FAQ
What is the problem with a hydraulically unbalanced system?
In an unbalanced heating or cooling system, not achieving the desired internal thermal comfort is caused by the uneven distribution of the heating or cooling in the spaces.
What do we achieve with a balanced system?
The positive effects of a hydraulically balanced system are the thermal comfort it offers to all users, the elimination of noise into the system, and the improvement of energy efficiency. Balancing valves manage the appropriate flow in each branch of the network in accordance with the original study.
Does hydraulic balancing save energy?
Night pauses save energy. However, the requirement for full load conditions in the morning fully activates all room thermostats. In unbalanced installations, the remote circuits are delayed or fail to have their rated supply until the room thermostats in the most beneficial circuits stop the flow after they have identified that the set point has been reached. Meanwhile, tenants of all the remote-powered apartments do not enjoy the thermal comfort that they have paid for.
Many apartments or rooms reach the desired temperature at noon, some not before noon and some never. This beginning process does not provide the occupants with the desired temperature. It can also increase heating costs for homeowners and tenants and it can lead to disputes between them.
How can the balancing valves be adjusted?
The adjustment of the valves to achieve the balancing of the installation can be done by using hydraulic panels or by a more precise procedure; using the tool of measurement and regulation of differential pressure of STH.
What types of balancing valves are there?
There are static balancing valves and dynamic balancing valves.
What are the advantages of a dynamic balancing valve compared to a static balancing valve?
The dynamic valve can be self-regulating through a membrane, keeping the initial setting (flow, differential pressure or temperature) constant, adapted to the network pressure changes. For this reason, its function is much simpler and faster while it allows a more flexible installation as well.
How do we convert a dynamic balancing valve to a control valve?
By integrating an electrothermal head into the valve, we combine hydraulic balancing and flow control in the same valve.
Is it a problem if condensate drops fall on the STH electrothermal valve?
No, it is not a problem, because the STH electrothermal valve involves protection IP54, which protects it from water drops.
Can a well-balanced system help us avoid legionella disease problems?
Yes. By having the whole installation at a consistent and constant temperature, we can avoid having a point where the temperature is below 45º, i.e., the temperature point at which legionella bacteria can grow.

What is a floor heating system?
It is a system formed by circuits of pipes that are integrated in the house's floor, and thus do not take up space into the house. This system, through water, transmits the required heat by radiation. The temperature it provides is homogeneous as these piping circuits are evenly distributed throughout the house.
What are the floor temperatures?
The maximum temperature of the floor surface reaches the maximum in normal circumstances acceptable value (29ºC for residential areas and 35ºC for perimeter zones next to external walls and openings).
Is it possible to install a radiator and an underfloor heating system at the same house?
Yes, we provide the opportunity of installing a mixed underfloor heating system with radiators, as long as we control the water temperature of the floor heating separately through a manual mixing valve or a mixing valve with a servomotor.
I want to install a floor heating system. What should I consider?
It is necessary to take into account that the final floor will rise a few centimeters in height compared to a heating installation with radiator. On the final finished outcome, the floor will rise at least 7-10 cm. In addition, it is necessary to have a set of thermostats in the rooms via cable or wireless as well as a place in the center of the house where the circuit breaker will be located. In the boiler room, there must be space for the connection of the mixing valve and a separate circulator, in case the boiler itself does not integrate them.
What is maximum operating temperature and pressure that the system with BetaPex pipes withstand?
According to UNE-EN ISO 15878, PE-X pipes must withstand at least 10 bar at 20ºC.
How many circuits can an underfloor heating collector have at most?
The maximum number of circuits is 12 per collector. Also all circuits should not exceed 100m.
What is the maximum power that can be achieved with floor heating instalation?
The maximum power that can be achieved is 100 W / m2 under normal conditions, which implies a floor temperature of 29 ºC. This efficiency is more than adequate in home installations with good thermal insulation. In fact, in some cases it could even exceed this performance.
Is it possible the heating power of 100 W / m2 to be exceeded?
In the bathroom and the perimeter of the floor, we can reach higher floor temperatures, and therefore a power of 140 W / m2 can be reached.
When to put anti-moisture film?
The anti-moisture membrane prevents the water that may be under the heated floor from rising, i.e., it is an anti-moisture barrier.
Floor heating should be placed on special tiles inside the floor that usually have an anti-moisture film. If they do not, a special film should be placed under the insulating sheet.
With which boilers does the underfloor heating system work?
The system works with any type of boiler, table or wall-mounted, oil or gas, electric, etc. A mixing valve located at the boiler outlet is responsible for regulating the temperature to the operating system (approx. 40 ° C) regardless the temperature coming from the boiler. Specifically, low temperature boilers and condensing boilers have high efficiency and they provide a low outlet temperature as well.
What is the difference in water temperature between supply and return to the underfloor heating circuits?
The difference is between 5 and 10 .C.
How many circuits can a floor heating collector have at most?
The maximum number of circuits is 12 per collector. In order for this number to be exceeded, a technical study is requiered.
How long does it take for the system to reach the desired room temperature?
When the system is activated for the first time, the entire floor surface must firstly be heated; therefore it takes 2 to 5 hours for the space to be heated, depending on various factors, such as the type of insulation of the house, the type of final floor, the exterior temperature etc. That is why, underfloor heating achieves great energy saving, when it works steadily, without interruptions.
Why is the extra added to the mortar?
To prevent the formation of bubbles inside the mortar when it binds. Air bubbles exert an insulating effect that is counterproductive to the proper functioning of the system.
What is a pressure test?
The current regulations require heating installations to be controlled at pressures 1.5 times higher than the operating pressure, with a minimum of 6 bars.
Can a thermostat control many electrothermal heads?
Yes, different heads can be connected to each thermostat.
Where are the thermostats placed?
In an inner wall, 1.5 to 1.8m from the ground, away from any source of moisture, any source of heat (TV, electronic equipment, ...), direct sunlight, and possible water splashing.
What height is necessary for the installation of the floor heating?
The thickness of the thermal concrete, depending on the insulation panel and the diameter of the pipe chosen, varies between 7.5 and 9.5 cm plus the height of the final floor to be installed.
Is the BETAPEX pipe suitable for floor heating?
STH recommends for the underfloor heating installation the BETAPEX EVOH pipe with oxygen barrier. The oxygen barrier prevents oxygen from penetrating through the pipe wall, which can cause oxidation of the metal parts of the installation.
What is the purpose of the oxygen barrier?
It is an outer coating applied to the pipe to prevent air from penetrating the wall of the pipe, which causes the continuous oxygenation of the water, which in turn causes oxidation of the metal parts of the installation and consequently reduces its service life.
What is the use of perimeter insulation?
It absorbs the expansions created by the increase of the floor temperature and reduces the lateral heat losses. It is necessary to install it correctly in order to avoid damage to the final floor.
I have a thermostat that controls the temperature of several rooms. Can I put a thermostat in every room?
Yes, you can put a thermostat to independently control each of the circuits.
How many extras are added to the thermal concrete?
Add 0.3 liters to the mixing water for every 50 kg of cement, 220 kg of sand and 25 liters of water. Another method of calculation is 1 liter for every 10 m2 with a mortar thickness of 5 cm.
Do I have to intervene in the flowmeters?
At the beginning of the installation, the flow meters of each circuit are adjusted and so, you do not need to intervene afterward. Only if a room heats up too slowly compared to the others, we can intervene by opening the flow meter a little more (usually 25% is enough). If this flowmeter is fully open we can close the other circuits by 25%. These features require the advice of your installer.
Can I manage the operation of the installation so that it does not work permanently?
Yes. A timer can be added to the control unit, which allows the operating hours to be set.
I have been told that the installation should run continuously without having to shut down the system. Doesn't energy expenditure increase significantly in that way?
The system is based on temperature accumulation and thermal inertia of the floor, which is one of the reasons why it achieves great energy savings. For this reason, the heat source (boiler or heat pump) should operate continuously, unlike other heating systems. The Control Unit adjusts the amount of energy in the installation and regulates the operation of the source without the need for user intervention.
Can you install floor heating on a wood floor? Is the wood deformed?
Yes, it can be installed. Floor heating does not damage the wood in any way. Wood can only be deformed if its relative humidity is above the range specified by the corresponding UNE standard, i.e., between 8% and 12%.
At what water temperature does floor heating work?
The average supply water temperature for heating is about 40ºC, depending on the type of flooring installed and the adjustment system used.
It is a system formed by circuits of pipes that are integrated in the house's floor, and thus do not take up space into the house. This system, through water, transmits the required heat by radiation. The temperature it provides is homogeneous as these piping circuits are evenly distributed throughout the house.

What do we call hard water?
Hard water refers to water that contains more minerals than normal water, especially calcium and magnesium. The higher the hardness, the more calcium and magnesium ions are in the water.
What is water softening?
Softening is the technique used to remove ions that make water hard. In most cases, they are calcium and magnesium ions. For the calcium and magnesium ions to be removed, an electronic descaling inhibitor or softener can be used.
Why install a softener?
When the water is hard, it can clog the pipes and make it difficult for the soap to be dissolved. Hard water builds up deposits that clog pipes and can even damage boilers and water heaters. They are also harmful to home appliances since they alter their surface.
What is an electronic inhibitor?
It is an electronic device that generates electromagnetic waves with frequencies similar to those of calcium ions. The pulses generated accelerate the crystallization of calcium, creating calcium carbonate (CaCO3) which, being electrically neutral, does not settle on the surfaces.
What is the advantage of the electronic inhibitor over the softener?
It is a natural procedure, without the addition of chemicals. The water, as it has not been softened, does not undergo any chemical treatment and retains its original mineral content. Water remains drinkable and rich in calcium carbonate and minerals, necessary and beneficial to health.
What is the function of UVc sterilizers?
UVc sterilizers are water processing devices that act against microorganisms that are accidentally contained in drinking water such as bacteria, viruses, fungi, mold, etc.
What are the advantages of UVc sterilizers?
Disinfection of liquids with ultraviolet radiation has many advantages, as it leaves no residue and does not change its composition or properties as other chemical procedures do.
