Cost of Using a Tumble Dryer

Most people are probably aware that using a tumble dryer can increase electricity bills by quite a lot – but just how much is the cost of using a tumble dryer to dry an average load of clothes ?

Using a tumble dryer can cost anything between €2 and 60 cents to dry an average load of clothes.

A C-rated 8kg tumble dryer will typically use around 585kWh/year or almost 5 kWh per load.

An A++-rated 8kg heat pump tumble dryer will use 230 kWh/year based on the official rating standard  – that is less than 2kWh per load.

This would represent a saving of around €150 a year in running costs on average, meaning that for homes that do a lot of drying, paying more for an efficient dryer makes sense.
Of course, using the washing line is much cheaper again.

The actual energy usage and cost of using your dryer will depend on what energy rating it has.
We looked at a small selection of currently available tumble dryers and compared their electricity usage
( If you have a tumble dryer older than 6 years it is very likely to be using even more electricity than the examples given below.)

We calculated the electricity costs using the current standard electricity unit rate charged by Electric Ireland of 35.83c per kWh inclusive of VAT.  (March 2024 .) Lower unit rates may be available from other suppliers.
(See Cheapest Electricity Providers ).

The tumble dryer with the most expensive running cost in our survey uses more than three times the electricity per year than the best performing one. The best-performing tumble dryers will usually cost more to buy than the poorer-performing ones – but over the lifetime of the dryer you can recoup the extra costs with the savings in electricity bills. (And help save the planet !)

Tumble Dryer Running Costs Compared

Tumble Dryer
Cost per
Bosch  Serie 4 WTN85280GB
Grundig GT56824CW55c€63A+++€700

For example – comparing costs over just 5 years : If you bought the  cheaper Tumble Dryer – the Logik at €300 with a B rating – your total cost including electricity over 5 years would be around €1280
Buying the  A+++ rated model for €700 would end up costing around €1015  over 5 years. (€265 less).

Buying the A++ Beko model for €520 would result in a €945 total cost over 5 years. (€335 less)

The savings will work out as more over a longer period and will be bigger as electricity rates increase. You can click on the links to see current prices and find out more about each tumble dryer in our small survey.

If you have an older vented tumble dryer with an energy rating as bad as  C or D – then average running costs will be even higher than any of the figures shown above  – possibly in the region of €300 a year or more. You should be looking at replacing it as soon as possible.

** Annual electricity cost based on  888kg of drying a year and calculated using the manufacturer’s specification and energy usage figures. Manufacturers’ figures usually assume that washing has gone through a 1400rpm spin before being put in the dryer .
The electricity usage figures shown above will be what to expect in optimal conditions.  If you don’t clean filters or don’t fully spin the washing then the drying costs will be more than shown in the table above.
