What’s the Panasonic NA148XS1?

The NA148XS1 is one in every of Panasonic’s flagship washing machines and boasts the kind of function listing usually seen in pricier machines. It is a full ECONAVI sensor machine that on sure packages will alter each single wash parameter based mostly on the burden, kind and soiling of the load. Simply add soiled clothes and washing powder.

With helpful add-on capabilities like steam motion, wrinkle care and anti-allergy cycle, an 8kg capability and 1,400 spin velocity, this Panasonic affords top-end options all through and guarantees to be one of many 12 months’s greatest washing machines – no less than on paper.

Panasonic NA148XS1 – What’s it like to make use of?

Whereas some model’s flagship washing machines are complicated and require a handbook the scale of the Birmingham phone listing, Panasonic has gone to nice lengths to make the NA148XS1 as straightforward to make use of as attainable.

The rotary programme selector makes quite a lot of sense, the separate on and off buttons are impressed and add-on options are accessed by means of a row of buttons beneath the show. The show itself options shiny blue icons and knowledge on temperature, spin velocity and period displayed in numbers so massive and shiny they may in all probability be learn from the subsequent county.

In its conventional place bottom-right, is a fluff and coin filter that Panasonic recommends checking and cleansing frequently. With its giant porthole door, 8kg capability and equally conventional top-left cleaning soap drawer, this Panasonic couldn’t be extra simple to make use of.

Key to the Panasonic’s actual charms is its ECONAVI Autocare system. This takes wash sensing to the subsequent stage by measuring incoming water temperature, load weight, soiling stage utilizing an optical sensor and the kind of materials combine (the ratio of synthetics to cottons within the load).

From there, some washer maths goes on and the NA148XS1 tweaks the water consumption, temperature, soak time, quantity of detergent, variety of rinses, spin velocity and period to create the proper cleansing regiment.

Not solely does this make programming your washer just about ‘insert garments and press go’, it additionally lets the machine use the bottom quantity of water and vitality required for the precise wash load you’ve got positioned in its capacious drum.

As you will notice from the take a look at outcomes additional down, the ECONAVI AutoCare setting greater than delivers on its Eco credentials, making this our favoured default setting for many washes.

Panasonic NA148XS1 – How noisy is it?

Panasonic has been impressing us with tremendous quiet machines because the first mannequin we examined from the model over two years in the past. Whereas the corporate doesn’t declare any high-tech motor expertise or drive system, the NA148XS1 continues the development with whisper quiet washing at simply 53dB and a really quiet spin at 74dB – precisely what the EU vitality label states, which is much less frequent than you’d think about.

The wash noise is especially good and compares favourably with rivals. 53dB is not any louder than gentle rain outdoors (not with an umbrella up, clearly) and 74dB is not any louder than gentle visitors.

Furthermore, this Panasonic produces a really constant stage of noise all through the wash and spin, with no pops or clicks of valves or relays to disturb pets or youngsters grabbing a artful nap in your kitchen.

Panasonic NA148XS1 – What programmes does it have?

If you wish to take extra handbook management of your washing the NA148XS1 affords a superb unfold of fabric particular programmes too, 15 to be actual. These cowl your primary cottons, delicates, wool, colors and bedding, in addition to an ultra-cool 20-degree wash and 15 and 50 minute fast washes.

5 of the programmes mix the Panasonic’s superior steam perform. There are additionally three wash plus steam programmes, two of that are particularly for gentle hundreds (2kg) of shirts or informal put on. These use steam in the direction of the tip of the wash and promise to scale back creasing or, with some clothes, eradicate all of it collectively.

The third wash and steam programme is Panasonic’s anti-allergy cycle and is right for clothes that contact naked pores and skin when worn, so preferrred for infants or these with delicate pores and skin. The steam penetrates the material, killing off mud mites and micro organism in addition to eradicating particles of pollen.

Unusually, this function is accessible on hundreds as much as a reasonably hefty 5kg, so loads of garments could be handled on this manner. The steam ensemble of programmes is full with two steam solely cycles, refresh and wrinkle care, geared toward rapidly sprucing up small hundreds (as much as 1.5kg) with out going for a full wash.

Panasonic NA148XS1 – How nicely does it wash?

This Panasonic carried out nicely in our wash assessments, though its stain removing skills aren’t the perfect we’ve seen and it’s not essentially the most environment friendly at spinning out water after the wash.

In our important 80% load (6.4kg) take a look at on the UK’s most favoured programme, cottons at 40 levels, we positioned a stain strip within the wash that includes dried on ketchup, juice, turmeric, engine oil, blood and pink wine, and used a number one non-biological detergent.

Typical of contemporary machines, the prolonged cycle took over two and half hours however solely used simply over 1kW of electrical energy and 56 litres of water. Analyzing the stain strip, the juice, blood and pink wine stains had been eliminated utterly, however there was nonetheless a shadow the place the ketchup had been.

The turmeric and engine oil won’t ever be eliminated utterly with out bio powders, however the Panasonic didn’t make a lot of a dent on both with non-bio. The cleansing result’s common for a machine of this value – a lot better than price range machines, however not so good as another manufacturers, admittedly dearer, flagship fashions.

In a collection of different wash load assessments we ran the identical 80% load utilizing the Panasonic’s ECONAVI/Autocare programme, and bought excellent outcomes for financial system of sources. Whereas the load was not closely dirty (so the sensing expertise would cut back vitality, run time and so forth), the identical load completed 45 minutes faster and used half the electrical energy of the cottons wash.

The one draw back was that in an effort to scale back electrical energy the spin cycle was diminished, leaving nearly 50% of load weight in water in the long run wash. Meaning the garments will take for much longer to air dry or tumble dry.

As a half load take a look at we use 40% of capability or 3.2kg of washing. That is nonetheless a good pile of garments, significantly cottons. We ran commonplace cotton at 40 levels and an Eco wash with this load, and as soon as once more Panasonic’s sensor expertise had a dramatically constructive impression on vitality use.

The usual half load used slightly below 1kW whereas the Eco wash drew simply 300W. Like the total wash nonetheless, the time and water used was nearly an identical and the spin effectivity took an actual hit. On the usual half load wash some 38% of wash weight in water remained, which is about common, whereas in Eco it was a whopping 53%.

That is noticeably greater than some machines and means your garments will take longer to dry, particularly when air-drying. A machine just like the Samsung WW80H7410EW left 22% much less water in a half load of garments on its Eco mode, the equal of 700g or greater than a pint. That’s a giant distinction and the Panasonic’s eco run used across the identical quantity of electrical energy.

The steam modes are a little bit harder to check, however we tried a number of shirts on the shirts wash and steam cycle and a fleece that had been uncovered to bonfire smoke on the steam solely refresh programme.

The shirts got here out clear, however we didn’t actually see quite a lot of a distinction within the stage of creasing in comparison with the identical clothes in a traditional wash. The fleece was a more durable take a look at and whereas the Panasonic definitely freshened it up, a feint smoke scent was nonetheless current. With lighter clothes outcomes would little question be higher nonetheless.

Panasonic NA148XS1 – How a lot will it price to run?

With sensor machines, it is vitally troublesome to precisely predict how a lot a machine will price to run as they alter the variety of sources used relative to your washing habits and stage of soiling. Our commonplace calculations are based mostly on 240 cycles per 12 months, with round 200 full hundreds and 40 half hundreds with a 50/50 break up between commonplace washes and Eco.

Utilizing this ratio of washes, Panasonic’s declare the machine affords 40% higher than A+++ efficiency is definitely a little bit modest. This is among the most economical machines to run that we’ve got ever examined.

At simply over 200kWh per 12 months, working prices in electrical energy will likely be simply over £30, which is round £5 higher than many different A+++ machines we’ve got examined. Water consumption can also be spectacular with the identical 12 months’s washing seemingly to make use of round 13 cubic metres of water – or about £20 for these on metered water.

Not solely is Panasonic’s NA148XS1’s asking value affordable for a nicely specified totally featured flagship machine, its low working prices are among the many greatest we’ve got examined.
