Thermal storage tanks with polyester fibre insulation

Polyester fibre

— it is a thermal insulation based on synthetic fibre made of polyester. The actual capabilities of such a heater directly depend on the density of the fibre and the cost of the filler also depends on the density. Therefore, when assessing the overall quality of such thermal insulation, it is worth looking first of all at the price category of the tank. In general, the insulating specs of polyester fibre are average, somewhat inferior to polystyrene.
