A lot of old buildings went with the assumption that bigger is better and oversized heating systems. Assuming your old heater is properly sized you can then use this to calculate the size of the new geothermal heater. 1 ton = 12,000 BTU = 3.5 Kw - So if your existing heater is 48,000 BTU then you would need to purchase as 4 ton GeoCool unit.Second Thermal and Fluids Engineering Conference - The cooled salt is stored in a "cold" tank at about about 290°C. These tanks lose around 1% of their stored heat during the night. Molten salt energy storage allows power plants to generate electricity at night using the stored heat, which eliminates problems caused by power variations when solar energy is affected by intermittent cloud cover.
