The HRM X-ternal Max Wallstar Condensing Oil Boiler is available in a 12-16 kW and 12-20kW output, it is an externally mounted wall hung oil fired boiler with many of the advantages and qualities associated with other HRM models. It benefits from using tried and tested components found throughout the HRM Range. 

The compact dimensions of the HRM X-ternal Max boiler means that it can be sited conveniently on an external wall and the option of a brown or cream casing ensures the boiler blends into any environment. The integrated balanced flue means installation is simple and exceptionally fast. The X-ternal Max  is also quiet and odourless as fuel never enters the home.
