Heat Pump Dryer Installation: What You Need to Know

One of the biggest advantages of heat pump dryers is their installation flexibility. Unlike vented dryers that require complex ducting to the outside, heat pump dryers can be placed almost anywhere in your home. However, getting the installation right ensures optimal performance, safety, and longevity. This guide walks you through everything you need to consider.

Before Delivery: Preparation Checklist

Before your new dryer arrives, take time to prepare the installation space. Proper preparation prevents delays and ensures a smooth setup.

Measure Your Space

Verify that your dryer will fit in the intended location, accounting for clearances:

• Minimum clearances: 10cm on sides, 10cm at rear, 3cm at top (more for stacking)
• Door swing: Ensure the door can open fully without hitting walls or other appliances
• Access path: Measure doorways, hallways, and stairs the dryer must pass through

Check the Flooring

Your dryer needs a solid, level surface to operate correctly. Suitable flooring includes:

• Tile or vinyl flooring (ideal)
• Concrete (may need rubber mat for vibration dampening)
• Wooden floorboards (ensure structurally sound)

Avoid placing dryers directly on carpet, as this restricts airflow underneath the machine and can cause overheating.

Electrical Requirements

Heat pump dryers in Australia run on standard 240V power and typically draw 2-3 amps during operation—much less than conventional dryers. However, proper electrical setup is still essential.

Power Outlet

• Use a dedicated wall outlet—don't share with other appliances
• Outlet must be easily accessible (not behind the machine)
• Never use extension cords or power boards
• Outlet should be RCD (safety switch) protected

Ventilation Considerations

While heat pump dryers don't need external venting, they do release heat into the surrounding room. Proper ventilation ensures efficient operation and prevents moisture buildup.

Room Ventilation

Ensure your laundry space has:

• A window, door, or mechanical ventilation to allow air circulation
• Minimum room volume of 10 cubic metres (approximately a 2m x 2m x 2.5m room)
• Ability to dissipate heat during operation

Enclosed Spaces

If installing in a cupboard or small enclosed space:

• Install ventilation grilles in cupboard doors (top and bottom)
• Consider a small exhaust fan for continuous airflow
• Leave cupboard doors open during operation when possible
• Monitor for excessive heat buildup initially

Water Drainage Options

Heat pump dryers extract water from your clothes, which must be managed. You have two options:

Option 1: Water Collection Tank

The simplest approach uses the built-in collection tank:

• Tank typically holds 3-5 litres
• Must be emptied after every 1-2 loads
• Dryer will pause and alert you when tank is full
• No plumbing required

Option 2: Continuous Drain Connection

For convenience, connect to a permanent drain:

• Use the included drainage hose (or purchase separately)
• Connect to a floor drain, sink drain, or standpipe
• Ensure the hose runs downhill—water cannot be pumped upward
• Maximum drain height is typically 80-100cm (check your manual)
• Secure connections to prevent leaks

Installation Steps

Step 1: Unpack and Inspect

• Remove all packaging materials, including internal transit bolts or foam
• Check for any visible damage from shipping
• Locate all included accessories (drain hose, manual, warranty card)

Step 2: Position the Dryer

• Move dryer to installation location
• Maintain required clearances on all sides
• Do not tip more than 45 degrees during moving

Step 3: Level the Machine

• Use a spirit level on top of the dryer (check front-to-back and side-to-side)
• Adjust the four feet until perfectly level
• Lock adjustable feet in position
• Test stability by pushing gently—dryer should not rock

Step 4: Connect Drainage (if applicable)

• Connect drain hose to dryer outlet
• Route hose to drain location avoiding kinks
• Secure connection at drain

Step 5: Connect Power

• Plug into dedicated power outlet
• Ensure cord is not pinched or kinked
• Do not use adaptors or power boards

Step 6: Initial Setup

• Power on and complete initial setup wizard
• Set language, time, and preferences
• Run a short test cycle with a small load

Stacking Installation

Many households stack their dryer on top of a front-loading washing machine to save floor space. This is possible with most heat pump dryers but requires proper equipment.

Requirements for Stacking

• Stacking kit: Use the manufacturer-approved stacking kit (usually sold separately)
• Compatible washer: Bottom machine must be rated to support the dryer's weight
• Secure mounting: Kit must be installed according to instructions—never stack without proper mounting
• Height clearance: Ensure stacked height allows comfortable access to controls

Post-Installation Checklist

After installation, verify everything is set up correctly:

• ☐ Dryer is level and stable
• ☐ All clearances maintained
• ☐ Power connected to dedicated outlet
• ☐ Drainage working (tank or continuous drain)
• ☐ All transit materials removed
• ☐ Test cycle completed successfully
• ☐ Warranty registered with manufacturer

Common Installation Mistakes

Avoid these frequently seen errors:

• Leaving transit bolts in place: Causes excessive vibration and noise; can damage internal components
• Insufficient clearance: Leads to overheating and reduced efficiency
• Unlevelled machine: Causes vibration, noise, and uneven wear
• Kinked drain hose: Prevents proper water drainage; dryer stops mid-cycle
• Poor ventilation: Results in longer drying times and potential moisture problems

Taking time to install your heat pump dryer correctly pays dividends in reliable, efficient operation for years to come. If you're uncertain about any aspect of installation, consult your user manual or contact the manufacturer's support line.
