Why does the hot water temperature fluctuate from time to time?
Briargate has central boilers that provide both heat and domestic hot water to the entire building (meaning the same system provides both). In the winter we turn the temperature of the boilers up so there is enough heat to give everyone hot water and heat the entire building. So, in general, you will notice the water is slightly warmer in the winter. However, on any given day the temperature of the water may fluctuate as the demand for heat and hot water goes up and down. When it is really cold outside and people are using lots of hot water (first thing in the morning, for example) the temperature may drop some as the boilers are working harder to keep up with the demand. When the demand is less the temperature will be slightly higher and stay more constant.
