When choosing,
and when using.

Heated floor mats and electric blankets generally have heater wire (a line-shaped heating element) laid through them. All JPHEAT products now available use ORIZUMI, a planar heating element with no heater wire. The woven water-based carbon mesh itself heats when powered, making heat from a single surface (Japanese Utility Model Registration No. 3241937 and No. 3241938). How planar heating and far infrared work is explained on the Technology page.

The JPHEAT heated mattress pads JPT100J and JPT7080J are low-voltage products: the included dedicated AC adapter converts power from a household outlet (AC 100 V) to 24 V DC before sending it to the pad. The pad and the planar heating element carry nothing but 24 V DC. It is not rechargeable, so please keep the adapter plugged into the outlet during use.

No. JPHEAT heated floor mats (JPT5060, JPT60100, JPT16060, JPT200120) have an insulation layer built into the back, so you can spread them straight on the floor without a separately sold insulating underlay or aluminum mat underneath. Please use them on a hard, flat floor.

An electric blanket is a blanket-type product that goes over or under you. The JPHEAT heated mattress pad is laid on a futon or mattress with a sheet on top, and instead of heater wire, the ORIZUMI planar heating element heats as a surface. Temperature can be set within 20–50 °C in 1 °C steps. When sleeping, please use the off timer (1–12 hours) and a lower temperature.

The structure of the heating element differs. Ordinary heated floor mats heat with heater wire laid through them, while JPHEAT uses ORIZUMI, a planar heating element of woven water-based carbon mesh, so the surface itself is the heating element. In third-party testing, a test sample of the JPT100J measured a peak wavelength of 8.35 μm and a normal total emissivity of 0.89. These are results for the test sample and do not indicate the surface temperature of each product or any action on the human body.

The JPT200120 covers 2.4 m², about the same as a mat generally sold as “for 1.5 tatami” (about 176×128 cm, about 2.25 m²). It is large enough to cover from the front of the sofa to a low table, with a rated power consumption of 800 W. 50×60 cm (JPT5060) is for under a desk or at your feet, 60×100 cm (JPT60100) is for one person, and 160×60 cm (JPT16060) is a long size laid in front of the sofa.

As a guide, the electricity cost is “power consumption (kW) × hours of use (h) × electricity rate.” At ¥31/kWh (the guideline rate of the Nationwide Association of Fair Trade Conference for Home Electric Appliances), 1 hour at maximum output costs about ¥2.5 for the JPT5060 (80 W), about ¥6.2 for the JPT60100 (200 W), about ¥10.9 for the JPT16060 (350 W) and about ¥24.8 for the JPT200120 (800 W). Power is reduced once the set temperature is reached, so the actual cost is generally lower. It varies with the rate in your contract.

The surface is PVC with an everyday water-repellent finish, so you can use it as is, without a cover. Spills can be wiped off with a well-wrung cloth. If you lay a rug or similar on top, choose a thin one so heat does not build up. There is no dust-mite mode.

Products now available are designed for use by people. Do not use them for purposes other than those intended, such as warming pets. A heated pet mat is coming soon as a separate series.

All heated mattress pads and heated floor mats now available can be set within 20–50 °C in 1 °C steps. Instead of high, medium and low settings, you set the temperature you like as a number. The off timer is 1–12 hours. The display shows the set temperature. The actual surface temperature and how warm it feels vary with the environment, such as room temperature, rugs and bedding. Start at a lower temperature.

Start at a lower temperature and find the one that suits you. As a guide, set heated floor mats to 38 °C, and heated mattress pads to 30–38 °C for long use. Warming the same spot for a long time can cause low-temperature burns, even at relatively low temperatures. Change your position or the position of the product from time to time. When an infant, an elderly person or anyone who has trouble feeling heat uses it, a guardian or caregiver should watch over them. Heated floor mats are products for the floor. Do not use them for sleeping or napping, and turn the power off when you go out. Lay the heated mattress pad under the sheet when using it. Before use, always read the included instruction manual.

The instruction manual, in Japanese, is included with the product. If you want to check it before purchase or do not have it at hand, please contact us with the model number.

None of the products now available can be soaked or washed in water. To clean off dirt, turn off the power, unplug it and wipe with a well-wrung cloth. Storage differs by model, so please check the included instruction manual.

Conditions of use differ by model. Heated floor mats are laid on the floor and cannot be used for sleeping. Lay the heated mattress pad on a futon or mattress with a sheet on top. For suitable flooring, placing furniture and similar points, please check the included instruction manual.
