– Underfloor Heating

Initially underfloor heating is a new way thermansis.Sti decade 1970 the development of industry of plastic pipes and insulating materials enable the successful implementation of the system of underfloor heating, as we know it today.

It is suitable for heating because of health studies done by international health organizations have shown that the human body accepts with pleasure from floor temperature to 20 ° C and 33 ° C and annoyed when the temperature is below 17 ° C or above . In a well-configured installation of floor heating, the average water temperature in the pipes is 45 ° C , while the floor temperature ranges between 25 ° C and 28 ° C. If no one thinks that the human body temperature is 36,6 ° C, then it is unlikely to understand that burning floors. On the other hand, the advantages of underfloor in everything,regards hygiene is much: due to low temperatures of the water inlet and the air warms beyond 25 ° C, so it loses its moisture, so the atmosphere Do not stuffy. In floor heating radiant floor heat, so germs are not transferred and there are no air currents. So, is ideal for people with allergies, respiratory problems, etc..

The heating is 35% economical to operate than a conventional heating. This is explained by the fact that the temperature of the water flow in the pipes reaches 45 ° C, while heating the 80 ° C. It is known that the lower temperature of the water supply has a heating system, work more efficient boilers, heat pumps and solar collectors. If you think about that for every 1 ° C reduction in inlet temperature, We have fuel economy 3%, then perceived benefit to keep the water temperature operation as low as possible.

The system of underfloor heating is economical in operation during 30% than,what the radiator. The cost of construction is more expensive underfloor, But included in the price and insulation layer thermompeton, which omitted the cost of heating. However, this quick installation costs covered, after one saves maintenance costs caused by heating with radiators (eg. leaking pipes and radiators, body and wall painting etc.) and the costs of operation of underfloor heating, it is very low.

Underfloor heating in the floor acts as a radiator. The pipes distribute the heat where you need (rather in the basement or outside walls) and yield with minimal inertia and a lower temperature of the water flow. Moreover, due to the specific recommendation of thermompeton (that is free of air bubbles), radiate the heat throughout the interior. Even, dense laying of pipes near the outer wall intercepts the cold, while laying the lighter inside the rooms allows the transmission of lower thermal loads. Thanks to the small floor temperatures, περίπου 26 ° C – 28° C, not seen any movement of air masses with everything,What this means (suspended dust, bacteria, germs etc.).

Underfloor heating can work with the heater, after giving special attention to:

  • The two systems must be independent, they work at different temperatures. The boiler room is public.
  • In order to properly allocate the costs for oil (and if this is desired), should be multiplied by the appropriate factor in participation rates in heating costs.


Below the photo you see an intersection of underfloor heating :

The likely cause some damage is minimal, and the tubes are made of special plastic so as not to break the systodiastoles curves and not corrode or internal or external. However, in the unlikely event that a punctured tube, there is adequate equipment that allows us to detect and repair damage at the point just manifested. So, need not be dismantled over the floor, only an area of ​​less than one square meter.

Underfloor heating can be powered by any energy source, something that will prove particularly important, when the gas comes to Greece. Yet, other than oil or gas boilers, The floor can be combined with alternative heat sources, as solar energy, heat, electrical energy, proving to be a "flexible" system of heating, combined with cheaper sources of fuel.

As we demonstrated, underfloor heating is cheaper to operate than the common radiator, there are, yet, and some other elements that enhance the choice for floor, which are worth noting:

  • Saves space in the apartment.
  • Provides renovation of premises.
  • It can run on renewable energy.
  • Evenly distributes heat throughout.
  • Pleasantly warm, biologically sound manner, and warms more limbs, leaving the cooler head.
  • No odors emerge.
  • There is no injury, since no protruding radiators.
  • Provides autonomy in every room.
  • Due to the special conditions of humidity and temperature, protect furniture, antiques, musical instruments, paintings etc..
  • It is easy to configure and to operate.
  • Ichomononei floors.

Already analyzed the benefits of installing underfloor heating in our personal space, in our house. Additional, The floor can be used to heat commercial premises: Fitness, reports, stage, factories etc.. In extensive and large interior spaces of the floor it is very efficient and economical in operation, since you do not accumulate on the roof heat, but uniformly distributed in space from the bottom up. And the performance of underfloor heating is not prevented either by heavy vehicles, or on the immense storage shelves. Moreover, The stillness of the air and dust is therefore the most important advantages of underfloor installation electronics workshops, food, car showrooms etc..
Apart from the extensive and large premises, The floor can be installed even in pools inside buildings, on ramps, in greenhouses, churches, etc..

There are no restrictions in choosing the final floor. The floor can be combined with any material: tile, marble, wood (glued or nailed), plastic flooring etc.. However, must be decided in advance what the final flooring will run in any space, to adapt the study in conjunction with the thermal conductivity of each material.
The carpets reduce heat radiation of underfloor, so it is good to know what areas will get down rugs or carpets, so where the laying of pipes to be denser.

The floor compared with the heater initially slow to deliver heat directly to space, due to low inlet water temperatures. For this reason it is recommended to put the floor preparatory operation in October, ie when. observed drop in temperature.
