How the AquaPad works

The system

Warmth you can feel, engineered to stay out of the way.

What actually heats the bed in an AquaPad?

A bedside control unit heats water to your chosen temperature and pumps it through soft silicone channels sewn into the pad. The pad holds only warm water — the electronics and heating element stay off the bed entirely.

  1. 1

    The control unit

    A quiet bedside unit heats and circulates the water, holding your set temperature within a tight band all night.

  2. 2

    The dual-tank reservoir

    Two chambers keep a steady volume of water moving so the temperature you feel is even from edge to edge.

  3. 3

    The pad

    Soft channels carry warm water just beneath a machine-washable cover — the only thing between you and the warmth is fabric.

What is in the box

  • Control unit — heats the water, pumps it, and holds your set point. Every electronic part in the system lives in this box, beside the bed.
  • Dual-tank reservoir — two chambers keep a steady volume moving, so the temperature you feel is the same at the edge as in the middle.
  • The pad — a silicone tube under 0.2 in across, routed between two foam layers under a machine-washable cover.
  • Tubing — two soft lines between the unit and the pad, carrying warm water and nothing else.

Temperature stability

Holds your set point without the overshoot-and-crash cycle of electric coils

Does the water ever touch me or the mattress?

No. The water stays sealed inside the pad's channels and the tubing at all times. You feel warmth through the cover, and the mattress underneath stays dry — the closed loop never opens onto the bed.
