How can you save energy with Waterworks?

The Waterworks’ system works fine at any temperature and maintain bacterial safety regardless. By reducing the temperature from 70C to 45C on your hot water loop, you will reduce Δt to the environment by 50% and achieve saving in heating at possibly 75%. At the same time, disinfection will still stand at log4 (99.99%) with a continual and residual flow of biocides.

Hot water systems must have 70C water temperature in order to remain safe in a normal case. Where hot and cold water piping are close to each other, the cold water pipes tend to be heated up and hot water pipes cooled down due to the heat exchange between nearby pipes. Secondly, in some cases, heaters are not that efficient over the years so that the hot water is not reaching 70C at heater, and much less at consumer.

In other cases, the ship is being converted from diesel to hybrid or for other reasons converted to electrical heating of potable water. In those cases, you may not even want to heat the water up to 70C as the process of bringing the temperature that high is extremely costly.

The Waterworks’ system is safe to use at any temperature. Whether you want to reduce the power consumption by minimum 50% or you want to stay safe with both hot and cold water between 20C and 50C, you would want to have a Waterworks disinfection system installed – for the safety of your seagoing personnel.

The Waterworks solution is the Sustainable solution, higher safety standard at a lower cost.
