Hot Water Circulation SYSTEM EFFICIENCIES

PRICE-BASED ENGINEERED Comfort Valve Hot Water Circulators

According to nearly 100 professionals attending the 2006 Southern California Plumbing Heating Cooling Contractors trade show homeowners experience excessively high monthly gas bills and long waits for cold water with thermostatic valve circulation systems.  A closer examination reveals the costly inefficiencies inherent with these systems.  Comfort valve hot water circulators use a pump installed on top the water heater connected to the hot water supply pipe.  These heater mounted pumps have narrower connection fittings then the water heaters actual pipe reducing flow capacity or simultaneous hot water loads the water heater can fulfill.  Thermostatic comfort valves / sensor valves install under the sink to connect the homes hot and cold water lines together.  Materials within these valves expand / contract (open / close the valve) depending on the waters temperature contacting the valve..  These "normally open" valves close when 95F degree water is contacting the valve.  Anytime less than 95F degree water is not contacting the valve, the valve returns to it's normally open position.  Using cold water drops the pressure in the cold water lines but not the hot water lines.  The higher pressure in the hot water line forces water to siphon through the open valve and into the cold water line even though your intent is to only use cold water i.e. toilet flushing, watering lawn etc.  Until 95F degree water reaches the valve causing it to close the homeowner is left waiting for sometime before they actually receive water exclusively from their cold water line.  Thus, repeatedly adding significant additional demand on your water heater needlessly when using cold water.  By design, these system pumps must run continuously (continuous energy consumption) to prevent the "normally-open" thermostatic valve from opening.

PASSIVE "Normally Open" THERMOSTATIC COMFORT VALVE

Thermostatic comfort valves permit water siphoning from the hot water line into the cold water line during any cold water use by the homeowner when valve is in it's normally-open state.  Resulting in needless repeated demand being placed on the home hot water heater as well as making homeowners wait long periods before receiving water exclusively from their cold water line.

Comfort Valve in Default "Normally-Open" Position

Using any cold water causes crossover siphoning to occur due to pressure DROP in cold water line.

Cold water users must wait until 95F degree water from water heater closes valve before receiving water exclusively from cold water line

CONSERVATION-BASED ENGINEERED HOT WATER CIRCULATOR

For over a decade RedyTemp continues to be the industries "homeowner-preferred" hot water circulator due to the noticeably superior comfort and control it provides.  Strict engineering with a primary focus on efficiency, owner comfort and convenience while refusing to cut any corners which would sacrifice a consumers quality of life.  RedyTemp circulators incorporate tomorrows technology today, eliminating numerous inefficiencies found in other hot water circulators. 

RedyTemp is engineered with two separate flow controlling devices to prevent costly hot water line siphoning.  Utilizing a calcium proof / hard water friendly check valve and a stainless steel "normally closed" solenoid valve the RedyTemp prevents inefficient water siphoning from the hot water line to the cold water line.   Thereby, eliminating the discomfort and energy waste that occurs with thermostatic crossover valves and one-way check valves.  Water in the hot water line stays in the hot water line, minimizing demand on the water heater while maintaining greater cold water comfort.  Energy minded professionals and homeowners appreciate RedyTemp's temperature-based cyclic pumping operations increasing pump and water heater lifecycle while reducing energy consumption.

EFFICIENCY-BASED vs. PRICE-BASED ENGINEERED HOT WATER CIRCULATORS

Hot Water Circulator Performance, Savings and Comfort

*when less than 94F water leaves crossover valves open                 

A GREENER HOT WATER CIRCULATOR SYSTEM

• No long waits for hot water AND cold water comfort

• Only as needed should crossover occur

• Crossover flow controlled / no hot water line siphoning during cold water usage

• Owner selectable activating control type best matching their lifestyle (timer, motion sensor, push-button)

• Minimal pump operations through temperature based cyclic pumping reduces electrical consumption

• Provides off-scheduled convenience via single-cycle / on-demand operations

• Adjustable comfort temperature to optimize comfort and minimize water waste

• Receives temperature values from "water contacting" temperature sensor rather then a less accurate pipe clamp-on sensor

• Insulate hot water pipes to minimize heat loss

• Simplify installation to do-it-yourself level of complexity to save labor costs

• Optimize system settings to maximize performance and comfort

• No maintenance requirements (Calcium proof components to prevent calcium buildup, clog failures)

• Zone-Control capability using addition RedyTemps (guest rooms, occupied zones, etc.)
