Hot Water Circulation Measurement


Hot water circulation measurement involves measuring the flow and temperature in the hot water circuit's circulation system in a building. The circulation system ensures that hot water is available quickly at taps and showers without long waiting times. In too cold and stagnant hot water, dangerous bacteria, such as Legionella, can also form. Measuring hot water in the circulation system has several advantages for energy management, comfort, and cost-effectiveness.

Examples of hot water measurement in circulation systems:

Residential buildings. In multi-family houses, hot water may need to be circulated to avoid long waiting times for hot water at taps and showers, especially in large buildings. By measuring energy and temperature, one can optimize operation and reduce energy losses.

Hotels and hospitals. Large buildings with many bathrooms, kitchens, and laundry facilities often have a high demand for hot water. By measuring energy and temperature, one can ensure that hot water is available immediately for guests and patients without unnecessary waste.

Public facilities such as sports halls and swimming pools. Here, large amounts of hot water may be needed at certain times, for example, when many visitors are showering at the same time. Hot water circulation measurement can help adjust availability and optimize energy consumption when demand is at its highest.

Enkey's solution for hot water circulation measurement

Enkey's energy meter for hot water circulation connects wirelessly to Enkey Building Insight®, allowing for near real-time reading of momentary flow and consumed volume. This is cost-effective and facilitates analysis and optimization, as measurement data is collected and visualized automatically.
