The present invention relates to a radiant
heating panel for u.se particularly as a floor or a Eloor
panel.
It is considered advantageous to arrange
heating coils in floors. For this purpose metallic
pipes, running back and forth, have up to now most often
been laid in concrete floors, which have been poured
around the metallic pipes functioning as heating coils.
The above stated technique is marred by several
disadvantages. First of all, one is in prac-tice bound
to concrete floors and in this connection is forced to
pour the 100r around the coils. If leakage or other
defects arise, the floor must completely or partially be
broken up, which involves high costs and great problems.
Moreover such coils are forced to heat up the entire
floor, i.e. a very large mass, whose raising or lowering
of temperature requires long periods of time. Advanta
geous regulation of temperature during short periods of
time is in this connection completely out of the
question.
The object of the present invention is
principally to eliminate the above stated disadvantages
and create a new heating panel, particularly as floor
or floor panel, which easily, quickly, simply, and in
an economical way can be applied on arbitrary
foundations, and in which connection such a heating
panel without difficulty can even be produced by laymen.
The above object is achieved, according to the
present invention as herein broadly claimed, by the
provision of a radiant heating panel comprising a base
plate having grooves in one face, said panel having one
side confronting the space to be heated, and separate
heating conduit means for a heating medium in said
grooves, and means transferring heat between said heating
medium in said conduit means and the space-to be heated,

characterized essentially in that the walls of said
grooves diverge from said one face toward the bottom of
the grooves, forming a throat at said face, at least one
of the conduit means and the base plate being
elastically deformable, the heating conduit means having
a width somewhat larger than the width of the throat r SO
that the heating conduit means can be snapped into and is
retained in the grooves by said throat.
The invention is li~ewise broadly claimed
herein as a method oX producing a radiant heating panel
from a base plate having grooves in one face, heating
pipes for a heating medium to be mounted in said grooves,
and a heat-conductive means d:irected toward the room -to
be heated to radiate heat from said pipes to said room,
characterized essentially by the steps of: providing
walls in said grooves which diverge from said face
toward the bottom of the grooves to produce at said face
a throat of a given width somewhat less than the width
of said heating pipes, and inserting said pipes into said
grooves by temporarily deforming at least one of said
throat and said pipes, so that said throat retains each
pipe in its groove.
Following is a description of an embodiment of
the invention having reference to the appended drawings
wherein:

In the drawing figures a base plate is
designated with 1, which preferably consists of ex-truded
plastic, which can be produced in desired standard
widths. This base plate is equipped with mutual prefera
bly parallel grooves 2, whose depth 15 can amount to
e.g. approx. 2/3 of the thickness of the plate. The
profile of the grooves is preferably suchl that the walls
of the grooves 3 at least in connection to the side of
entry of the grooves diverges toward the bottom of the
grooves 4. In the illustrated embodiment the grooves have
a trapezoidal or salmon's tail-shaped profile, at which
the walls of the grooves 3 at the open side of the groove
and at the bottom 4 are softly rounded or bevelled, so
that an approximate Z- or S- shaped construction is
obtained.
In the grooves 2 heating pipes 6 of an
intrlnsically known type are placed

in an in-trinsically known ~!ay, i.e. it can be a r~UeStiOn of ~lastic or
me-tallic pipest eventually pla;tic sheathed me-tallic pipes, Nhereby the
~lastic c~m be Ijolyethelene HD wi-th an outer diameter oI 3 r~n and an in-
ner dia;leter oi ~ lm, and in which connection the coils run ei-thex back
and forth throu;h a heating panel or a cornplete floor, or in which case
intrinsically knov~n distributors are arranged a-t desired locations, so
that the heating lne(lillJn in adjacent pipes can flow in the same direction
causing rninor loses of pressure and a quicker and rllore even heating resp.
reduction oi temADerature, if so is desired. rhe hea-ting pipes can have
arbit-raly profile, but only circle round profile will certainly be con-
sidered, ~lhose diarmeter in accordance with a preferred embodiment is
somev/hat lar~er than the width 16 of the throat of the groove causing a
certain snapping-in effect, in which connection the hea-ting pipes and/or
the base pla-te are deformed somewhat during insertion of -the pipes~ in
which connec-tion a minor expansion occurs in the wider interior of the
croove, ~o that the pipes are retained in the grooves without special
means of assis-tance.
As revealed by ~-ic~lre 2, -the inser-ted pipes extend somewhat outward over
the upper side of the plate 1, ~hich is forrned by the ridges 5 be-tween-
-the ~;rooves 2~ which result in, that an installed cover pla-te 7 princip-
ally will rest on the pipes 6, which accoun-t for a dis-tance 12 between
the underside of the cover plate and the upper side of the base plate.
The cover plate or plates are designed to admit anchoring studs 8 and/or
anchoring screws 9, which are designed to be inserted into stud holes 13
resp. screw holes 14 in the base plate 1, in trhich connection such a bond
lS desigrled to be ti~htened dowrl;1ard and reduce or pre~eraDly oblitera-te
the distance 12 accordincP~ to figure ~. If studs are used~ these are pre-
f`erably rirMly ~nited with the cover plate 7 and on -their shaft section
have annular rings or other intrinsically known snapping-in construction~
which correspond to walls of holes provided with annular depressions, so
tha-t applied pre3sure on the cover plate within -the area for the studs
causes these s-tuds to autbmftically penetra-te and bite into -the intended
holes and retain the cover plate in the dov~nward pressed position.
In accordance wi-tn a preferred embodimen-t the heating pipes o and/or the
Dase pla-l;e 1 are constrllctfad ol material which can i)e ;leforrned, so tha-t
e.g. in unburdened condition, l~ipes which have a cLrcle round profile are
déformed l;o be clarflped to form in -the -trapezoidal grooves, ls is revealed
by figure ~. In this connection the pipes consequen-tly fill out the grooves
,

and achieve in addition, insteat1 of' line contact ~/ith -the cover plate, a
considerable suri'ace contact and in this .~ay excellent and considerable
transf'er of hea-t ~e-tween the pipes and the cover plate.
~he s-ta-ted trans~er of hea-t and/or the retention of'-the pipes in the groovescan be increased by rneans of that a gap filling compound 10 is introduced
in the grooves9 which is fluid or half' fluid, cventua~ly first stiff or firrn
and then iluid or hal:f fluid af-ter having been hea-ted, so that in the in-
-termediate s-tage according to figure 2 a forcing aside to the sides,of the
stated gap filling compound is obtained, which in f'inal stage is pressed
all the way up to f'ill out eventual remaining cavities directly under the
cover plate 7. The gap filling compourid 10 can be a glu8 and/or other com-
pound ,;ith advan-tageous heat conduction ~prbperties. Of course it is also
possible after assernbly of the pipes to introduce such gap filling com-
pound in the fold between the pipes and the throat of the grooves. If the
compound is a ~lue, this can eventually guarantee -the creation 'of a durable
bond between the cover plate and the pipes and/or the base plate.
Deformation of the pipes and/or the base plate and stated effect of the gap
filling connpound can eventu~ally be favoured in that in the interrnediate
stage according to figure 2 warm or greatly heated water is allowed to pass
through the pipes, so that the pipe rnaterial and/or the material of the
base plate so~'tens, by what means in a short time and in a simple Manner a
simple clamping to forrn according -to figure 3 is obtained. If greatly
heated water is conveyed through the pipes, a cover plate ma-terial, especi-
ally with laminated cover plates, can eventually be considered, which sof-
tens and-then absorbs a portion of the heating pipes, which in such a man-
ner become erilbedded in -the cover plate.
'~he entire upper side-of' the base plate 1 including the walls of and the
bottoms of'-the grooves and/or the under side of the base plate can eventu-
ally be provided with a heat reflecting layer~ e.g. by means of anodizing.
~oreover the gal) filling compound can be~applied over -the entire surface
of the base plate i'or the filling 01lt of eventual additional irregJularities
and/or functioning flS glue for~the entire under side of the cover plate.
As s-tated~ the cover plate c~an consist of laminate, where at least an up-
per la-yer has f'orrn stability for the purpose of ob-taining~a level floor.
~'he cover plate can consist of rnetal and/or plastic and/or other material
and i-t and/or -the base plate will have a stiffening function~ so that a

heatirl& parlel accordin~ to the invention c~n be arJplied on an arbitrary
~'ourl(lation. Under the brlse l,late an e.~i;. insula-tion shcet 11 of intrin-
~ically l~nown cons-truction is pre~'eraoly arranged to be glued onto it.
The hea-tin~ pipes can as already stated, be installed as an endless pipe
or in the ca~e of a rnodular system suitable couplings can be arrrmged be-
tween the udjacerlt panels, In addition it is possible to deliver entirely
or partially cornplete heating panels~ in the latter case e.g. hea-ting plpes
inserted in the grooves 2, which can alterna-tlvely be delivered attached
on the underside of' the cover plate.
In all cases one obtains small heated masses which result in that consider-
able raising resp. lowering of temperature can occur in the shortest con-
ceivable period of' time. The ~oundation can be arbitrary and a concrete
~loor can be poured quic~ly and easily and without consideration for la-
borious manual laying of' heatlng pipes according tolanltogether individual
pattern in each separate case. l~'urtherrnore the overall heigh-t can be'kep-t
very :Low and such heating panels can advantageously be arranged even in ol-
der houses on existlng f'loors. Of course the heating panels according to
the invention are sult~ble even f'or installation on walls and ceillngs.
Owing to~the small heated masses and the~,rea-t area of contact the temper-
ature o~ the transport rnedium in the heating pipes~can re held at the low-
est conceivable level in order to yet achieve qulck, high and dependable
heating, 'Thls rrla~res the heating panels accordlng -to the lnventlon very
suitable for e,g. heat purnp s,ysterns~and the like.
1~ relatively heavy cover plates are used~ speclal anchori~ means such as
screws~ studs and eventually even gluing can eventually be eliminated. '~he
previously stated deforrnatlon of the heatlng plpes and/or the base plate
exists~prs~erably~beslde a c~ertaln permanent elastlcity and/or medium
pressure f'rom the heating~rnedlum in the heating pipes~ so tha-t these~ are
; always pressed I`or good contact against the Imder side of the cover plate,
whlch ~llarantees perm~nent good tIians~er o~ heat.
The forms of the embodiment descrlbed'above and illustratèd in the accom-
pany~lng drawlngs are only -to be consldered as non-limltlng examples~ which
can be modlI'led ~md supplemented at will within the scope of the inventive
idea, Consequently instsad of screws resp. stllds, anchorlng fasteners~
such as pop rivits and the llke runnlng through both the~cover plate and
-the base plate can be consl~dered.
