Westinghouse Heated Blanket, Queen

The Westinghouse flannel queen (model KTHB-QAVV-Q) states 100 W at 120 V, 60 Hz in its first listing bullet - the lowest rated draw of any bed blanket in our registry, and about 15 cents for an eight-hour night at the current US average rate. It is a single-controller queen at 84 x 90 inches in double-layer 200 GSM flannel, with 10 heat levels, a 1 to 12 hour timer, a memory function and ETL and FCC certification. It states no warranty term. Best for a solo sleeper, or a couple who genuinely agree on temperature, who wants the running cost settled before buying.

100 W stated on the listing, 10 heat levels and a 12-hour timer. The cheapest bed blanket to run of anything here that publishes a number at all.

Where the wattage comes fromWestinghouse states it directly in the first listing bullet: "a 100W, 60Hz heating blanket". This is a single-controller queen, so 100 W is the whole blanket rather than one side of it.

100 W x 8 h = 0.80 kWh, x $0.1834/kWh = $0.15 per night

What it does well

  • 100 W published, the lowest figure any queen here stands behind
  • 10 heat levels and a timer selectable to any hour up to 12
  • Memory function, so you are not resetting it every night
  • Machine washable on cold, gentle

Where it falls short

  • One controller only, so the whole bed runs at one temperature
  • No warranty term on the listing
  • Westinghouse's other queen listings do not publish a wattage, so the figure is model-specific

Who this is forA solo sleeper, or a couple who genuinely agree on temperature and want the lowest running cost on the page.

Skip it ifSkip it if you share a bed with someone who runs hot. There is one controller and no way to split the blanket.

How we ranked these

  • What the listing publishes, quoted: wattage, voltage, heat levels, timer, fabric weight, dimensions, certification and the wash and dry rule.
  • What it does not publish, named rather than glossed: the warranty term.
  • How it compares inside its own brand, because the interesting fact about this blanket is that seven of its siblings publish nothing.
  • How it compares at the same size, because the real question is whether to buy this queen or a different one.
  • Not assessed: warmth, softness or durability. We have not handled this blanket.

We have not handled these products and we do not claim to have. The full method, including the rubric weights and what we refuse to claim, is on our methodology page.

The number, and exactly what it means

Westinghouse puts it in the first bullet rather than burying it: a 100W, 60Hz heating blanket. On a site built around that figure it is worth being precise about what it does and does not tell you.

  • It is the whole blanket, not one side. This is a single-controller queen, so 100 W covers the entire 84 x 90 inches. A dual-control blanket's headline wattage is usually the sum of two controllers, which is a different kind of number.
  • It is a ceiling, not an average. Every thermostatic blanket cycles its element off once the bed is warm. 100 W is what it draws while actually heating, so a real night costs less than the arithmetic below, not more.
  • It is model-specific. Westinghouse publishes a wattage on one of the eight Westinghouse products we track. Nothing about this figure can be carried across to the king, the throws, the wearables or the 12V blanket.

Rated wattage is the ceiling, not the average. A thermostatic blanket cycles its element on and off once the bed is warm, so an all-night bill usually lands below the rated-watt figure. We publish the rated number because it is the only one the maker stands behind, and we do not estimate a duty cycle for a blanket we have not measured.

For scale inside the same size class: the Bedsure dual-control queen publishes dual 110 W, so 220 W with both sides running and 110 W with one. Run one side of the Bedsure and you are paying roughly what the whole Westinghouse costs. Run both and you are paying about double. Every published figure in the category sits in the watts, by model.

One listing out of eight, which is the real story

This blanket is the most interesting product in the Westinghouse range precisely because of what surrounds it. Its king, its sherpa throw, its faux fur throw, both wearables and its 12V car blanket state nothing at all about power draw. Same brand, same category, same retailer, same year.

What that proves is useful: the information exists. A manufacturer that can print 100 W on one listing is not withholding it elsewhere for want of knowing. The omission is a listing-copy decision rather than a manufacturing secret, and once you have seen it on one product you can stop giving the others the benefit of the doubt.

What it does not let us do is infer the rest. Whether the Westinghouse king draws more, less or the same is unknowable from what is published, and we will not guess. The brand-by-brand picture is on Westinghouse heated blankets.

The gap: no warranty term

This listing states no warranty period. Neither does the product's manufacturer record, which carries a model number and a part number and leaves the warranty field empty.

That is not universal at Westinghouse. Exactly one of its eight products in our registry states a term - a five-year warranty on the foot-pocket throw, whose listing has since been withdrawn - and one more says a warranty is offered without naming a period. The other six, this blanket included, state nothing.

So the trade at this size is unusually clean. Westinghouse gives you the number and no term. Beautyrest's queen gives you five years in writing and no number. Sealy's dual-control queen gives you a five-year term and no number either. Why a term matters more here than on most purchases - the failure is invisible until it is not - is on how long do electric blankets last.

200 GSM flannel, and why we report it as the lightest

The listing states double layer 200 GSM flannel on both faces. In our registry that is the lightest published face weight of any bed blanket, level with the Sealy queen. Bedsure's king states 290 GSM over 200 GSM sherpa; Bedsure's GentleSoft queen states 240 over 200.

We are not going to tell you a heavier blanket is better, because nobody publishes data that would support it. What GSM does tell you is what you are buying in fabric terms, and it is one of the few numbers in this category that compares across brands. Light is also a real advantage if the blanket has to go in a cupboard for eight months of the year. The whole fabric ledger is on fleece, flannel, sherpa or plush.

The listing itself frames the low weight as a feature - a lightweight queen, easy to store. That is a fair description rather than a claim we need to check.

The wash and dry instruction, which is better than most

Westinghouse states the sequence: unplug the controller first, machine wash cold on gentle or hand wash, tumble dry on low or line dry, and do not use the blanket while wet.

A published drying rule is rarer than it should be. Of the makers we track, only Biddeford and Westinghouse name a drying method at all; Sealy names prohibitions without endorsing a dryer, and two brands say machine washable and stop. If the dryer question is what brought you here, the full disagreement is laid out on machine washable electric blankets and the step-by-step is on how to wash a heated blanket.

The warning Westinghouse prints that others do not

In the same bullet as the certification, the listing says: to extend product life, read the instructions and avoid folding or placing heavy objects on the heating wires.

That is unusually candid for listing copy, and it is also the single most useful sentence on the page. Folding and compression are exactly the conditions behind the failures we have documented in this category - trapped heat under a folded blanket, element insulation cracked along a permanent crease. Most makers keep that warning in the manual where you see it after you have bought. The detail is on what actually goes wrong and the storage version is on storing a heated blanket.

One controller, and whether that is a problem

The whole 84 x 90 inches runs at one temperature from one controller. If you share the bed with someone who runs hotter or colder than you, this blanket will end up set to whatever the colder person can tolerate, which usually satisfies neither.

If you sleep alone, it is the opposite: a second controller is a second cable run and a second thing to detach before washing, for a zone you will never use separately. That argument, with picks on both sides, is on dual control or single control.

Who should buy this, and who should not

  • Buy it if you want the lowest published running cost on a queen bed and you sleep alone or agree on temperature.
  • Buy it if you want the drying rule in writing. It is one of only two brands in our set that publishes one.
  • Buy something else if you want a warranty term. This listing states none, and Beautyrest and Sealy both state five years at the same size.
  • Buy something else if you share the bed and disagree about heat. One controller cannot be split - see dual control electric blankets.
  • Buy something else if you want a published temperature range. Westinghouse states none; the brands that do are ledgered on how hot does a heated blanket get.
  • Check the size line if you want a different size. The 100 W figure belongs to this queen listing and does not carry to the Westinghouse king.

The short version

A plain, light, well-specified queen that does the one thing this category mostly refuses to do: it tells you what it draws. 100 W is the lowest published figure of any bed blanket here, and it is the reason this blanket leads our energy-efficiency rankings despite publishing no temperature range and no warranty term. If what you want is a known cost on a bed you have to yourself, nothing else in our registry answers the question as directly.

Questions people actually ask

How many watts is the Westinghouse heated blanket?
100 W at 120 V, 60 Hz, stated in the first bullet of the queen listing. That is the whole blanket rather than one side, because it is a single-controller product, and it is the lowest published figure of any bed blanket we track.
What does the Westinghouse heated blanket cost to run?
At its published 100 W, about 15 cents for an eight-hour night at $0.1834/kWh, the US EIA average residential rate. That is a ceiling: the blanket cycles its element off once the bed is warm, so a real night costs less.
Does the Westinghouse heated blanket have a warranty?
The queen listing states no term, and the product's manufacturer record leaves the warranty field empty. Exactly one Westinghouse product in our registry states a term - the foot-pocket throw, at five years - and one more says a warranty is offered without naming a period.
Is the Westinghouse heated blanket dual control?
No. The queen ships with one controller for the whole bed. If two people need separate temperatures, this is the wrong blanket at this size.
Can you put the Westinghouse heated blanket in the dryer?
The listing says tumble dry on low or line dry, with the controller unplugged first, and that the blanket must not be used while wet. Westinghouse is one of only two makers in our set that publishes a drying method at all.
What size is the Westinghouse queen heated blanket?
84 by 90 inches, stated on the listing, in double-layer 200 GSM flannel. Against a 60 x 80 queen mattress that is about 24 inches of spare width for drape - the full size table is on heated blanket sizes.
