Are waterbeds heated

Water beds promise a high level of sleeping comfort. They have a therapeutic effect, but they also have a major disadvantage: Because water cools down in the bedroom and, without the appropriate technology, can lead to uncomfortable nights. A waterbed heater, which transforms the comfortable mattress into a cozy hot water bottle, promises a remedy.

The function of the waterbed heating simply explained

The waterbed heating consists of heating mats that lie under the water mattress. In operation, the elements reach a temperature of up to 70 degrees Celsius, heating conventional water beds to between 25 and 36 degrees Celsius. You can conveniently select the temperature via a connected thermostat. Depending on the model, you also have the option of setting timers or alarm times.

Electric heating conductors provide heat for the waterbed

The water bed heater is an electric heater, which essentially consists of so-called heating resistors. These heat up immediately when voltage is applied. In contrast to central heating in the house, hardly any heat is lost. Because a water bed with heating takes up almost all of the energy from the heating mats. However, it is important that there is a free socket near the bed. Because this is where the heating system draws electrical energy.

Waterbed heating with mains isolation available

If the house electrical system is equipped with a mains isolation, a relay separates circuits without active consumers. This helps to save electricity and increases safety. If the waterbed heater is suitable for mains isolation, it has its own voltage source to enable electricity when required. Otherwise the electrical energy stays away and the waterbed with heating cools down.

The right temperature for heating in the water bed

The temperature to which the heater should heat your waterbed depends on your habits. Experts recommend around 26 degrees Celsius for the summer. In this way you ensure pleasantly cool nights without freezing. In winter, values ​​of 28 degrees Celsius are advisable. This temperature corresponds to the surface temperature of the skin. If the bed is warmer for a long time, the body begins to sweat in order to regulate its heat balance.

Different types of heating available

If you want to buy a waterbed with heating, you have the choice between carbon and ceramic heaters. Both are flat heating elements that lie under the water mattress. Carbon mats are usually larger. They give off heat evenly and quickly ensure a comfortable temperature. Smaller ceramic waterbed heaters, on the other hand, only heat the water selectively. It can take a little longer until all areas of the surface are comfortably warm.

How long does a waterbed heater actually last?

The electrical heating systems are maintenance-free and last at least ten to 15 years. Manufacturers give a two to five year guarantee. In this way, you are on the safe side in the event of damage occurring earlier, for example due to product defects.

How can I replace the heater in the waterbed?

Before replacing the water bed heater, you must pump out the water mattress. Once that's done, pull out the old mats and insert new ones. Then connect the heating to the mains and refill the water mattress. Even if the work is easy to do by hand, it takes some time to empty and fill the mattress.

The cost of heating for my water bed

A waterbed heater costs 50 to 250 euros. The amount of the expenditure depends on the type of heating elements, the performance and the range of functions. How much a waterbed with heating costs during operation also depends on the performance. Other influencing factors are the ambient temperatures and the desired bed temperatures.

An example: If the heater runs at 200 watts for one hour, it consumes 0.2 kilowatt hours of electricity. At a price of 0.3 euros per kilowatt hour, costs of 0.06 euros per hour are incurred. If the heating works continuously at a lower output, the costs are lower.

Better to leave the heating on the water bed switched on

To save energy, some waterbed owners switch off the heating during the day. Contrary to what was assumed, however, this is usually associated with higher power consumption. Because the bed cools down considerably during breaks in heating. In the evening, a high level of performance is required in order to achieve comfortable temperatures. It is more economical if you always leave the heating on. Because then it only has to compensate for the low heat losses and consumes less. If you are not at home for a longer period of time, however, you can switch off the waterbed heating or turn it down. In this case, you save electricity and money.

Conclusion by Alexander Rosenkranz

If you want to ensure healthy sleep with a water bed, you also need a water bed heater. Because this brings the otherwise much too cold water in the mattress to comfortable temperatures. Systems made of carbon or ceramic are available that can be conveniently operated on the thermostat.
