First, decide by place.
On the bed, an electric mattress pad; on the floor, a heated carpet. The pad goes on a futon or mattress with the sheet over it, so it does not touch the skin directly. A heated carpet is spread on a hard, flat floor where you sit or rest your feet.
A heated carpet cannot be used on a bed, a sofa or anything soft that sinks. Do not sleep or doze on a heated carpet.
Check the area in cm.
Rooms in Taiwan are often measured in ping, but for a heated carpet it is more reliable to check the place in cm. The sizes of the JPHEAT models, where each is used, and the Taiwan price (shipping included):
- Single electric mattress pad JPT100J: about 190×100 cm. Full body, on a single mattress or futon. NT$7,150
- Half electric mattress pad JPT7080J: about 70×80 cm. For part of the bed, such as the back, hips or feet. NT$4,200
- Under-desk foot mat JPT5060: 50×60 cm. Under the desk or at your feet. NT$2,850
- One-person heated carpet JPT60100: 60×100 cm. One person’s seat, or the feet in front of a sofa or chair. NT$4,300
- Sofa-front heated carpet JPT16060: 160×60 cm. Long, along the front of a sofa. NT$5,800
- Living-room heated carpet JPT200120: 200×120 cm (about 2.4 m², 0.7 ping). The living room. NT$15,000
Check the power supply.
JPHEAT electric mattress pads run on low-voltage DC 24 V through the supplied dedicated adapter (input AC 100–240 V), plugged straight into a Taiwan household outlet (AC 110 V). The heated carpets sold in Taiwan are AC 110 V, 60 Hz Taiwan versions. Every model carries the BSMI commodity safety label.
Other regions get their own versions (AC 100 V in Japan and AC 220 V in Hong Kong and Macau, for example); for use in Taiwan, go by the specifications on the Taiwan pages.
Temperature and timer.
Every JPHEAT model sets the temperature from 20 to 50 °C, 1 °C per press. The off timer runs 1–12 hours; setting it to 00 cancels the timer, and the unit stays on until you switch it off. On the heated carpets the timer is set to about 8 hours by default.
Use the off timer when using a pad at bedtime, and switch the unit off when not in use.
Start low, use safely.
Start at a lower temperature and find the one that suits you. As a guide, 38 °C for the heated carpets, and 30–38 °C for long use of an electric mattress pad. Long contact with the same spot can cause low-temperature burns even at a low setting. When small children, older people or anyone less sensitive to heat use it, stay close by.
Insulation and care.
Some heated carpets ask you to lay an insulation or foil sheet underneath. JPHEAT heated carpets have an insulation layer built into the back, so no separate sheet is needed. The surface is splash-resistant PVC, but not waterproof, so it cannot be washed in water.
The pads cannot be machine-washed either. For both, switch off, unplug, and wipe with a well-wrung cloth. Fold a pad for storage only after it has cooled.
Buying in Taiwan.
The Taiwan site lists prices in NT$ with shipping included. Orders leave our Asia-Pacific warehouse (Shanghai, China) within 3 business days and arrive in about 7–10 days. As a cross-border purchase there is no trial and no returns or exchanges for personal reasons; an initial defect, damage in transit or a wrong item is exchanged at our cost. The warranty is 1 year, under the terms of the warranty card.
Questions and answers
How do I choose between an electric mattress pad and a heated carpet?
On the bed, under the sheet: an electric mattress pad. Spread on the floor where you sit or rest your feet: a heated carpet. A heated carpet cannot be used on a bed or sofa, and you should not sleep on it.
How does an electric blanket differ from an electric mattress pad?
An electric blanket is usually a blanket you put over or under you; an electric mattress pad goes on a futon or mattress with the sheet over it.
What size heated carpet suits one person?
For under the desk or the feet only, 50×60 cm; to warm one person sitting on the floor, 60×100 cm.
What size goes in front of a sofa?
Laid long along the sofa, 160×60 cm; covering the area from the sofa to the coffee table, 200×120 cm (about 0.7 ping). Measure the sofa width and the depth where your feet go first.
Do I need a voltage converter in Taiwan?
No. The heated carpets are Taiwan AC 110 V versions, and the pads come with a dedicated adapter (input AC 100–240 V, output DC 24 V) that plugs straight into a Taiwan household outlet.
What happens if the off timer is set to 00?
The timer is cancelled and the unit stays on until you switch it off. On the heated carpets the timer is set to about 8 hours by default. Switch it off when not in use.
Does a heated carpet need an insulation sheet?
No. JPHEAT heated carpets have an insulation layer built into the back, so no separate sheet is needed. Use them on a hard, flat floor.
