So many homes we visit have too much humidity. This means too much moisture in the air, which can make a home damp, and chances are, more costly to heat. We also know that mould thrives in cold, damp conditions. This is not what we want for our whanau.
Where does all the moisture come from? There are three main areas internal moisture will come from in a home, and I'd first like to focus on the bathroom. It’s a wet area right? Isn’t it meant to be that way? Well yes, and no.
A lot of our homes and bathrooms are old and even though an old home can perform well, it needs a few modern fixtures to help it deal with the moisture we create. I'm talking specifically about extraction fans.
Extraction fans in bathrooms, ones that actually suck! are an important part of being able to manage the moisture created in a wet area. The air in our bathrooms gets warm and full of moisture. A good extraction fan can remove that air out of the bathroom at quite a rate. There are specific equations to make sure the extraction flow rate is adequate for the room size, but a recommended ventilation rate by the NZ Building Code is 25 litres per second.
We would love to see every bathroom with a good extraction fan, designed to do its job which is remove moisture from the bathroom and deposit it outside where it belongs. Coupled with good behaviours such as leaving the fan on for 15mins after finishing in the bathroom with the door shut, makes a big difference to reducing the moisture in our home.
We know drier air is healthier for us to breathe and easier to heat, and we know heat is essential for a healthy home.
Do you know an electrician who might like to help us with the install of extraction fans into the homes of whanau who need a helping hand? Contact Jo at firstname.lastname@example.org or on 021 2777 042 if you do.
