What is the optimal temperature of a warm water floor and coolant??

Achieving the ideal temperature for the coolant and heated water when installing a warm water floor heating system is essential for comfort and efficiency. The way the system warms up a room, how much energy it uses, and how well it works are all greatly impacted by the temperature settings.

The ideal temperature range for heated water in warm water floor systems is usually between 38°C and 54°C, or 100°F and 130°F. With this range, you can be sure that the water is hot enough to heat the floor surface efficiently and without using too much energy. While lower temperatures might not offer enough warmth, higher temperatures might result in needless energy use.

Maintaining the performance of the system also heavily depends on the coolant selection, which is typically a mixture of water and glycol to prevent freezing. To ensure effective heat transfer throughout the system, the coolant mix’s ideal temperature is often close to that of the heated water. By preventing overheating or underheating, this balance maximizes energy efficiency while maintaining comfort.

Room size, insulation thickness, and weather conditions are just a few of the variables you must balance in order to determine and set the ideal temperatures for your warm water floor system. Through precise adjustment of these parameters, homeowners can optimize energy efficiency, create a cozy indoor atmosphere, and extend the life of their heating system.

What sensors are used?

The following kinds of sensors are utilized in order to continuously monitor the heated floor’s temperature:

1. Remote. They are distinguished by wide functionality, as well as reliable technical characteristics that allow you to monitor the thermal performance of heating as efficiently as possible. Such devices will be installed in close proximity to the thermostat, or in the same block with it.
2. Domestic. Their installation is carried out in such a way as to minimize the influence of external factors on the final performance of the sensors. The device looks like a small polymer cylinder.

When you require precise control over the heated floor’s temperature, two sensors—internal and external—are frequently used in tandem.

The first is intended to measure the pipeline system’s temperature indicators continuously, while the second is meant to keep an eye on the state of the floor covering.

Using them together allows for the most accurate temperature readings.

What should be the optimal?

GOST 30494-96 "Residential and public buildings" specifies the ideal temperature indicators for various kinds of establishments. parameters of the indoor microclimate. The following details are contained in this regulatory document:

1. In living rooms, a comfortable temperature for living should be from 20 to 22 degrees Celsius.
2. In the kitchen and toilet it is necessary to ensure the temperature within 19-21 degrees Celsius.
3. In the bathroom or combined bathroom, it is recommended to maintain a temperature of 24 to 26 degrees Celsius.
4. The microclimate in the corridor should be ensured at 18-20 degrees Celsius.

For the comfort of the feet and the aforementioned indicators, a warm water floor should be between 27 and 28 degrees.

It can be raised to 31 degrees if nobody is in the room very often. The most important thing is that it offers the aforementioned professional advice regarding the temperature indicators of various types of rooms.

Valid values

It is advisable to concentrate on the allowable values rather than the limit values when calculating the temperature of a water-heated floor system, as these are typically simple to reach. A minimum floor temperature of minus 26 degrees Celsius is acceptable. A maximum of 35 degrees Celsius is allowed.

It’s critical to understand the following temperature specifications for spaces with heated flooring:

1. In rooms intended for human habitation, the permissible temperature can range from 18 to 24 degrees Celsius.
2. In the kitchen, experts advise creating a microclimate with temperatures ranging from 18 to 26 degrees Celsius.
3. In a toilet, bathroom or combined bathroom, the permissible temperature can range from 18 to 26 degrees Celsius.
4. Slightly lower temperatures are acceptable in the corridor – from 16 to 22 degrees Celsius.
5. In the lobby or stairwell, in accordance with the law, the permissible temperature should be between 14 and 20 degrees Celsius.
6. In the pantry it is necessary to ensure an acceptable temperature regime that does not go beyond 12-22 degrees Celsius.

The aforementioned suggestions enable the creation of suitable living environments for humans in particular categories of buildings that vary primarily in their intended use and purpose.

Coolant

The majority of the time, it is sufficient to provide the heated floor system with coolant, which should have a temperature between 50 and 70 degrees.

By using these indicators, it is possible to guarantee that the floor covering’s heating does not go above ideal levels. Consequently, any harm to the materials—tiles, carpet, linoleum, parquet, etc.—can be avoided.

When selecting the water or other liquid temperature to be supplied to the heated floor, consideration should be given to the following factors:

• type of screed and its thickness;
• features of the operation of the premises;
• availability of additional heating;
• type of flooring;
• purpose of the room, etc. d.
• desired room temperature

After the system has been tested for several hours, the coolant temperature needs to be regulated.

Standards for underfloor heating under final coating

A room’s heated floor system must be properly installed by paying attention to specific state temperature standards beneath the final coating. These are outlined in the following regulatory laws that are in effect within the Russian Federation:

• SNiP41-01-2003 “Heating, ventilation and air conditioning”;
• GOST 30494-96 “Residential and public buildings. Indoor microclimate parameters".

Consequently, in the event that the decision has been made to implement a water-heated floor system, consideration must be given to the guidelines outlined in the aforementioned legislative acts.

For underfloor heating systems to function effectively and provide comfort in any home, the warm water passing through the pipes and the coolant circulating within the system must be at the ideal temperature balance. The optimal temperature settings for the coolant and the warm water are examined in this article, taking into account variables like system longevity, thermal comfort, and energy efficiency. Homeowners and builders can make wise decisions to guarantee that their underfloor heating systems operate at peak efficiency all year long by being aware of these settings and their effects.

Maximum

The highest temperature that should be achieved is 27 degrees Celsius. This regulation solely pertains to properties where individuals live on a permanent basis.

The following maximum heating temperatures for heated floors should be noted: based on the flooring materials chosen:

1. If laminate or parquet is laid on the floor, it is not recommended to heat the coolant to more than 27 degrees Celsius.
2. In most cases, when using tiles, the heated floor can be heated to 28-33 degrees Celsius. In this case, the type of screed, features of the operation of the room, etc. play an extremely important role.d.

1. If carpet is used, the coolant may have a temperature of up to 27 degrees Celsius.
2. Under linoleum, a warm floor can be heated to no more than 26 degrees Celsius.
3. If there is varnish on the surface of the floor covering, the heating temperature of the heated floor system should not exceed 21 degrees Celsius.

Controlling the heating temperature of a heated floor system is therefore crucial when using one.

Minimum

People’s comfort in a given room is directly impacted by the floor’s temperature. Their health is also impacted by this. Because of this, professionals advise against lowering floor temperatures below the following ranges:

1. In living rooms – below 18 degrees Celsius.
2. In the kitchen – below 18 degrees Celsius.
3. In the toilet – below 18 degrees Celsius.
4. In the combined toilet or bathroom – below 18 degrees Celsius.
5. In the corridor – below 16 degrees Celsius.

1. In the lobby or on the stairwell – below 14 degrees Celsius.
2. In the storage room – below 12 degrees Celsius.

Therefore, it is imperative to guarantee that the temperature regime in each of the aforementioned rooms is higher than the indicators listed.

What is the floor’s freezing point? The coolant temperature must be kept above freezing if water flows through the pipes; otherwise, the pipes will just freeze. If you use antifreeze as a coolant, you can be comfortable in temperatures as low as -65 degrees Celsius. This is the best option.

The ideal temperature for a warm water floor and its coolant must be selected for your home’s comfort and effectiveness. For the floor surface, the recommended ideal temperature range is normally 25°C to 29°C (77°F to 84°F). The floor will be comfortably warm underfoot without being overly hot or uncomfortable thanks to this range.

The temperature of the coolant that circulates through the system, such as water or a mixture of water and glycol, is normally set slightly higher, usually between 35°C and 45°C (95°F and 113°F). This increased temperature guarantees that the coolant returns to the heating source at a temperature that is warm enough to sustain efficiency while enabling the system to transfer heat to the floor surface efficiently.

It is significant to remember that these temperature ranges can change depending on things like the kind of flooring that is put over the system, the room’s insulation, and the climate where you live. To find the most comfortable and energy-efficient settings for your particular setup, adjustments might be necessary.

To make sure your warm water floor system keeps working properly, regular upkeep and observation are necessary. This entails monitoring and modifying the temperature settings according to the season and looking for leaks or other issues with the system that might affect how well it works.
