Our Boiler Range
Our range includes the unique award winning Wallstar through-the-wall oil fired boiler. First introduced during the early 1980's the Wallstar has evolved to meet the present day demand for highly efficient condensing boilers, and is available in both regular and system versions. To further enhance the HRM range, the X-ternal model was introduced, a fully external boiler which can be used in situations where the benefits of the Wallstar boiler cannot be utilised.
Regular Wallstar: Regular Wallstar is a wall mounted, room sealed, balanced flue condensing boiler with the choice of 3 different outputs ranging from 12 to 24 kW (41-82,000Btu/hr) to suit most domestic situations. The Wallstar concept is simple, the heat exchanger is mounted on the inside of an external wall whilst the combustion equipment (the burner and balanced flue system) is sealed in the wall.
