This boiler is said to be the only one of its type on the UK market and achieves a net efficiency of 103.5% at 50°C flow and 30°C return. The 300 l integral hot-water tank has a recovery rate of 2240 l/h through a temperature rise of 50 K. The heating system serves the bedrooms, communal areas, kitchen and offices. There are 36 radiators and 30 DHW outlets.

The iHE boiler and hot-water package has built-in redundancy and thermo-plastic low-loss headers, highly insulated storage vessel, advanced controls and factory-fitted relief valves. Flues can be vertical or horizontal.

The premix burners and cascading intelligent controls provide a turndown ratio of 15:1. The controls also provide weather compensation, frost protection, hot-water priority and anti-legionella protection for the stored DHW.
