Foreword: Mention of floor-heating,we mostly concern about the heating pipe or boiler equipments,brass fittings are also very important central equipment.Because of different reasons,brass fittings always ignore by people,the customers are lack of comprehension.It known that there are not so many articles which introduce specilized and systematically.Is it not important of brass fittings,or not essential,or not so many technological content,or nothing to say? From this side,it can influence the lack of brass fittings' attention and its embarrassed station.
& ;nbsp; In the South dependent heating system,it includes header source equipment--boiler,transfer equipment--pump,manifold,brass fittings, structure layer--floor pipe layer and temperature control system etc.Because of the price competition,once the customer cut the price,some sellers will through the element arrangement to decrease the quotation of whole system.Since customers usually pay more attention to the boiler and heating pipe,lack of understanding about other system equipment.The floor-heating sellers always choose to decrease the level of brass fittings.Thus,high grade brass fittings become the victim.This is the puzzled problem which the high grade brass fittings manufacture communicated with me.Otherwise,brass fittings manufacture usually promotion products to the middleman.They are hard to find the ending customers to introduce and recommend,once the middleman regard the price is too expensive and don't want to promotion,they will feel puzzled,lossing... So, these manufactures usually complain the unspeciality of middleman.
& ;nbsp; Is it important of brass fittings? We think it is very significant,it play an essential effect in the dependent heating system.If we assimilate the boiler as the driver of car,thus,the brass fittings are the gear-box of car.If we assimilate the heating pipe as our blood net,thus,brass fittings are the central vervous control system.Customers always concern about the good boiler and pipe,then ignore the brass fittings.They think use the good boiler is enough for the floor-heating system.This point is wrong.We can see that we often choose the world brand boiler to customers,but use the easy and worse brass fittings,the control system is also simplified,try to think,is it the top grade floor-heating? Absolutely not!

&a mp;nbsp; The history of floor heating:Floor radiate heating is an old and new technology.The floor heating can track back to Ming Dynasty in our country,it only used by royal family,such as the Imeperial Palace,it build flue under the black brick.In winter,it transfer the smoke through the flue,and reasonably dispose the windows to get the header into the indoor,make the room warm. After then,in the north of our country,people apply the heated brick bed to get warm,so as the Korea and Japan.Throughout the history,human constant to come down the civilization,creating,development and improve.Now,with the coming of mordern technology,the floor heating developed from the original flue header to brass valve radiate header.This technology apply in developed countries since 1930'. It was applied in Great Hall of the People since 1950' in China.
& ;nbsp; & nbsp;The theory of Floor heating: floor radiate heating make the whole floor as the header,through the medium to heat the floor.It passed up and down to utilize the header storage.Because it can come the different step temperature,then make people comfortable.Floor heating is the most comfortable heating method at the moment,it is the symbol of mordern life quality.
& ;nbsp; The assort of floor heating:according the different heating method,radiat floor heating can devide to low temperature hot water floor heating and header wire radiat heating.Low temperature hot water floor heating make the hot water below 60 degree as the medium,cycle between brass valve and header pipe,through the header thansfer method to supply in room.
& ;nbsp; Header wire radiat heating is make the low temperature header wire as the souce,heat the floor,through the radiat to supply header.
& ;nbsp; The advantages of floor heating:
a.Comfort,health and tidy:Floor heating is the most comfortable heating method,the temperature indoor is average;hard to cause pollution,the air is fresh;provide the blood cycle,improve the process of metabolism.
b.Save the space,beautify the room:It won't use the pipe,so it will enlarge the use area,easy for decoration.
c.High efficient:It has high efficient and low header damage during the transfer;radiat floor heating can use control departly,users can manager according the situation,actively save the energy.
d.Good header stability:It has large header storage and good stability during the heating.The temperature changed slowly when it stopped.
e.The low cost:Compared with other heating equipment,it save 20%,can fully use low temperature hot water souce,decrease the cycle cost.
f.Long use period:During the low temperature floor heating,the plastic pipe and header wire are laid underfloor,it won't corrosion and dirty,also won't distroy by people.The use period is same with the building.
