FAQ - Navien Mate - Heated Mattress Pad | Thermal Blanket for Bed

You can use drinking water or tap water instead of distilled water. We recommend using purified water as much as possible.

Remove the water according to the method of draining water from the heating unit and the mat, and store it according to the following method.

  1. Heating Unit
    Keep the heating unit dry in the shade, ventilated and out of direct sunlight. (It is recommended that you save the residual water removal kit and instructions together to prevent loss.)
  2. Mat
    If you do not use the Navien Mate, please spread the mat and keep it in a room as it is, or fold and keep it in a comfortable place according to your preference. The mat should be hand wash. If any stains are found, rub lightly, then wipe with a soft cloth. Use of washing machine is prohibited.
    ⋇ If you use the storage bag provided at the time of purchase, you can keep it clean and convenient.
  3. Cover
    The cover can be used as a bed pad throughout the year after being separated from the mat. The cover is 100% pure cotton. So please put it in the washing net and use the wool washing function to set the water temperature to “cold” and dehydrate. Please use a neutral detergent. When using a drum washing machine, please avoid high temperature and high temperature drying.

The sterilization mode will briefly boil the water in the heating unit and in the hose to quickly kill germs. We recommend doing this once a month. Do not lie on the bed warmer pad during sterilization mode.

Navien Mate conducts pre-inspections of all products before launch, but if there is a leakage problem on your product, discontinue use and contact Navien Mate Customer Service Center (  1-877-689-1541 ).

No harmful chemicals are used in the system. Especially, the Rawganic (Raw + Organic) mat cover is made by 100% organic material and free of dyes and chemicals

The connector guard prevents contact with hot components. When the heating unit is tipped, the balancing sensor automatically turns the system off and the overflow prevention filter prevents water spilling. The heating unit will automatically shut down after 15 hours of continuous use. When room temperature drops below 41°F, the system will automatically activate to prevent water from freezing in the system.

Refill time varies depending on the indoor environment (temperature and humidity) and customer use (temperature setting, hours of use, etc.). In general, if the system is set at 99°F and used for 8-10 hours per day. Water should be filled higher than medium level bars for continuous and safe heating. Do not overfill.

If the connection between the hose of the mat and the heating unit is incomplete, a water shortage error may occur. Or, the error may occur when you use distilled water. If so, test it with tap water please.

  1. Touch the hose connector bracket (white plastic case) of the mat to check warmth. If you can’t feel warm, combine the mat and hose connections until you hear “click” sound.
  2. If the cushion type mat is folded in the same shape for a long time, the hose may partially stick to each other, and then the water circulation may not be smooth. However, it can be restored naturally after 1 to 2 days of use. Please refer to Tip below to help restore hose faster.

⋇ Tip for faster hose restoration

  • Set the heating unit and mat to the same position horizontally and set to the maximum temperature.
  • Use the residual water removal kit provided when purchasing the product to inject air.
    1. Disconnect the connector from the boiler, then insert the kit.
    2. Insert the pump into the non-heating side and inject air about 10 times.

⋇ If you use other equipment, such as a bicycle pump, not supplied, and inject air, the mat may be damaged.

Because material of the Rawganic cover is 100% organic cotton, fine cotton seeds remain on the fabric. This is 100% natural, so it does not affect the softness, absorbency or texture of the fabric.
