I compared Asda’s self-heating mattress topper to a leading brand to slash bills

News

THE cold nights seem to be sticking around and self-heating mattress toppers are a great energy-saving way to keep warm.

While other gadgets like electric blankets and throws cost cash to use, the toppers are completely free to run.

That’s because they work by reflecting your body heat back at you, this is done through a layer of foil within the topper.

The leading and most popular brand option on shelves tends to be Silentnight’s Heat Genie Self-Heating Mattress Topper.

It has rave reviews online and is recommended by shoppers as a bargain alternative to putting the heating on.

But it comes with quite a hefty price tag costing £45 for a double-size at Argos.

Luckily though other chains such as Asda have their own version of the nifty gadget.

Asda’s Self Heating Mattress Topper costs just £30 for a double, but how does it compare to the big-brand alternative?

We put the two toppers to the test and compared them based on quality and heating ability.

I hadn’t tried one of the gadgets before so was intrigued to see how they lived up to the hype.

Of course, it’s important to bear in mind that there can be a hefty upfront cost.

But when taking into account the savings on your energy bills they could be a pretty savvy investment.

I rated them out of 10 for both quality and efficiency, giving each a combined total out of 20.

Silentnight’s topper was easy to fit on my standard double bed, it’s designed like a standard fabric topper with elastic straps that fit around the corner of your mattress.

The first thing I noticed when removing it from the packaging was how thick the material is.

Its heat-reflecting foil is combined with a thermal lining and a quilted top layer adds a 7.5 tog, making it pretty dense.

I tucked myself in and waited for it to work its magic.

It took longer than I had expected, I began feeling warm after around five minutes but after that, it was pretty consistent.

Because the topper reflects your body heat, I could feel that other areas I wasn’t lying on were much cooler.

It did take around 10 minutes to feel completely toastie.

The material itself was super soft and cosy, it felt very luxurious and is a decent topper in its own right.

Taking Asda’s topper out of the packaging, it felt thinner than Silentnight’s as the top layer didn’t have the same density.

It went on pretty easily but needed slightly more adjusting to fit exactly.

I felt Asda’s gadget warmed up slightly quicker but the temperature was more or less the exact same.

The topper was a bit firmer and wasn’t as soft as the branded alternative, which meant it didn’t feel quite as cosy.

That being said it was definitely comfortable and would be an added layer to your bedding to give you a good night’s sleep.

Out of the two, Silentnight’s was definitely higher quality, it was much more plush and soft.

But Asda’s gadget matches the brand in terms of efficiency, and both mattress toppers will keep you a bit more cosy while you’re sleeping.

At a £15 price difference, if you’re not as fussed about the luxury feel, it could be worth saving some cash and opting for the supermarket version.

Although, it’s worth pointing out that neither boosted my temperature by a huge amount.

If you’re really looking for something to keep you warm you might consider spending the same amount of money on an electric blanket or throw instead.

Bear in mind though that both of these two gadgets do come with a running cost, but it’s pretty low at around 3p an hour.

Or you could use a hot water bottle in conjunction with the self-heating topper, which would cause it to reflect more heat into your bed.

It may be tempting to turn the heating on as temperatures drop.

Luckily, there are several other ways to keep yourself and your warm without bursting the bank, and you don’t need the central heating on.

Electric blankets are a great way to keep you warm during the colder months.

You just have to fit them on top of your mattress, plug in and wait for the heat to start emanating out.

You can get them on the cheap and they don’t cost much to run either.

Another handy tip uses home furnishing most of us already have in our homes.

Keeping all your curtains and blinds closed throughout the evening and the day if you can can keep the heat inside your home.

That’s because they act as a barrier between your windows and the inside of your home.

The thicker our curtains are the more they’ll stop heat from escaping, especially if you have drafty windows.

That means you’re making the most of the warmth inside the house.

Insulating walls, pipes and your loft can be very cost-effective.

Installing installation in these parts of your home can prevent draughts from flowing through the gaps and keep your house warm.

Most DIY stores sell foam lagging, which can be cut to fit the pipes and fixed in place with insulation tape.

Previous estimates suggest that loft insulation can save you up to £315 per year on your energy bills, so it pays for itself fast.

According to experts, it’s not too difficult to insulate it yourself – however, those who need their walls insulated are better off calling experts.

One of the most effective and easiest ways to spend less energy and save money is draught-proofing – and there are plenty of ways homeowners can do this.

In the past engineers have suggested opting for self-adhesive foam strips, which are perfect if there’s a gap between your door and the floor.

Even small areas, such as keyholes and letterboxes, can allow cold air into homes, so it’s important to get these covered too.

You can pick up two rolls on Amazon or just £1 for a metre, all you have to do is cut off the amount you need and peel off the film and stick it on where you need it.

The slightest change could make a big difference.

Another alternative to central heating is plugging in an electric heater.

You don’t have to fork out buying a full-sized gadget, you can opt for a mini one instead.

They obviously won’t give off as much heat, but they can be useful for keeping you warm if you’re sitting in front of the TV or working from home.

They won’t cost as much to run as a larger heater either, and they have a lower upfront cost too.

Another handy and stylish option for your home is to lie a rug down.

It’s pretty simple, as with insulating your walls and loft, rugs will help insulate from the ground up.

A rug also helps keep your feet warm if you’ve got tiles or wood flooring.

They help to keep heat in and also add sound insulation too.

You can buy area rugs from most homeware retailers.

We found one on Dunelm’s website for just £30, and you can find lots of different sizes to fit the size of your room too.

This one may sound a bit odd but it can help give the warmth in your home a little boost.

By simply keeping your oven door open after you’ve cooked you could warm your house.

This is something that has been recommended before by savvy savers.

It essentially means that rather than heating the inside of your oven when you’re done cooking, you can at least make the most out of the heat which has built up inside.
