Energy efficiency
The low resistance heat exchanger cell also ensures it does not overheat a space. Buildings with high heat gains already contain a significant amount of heat therefore the heat exchanger only adds back what is necessary to maintain the ambient temperature, balancing this with optimising IAQ. This type of heat recovery is ideal for buildings with hight heat gains within UK temperature ranges. Boasting the lowest energy consumption for a
hybrid heat recovery ventilation unit in the industry, the NVHRe combines 46% heat recovery efficiency with low Specific Fan Power (SFP) of 0.093 W/l/s to maximise energy savings. In addition, the NVHRe features several different operating modes to minimise energy use, enhance IAQ and improve occupant comfort. An intelligent hybrid system, the unit automatically determines when and if mechanical operation is required, ensuring it only operates when absolutely necessary. NVHRe optimises IAQ, comfort and efficiency by automatically switching between natural, hybrid, mechanical ventilation and heat recovery, maximising benefits throughout the year. The unit has four modes: Summer Natural Mode, Summer Mechanical Mode, Winter Mode: Mixing and Winter Mode: Mixing with Heat Recovery. The Summer Natural Mode enables the unit to maximise the benefits of passive ventilation by opening the damper and ventilating with zero cost. The Summer Mechanical Mode enables the hybrid technology to maximise ventilation and cooler air. In Winter the Mixing Mode and Mixing with Heat Recovery strategies offers huge
heating-bill savings as they recycle and recover heat while providing ventilation to ensure excellent indoor air quality and thermal comfort. British designed and manufactured with careful
consideration given to the entire lifespan of the NVHRe, ensuring all key components are recyclable at the end of use, helps provide a more sustainable solution. With energy costs high, building owners are

increasingly looking for energy efficient ventilation solutions, the NVHRe offers this plus its heat recovery reduces the need for additional heating, thus providing savings on space heating costs which also saves floor space within the room too. Easy to retrofit and only requiring small penetrations through a building’s’ external façade, NVHRe is virtually maintenance free, making it a win-win!
