Thermal storage tank for floor heating system A hydraulic separator reduces flow velocity, in the vessel, which allows for two secondary functions - air removal and dirt removal - in one device. 3-in-1 hydraulic separators make air removal and dirt removal primary functions, along with hydraulic separation, with no added piping connections or installation costs.
Locating a thermal storage tank between primary and secondary piping offers the added advantage of hydraulic separation, in addition to having a buffer tank. Separate air and dirt removal devices are still required.
