"I will have a warm floor everywhere !!! I will not have heating radiators !!! Warm floor is an economical heating system !!! I will not pay little for gas !!! "......... These are the pink dreamers of the amateur - the developer when they wrapped around to build their home. They are excusable - amateur!
"We made a heating system from warm floors and everything works fine !!! Condensation gas boilers operate in low-temperature modes, and this is very good for warm floors !!! You will save gas !!! Look at how beautiful we wake up the branches of warm floors !!! So do in all of Europe !!! "... .. Sing them installers of heating systems. "Any whim for your money !!!" ... they purre themselves under the nose. They are not fortunate - pseudoproproproprofisanals! Shoot!
One wanted (because it does not know how it ends). The second did (because so wanted the first, and the second does not want to bother with other people's problems) .... Idylli in general ....
So! I spawned bile, now I will imagine the arguments. There will be two sections: theoretical and practical.
Let's start with practice.
We will not walk far - central Finland. More precisely, the city of Jyväskyulya, the central part, the high-rise building, applying for elite. My brother, working there by a doctor and saving on everything that you can, bought an apartment here. Dust-native with a personal sauna and a tiny gym. There are no windows with windowsill in the usual understanding. There are window blocks from floor to ceiling. There are no complaints to the windows at all. Finns are able to do the windows. From heating only warm floors.
When he bought an apartment, I expressed doubt that it would adequately work and surprise that Finns were so built. Well, built and built! We will see!
At first, everything was hurt! But by the third or fourth year of operation, it became obvious that during frosts below -10, it becomes no longer just cool in the apartment, but very much Ice! Get warm things, slippers. And in severe frosts, fluffy uggs. Cold air slipping from the triple glass was stupid dubbing on my feet. Increasing the temperature of the warm floor leads to a fun effect. Warm things are cleaned, the TC becomes warm, but slippers with uggs remain, TC walk on the hot floor is not ice! Moreover, the high contrast of the temperature between hot floors and cold windows creates more intensive circulation of cold air on the floor side of the windows. If we consider that the air temperature on the street is jumping with an amplitude of 10-15 degrees per week, depending on the direction of the wind, you have to constantly turn the regulator. At first, it was boring, and then just recharge on it. Put the average temperature, and they live.
Well, this is an urban building. Consider individual developers.
House in two floors. From central communications only electricity. The main energy installation is a fireplace. Auxiliary - thermal pump. Heating elements in the house - warm floors. Warm floors are always warm. The fireplace is worn out only at the positive temperature on the street. In the long beds (the fireplace in the center of the house) hang the electroconvetern included in the outlet. They include when the street is loaded below -15.
In general, in Finland trouble with gas. It is not. In any case, the private developer does not shine. Therefore, wood heating in the most intricate manifestations is very common. For the ordinary Finn, living in his house constantly throwing out something in the furnace - this is how the tea ceremony is for the Chinese, and for us Fridays one hundred grams. You need to know and understand it. Firework workpiece - Normal practice. Moreover, the Finns are not very whimsical to comfort in terms of temperature in residential premises. It cooled down? Think of firewood, dressed warmer! And heating only with warm floors is a consequence of economy during construction. Why do the radiators with pipelines, if in each house in the center there is a large fireplace? And it is this fireplace that will be treated all winter. And clean the glass from the soot and clean the fireplace from the ash and crumbs from the firewood sweeping from the floor will be constantly. And the warm floor (does not matter - water or electric) is so! - Improve!
Now about where heating is used exclusively with warm floors without auxiliary systems. Oddly enough, this also exists and also in Europe and works great.
These are mainly industrial and warehouse complexes. The topic is excellent - wrapped the warm floor, put the racks along the walls and no batteries with the pipes are not needed. Well, if the warm floor applied in combination with industrial heated ventilation with recuperation, it works in general well! There are actually no hard requirements for the comfort of the temperature of the warm floor. Loaders on wheels and workers in the specialobus are not fundamentally. The fact that ventilation is moderately noise - so it's work! Everything is noise here.
Let's go back to our homeland. Our compatriot, picked up the wave of warm floors "as in Europe" and not knowing about the accompanying nuances with an open element throws into the construction! In the aggregate with stupid mistakes in the strapping of the boiler in the boiler room, the picture is turned out sad. Money is not small, but everything is crooked and oblique.
And the saddest thing! When guests come to the developer, (as a rule, no less successful and respectable people) and ask "Well, and how?" No one! No one admits that he lied on all her money!
The second part is a theoretical with an example, calculation and numbers - I will set out a little later. So the post turned out to be great! Anyway, no one will read!
