How much hot water can I save?
Tests show that a 2000 square foot house could save up to 16,000 gallons per year.

"I have multiple hot water branches. If I use the UP15-10S  series, how will I get water to all branches?"
You can order additional comfort valves for each branch.

 How much power does the pump use?

The pump is rated for 24 watts (equivalent to a small light bulb).

 Does the pump need to be located at the hot water heater?

The pump can be located anywhere in the loop.  The easiest location is at the water heater.  The pump has a 3/4" fitting that is a standard connection for water heaters.

How far in advance of needing hot water should I set the timer?

Set the timer so the pump comes on 15-30 minutes prior to your need for hot water.

Could I still have locations in my house where the hot water side is still cold?

It is possible to have multiple runs for pipe from your hot water heater.  This is easily addressed by adding additional valves for these locations.  (The Pump kit includes one valve.  Additional valves may be purchased with no additional freight charges.)

Must the valve be in a horizontal position for it to work properly?

No.  It can be in any position.

How can I tell if the pump is running?

The pump is very quiet.  If you are getting hot water in accordance with your timer settings, the pump is running.

Will the valve work with other pumps?

No.  The valve is designed to work exclusively with the Grundfos Comfort Pump.  The use of any other pump will over pump or under pump the system, causing the system to fail and void the warranty.
