UK availability
Vaillant UK’s current heat-pump range contains aroTHERM plus, aroTHERM split, flexoTHERM and aroSTOR. aroTHERM pure is absent from that range, and its current UK supply, MCS status and manufacturer support were unconfirmed on 23 July 2026.
UK-specific product information
A complete UK indoor-unit and package schedule, manufacturer-support route, installation documents, current MCS status and UK guarantee terms remain unconfirmed.
aroTHERM pure should not be confused with aroTHERM plus. Pure uses R32 refrigerant pipework between two units, while plus is an R290 monobloc with a hydraulic building connection.
