Now we have a devoted check lab that we use for all of our tumble dryer evaluations. This lets us precisely evaluate the efficiency of every mannequin, so you possibly can belief that our evaluations are correct.
We use the identical batch of garments for every check.
Our efficiency exams
Drying efficiency: We put our garments right into a washer and run a brief cycle to get them moist. We use a washer, as we wish our garments to be spun, in order that water is evenly distributed and the garments are as moist as they’d be from an actual wash: you possibly can’t obtain this by merely ducking them in water.
We then run the cabinet and hanging dry choices, weighing the garments earlier than they go in and once they come out, to see how a lot water is eliminated. Dryers will take away fibres, so we measure if garments have misplaced weight consequently, and the way a lot has gone.
Power consumption: All tumble dryers are measured for power consumption to see how environment friendly they’re. We quote this determine as kW/h, which is the usual measure of power utilization.
Working prices: Utilizing the power label figures, we work out the typical value per full load of tumble drying. This then lets us work out working prices for the 12 months. We do that by understanding the typical UK drying masses per 12 months, assuming 160 masses and three completely different load quantities: 6kg (960kg per 12 months), 4.5kg (720kg per 12 months) and 3kg (480kg per 12 months).
We then work out what number of full masses every dryer would take to finish the total quantity. For instance, a 10kg dryer used at full capability would solely want 96 masses to finish the excessive quantity of washing. With bigger machines, increased cycle prices are sometimes offset by having to run fewer masses. This then lets us work out yearly working prices on an excellent floor.
Noise and ease of use exams
We measure the sound in dB of every tumble dryer. We take measurements throughout the usual drying cycle.
We clarify how straightforward every machine is to load. We look at how straightforward it’s to empty the machine on the finish of cycle and the way straightforward the filters are to wash.
We look at how straightforward every machine is to programme and the way clearly its controls are laid out. We clarify the drying choices out there and what they do, too.
The place we now have good machines, we hook each as much as our web and use the supplied app, and price how straightforward that’s to make use of. We additionally check with Amazon Alexa and the Google Assistant if there’s compatibility.
Scoring and verdict
After all of the exams are full, we rating the machine utilizing the standards talked about right here. We first verify to see if the machine’s efficiency matches the producer’s claims and that every one the options work as anticipated and marketed.
