Why measure the energy for hot water circulation?
Reduce heat losses. Hot water circulation systems transport water in a piping system, which can lead to heat losses if water is circulated more than necessary. By measuring the circulation, one can optimize the flow and reduce heat losses, which decreases energy consumption.
Minimize the risk of dangerous bacteria. Legionella is a bacterium that multiplies in lukewarm water. The bacteria thrive best when the water temperature is between 20 and 45 degrees Celsius. To avoid legionella, one should ensure that the temperature is at least 50°C in the hot water circulation.
Improved comfort for residents and users. By having a well-adjusted hot water circuit, one ensures quick access to hot water. This means shorter waiting times at draw-off points, which improves comfort for the residents or users.
Lower energy costs. Circulation of hot water requires energy, both to keep the water warm and to pump it around the system. By measuring and optimizing the hot water flow, one can reduce energy costs for the entire building.
Maintenance and detection of deviations. Measuring the circulation flow makes it easier to detect deviations in the system that may be due to problems, such as leaks or excessive consumption. This can lead to reduced wear and fewer repairs.
Environmental benefits. Reducing energy losses and water usage contributes to lower carbon dioxide emissions and a better environmental impact, something that many property owners and tenants prioritize today.
