Possible savings by the usage of INNOWATECH Aquadron® stations

By the continuous treatment of complete water at the entrance to the building and the sustainability of Anolyte in the whole piping system, a contamination  of  drinking water installation with germs (i.e. Legionella), Viruses and fungi can be impeded. A „thermal disinfection“ of the warm water circuit at temperatures ≥ 60°C is not necessary anymore.

In the warm water circuit lose thermal energy is lost to environment continuously. At the end of circulation (flyback) the warm water flows back into the boiler of the heating with a lower temperature between 45-57°C than it left. The loss is dependent on the age, isolation and piping length of the system. This thermal loss has to be substituted, so that the warm water can start the next circulation cycle with the claimed 60°C (flow). The more water per hour passes through the boiler and the larger the temperature gap between incoming and outgoing water in the boiler is, the more heating energy is needed.

The temperature of 60° C is not needed by the user at the tap. It is even dangerous because of the possibility of scalding for small children or demented old aged people. The only reason for the use of the high temperature is the germ protection. But even with 60°C this is very often not successful as in the periphery of not well isolated or wide spread piping systems the temperatures remain much below. Also by a non-optimal hydraulic in the system this can occur.

With the use of INNOWATECH technology there is no need of a high temperature for the germ control because this job is perfectly done by the Anolyte. This allows reducing the temperature at the boiler outlet from ≥ 60°C to 45-50°C (depending on circulation and object).  To run at a lower temperature reduces the loss of energy in the circle (see: rules of thermo dynamic – physical chemistry).

Our experience is for example, that a temperature decrease of 5°C in a middle size hospital reduces heat loss by about 1°C.  Assuming energy prices of about 0.1 €/kWh calculations show that at a circulation flow of 1 m³/h this saves already 1000.- €/Year. At most installations circulation flows are much higher than 1 m³/h thus providing far higher cost savings. (You can calculate the saving potential per year very easy with the formula: Reduction warming loss x circulation capacity x 1.000  )

Beside the cost reduction also an emission reduction of CO₂ is resulting.

In connection with heating systems with solar water warmers, the operation time solar collectors can be expanded dramatically when the working temperature in the warm water reservoir can be reduced. In these cases the economic and environmental benefit is even much higher.

Due to the fact of shrinking resources and global warming at INNOWATECH we do not see a sustainable solution in wasting huge amounts of energy by keeping temperatures in warm water installations above 60°C and perform repeated thermal disinfection cycles with 70°C ore more. The future will show that we can not afford this.
