Heat Pump Dehumidifiers
Exchange your humid air for dry air
This uses a technique similar to what you find in an air conditioner. Moisture is removed from the air with the use of a fan that draws indoor air over a heat exchange coil that has been reduced to near-freezing temperatures. Water in the air condenses on the coil and is drained into a tank below. The air is reheated and returned to the room.
Heat pump dehumidifiers can cost anywhere from $100 to upwards of $1000, depending on the feature set. Low-end models can work as effectively as the more expensive heat pump dehumidifier models if you are prepared to do more of the grunt work. This work would include emptying them sometimes up to three times a day (unless you have a hose to drain the water) and changing filters frequently.
The higher-end heat pump dehumidifier units are worth the investment if you don’t have the time or energy for regular maintenance.
Getting the right size heat pump dehumidifier is important. Some might advise that it is okay to get a unit that is too large but this will probably cost you more in energy. You can get a larger one but this might result in you using too much energy – bad for your wallet and the environment.
If you are going to buy the higher-end models there are some things you should look for.
- Always buy a brand name you trust.
- Get a robust warranty.
- Look for an easy-to-program humidistat.
- Automatic shut-off is mandatory.
- An Energy Star rating will save you money over time.
Heat pump dehumidifiers are one of the most effective ways of removing water from the air. In homes where flooding is a problem, you are most likely to find heat pumps. We have seen homes where the heat pump dehumidifier was shut off and the basement was flooded within half an hour. If you need a robust and affordable dehumidifier, this is probably the best kind of unit on the market.
