How to Achieve Drier Homes With The Power Of Heat Pumps

At Goldstar Heat Pumps, we understand the unique challenges Hamilton homes face when it comes to moisture control. Cold winters and our love for long, hot showers can create a recipe for condensation – that unwelcome visitor that appears on windows, walls, and even behind furniture.

However, condensation doesn’t have to be a constant battle. Let’s explore what causes it and how a trusty heat pump for your Hamilton residence can be your secret weapon in the fight for a drier, healthier home.

What is Condensation, Why Does it Happen?

Imagine this scenario: you’ve just finished a relaxing shower, and the bathroom feels like a steam room. As the hot, humid air comes into contact with the colder surfaces in the room, like tiles and windows, the water vapour condenses – forming those pesky droplets. This is condensation in a nutshell.

The main culprit behind condensation is moisture. The warmer the air, the more moisture it can hold. But as the air cools, it reaches a point called the dew point. This is the temperature at which the air can no longer hold all the moisture it contains and condensation forms.

In simpler terms, it’s like when you have a cold drink on a hot day, and you see water droplets forming on the outside of the glass-that’s condensation.

How Can You Stop Condensation?

There are two key strategies to combat condensation: reducing moisture and increasing ventilation:

Reduce Moisture Production

This means being mindful of activities that generate a lot of moisture. Here are a few tips:

  1. Shorter showers: A luxurious soak might be tempting, but a cooler or shorter shower can significantly reduce moisture in the air. This not only helps in reducing condensation but also saves water and energy. Consider installing a low-flow showerhead to further reduce water usage and steam production.
  2. Lid on it!: Keep pot lids on tightly while boiling water or simmering food. This traps the steam and prevents it from escaping into the air. Use appliances that vent externally, like range hoods that exhaust hot, humid air outside.
  3. Dry clothes outside (when possible): Clothes dryers are notorious moisture makers. Take advantage of sunny days to dry clothes on a clothesline or drying rack. If you must use a dryer, vent it properly to the outside to avoid releasing moisture back into your home.
  4. Vent it out: Always use extractor fans in bathrooms and kitchens when generating moisture. Turn them on before starting a shower or bath, and leave them running for at least 15 minutes afterwards to ensure proper ventilation. If your extractor fan isn’t very powerful, consider upgrading to a more efficient model.
  5. Address houseplants: While they add beauty and life to a space, houseplants also transpire moisture into the air. Be mindful of the number of plants you have in moisture-prone areas, and avoid grouping them together.
  6. Seal leaky pipes: Leaky pipes can contribute to hidden moisture problems. Regularly inspect pipes for leaks and repair them promptly to prevent excess moisture from entering your walls and ceilings.

Increase Ventilation

This allows the moist air to escape and be replaced by drier air. Here are a few tips:

  1. Open windows regularly: Even for short periods, opening windows allows for fresh air exchange, particularly after activities that generate moisture. Aim for short bursts of window opening throughout the day, especially during the drier times of the day.
  1. Consider installing trickle vents: These small vents are permanently installed in windows and provide constant background ventilation. This helps remove moisture continuously without needing to constantly open windows.
  2. Whole-house ventilation systems: For a more comprehensive solution, consider a whole-house ventilation system. These systems continuously remove moist air from your home and replace it with fresh, drier air. This not only helps in reducing condensation but also improves indoor air quality, making your home a healthier place to live.

How Can a Heat Pump Help?

Heat pumps are multi-talented marvels when it comes to home comfort. Not only do they excel at heating your home efficiently, but they also have a dehumidifying function. By gently circulating air through the unit, a heat pump can extract moisture from the air, effectively reducing humidity levels.

This two-pronged attack – lowering moisture and providing gentle heating to keep surfaces warm – significantly reduces the chances of condensation forming.


Condensation doesn’t have to be a Hamilton homeowner’s nemesis. By understanding the science behind it and implementing a few simple strategies, like reducing moisture production, increasing ventilation, and considering a heat pump, you can create a drier, healthier, and more comfortable home environment.
