(oust-25c I e v e l applied on the wall and covered with the secondv My invention relates to room-heating systems of the kind -in which the heating elements are concealed within the walls, the floor or the ceiling.

The invention has for its object the provision of room-heating elements which may be installed in such a small outside layer of the walls ceilings' and floors as normally is formed for instance by; the plaster work. The heater according to the invention has therefore the double advantage of a -]0 minor loss of heat due to the thin concealing layer and of a cheaper installation, the provision of grooves in the wall-structure hitherto usual, being avoided. 1

According to the invention the heatinglpipes' used are of a small diameter, for instance of about 10-20 inm. for vertical installation in walls and of about-25 mm. for horizontal installa- To these pipelines metal radiating strips are applied tangentially to the pipes and in a plane which is" parallel 'to the-heat transmitting surface of the'wall, fioortion in floors and ceilings.

or ceiling. The radiating strips whichmay',' for instance, be of aluminium or another high conductive material are distinguished according to the invention by the circumstance of 'having a zone near'the pipe covered with a heat-insulating materialand a distant zone which is directly radiating. Thus a greater uniformity of heat transmission is attained. -The metal radiating strips may be arranged atvarious distancesfrom each other according to the amount of heat which it is desired to transmit. Preferably the pipes are placed betweenpieces ofan insulating material,

as for instance Celotex adapted simultaneously to' form a backing for the'metal strips.

In the case of floor heating these few members placed directly beneath the parquet floor or beneath an earthenware or cement tile pavement may be 'sumcient to form a good room heating 40 system, but for concealing them in the plaster of a wall or of a ceiling special provisions are neoes sary to avoid the destruction of-this easily crum-'- bling material-as a consequence of the thermalexpansion of the metal parts. According to the invention the concealing of heating elements, al-'- waysmoving under the effects of the changes of temperature, beneath'a thin coat of wall or ceiling plaster is provided for by means of a thin layer of metal wool, metal wadding and like materials of high heat conductivity and elasticity which is located between the elements and the plaster. This layer of metal wool may be fixed'in its position by suitable means, preferably by wire netting. This latter material may also beused to hold together complete heating aggregates'in the form of a board comprising an insulating base, a metal pipe, metal heat-transmitting strips and a layer of metal wool, these aggregates which do not exceed the thickness of the first plaster cost of a wall being mounted at the workshop,

coat of plaster.

'Ihe invention will be more clearly understood by a consideration of the following detailed de-'- scription taken in connection with the-accomv panying drawing forming part of thisv speclilca-Jv tion, with the understanding however. that the invention'is not confined to any strict conformity with the showing in the-drawing, 'butmay be changed and modified as long as such changes and modifications mark no'material departure from Fig. 2-is a front view of a pipe line with its metal I 4 Fig.5 is a plan viewof a floor heating element.

they may have any other suitable section. On.

the pipes are applied by soldering or only by their:-

springiness metal strips 2,- makingat one of their ends 'an extensive contact with. the pipe so as to ensure a good transmission'ofheat. As shown in Figuresl and 2, themetalstrips 2; have a small step 2 dividing. the inner zone, which has to be coveredby an; insulating-material 3, having they thickness of the step from the directly radiating 'outer zone. In Figs. 3j and 4 there: is shown a layer of metal wool 4 covering both .the inner and the outer zones of the strips. extending alternatively on the two sides of the pipe: -.-TIhe"metal-woo1- layer being protected adjacent theipipe against, the heat of the pipe by theinsulatin'g materialv 3,1

the second coat of plaster, which penetrates more:

orle's's' in the metal wool layer, absorbsthis heat forretransmitting it to the room. Fig. 3 shows on a wan l0, pieces-f asuitable material, for ex@: ampleboards of Celotex so applied as to leave between the said boards 'ajgroove forrthe pipe?! and also forming-a base :for'the heat transmitting metal strips. Itisunderstood that instead of strips2 extending only on onesidegof the-pipe. shownin Fig.4, strips'may be used extending on both sides, as shown in Fig. 2, andv instead of:

using separate strips in closeadiacencavuse-maybe made of a single continuous sheet 22 (Fig. 4) which may be welded to the pipe I. In order-.120 reduce the effect of expansion; the metal sheet 22 may preferably be notched like acomb.

The layer of metal wool 4' is fixed in contact with the radiating strips 2 and the insulating material by wire netting 5 nailed upon the pieces 8 and upon the wall 10. Instead of assembling I 5 the said parts of the heating system into the building only, they may also form a complete aggregate to be applied for example as a whole on the ceiling by means of screws I I as shown in Fig. 4. The wire netting forms an excellent base j 10 for the plaster, which penetrates through it into the metal wool, absorbing the heat without reaching the metal strips. As the thermal expansionv of the said strips is always small, a layer. of 2.0r

slabs l2 directly cover the'metal strips 2 and the insulating material 3, but :in laying the slabs provision is to be made to allow for a little movemerit of the metal strips 2. The construction. according to the invention is very simple and therefore economical. As the heating elements are incorporated in the'coat ofthe walls of the rooms and insulated towards the walls, all of the radiated heat is utilized in the rooms. 1 I
