a mucho developed nation South Korea is, but with distinct four Seasons with freezing Winter : domestic electricity gets quite expensive in Winter (residence nested above multi-purpose buildings with business operating, get a big break though). and electric blankets or rather mattress as many still sleep on floors, are big sellers here . but with more advertisements on how radio-electric waves emitted can cause cancer – with still has no scientific evidence but I can atest to this as my dear old cat who slept all-day and night on a small one intended for chair seats : got a lump which tested positive but Thank God got cured after cutting if off – electrically water-heated mattress began coming out .
only a year ago the latter cost over W200,000 ~ 300,000 but price came down to half beginning this year due to buyers’ larger concerns . even in this category there are types that circulate water electrically, which makes sound even low . then there are those which does without :
here the latest 2015 model from the most popular seller in this field, just introduced this September for around W145,000 at larger On-Line discount outlets (single-size cost the same as double or queen): with separate temperature controls for left and right side . even includes a dedicated cover with calm floral design .
introduced before : ilWol Mat has been making this kind of very product from 2006, and before introducing this water-heated models, have been manufacturing electric mattresses with various kinds natural rocks long-familiar to this old culture – many used on spa saunas and retreats .
– soon to hibernate, Korea Tech BLog –
( One Week User Review ) I am not a mellow person in need of over-heating, but after a cozy night in an electric blanket with Chinese stones in Hangzhou : got one on return by Winter 2009 . then with electro-magnetic wave scare on cancer, thanks to perhaps another marketing ploy recurring on advertisements and home shopping channels on Cable TV : exchanged to a weaker one in 2012 which was the trend . but as more scare was on-air and witnessing our dear cat having cancer-positive mole after linger on not an all-out blanket but cushion for two Winters : got the water-heating model – and one without motor to pump – whose price had dropped to an affordable W100,000 mark . all manufacturers ilWol, the most popular and best-selling brand in its category year-after-year .
simply plugging-in an electric blanket was easy before, but now this one with water-hoses : you had to read its set-up instruction manual . first they caution several points, understandably as you can be electricuted if water leaks into the main heater :
- do not fold the mattress sharply as to dent the water tubes inside,
- halt if you puncture holes into the mattress,
- do not let a heater near the heater module,
- the heater model does leak weak electro-magnetic signals so keep it at least 30cm away from your body -_- duh
you expected it from seeing the product photo : but the heater module is indeed quite larger than the controls you are used to on an electric blanket . first connect the hoses into it, and pouring water into it was the art-part of this new ritual . ofcourse you have to hold the heater module higher than the mattress, and it takes about 1 liter of water . the manual says to pour water until it stops beeping, then additional half-cup but to leave a bit of room before over-flowing . after that it does not matter whether you keep the heater module above, at level or below the mattress . and as you would expect : the heat is considerably less than a all-out electric blanket but quite soothing . I did get a headache in the morning the first two days though ..
