Nisus - Model CHW -Constant Hot Water Module

Works with all water heaters and most on-demand hot water circulation systems.

The CHW keeps water pipes hot so that when you want hot water it will be available in a few seconds, not minutes.

By monitoring the temperature of the water in the Bridge Valve, our technology can provide hot water in a matter of seconds.

First you need an on-demand circulation system like those found on this website. The CHW can also be used with other on-demand brands as well.

Every 15 minutes the electronics of the CHW activates the circulation pump. If the water in the Bridge Valve has cooled below 95℉ the pump will push hot water out into your house. The Bridge Valve will then close and the pump will shut off.

If the water in the Bridge Valve is above 95℉ the pump will immediately turn off.

The CHW doesn`t need to run 24 hours a day - only during times when hot water will be needed. For instance, the CHW does not need to run between 11:00 pm at night and 6:00 am in the morning.

The CHW can be plugged into a standard wall timer form any home improvement store that has the ability to select zone when it is on or off.
