Wallstar 3

The Wallstar 3 is the latest version of Wallstar which has now been in production for 20 years. Unrivalled with its high efficiency, space saving design and quiet, odourless operation while retaining the original Wallstar’s ease of installation and servicing. Supplied complete with anintegrated Balanced Flue, the Wallstar 3 is available in a 20-24kW output.

The new Low Nox Wallstar 3 is ideal for the larger property. Like the Wallstar 1 and Wallstar 2 it is very compact and it still retains all the values of the previous models. It comes supplied with a Low Nox burner to conform to the latest EU Directives regarding low levels of Nitrogen Oxide. The Wallstar 3 is a direct replacement for previous 20/24 and 20/25 models. The hole in the wall is the same size and the flow and return pipes are in the same position.
