On-Demand Circulating Hot Water Pumps
Are you wasting good, treated, pumped from a well, while you wait for your shower to get hot? Do you have to run water in the kitchen to get hot water to the dishwasher? Are you committed to water conservation? Did you know that every home wastes thousands of gallons of water a year waiting for it to get hot?
Demand hot water circulation systems are not new. They have been around a long time, but recently with our current, and predictably constant water shortage, they could be a great contributor to water conservation. The concept is, that at the push of a button, water is pumped from the hot water line back into the cold-water line at the water fixture furthest from the water heater, usually a bathroom. A temperature sensor detects an increase in the water temperature as hot water arrives and shuts the pump off while you are getting ready for your shower. No water is wasted. The pump runs for less than a minute. Hot water is immediately available wherever the pump is installed, usually at the bathroom sink. Whether hot water is then available at other locations in your house depends on the plumbing layout. Ideally if there is only one main hot water line with small branches to the kitchen, bathrooms, and laundry, installing the pump at the end of the line should provide hot water within seconds anywhere in the house. (Remote buttons can be placed at other locations.) If the farthest point is at the end of one branch, say to the master bath, and the kitchen is at the end of another branch, this will affect the time it takes for hot water to reach the kitchen. A second pump would be required.
For tankless water heaters, the pump must have a high enough flow rate to activate the water heater. I would recommend at least 10 gallons/minute. For pipe runs of over 100’, you would need a bigger pump, over 20 gallons/minute.
These Demand systems are simple to install- you can get kits that provide the hardware you need. However, they do require an electrical outlet. In the case of a bathroom sink, on outlet can usually be added by extending wiring from an existing outlet by the sink. This is the only part of the installation that requires trade skills and incidentally, a permit. The “button” is actually a doorbell button and is low voltage. An optional remote receiver hooks right up to the unit so it can be turned on from anywhere in the house with a remote transmitter button. Read more at gothotwater.com
