That way I charge accumulators only with the energy stored as heat and so I can measure the amount of energy. Here are the results: a heat exchanger warmed up to 999C stores 538MJ, equivalent to 107 accumulators. a heat exchanger warmed up to 998C and a pipe segment warmed up to 999C store 1GJ, equivalent to 200 accumulators.
A pipe that carries about 50 water will fill the tank to about 50% of its capacity. Pumps can be used to fill the entire tank from a low pressure source (such as distant pumpjacks ). The storage tank is often used to store raw materials and excess products from oil processing, allowing a refinery to run without interruptions.
