One of the ways of keeping hot and active, primarily in the winter months, is by engaging in physical interest.
Little can be done outside, especially in school during such weeks.
I am a gym teacher, and getting the students into any physical or interests is arduous during the winter season. The entire school has an Heating and A/C and a heat pump upgrade, however the gym was added years after the school was built. The old gym was turned into a school theater. The Heating and A/C professional fitted the new gym with new heating, which was radiant floor heating powered by an electric heat pump. The entire school Heating and A/C system utilized a zone control system, and other energy-saving tips kept the school energy bill manageable, and the expert from the heating industry had commanded, however a smart thermostat regulates the temperature control for both systems to help with indoor comfort. Like our house heating systems, even the commercial ones, such as the one we have at school, need gas furnace service yearly or twice a year. The heating serviceman will be able to determine whether a service will be required during the service. With everyone’s busy schedule at the school, we had a service system tied up with the local heating corporation. When it was time for servicing, the heating company would call the school, and we would agree on the most suitable date! Being in charge of supervising the work helped me learn more about heating. This made work easier for us as well as loyal clients of the heating business. In the meantime, my we had to shove the students into the gymnasium during the P.E. lesson.
