It is used to absorb, temporarily store, and release heat in heating systems with different heat generators.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe tank is designed as a buffer tank without a heat exchanger. The vessel is made of sheet steel, raw on the inside and coated with corrosion protection paint on the outside. Depending on the version, it is equipped with permanently bonded thermal insulation made of polystyrene foam or rubber mat. The PSTW 300 variant is rated with energy efficiency class C for polystyrene foam and energy efficiency class B for rubber mat.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe buffer tank supports more uniform system operation when heat generation and heat consumption differ in time. With a capacity of 318 liters, this variant offers greater buffer capacity within the PSTW series and, with a diameter of 650 mm, remains easy to plan for many utility rooms.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe WGJ-B PSTW 300 can be used in heating systems with boilers, solar thermal systems, or heat pumps. The variant features side heating connections, an upper KP1 connection, multiple sensor positions, a drain or flushing connection, and two heating element positions for approved electric heating
