Moisture is a concern for many homeowners. BC Hydro senior engineer David Rogers provides expert tips on how to combat condensation.

How can you deal with condensation in your home?

The first step would be to find the source of the moisture and minimize it. Once you’ve limited it, using direct heating in a problem area is a really good idea. For example, if your bathroom has a mould problem, try an infrared heater. It works by heating surfaces rather than the air in between, and warmer surfaces mean less condensation.

How can we control humidity in the home?

Energy-efficient bathroom fans work well if your condensation is mainly in the bathroom and caused by hot showers. If you’re in the market for a dehumidifier, an ENERGY STAR® model will save about 15% more energy than non-ENERGY STAR® models. It extracts moisture from the air, reducing the humidity in the room. However, remember that too much natural ventilation will make your home drafty and increase your home’s fuel bills.

How about mould?

Installing wall insulation is a great way to combat dampness. For those with old, solid walls, condensation-based dampness can be a real problem. This is because thin, uninsulated walls are cold, and moisture from the warm air condenses on the surface, making it moist and a breeding ground for mould.

How can a Heat Recovery Ventilator (HRV) help?

Typically, a Heat Recovery Ventilator recovers 70 to 80% of the heat in exhaust air. In the summer, an HRV reverses this heat-exchange process, removing some heat from the incoming air and transferring it to the outgoing air. The result is an HRV exhausts stale indoor air and draws in fresh outdoor air.

Make the switch

If your washer and dryer are a decade old, consider upgrading to ENERGY STAR® appliances. Although energy-efficient appliances cost more initially, over time the savings you will see on your monthly electricity bill should make up the difference.
