Electric blanket questions

What is a far-infrared electric blanket?

Infrared is light with a longer wavelength than visible light. Anything with a temperature gives off infrared, and the longer-wavelength part is usually called far infrared; it cannot be seen. JPHEAT underblankets and heated carpets use no heating wire: ORIZUMI, a flat heating element made from water-based carbon, gives off its warmth as a flat surface rather than a wire.

What should I compare when choosing an electric blanket?

Start with size and where it goes. For the bed there is the single JPT100J (about 190 × 100 cm) and the half-size JPT7080J (about 70 × 80 cm, for the upper body, middle or foot end). For the floor, heated carpets come in 50 × 60, 60 × 100, 160 × 60 and 200 × 120 cm. Then compare voltage and plug, temperature range, auto-off timer, cleaning and repair cover. Every JPHEAT model sets 20–50 °C in 1 °C steps, has a 1–12 hour auto-off timer and 1 year of repair cover.

How does a DC 24 V low-voltage heated pad work?

The JPT100J and JPT7080J run on low voltage: the dedicated adaptor turns the AC 220 V from your socket into 24 V direct current, so the pad and its heating element run on 24 V DC. The adaptor input is AC 100–240 V. The pad is not battery-powered, so the adaptor stays plugged in while you use it.

What should I keep in mind when using an electric blanket?

Lay the underblanket flat on the mattress with a sheet over it; never wrap it around you or cover yourself with it, and never switch it on while folded, overlapped or creased. Begin at a lower temperature; for long use of an underblanket, 30–38 °C is a guide. Low-temperature burns can occur even at fairly low settings if one spot stays warm for a long time, so change position now and then. A young child, an older person or anyone who finds heat hard to sense should use it with someone close by. Read the safety section of the manual before use.

Can I leave it on all night?

JPHEAT underblankets have a 1–12 hour auto-off timer. At night, use a lower temperature with the timer so it switches off once you have dozed off and one spot is not warmed all night. Heated carpets are floor products; do not use one as a bed.

Do I need a separate adaptor or plug in Hong Kong?

No. The heated carpets are AC 220 V versions for Hong Kong and Macau, and the underblankets run from their dedicated adaptor (input AC 100–240 V). Every product comes with a UK 3-pin plug adaptor.

How much electricity does a heated carpet use?

Estimate it as power (kW) × hours of use. At rated power for one hour: JPT5060 (80 W) about 0.08 kWh, JPT60100 (200 W) about 0.2 kWh, JPT16060 (350 W) about 0.35 kWh, JPT200120 (800 W) about 0.8 kWh. Actual use depends on the temperature setting and the room; the charge depends on your electricity plan.

Can an underblanket or heated carpet be washed?

No current model can be washed whole or in water. For marks, switch off, unplug and wipe with a well-wrung cloth. The heated carpets have a PVC top with everyday water-repellent treatment.

How long does delivery to Hong Kong and Macau take, and is it charged?

Orders leave our Asia-Pacific warehouse (Shanghai, China) by SF Express within 3 working days and reach Hong Kong or Macau in about 5–7 days. Prices on each product page are in HK$ with delivery included, so there is no delivery fee at checkout.
