About water+
The water+® system is a step in a new direction for an energy system that can change the way we heat and cool our homes and businesses to dramatically reduce energy costs and protect the environment.

What is water+?
Just below the surface of nearly every urban and suburban home, commercial building, institution or school lies an abundant source of clean, renewable, and free energy. The revolutionary water+ system, transports this thermal energy stored in the earth to homes and buildings via a water utility main to provide the finest in heating and cooling comfort with low operating costs.

How does it work?
Instead of using conventional geothermal earth loops, the utility’s water main acts as the heat source and heat sink for geothermal units. Water from the main is supplied to the geothermal heat pump(s) located within the building. Using this source, the geothermal units—which are up four times more efficient than conventional heating and cooling systems—provide total heating and cooling comfort throughout the building at a fraction of the cost of ordinary HVAC systems.

After passing through the geothermal unit(s), the water is returned to the water+ line and transported to the processing plant, existing substation or a station built for this purpose. There it is tested and returned to the final stage of treatment before being pumped back out into the main. Water passing through the system is altered in no way except for a slight temperature change as it passes through the unit. As the water returns to the treatment plant or substation, the earth surrounding the line absorbs the difference in temperature, thus the water becomes a 100% renewable source of energy.

Increased revenue and bigger savings.
The water utility charges the building owner a flat fee (monthly or yearly) or a fee per each 1000 gallons of water used by the system. The fee covers the pumping costs, treatment costs and profit for the utility. The profit for this service is normally not regulated, so it can be a great source of income for the utility while providing a very welcome advantage to the building owner. The building owner also pays the cost of the water+ line either outright or through a monthly charge.

The savings to the building owner are massive. The system operates at 16-20 EER versus 9-10 EER for conventional heating and cooling. It also eliminates the need for roof penetrations, cooling towers, boilers, expensive interior piping (associated with 4-pipe systems) and associated maintenance. The equipment is less costly and has an average life expectancy of over 20 years versus 12 years for conventional outdoor units, according to reports issued by the Air Conditioning Refrigeration Institute (ARI).
