Underfloor Heating Criticism and Benefits
Underfloor heating can be made of thermal insulation must be very good. The buildings of the glass surface, the amount of air coming down from the surface of the glass and the glass is cold radiation.Even more often in front of glass spaced pipe close to the glass surface in cold region, döşense effect will be felt. Comfort will deteriorate.
If heat loss in buildings that are not good is more isolated, even when all the tiles to the surface of the pipe under the floor temperature 23-24 ° c. This will break the desired comfort.
Underfloor heating after the isolation placed on concrete floors, the main substance Polypropylene (PPC), Polyethylene Covering (VPE) or Polybutylen is taken from a plastic materials (extrusion) is made by heating copper pipe or tubing. If you’re placing a leveling pipes (alum) is placed in the concrete on top, coating material. This type of heating floors can be from the wall or from the ceiling.However, the most common application of floor heating. According to the calculated heat pipes scene modulation circulates within the tiles in an appropriate format. The layout of the pipes used for custom pipe holders. Distribution all columns (~ 100 m2) and the floors are provided with the collector is placed. The following illustration is a single-storey structure of floor heating system implementation.
Under pipes, is written in the calculated thickness insulator for heat and sound insulation and a layer of screed it is obscured with the pipes. In this way the heat after the concrete floors to place 8-10 cm height.
1. Underfloor heating system has the following assumptions can be made.
a-if the room temperature at 20 ° c
Houses with floor temperature is 23-24 ° c
Indoor swimming pool (Max) 29 ° c
b-50/40 ° c water temperature one meter pipe 20 kcal/h heat like marble and ceramic tile, move was accepted at zero.
Carpeted flooring in.. 12% surcharge
Encased in wood flooring in.. 35% surcharge should be applied.
Accordingly, in the case of the marble tiles or carpeted, both depending on the material’s heat permeability coefficient under room temperature floor pass in greater resistance differences are emerging.
c-80-100 meters from the collector output plastic tube can work as a group coil.
d-should be given an inclination to Hang out of the air.
e-Pipes, hydraulic test should be applied before his burial. 1400 kPa pressure test should last 24 hours.
Underfloor Heating Critiques
a low temperature in the area in front of the glass. Glass front less often in tubes of glass at the front of the room temperature remains below the average of döşense. Some firms in Europe tile heating glass front of they recommend using of serpentine to be out in the open. Otherwise, at least in front of the cam in-room temperature, is on the edge of the wall against the maximum.
b-the building’s warm-up period. Apartment-type buildings warm up time 5-6 hours.
c-leg irons, swelling, Underfloor heating in floor building surface temperature must not exceed 23-24 ° c. Otherwise about the swell in the feet of the living.
d-Dust on the floor will dry. Dust collected in the heating can cause the movement of dust on the floor. If there is criticism against the side of the dust in the system is in the form of radiator.
e-Heated flooring to prevent the transmission of the heat as much as possible the above material (carpet) and establishes the with.
f-mount and due to manufacturing errors, or as a result of the expanded pipe friction wear of the drill needs to break the floorboards to fix the pipes. Pipe can be given 20 years to life.
Underfloor Heating Advantages
a-all in a tiling field heat Underfloor heating system and a homogeneous heat distribution in the room. In this system, is the hottest flooring that the transported air higher from the floor level will get cold and will not weaken the high volume parts of air movement.
b-in this system, there is no pipe and radiator, seen offshore. Aesthetically, it is a perfect system.
c-4-5 from the scene in the system air ° c higher temperature flooring and 1-2 ° c higher temperature because the heated scenes by walls of air relative humidity of a fall in uncomfortable. According to the environment tile in the 4-5 ° c higher temperature of 1-2 mm height consists of a dry environment.Due to this situation that prevents bacterial growth floor heating is especially recommended for hospitals and kindergartens.
d-Mahal air warms him with large surface due to the low temperature difference between air, small surface and the scene very hot heaters warm up a lot and dust as it passes through decomposition, accordingly, have been disposed of in the system problems like pollution.
as a result of the fact that with more e-Warming radiation according to other heating system 1 ~ 2 ° c, it is possible to find the same comfort at low temperatures.
f-Underfloor heating system particularly high buildings (mosques, churches, Sports Hall), making it an ideal for heating is desired. In addition, housing, schools, workplaces, such as venues for years with success. Heat is very high places the needs of flooring heating is necessary to use or not to use reinforced. Here the border 120 kcal/m2h. Floor temperature must not exceed + 29 ° c. Weekend houses and sudden temperature change desired (wedding halls, etc.) places late due to heating and cooling may not be appropriate use of late. System at low temperature (max. 60 ° c) heating water.To prevent corrosion of some boilers and boiler brands except putting the mixer valve is mandatory.
Underfloor Heating Use Locations
Underfloor heating can be used successfully in the following places:
– Indoor swimming pools, walking around the pool areas
– Hospitals, kindergartens (hygiene and the lack of an outside element because of the danger to)
– Like the mosque floor height where more appropriate due to the vertical temperature distribution (also known as convective heating systems, hot air is collected above)
In contact with soil in the heated scenes, for example – the basement floor or non-villa experienced can be used in places such as basements. Floor heating, radiator heating can also be used in conjunction with. For example, luxury villas and apartments have a stone, ceramic, marble-covered volumes (hallways, bathrooms, kitchen) floor heating, radiator heating can be applied in other rooms.
