The EDC Process

Site Survey

Once EDC has been contacted, the process begins with a facility review. In this initial step the boilers and water heaters at your community or facility are evaluated to confirm that your Domestic Hot Water system is a candidate for EDC Controls.

Step 1 involves a visual overview of the physical hot water environment including:

• verification that the boilers are of proper size
• verification that the heater systems have recirculating loop pumps
• identification of boiler components, such as storage tanks, solar systems and other components
• Copies of 1-2 utility bills including account numbers and meter numbers. Optimally we would like the last 12 months gas utility bills

Installation

The EDC installation process does not alter your plumbing environment; rather an EDC technician installs the EDC Control(s) to the environment that is currently in place. This process involves installing a digital control, various temperature sensors, a relay connection to operate in series with your existing heater control circuit and a proprietary communication network to facilitate the monitoring of your systems data.

All of your existing temperature settings will remain unchanged. Because the EDC system is non-intrusive, it can be completely bypassed with a touch of a button switching you back to operation exactly as you were prior to installation.

Monitoring and Verification

Once the physical installation has taken place, EDC Technologies begins the process of remotely monitoring your facility for operational efficiency and potential issue identification. As an EDC client you can go online and view your environment at will. Online, our program allows you to track ongoing energy savings, view numerous operational reports, identify potential system issues along with suggestions for issue resolution.

Because most clients do not have the time or expertise required to review this data on a regular basis, EDC's systems and technicians are available to analyze your environment for you, making sure your system is doing what it is supposed to and Identifying potential issues before they become problems. If you have questions about your particular environment, call us. The end result is significant savings and problem free operations.

How are savings achieved?

EDC Technologies, provides energy savings by reducing the return line loss. The simplest way to prove savings is to run a test. EDC technologies proves savings through two methods:

On a typical installation we first install the control and record the current operation and consumption of the various systems on the community. After the start up monitoring period is complete we move the control to controlled operation. The monitoring period is subtracted from the from the controlled period to yield the anticipated savings.

In addition to this initial startup savings calculation, clients have the ability at any time, to place the control into a null operation mode and to measure the systems operation in a non-controlled state. After the non-controlled period has ended, the control can be placed back in operation mode and a like period of controlled operation, time can be measured and compared against null mode, thus proving the savings.

Please note that because of seasonal changes, as well as occupancy changes, deciphering the actual savings can be difficult, therefore it is recommended that the two comparison periods be conducted during a time where the weather and occupancy level are somewhat stable.
