Before initially filling your heating system with thermal fluid try to estimate how much to have on hand for startup. Thereafter, you should know exactly how much is required. The Figures shown below can help you estimate the amount needed for typical plants. If your plant components differ from the ones listed, add or subtract accordingly.
