    Why Our Combined Buffer Tank and Indirect Water Heaters?

    Our Combination of Buffer Tank and Indirect Water heater is a money saving investment for designers and installers looking to use various sources of energy. It's simply a Buffer Tank with two opposite Large Diameter (1½") Inlet/outlets connections, Two Immersed Coils that can be combined in one (with the optional Coils Connection Piece). 

    This gives our combined tank the flexibility to be used for various hydronic applications. They are a smart use when combing Air to Water Heat Pump, Thermal Solar Panels (such as Vacuum Tubes Solar Collectors) and conventional Make-up heat producing equipment (such as Boilers, Fire Places, etc...).  They save you the money for buying one individual Tank for each hydronic application.
