Added insulation to hot water tanks and pipes

Overview

Gas based hot water heating is often very inefficient, because the system circulates hot water permanently in a loop around the school so hot water is immediately available when someone turns on a tap. The circulatory pipework used to do this is often poorly insulated, and loses heat. Often these types of systems are only 20% efficient compared with direct point of use water heaters which are often over 90% efficient. Energy Sparks would recommend switching to point of use electric water heaters, but if this is not possible we recommend that you ensure that your hot water pipes and tanks are well insulated.
