Wallstar System

The Wallstar sealed system boiler is based on the regular Wallstar model, but with the circulating pump, expansion vessel and safety valve conveniently located within its casing. The System Wallstar model is available in a 12-20kW output and has all the distinct benefits of the regular Wallstar.

The new Wallstar System Low Nox is ideal for mid to large properties. Like the Wallstar 1 and Wallstar 3. It is very compact. It still retains all the values of the previous models and comes supplied with a Low Nox burner to conform to the latest EU Directives regarding low levels of Nitrogen Oxide. The Wallstar System is a direct replacement for previous 15/19 and 15/20 models. The only execption is the very early 15/19, pre 1999 (half moon version) that shared the same size water jacket as the smaller model. Please call the office for further information.
