your water heater, insulate your water heater, or buy a new, more efficient model.


Tips To Use Less Hot Water:

  • Install aerating and low-flow faucets and showerheads.
  • Install an eco-friendly thermal convection powered hot water recirculating system to your plumbing, has a temperature controlled by-pass valve and requires no electricity to operate. There is no water waste with this type of system, and it also minimizes energy waste since it only re-circulates when the hot water at your faucet cools below your desired temperature and can prevent pipe freezing.
  • Repair leaky faucets promptly a leaky faucet wastes gallons of water in a short period of time.
  • Lower the thermostat on your water heater water heaters sometimes come from the factory with high temperature settings, but a setting of 120°F provides comfortable hot water for most uses.
  • Insulate your electric hot-water storage tank, but be careful not to cover the thermostat. Follow the manufacturer's recommendations.
  • Insulate your natural gas or oil hot-water storage tank, but be careful not to cover the water heater's top, bottom, thermostat, or burner compartment. Follow the manufacturer's recommendations when in doubt, get professional help.
  • Insulate the first 6 feet of the hot and cold water pipes connected to the water heater.
  • If you are in the market for a new dishwasher or clothes washer, consider buying an efficient, water-saving model to reduce hot water use.
  • Drain a quart of water from your water tank every 3 months to remove sediment that impedes heat transfer and lowers the efficiency of your heater. The type of water tank you have determines the steps to take, so follow the manufacturer's advice.
  • Although most water heaters last 10–15 years, it's best to start shopping now for a new one if yours is more than 7 years old. Doing some research before your heater fails will enable you to select one that most appropriately meets your needs. Long-Term Savings Tips:
  • Buy a new energy-efficient water heater. While it may cost more initially than a standard water heater, the energy savings will continue during the lifetime of the appliance.
  • Look for efficient water heaters in the following categories: high efficiency gas non-condensing, gas condensing, electric heat pump, gas tankless, and solar.
  • Consider installing a drain water waste heat recovery system. A recent DOE study showed energy savings of 25% to about 30% for water heating using such a system.
  • Heat pump water heaters can be very cost-effective in some areas.
  • 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 eco-friendly DIY installation (no water pump required) and can save an average household up to 17,000 gallons per year. It also saves energy costs and can prevent pipe freezing. ​
