Default Under sink recirculation systems

I have a customer that has a tankless and wants a under counter recirculation pump. I have been a devoted grundfos installer but the closest the get to under the counter are their comfort systems, but the pump mounts on the water heater and are controlled with a timer.... installing that on a tankless would kill it...

I have no idea what tankless he has yet.

The question is which manufacture has the beret better under sink system ?

why not use a Taco, these systems work well for me

D'MAND® System

Product > Water Circulation Pumps & Circulators > Wet Rotor Circulators > D'MAND® System


The Taco D’MAND System is the only recirculating system that operates 24 hours to provide hot water “on demand” at the same time it saves water, energy and money.

The D’MAND System is a small, silent pump that you attach to the hot and cold water lines in the cabinet under the most remote kitchen or bath fixture in the home. When the D’MAND System is activated, the cool water you normally let run down the drain is recirculated back to the water heater through the cold water line.

On demand, the pump circulates hot water from the water heater and returns the cooled water back through the cold water line. When the hot water arrives at the faucet, the D’MAND System’s patented heat sensor and control board shut off the pump to prevent pumping excess hot water into the cold water line.

  • Runs Only When Activated by the User
  • Automatically Senses When Water is Hot Enough.
  • Saves Water, Energy and Money
  • Saves Construction Costs—No new return line needed and no need to drain the system.
  • Simple Installation

The problem is, the Comfort System will not work with a tankless system, whereas the Taco D'Mand system will.

I used to only like the go grundfos comfort system, but thru the years of installing them, it's always been a challenge to set the timer for retired people with their habits. It also it's hard with large families that use water at odd changing times each day. With this type of system you should not have it running 24/7 or the cold side will warm up...

The push button system has been great, since my first post I've now installed about 10 and all customers have been praising them.

Might want to mention to the customer the increase in their utility expenses as well.

A retro fitted system won't have any insulated lines.
