SpiroFlo: Residential Applications

Tired of high energy costs and waiting for hot water at your shower in winter?

 

Learn below about how installing SpiroFlo in your home delivers hot water to your shower 35% faster while using less water and less electricity. Unlike tankless or recirculating water heaters, one SpiroFlo device  is a complete house system. These findings were qualified through a grant through the Colorado Governor's Energy Office.

 

SpiroFlo: Allowing homeowners to go green while improving their routine.


Residential Comparison

 

Everyone has a morning routine, but for some households, this routine involves gallons of water going down the drain while waiting for the shower to get hot. Though it may seem like mere minutes per day, within this time frame, trillions upon trillions of gallons of water go down the drain unused each year. This water still ends up at a wastewater facility, thereby increasing both a household‘s water and wastewater bill and the state’s treatment costs. The cost of reheating the replaced water also adds to a household‘s carbon footprint and energy bill. At a time where several counties in a naturally dry states are draining the aquifers faster than they’re being replenished, this kind of waste is no longer optional.

 

With this in mind, SpiroFlo believes it’s time for water to be treated like the valuable commodity it is.

 

SpiroFlo was awarded an Innovative Funding for Energy Efficiency (IFEE) grant from the Colorado Governor’s Energy Office. With this grant, SpiroFlo tested its water- and energy-saving device in homes around the Denver Metro area. During the trial, participants recorded their wait time for hot water at the designated outlet for 5-7 days both before and after the installation of the SpiroFlo device.

 

This IFEE study concluded that the patented SpiroFlo device allows for a faster shower for most homeowners (4 out of 5), all while conserving water, electricity and providing green benefits on day one. The average wait time for hot water in positive installs went down from 62.41 seconds to 40.77 seconds—a 34.82% reduction. In addition to the wait time benefits, there is also water volume savings of up to 5% at every hot water outlet in the house. With the combined benefits in wait time and volume savings, a four-person household can conserve an average of 3,869 gallons a year (as well as the energy savings from not having to heat/reheat water). Using these average numbers as the standard, if only 20% of Colorado housing units had a SpiroFlo device installed, this could translate into saving nearly 1.68 billion gallons annually. If every housing unit in the U.S. had a SpiroFlo device, the total amount of water conserved in a year would be over 500 billion gallons.

 

There are also anecdotal benefits from the SpiroFlo device. These include getting hotter water (confirmed in 40% of trial households), less energy being used to re-heat the water, higher water pressure and softer skin (this benefit was confirmed by a hydrologist). One SpiroFlo installed at the outlet of a hot water tank is a complete system for the whole house. There is no need for the costly modifications and ventilation requirements associated with tankless and recirculating devices. Savvy DIY homeowners are able to install the SpiroFlo device themselves and several plumbers expressed interest in absorbing the cost of the SpiroFlo device within their standard installation costs.
