TACO ISSUES NEW FLYER ON ITS D'MAND HOT WATER RECIRCULATION SYSTEM

- Flyer Emphasizes Benefits of Using D¡¦Mand System with
Tankless Water Heaters -

Cranston, RI, December 6, 2006 - Taco, Inc. has issued a new flyer on its D'Mand System and its use with tankless water heaters.

The flyer - Taco D'Mand Systems & Tankless Water Heaters -emphasizes the energy savings to be had with an on-demand water recirculation system like D'Mand and the fact that tankless water heater manufacturers are requiring use of such a system with their products to preserve full warranty coverage.

Some tankless water heater manufacturers have stated that the warranty coverage period for their products may be reduced if their products are used with a conventional timer-controlled recirculation system. Conventional water recirculation systems fitted with temperature sensors and timers are not considered "on demand."

Taco's D'Mand System delivers instant hot water by push button or motion sensing - not by temperature sensor or a timer. With on demand hot water recirculation provided by the D'Mand System, there are no standby or stack losses, and no need for extra storage tanks.

Tacos's D'Mand System should be installed between the hot and cold water line at the most distant hot water location; the unit fits easily under a conventional sink. D'Mand comes in three models and can be installed in single and multi-family homes as well as in commercial and institutional buildings.

D'Mand pumping systems are Green Spec Listed and qualify for EPA Energy Star water heating credits.

D'mand > recirc

I've had mine for two years and love it. No return line, no pipe insulation.

One issue that may come up: If you push the button but don't shower for another 20 minutes, then you'll have to wait. For this reason I guess I wouldn't recommend the motion sensor. Even if you had pipe insulation, then the problem would occur after, say, one hour.

BTW, how could timed recirc possibly affect a warranty? It just kicks on the heater once more per day than the actual users.
