Autumn/Winter Reno Winners: Dehumidifiers

Why Home Renovators Need a Dehumidifier

Dehumidifiers significantly shorten drying time for materials like paint, plaster, and concrete, leading to quicker project completion and improved efficiency. By getting spaces dry faster, you reduce the time workers spend on the job, potentially lowering labour costs whilst keeping your renovation on schedule.
Protect your investment. Excess moisture causes wood to warp and swell, leading to sticking doors and buckled floors. High humidity can cause paint to peel or bubble, damaging new and existing finishes. In older homes, trapped moisture can weaken structural integrity over time. A dehumidifier maintains stable humidity levels to prevent all these issues.
Prevent mould and mildew. By lowering humidity to between 30% and 50%, dehumidifiers create conditions where mould can’t thrive, establishing a healthier environment and reducing the need for future remediation. They also eliminate the musty odours associated with dampness that can linger even after cleaning.

Dehumidifier Basics: How They Work

A dehumidifier processes damp air, dries it, and pushes it back into the room. How it extracts water depends on the type.
Desiccant dehumidifiers use an inbuilt fan to draw moist air over a desiccant wheel where moisture is absorbed by a silica gel surface. Before expelling the dry air, it warms slightly, helping regenerate the desiccant material. This warm, dry air is then released back into the room.
Compressor dehumidifiers pull damp air over refrigerated coils, similar to your kitchen fridge. These coils condense the air, creating water droplets that drip into a tank before moisture-free air is expelled. The key difference is that desiccant models release slightly warmer air, offering the additional benefit of increasing room temperature.

Choosing Your Dehumidifier: Types and Sizes

Your choice between desiccant and compressor models depends on room temperature and running budget.

Compressor dehumidifiers are more readily available, with lower purchase prices and cheaper running costs. They’re perfect for most rooms but less efficient in spaces below 10 degrees celsius, making them unsuitable for garages or cold basements. They tend to be bulkier, heavier, and noisier than desiccant alternatives.

Desiccant dehumidifiers excel at removing large amounts of moisture, making them ideal for particularly damp environments and cooler rooms. They work well at all temperatures, operate more quietly, and are lightweight for improved portability. However, they consume more energy and are more expensive to run, though their efficiency means they extract higher water volumes in shorter timeframes.

Rent or Buy?

For short-term projects, renting offers flexibility without the upfront investment. However, if you’re undertaking multiple renovations or need ongoing moisture control, purchasing a dehumidifier becomes more cost-effective. Consider your project timeline, budget, and whether you’ll need the equipment beyond the current renovation before making your decision.
