Balance point
In any thermal heat exchange process, a mixture of two energy flows will result in a new stage or phase called the balance point.
Balancing
Balancing of heating and cooling systems is performed to ensure that the correct amount of water is present at all consumption points.
Balancing valve
During commissioning of heating and cooling systems, hydraulic balance is often achieved using balancing valves; static or dynamic.
Biocide
Biocide is a chemical added to the make-up water for evaporative applications such as condensers and cooling towers.
Biofilm

Boiler
Consumers who live in areas with no district heating have to use their own boiler to produce central heating. A boiler installation has the following components: burner, nozzles, boiler casing, hot-water tank (integrated or separate) and a chimney.
Boiler shunt
The primary task of the boiler shunt is to ensure that the difference in temperature between the top and the bottom of the boiler is not too high. A high temperature difference can cause tensions in the material and thus reduce the life of the boiler.
Brackish water
Brackish water is water that has more salinity than fresh water, but not as much as seawater.
