The Benefits of a Minus 7 System

Low Running Cost

This system is designed to keep your house at a comfortable temperature of 20°C.  Our advanced technology and intelligent controls will deliver very low running costs.

Low Carbon

Better than 180g of CO₂ per kW heat delivered.

Insensitive to Orientation

Unlike conventional solar panels our roof does not need to face South.  This roofing can be used on the house, garage or outbuilding, therefore allowing it to be incorporated into housing developments with ease.

Visually Unobtrusive

This system is not a bolt on, is visually pleasing, cannot be differentiated from a normal roof from the road, and looks like a new slate roof for many years as it rejects moss and lichen growth readily.
