AN INTRODUCTION TO HIGH TEMPERATURE WATER HEATING PLANTS 1. GENERAL REQUIREMENTS 1.1 One of the main advantages of High Temperature Water (HTW) compared to steam systems is the smaller pipe sizes and pumps required due to the greater thermal storage of water. Table 1 shows the influence of temperature differentials on pipe and pump size.
