A washer-dryer costs more, but can washing and drying in one machine be worth it?

Price is not the only way to choose a washing machine. Consider a combined washer-dryer through the work of hanging and bringing in laundry. Check drying capacity, electricity calculations from official specifications, installation and care to find convenience that fits your home.
You are buying more than the ability to dry clothes
Spread each garment, put it on a hanger, watch the weather, then bring everything in. Some days, the work after the washing cycle feels like the bigger task. I think a combined washer-dryer is worth considering without dismissing it solely because of its purchase price.
The attraction is more than dry clothes. It can remove the need to be available at the end of washing to hang a load. For suitable items, a combination machine also avoids transferring wet laundry into a separate dryer.
Sorting, unloading, folding and putting things away still remain. Even so, if rainy-day drying space or another chore after coming home is a burden, this can be worth considering. This is a proposal for thinking about your routine, not a report of the author’s personal use.
Could a rainy evening become easier?
Think of towels during a wet week, or everyday clothes washed at night for the next morning. If the items allow tumble drying, you can reduce occasions when the weather and hanging time determine your plans. Daily drying and using it only on rainy days are both reasonable patterns.
Write down what might change in your own routine. Suppose hanging and bringing in laundry took fifteen fewer minutes per load, with twenty loads a month: 15 × 20 = 300 minutes, or five hours. Fifteen minutes is an invented assumption, not a survey result or the author’s recorded saving.
This does not mean earning five hours of extra income. Count any added sorting and filter care too. Would you use the time to rest or be with family? Starting with the chore you want help with is more useful than deciding that a particular number of minutes must pay for the machine.
“12kg washing” and “6kg drying” are different limits
Check both washing and drying capacity first. For example, Panasonic’s official NA-LX129FL specifications state 12kg for washing/spinning and 6kg for drying. A machine able to wash twelve kilograms cannot necessarily dry that same full load. This matters especially when you combine large batches.
If the washed load exceeds the drying limit, follow the manual, for example by reducing the items to be dried. Before assuming a combination machine can always finish everything automatically, consider how much laundry you normally have.
Check the drying method too. Heat-pump drying removes moisture while circulating warm air; its way of providing heat differs from heater-based drying. Rather than choosing on the method’s name alone, compare the particular machine’s wash-to-dry energy consumption, drying capacity and cycle time together.
Read watt-hours per cycle, not just watts
For electricity costs, look at energy used per cycle in watt-hours (Wh), rather than only the instantaneous power in watts (W). The NA-LX129FL is used here to illustrate reading specifications, not to rank products for purchase.
For rated six-kilogram washing-to-drying operation, the official figures are about 800Wh and 98 minutes in standard drying mode, or 620Wh and 165 minutes in energy-saving mode. Times are guides at a room temperature of 20°C, including filling and draining. Clothes and operating conditions affect results. Energy-saving does not mean a shorter cycle.
Using the manufacturer’s illustrative electricity rate of JPY 31/kWh including tax, 800Wh is 0.800kWh, costing JPY 24.80 per cycle or JPY 496 for twenty monthly cycles. The energy-saving example is JPY 19.22 per cycle or JPY 384.40 for twenty. These are washing-to-drying electricity costs, not the extra cost of drying alone.
JPY 31/kWh is the reference rate revised in July 2022 by Japan’s Home Electric Appliances Fair Trade Conference, not every household’s current tariff. Recalculate with your own rate. The table excludes standing charges, water/sewerage, detergent, purchase and repairs. Compare line drying using your own washing-only and drying pattern too.
| NA-LX129FL mode | Published figures and calculation (reference JPY 31/kWh, tax included) |
|---|---|
| Standard drying mode | About 800Wh / 98 minutes 0.800kWh × JPY 31 = JPY 24.80/cycle Twenty monthly cycles: JPY 496 |
| Energy-saving drying mode | About 620Wh / 165 minutes 0.620kWh × JPY 31 = JPY 19.22/cycle Twenty monthly cycles: JPY 384.40 |
An expensive purchase deserves a full-cost check
Include delivery, installation, required parts or work, collection/recycling of the old appliance, and warranty and repair terms alongside the machine’s price. This is not a price ranking. A large discount cannot make an unsuitable size or drying capacity fit your home.
How often you will dry matters too. Most days of the week and a few times a season are different routines. Electricity savings alone cannot be promised to recover a high purchase price. Consider the value of reducing chores separately from the total your budget can comfortably pay, then look for an option that makes sense on both counts.
If your current machine and drying arrangements work well, there is no need to rush into replacement. But if hanging and bringing in laundry is a daily burden, a higher price need not rule out the option by itself. Choosing the cheapest item is not the only thoughtful way to use money.
Will it fit, dry your clothes and stay maintainable?
Fitting the machine’s body into a space is not enough. Hitachi’s official guidance covers delivery access, door clearance, taps and drainage, the drain pan and floor strength. Include entranceways and corridor corners, and consult the retailer before buying. Consider noise and vibration at the times you would actually use it.
Clothes need sorting too. Do not tumble-dry items whose labels prohibit it; follow both garment and machine instructions. Some items, including oil-contaminated clothing, must not be dried because of fire risk. Heat-pump drying does not make every fabric safe from damage.
Care schedules vary by model. For the LX129F example, the official guidance calls for emptying the drying-lint box after every drying cycle and cleaning the sub-filter about weekly. Do not apply that schedule to every model; follow its manual for drainage and other care too. Less hanging does not mean no maintenance.

Three notes before your next replacement
Start with the amount you want to dry in one load, likely uses per week, and the part of hanging or bringing in laundry you want help with. Then check installation, and line up drying capacity, energy per cycle and total cost. That order keeps the decision grounded in a real chore rather than the longest feature list.
A washer-dryer can be an expensive purchase. Even so, I would positively consider it for someone burdened by weather-dependent drying and timing. Choose suitable clothes, respect capacity and care requirements, and stay within a comfortable budget. Put the convenience of washing and drying in one machine alongside the price when deciding.
Final checklist
- Check which clothes can be dried and the drying limit per load
- Discuss access, door clearance and plumbing as well as floor space
- Calculate costs using watt-hours and your own electricity rate
- Weigh the full price, frequency of use and maintenance before choosing
