X1

The X1 Max is available in a 12-16 kW 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. (Also available with a Cream coloured case, see product code X1 Max Cream).

The new X1 Max, X1 System Max is a fully X-Ternal wall hung boiler with a new Low Nox burner to conform to the latest EU Directives regarding low levels of Nitrogen Oxide. These models are based on the Wallstar 1 Max and share the same water jacket and burner thus ensuring they are a reliable alternative if a Wallstar 1 Max is not a viable option. The boiler comes with a remote lock out switch that can be sited within the property and the compact dimensions mean it can be fitted conveniently on most external walls.
