Descrizione
Heat Is a Design Problem, Not a Season. Air conditioning cools a room, and then spends the night fighting the air it just cooled: open doors, west-facing glass, a body producing its own heat under a duvet. The result is a cold room and a warm sleeper, which is the least efficient way to spend electricity. Cooling the surface a person actually lies on is a different engineering problem with a much shorter distance to travel. Water carries heat far better than air, and a circulating loop moves it away from the body instead of trying to chill the volume of the room.
This is the machine half of that idea. A blower and pump unit sits beside the bed and circulates cooled water through the mattress pad, so heat leaves through conduction rather than convection. It runs on AC mains, carries CE certification, and ships with EU, US and BS plug adapters so the unit powers up on the first night wherever the bed is. A humidifier function lets the same airflow add moisture to dry, air-conditioned air. Priming is straightforward: the manufacturer documents roughly two minutes of circulation before the water reaches a single-size mattress pad, and about four minutes for a double-size pad, after which the loop runs quietly in the background.
The pad itself is the part that touches the person, so it is the part that matters: a soft mattress topper fed by flexible tubing, cool to the touch within minutes of switching on. Use it in a bedroom with no air conditioning, in a workshop office where the sun lands all afternoon, in a camper or boat cabin that turns into an oven in July, in a guest room occupied two weeks a year, or beside a desk where a person sits still for eight hours in the heat. Keep the reservoir topped up, drain the loop before storage, and it becomes the appliance that makes a hot room survivable without cooling the whole building.
Air moves heat slowly. Water moves it now.
Key Features
- ✦ Water-circulation cooling for a mattress pad, cooling the sleeping surface instead of the room volume
- ✦ Mains AC power with CE certification and EU, US and BS plug adapters supplied
- ✦ Humidifier function to add moisture to dry, air-conditioned rooms
- ✦ Single-size mattress pad included, with pad and tubing connected to the blower unit
- ✦ Manufacturer-documented priming time of about two minutes for a single pad and four minutes for a double pad
- ✦ Circulates continuously once primed, so the surface stays cool through the night
- ✦ Independent of building air conditioning, useful where cooling a room is impractical
- ✦ Compact enough to stand beside a bed, a desk or a cabin bunk

Where It Belongs
This system belongs to any room where a person has to sleep or work and the building cannot be cooled effectively. Bedrooms in rented flats without air conditioning, where a portable unit would be noisy and expensive to run. Attic and west-facing rooms that hold heat long after sunset. Camper vans, narrowboats and truck cabs, where there is no second room to cool. Workshops and home offices with a desk under a skylight. Guest rooms that sit empty for most of the year and cannot justify a full cooling installation. Hospitals and care settings where a patient cannot regulate their own temperature. The logic is the same in every case: cool the person, not the building.
Frequently Asked Questions
Q: Do I need to add ice to the unit?
The unit circulates water through the pad to move heat away from the surface. Fill the reservoir as instructed before the first use and keep it topped up during operation.
Q: How long until the pad feels cool?
The manufacturer documents roughly two minutes for the water to circulate out through a single-size mattress and about four minutes for a double-size pad.
Q: Will it work on a double bed?
This configuration ships with the single-size mattress pad, and the manufacturer documents the priming time for double-size pads as well. Check the pad size against your mattress before ordering if you need the larger format.
Q: What plug does it arrive with?
EU, US and BS plug adapters are provided with the unit, so it can be powered in the common socket standards without a separate travel adapter.
Q: Does it also humidify the room?
Yes. A humidifier function is part of the unit, which helps in rooms where air conditioning or dry heat has stripped moisture out of the air.
Q: How should I store it at the end of the season?
Drain the water loop, let the pad and tubing dry fully, and store the unit flat with the tubing coiled loosely to avoid kinks.
