Cold Water Loft Tanks

Traditional cold water storage tanks, also known as loft header tanks or feed and expansion tanks are available in a wide range of capacities and cistern types such as low level tanks, open top and enclosed cold water tanks. These tanks are an ideal solution for new builds or those involved in replacing, maintaining or improving facilities.
