Tristar Thermal Store Cylinder

The Tristar Thermal Store is a high-performance hot water storage solution designed to work with a wide range of traditional and renewable heating systems. Manufactured in the UK from either Grade 3 Copper or Duplex Stainless Steel , it provides reliable mains pressure hot water, excellent flow rates and an efficient solution for domestic hot water and space heating.
