Inspired as we are to harmonize with nature by creating as much solar electric energy our homes need annually, we also come to understand the impact of our water use.  We realize too much water runs down the drain as we wait for warm water.

A simple tactic homeowners can take is to not allow water to pass down the drain while waiting for hot water.  Many people are placing buckets, or other containers in the flow until warm temperature is at hand.  While commendable, many just don’t have the patience and/or motivation to perform such a duty.  Another tactic would be to use the stopper at the sink allowing the cold water to accumulate until enough hot water has warmed it up for use.  But, this too has it’s limitations.

Priming with Hot Water D’MAND

The good news is that there’s a pump that can be retrofitted strategically to prime the majority of the hot water line with hot water.  It’s manufactured by ACT and is called Hot Water D’MAND Kontrols Systems.  They offer many options for water conservation for both residential and commercial buildings.

One of the first things we did during our remodel was to install this recirc pump at the kitchen sink for our hot water.  The kitchen’s hot water line runs past the bathrooms.  So, those lines would be primed with hot water at the main line, delivering hot water to the bathrooms with very little cold water left in the branch lines.  In larger homes additional pumps may be required to attain efficiency.

The pump works by forcing the cold water in the hot water line into the cold water line by use of a clever plumbing fitting.  That’s right.  The pump is powerful enough to force the water into the cold water line until it reaches a temperature of 72°, then automatically shuts off.

While Laundry to Landscape can be done by most homeowners using simple tools, we felt this gadget may require a plumber for a proper connection.  But, for those of you more confident in your capabilities, here’s a link to a video of an installation:  https://www.youtube.com/watch?v=4NYW0_X5Zbk
