Condensation can be a nuisance for many homeowners, causing dampness, mould, and even damaging your property over time. If you’re trying to keep your home warm and energy-efficient, tackling condensation without losing precious heat becomes a top priority. Here’s how a well-designed ventilation system can help you maintain a dry, comfortable, and energy-efficient home.
Why Condensation Happens in Homes
Condensation occurs when warm, moist air meets a cooler surface, causing the water vapour in the air to turn into liquid. In homes, this commonly happens on windows, walls, and in bathrooms or kitchens, where moisture levels tend to be higher.
The Role of Humidity in Condensation
Indoor humidity plays a key role in condensation. Daily activities such as cooking, showering, and drying clothes release moisture into the air. When humidity levels rise, so does the chance of condensation forming. You may not realise it, but excessive indoor humidity can harm your home’s structure and affect your family’s health.
What is the Dew Point, and Why It Matters
The “dew point” is the temperature at which air becomes fully saturated and can no longer hold all its moisture, leading to condensation. When indoor temperatures fall below the dew point, condensation quickly forms. This is especially common in winter when your walls, windows, and even furniture can act as cool surfaces for moisture to cling to. By managing the dew point in your home, you can prevent a lot of the issues linked to condensation.
Why Heat Recovery Ventilation is Key
A heat recovery ventilation (HRV) system can be an effective way to control humidity while keeping warmth indoors. HRV systems continuously extract stale, humid air from rooms like the kitchen and bathroom, replacing it with fresh outdoor air. Unlike traditional ventilation methods, an HRV system recycles up to 97% of the heat from the outgoing air, transferring it to the incoming air. This keeps your home warm and reduces the risk of condensation.
How HRV Balances Humidity and Heat
With an HRV system, you don’t need to open windows to let moisture escape, which can lead to heat loss. Instead, it automatically maintains optimal humidity levels by filtering in fresh air and extracting excess moisture. Some systems even have sensors that adjust airflow based on current humidity levels, giving you a hands-off solution to condensation.
What You Can Do to Minimise Condensation
Alongside using HRV, here are a few quick ways you can reduce indoor moisture levels:
- Ventilate rooms during and after cooking or showering.
- Use extractor fans or open windows slightly in high-humidity areas.
- Avoid drying clothes indoors whenever possible.
- Monitor your home’s humidity with a hygrometer. Aim for 40-60% relative humidity.
When to Seek Professional Help
If condensation and mould remain persistent, it may indicate a bigger issue. Installing a heat recovery system could offer a long-term solution, but it’s important to select the right unit for your home’s size and layout. A professional ventilation company, like Smart Ventilation, can assess your needs and recommend a tailored solution.
