According to the climate characteristics and building needs of the UK, the following areas and scenarios are suitable for the use of energy recovery ventilators (ERV):

1. High-humidity coastal and rainy areas

‌Western and northern Scotland‌

Annual rainfall is as high as 3000mm or more. ERV can effectively balance the indoor and outdoor humidity difference and prevent condensation and mold growth

‌Wales and northwest England (such as the Lake District)‌

The marine climate leads to humidity in winter. ERV maintains indoor dryness through humidity exchange function and reduces heating energy consumption

2. High-density cities and new buildings

‌London, Birmingham and other large cities‌

New residential and commercial buildings must comply with the requirements of the Building Energy Efficiency Regulations (2025 version) and must use energy recovery systems;

 ERV can improve ventilation efficiency and save energy in modern buildings with high airtightness

‌Passive House and Green Certification Projects‌

ERV meets the PHI (Passive House Institute) requirement for heat recovery rate ≥ 75% , adapt to zero-carbon building standards

3. Public and commercial facilities

‌Hospitals and schools‌

ERV ensures indoor air quality (IAQ) and reduces the risk of virus transmission through high-efficiency filtration and humidity control

‌Office buildings and shopping centers‌

Combined with intelligent control systems (such as CO₂ concentration monitoring), ERV can dynamically adjust the fresh air volume and reduce air conditioning energy consumption 

by more than 30%

4. Special industrial and transportation scenarios

‌Metro tunnel ventilation‌

The use of earthquake-resistant ERV (such as Yingfei YFTNV series) can cope with the piston effect and realize emergency smoke exhaust, and the energy consumption is reduced by

 32% compared with traditional systems

‌Chemical plant‌

The anti-corrosion designed ERV is suitable for highly corrosive environments, extending the equipment life to more than 10 years

5. Economic considerations

Although the initial cost of ERV is higher than HRV, the British government provides a 15% tax credit for energy-saving renovation of commercial buildings, and the investment recovery 

period can be shortened to within 2 years
