According to the instructions, underfloor heating is not recommended for installation under heavy furniture or appliances. Underfloor heating under furniture is generally unnecessary; it will only lead to additional heat loss, resulting in increased financial costs, and will also reduce the heating efficiency.
If furniture or equipment is placed on a heating surface, it must have legs (at least 5 cm) so that warm air can circulate freely.
Otherwise, the surface and the device itself will overheat, leading to its rapid failure.
How does underfloor heating affect a refrigerator?
Most refrigerators have a compressor located at the bottom, and high ambient temperatures will force the motor to run longer and with short breaks. Therefore, the question arises: how to properly install the refrigerator and how to insulate it from the warm air flow.
It's worth noting that these refrigerators are designed to cool down even when overheated. They're also designed for use in very hot countries, so they can operate when the ambient temperature reaches 45°C.
Of course, increasing the load on the motor will cause it to overheat, but this is unlikely to cause failure, although it will shorten its service life. However, if possible, it's best to avoid installing bulky appliances directly on a heat source.
Water floor
Many people will say no to the question of whether it's possible to install a refrigerator on a water-heated floor. When the heating system in the kitchen is already installed and there's no desire to remove the screed, many people install it in the hallway rather than the kitchen for fear of damaging the unit.
However, compressors have the ability to cool down when heated, and the equipment itself is equipped with excellent thermal insulation, so heating will not cause significant damage to the device.
In addition, if the settings are made correctly, the surface heats up no higher than 27 - 29 °C, and this is the natural temperature of the floor covering in summer.
Cable floors
Is it possible to install a heated cable floor under a refrigerator or freezer? It is not recommended, but it is acceptable when installed in a screed.
As already mentioned, a heating device cannot negatively affect the freezer, but it is better if the equipment is installed on legs, in this case, air circulation will be unimpeded.
Infrared floors
It is not recommended to install infrared (film or rod) models under the refrigerator.
But if there's no other way out, this statement can be ignored. All units have overheating protection.
The effect of a refrigerator on underfloor heating
We've already established that heated floors don't cause significant damage to refrigerators, so let's explore how refrigeration equipment affects underfloor heating.
After all, this type of heating has its own operating rules: heavy objects cannot be placed on most types, and a refrigerator is one of them.
Water floor
Water heating is often poured into the screed, so it can be installed throughout the entire room, without taking into account the arrangement of furniture.
Since the concrete layer provides excellent protection for the heating elements from mechanical stress, heavy household appliances or other bulky objects can be placed on the concrete-embedded pipeline without causing any damage.
However, it's worth noting that combining hydronic underfloor heating and a refrigerator in an apartment is not possible, as installing hydronic floors in apartment buildings is prohibited.
Electric cable floors
Heating cables or mats are the most common type installed in apartments. If the cables or mats are laid in the screed, refrigeration equipment will not negatively affect the heater; this provides the most reliable protection against overload caused by heavy objects.
But in apartments, heaters are often installed without a tie, which leads to point loads on the cable. And in places where the appliance puts pressure on the cable, it will overheat. This will lead to burnout of the elements, thereby causing the heating device to fail, which will happen faster than the refrigeration unit.
Cable mats are more cost-effective because if one element fails, the entire heated floor will continue to function.
Infrared systems
Standard film floor When the temperature exceeds this limit, it begins to melt and fails. The answer to the question of whether it's safe to place film under a refrigerator is a clear no, as this will cause overheating in that area.
Therefore, it's important to mark the locations where you'll be placing appliances and furniture in advance. However, it's worth noting a significant advantage of the film: if one component of the device fails due to overheating, the entire structure will continue to function.
There's a self-regulating type of film; this model can adjust power and heat output when heated above 60 degrees Celsius. This heating film is resistant to overheating under heavy objects and can automatically reduce power. However, even this type is not recommended for long-term installation under the unit, as this will reduce its service life.
A rod floor is an infrared type, made of heat-resistant carbon rods. Unlike film heating, rod heating can accommodate large items and even a refrigerator, thanks to its self-regulating properties.
Carbon reduces heat buildup under equipment while continuing to distribute heat evenly in open spaces. Furthermore, such systems are often installed in a concrete slab, which protects the device from overheating.
Features of installing a freezer on heated floors
The function of a freezer is to provide cold. Operating a stationary industrial refrigerator can cause freezing and frost heaving of the ground, which can lead to foundation damage, especially in winter. To prevent this, it's important to properly create a cold barrier.
Can a freezer be installed on a heated floor? Yes, the heater will help prevent the ground from freezing. However, heated floors for industrial freezers differ in design from standard heated floors.
In this case, the heating element is placed under the insulating layer, which ensures that the heat is directed towards the ground, not the room.
Let's sum it up
To summarize, when installing a refrigerator on underfloor heating, you need to be more concerned about the heating element than the appliance itself. After all, the unit is protected against excessive heat, and in extreme cases, you can supplement this protection with a thermal insulating pad placed between the heating surface and the refrigerator, although this will not look aesthetically pleasing.
The only protection for heated floors is a concrete screed. Without one, overheating in the area where the refrigeration equipment is located is inevitable.
Therefore, if you have thought through the kitchen design before installing the heating system, then you have a chance to do everything according to the instructions and install both the refrigerator and the furniture according to the rules.
We have a refrigerator and a dishwasher and everything is fine.
