Bowman Non-storage Calorifiers provide a simple method of heating water indirectly from a low pressure primary supply. Because both circuits can be pump assisted the surface area required is only about 25% of that required in conventional storage calorifiers.

With new installations their compact modern design will result in a substantial cost and space saving. They also enable an indirect system to be installed replacing a direct system using existing storage tanks. They are of all non-ferrous construction on the secondary side and the construction is such that the tube stack can easily be removed from the shell should cleaning be necessary.
