I have spray foam in walls and ceiling and an erv that is connected to the bathrooms. Do Ii need exhaust fans in the bathrooms also?
使用ERV或HRV从浴室抽出排风而不是浴室风扇是一个很好的选择。A bathroom fan will depressurize the home and cause air to infiltrate through any holes in the building envelope, whereas if your heat recovery ventilation system is used as a bathroom fan then new air -warmed or cooled by exhaust air depending on the season – is very much preferrable. Does the bathroom fan switch have a timer on it? That is helpful as it will also boost the power of it to help remove moisture. Here is a page aboutwhy balanced air pressure in homes is essential for energy efficiency and durability.
浴室、电吹风和厨房通风口也是如此。其中一间浴室有蒸汽淋浴，你觉得那里湿度过大有什么问题吗?
Just read this for ERV install:
Connecting appliances to the ERV is not recommended. These include: • Clothes dryer
• Range top • Stovetop fan • Central vacuum system • Bathroom exhaust fans unless they are specifically designed for this purpose
These appliances may cause lint, dust or grease to collect in the ERV, damaging the unit.
