The Fresh-r retains so much heat inside that additional heating is hardly necessary. This is a difference of 1.5 tons of CO2 each year for an average home.
Heating our homes costs huge amounts of energy. Considerable savings can be achieved with insulation and closing off gaps. But you then need to ventilate with re-used heat. Otherwise, you simply blow the heat off.
Fresh-r reuses 86% of the heat that is otherwise ventilated away. Furthermore, Fresh-r ventilation is demand-driven: so only when it’s necessary. This saves considerable amounts of energy compared with the use of standard mechanical ventilation.
