Did you know? Water = Energy

In California "water-related energy use consumes 19 percent of the state's electricity, 30 percent of its natural gas, and 88 BILLION gallons of diesel fuel every year - and this demand is growing."

Courtesy California Energy Commission Report CEC-700-2005-011-SF.

When you save water — even cold water — you’re helping to saving energy and reduce carbon emissions too!

The bottom line: Metlund vs. Laing

The Metlund demand system is the most efficient in terms of energy use; and it always provides freshly heated water - but it takes a few seconds (still way faster than running the tap though). On the other hand, Laing automatic systems always have hot water at the ready and require no change in user behavior - however the water may be warmer or hotter depending on how recently the system performed a flush, and energy is not used as efficiently

easy installation

benefits:
• the convenience of near-instant hot water throughout the house
• saves thousands of gallons of water annually in the average household
• pays for itself quickly through water, sewer, and energy savings
• installation takes two hours or less - no major plumbing required and in most cases, one system serves all taps
• silent and maintenance-free
• works with almost any water heating system (same models even work with tankless water heaters )
• helps dish and clothes washers work more efficiently and extends water heater life

limitations
• not strictly "instant", Laing systems provide shower warm water immediately, with full-hot water a few moments later; Metlund systems require a button press (or motion sensor) to deliver full hot water 5 times faster than running the tap
• larger homes with more than one plumbing line require multiple units

Save Water, Energy & Time with an Instant Hot Water System

Economical, easy-to-install recirculation systems from Metlund and Laing are smart conservation devices — and you’ll never wait for hot water again!

Long waits for hot water are more than just irritating - they cost money and waste water and energy. The average family can easily run 10,000 gallons or more down the drain every year. There's a simple and inexpensive way to solve this problem in your existing home or avoid it in your new home: an instant hot water system.

These ingenious little devices provide:

	•	the convenience of nearly instant hot water throughout the house
	•	substantial water and energy savings year over year
	•	easy installation with most existing plumbing systems
	•	silent, maintenance-free operation

We love these systems because they're win-win-win — they deliver great convenience, and make both environmental and economic sense at the same time. And all with a low-cost, easy-install little device. You can't beat that combination.

All models feature:

• one pump serves all taps
on a single plumbing run

• near-instant hot water at
the push of a button (or motion-sensor activation)

• max water/energy savings

• consistent delivery temp

• silent operation

• largest model suitable
for tankless systems

• five-year warranty (S-50
has a 3 year warranty)

MORE ABOUT INSTANT HOT WATER

How instant hot water systems work

The problem of course is that water heated by your water heater sits in the line between the heater and the tap(s) where it cools off. Let's call this "previously hot" water. When you turn on the tap you need to flush out this previously hot water to get to the fresh hot stuff. With low-flow faucets and long plumbing runs, this can take a long time - and waste a lot of water. And it can cause problems for your appliances too - forcing washers and dishwashers to use more time and energy heating their own water (or worse, run with water not hot enough to clean). An instant hot water system - or hot water recirculation system - flushes the previously hot water back into the hot water tank (rather than you running it down the drain) so you have freshly heated water waiting for you when you turn on the faucet - instant hot water. Most instant hot water systems use the same basic approach - a special pump flushes previously hot water from the hot water line, sending it back to the heater through the cold water line.

Differences between systems

Differences lie in how the systems are activated and how fast they work. The Laing AutoCirc1 performs a flush whenever it senses the water temperature has fallen below a certain level; the Metland D'MAND systems are, as the name implies, "on demand" - a high-speed flush is triggered by either button or motion sensor. With the Metlund and Laing AutoCirc1 systems, the pump installs at the most remote fixture (at the end of the plumbing run).

How much do instant hot water systems save?

Water savings for a household of four occupants varies from about 900 gallons to about 3000 gallons per point of use, per year (DOE study). Point of use is a single location at a home, for example a faucet where hot water is available. The water savings in a home with four points of use, on the average, would be 3,600 to 12,000 gallons per year. So, conservatively, if your home saved only 20 gallons of water each day (7,300 gallons per year) then in one year you could save between $100 and $200, considering water, energy and sewage charges.

Usage considerations

Once installed, these systems are quiet, dependable and maintenance-free. Laing provides a 2 year warranty on their units (from the manufacture date or 1 year from the purchase date, whichever is greater) while Metlund provides a 5-year warranty. The Metlund systems are activated by users and so household members need to adapt their habits a bit (basically you just learn to hit the button as you walk into the bathroom).

Physical placement

The pump units are located at the last fixture on your plumbing run (for example under a sink). If you are not sure of the layout of your plumbing, try following the pipes from the heater if that is possible - or call a professional plumber.

Plumbing requirements

These systems work with most typical residential plumbing configurations. However, there are a few considerations. First, if you have a tankless hot water heater, you must go with the largest Metlund system, the S-02. This is the only system that can work fast enough to keep up with your tankless heater. Second, if you have determined that your home has more than one plumbing run (a branched system) you will required multiple units (one for each branch).

Electrical requirements

All Laing and Metlund units units are low-wattage pumps that plug into standard 115v outlets.
