The Potterton Promax combi: the short technical version

As part of the same corporate group as Baxi, Promax benefits from shared UK parts distribution and a diagnostic approach many engineers already know from servicing other group brands. It's aimed squarely at price-conscious households wanting reliable core heating performance rather than smart-home extras, and it fits comfortably in smaller properties with modest hot water demand.
