The Envirovent MIV Loft Mounted Unit is a positive input ventilation unit for bungalows with a loft space and radon problems. This unit is more suited to bungalows with narrow hallways so that air air supply valves can be placed in two locations.
The Envirovent MIV Air Source takes maximum advantage of the benefits of solar gain from the loft space throughout the year. Solar gain is the natural accumulation of heat from the sun on bright days.
Temperatures in the loft are on average 3°C higher than outside and as the MIV unit draws fresh air from the loft and delivers it into the property, this results in a saving of around 500 Kilowatts of energy per year in an average family home - equating to significant savings in annual heating costs.
Going beyond traditional input ventilation, the MIV® Air Source has the facility to source cooler air from outside the building when the temperature in the loft space rises above 25°C.
