X1 System

The X-ternal sealed system boiler is based on the regular X-ternal model, but with the circulating pump, expansion vessel and safety valve conveniently located within its casing. The X-ternal System is ideal for the smaller property typical of many of today’s new builds where space inside the home is at a premium. It is available in a 12-16kW output. (Also available with a Cream coloured case, see product code X1 System Cream).

The new X1, X1 System 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 and share the same water jacket and burner thus ensuring they are a reliable alternative if a Wallstar 1 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.
