The innovative No Calc Long-life technology found on the high-pressure boiler on the Polti La Vaporella prevents the negative effects of limescale for a longer product life cycle without the need for maintenance. The special inner structure – with limescale capturing device and mesh filter – traps even the finest limescale particles and provides long-lasting protection for the boiler's active components. In doing so, boiler maintenance and cleaning is no longer required. What’s more, the special aluminium alloy neutralises the effects of impurities present in tap water.
