Low-temperature floor heating system with short reaction time, for dry construction

Invention, development and production Hans Loss, A 6900 Bregenz, www.lithotherm-loss.at

Before laying the LITHOTHERM moulded boards, complete the following work:Attach commercially available edging strips and use dry levelling fill (e.g. CEMWOOD) to ensure a level surface... Fit the insulation boards,pay attention to the level and height (minimum required pressure resistance of the insulation boards 600 kg/m2, if necessary fit a load distribution panel on the insulation board). When using insulating levelling fill, also lay 2 x, 1 cm thick overlapping soft fibre boards. On wooden beam ceilings with a flat underlying surface, lay a soft fibre board with a thickness of 1 to 2 cm as footfall insulation. (If necessary also lay a vapour barrier, ask your architect.)The underlying surface must be even and firm.

VERSION 1 for the following floor coverings: Floating parquet, tiles, stone flags, glued parquet.

Laying the LITHOTHERM moulded boardsStart laying the LITHOTHERM moulded boards in a corner. Slide the first board up to the edgingstrip and ensure a distance of 8 cm between the end of the board and the wall. Engage the secondboard with a distance of 11 cm from the wall. Lay the remaining rows with an alternating distancefrom the wall. Continuing in a triangular form, carry on laying the boards, working out from the corner. The distance of the boards at the front serves to accommodate the pipe turns and the col-lector pipes to the manifold. Furthermore a gap of approx. 3 - 4 cm can be left along the groovesbetween the boards and the wall.

The LITHOTHERM aluminium composite piping is then installed. Depending on the heating requirements, the pipe distance should be 9 cm / 13.5 cm and extended in each case by 4.5 cm. Fill any recesses on the edges and doors with a fast-drying screed or bonded dry levelling fill.

Floor covering: Floating parquet Roll out non-woven material or cork mats, then lay the parquet (laminate) floor according to the manufacturer's instructions.

Floor covering: Tiles, stone flags, glued parquetLay the fibreglass net with a mesh width of 1-2 mm onto the LITHOTHERM moulded boards and apply a flexible adhesive using a trowel with-out exerting any pressure and distribute smoothly and evenly. When the surface has dried slightly, lay the floor covering in the conventionalmanner. Provide expansion joints in the floor coverings at right angles to the heating pipes. Tiles or stone flags of any size can be installedon the LITHOTHERM system.

Floor covering: For industrial floorings refer to the separate documentation.

VERSION 2 for the following floor coverings: Floorboards, ship plank, strip wood, nailed parquet, carpet,cork, plastic and sports floors on fixed profile strips.

Laying the LITHOTHERM moulded boardsStart laying the LITHOTHERM moulded boards in a corner. Place the profile strip close to the edging strip and firmly press the first board onto the profile strip with a distance of approx. 10 cmat the front. Lay approx. 5-6 boards in the first row and firmly fit the second profile strip. Fit the subsequent board rows, all with a distance of approx. 10 cm between the front of the boards andthe wall. Continue laying the boards in a triangular pattern until the room is fully covered. The dis-tance of the boards at the front serves to accommodate the pipe turns and the collector pipes tothe manifold. Furthermore a gap of approx. 3-4 cm can be left along the grooves between theboards and the wall. If it is not possible to firmly clamp the profile strip between the boards and

the wall, it must be cemented with construction adhesive. As soon as the LITHOTHERM floor has been fitted, the LITHOTHERM aluminium composite piping is laid. Depending on the heating requirements, the pipe distance should be 9 cm / 13.5 cm and extended in each case by 4.5 cm. Fill any recesses on the edges and doors witha firm dry levelling fill.

Floor covering: Floorboards, ship plank, strip wood and nailed parquet Lay the LITHOTHERM moulded boards with LITHOTHERM profile strips as described above (also refer to the drawing). The wooden floorscan then be nailed or screwed to the fixed LITHOTHERM profile strips.

Floor covering: Carpet, cork, plastic and sports floorsLay the LITHOTHERM moulded boards with LITHOTHERM profile strips as described above (also refer to the drawing). Finally screw an OSBboard with tongue and groove, thickness of 12 mm, onto the LITHOTHERM profile strips. Lay the floor coverings, either floating or with adhesive. Fill any recess on the edges and doors with a firm dry levelling fill. (Take the expansion of the wooden parts into account.)On sports floors lay an oscillating foam layer below the LITHOTHERM moulded boards. (Made by Getzner)

Floor covering: For industrial floorings refer to the separate documentation.

CAUTION!Only persons responsible for subsequent processing of the floor are permitted towalk on the unprotected LITHOTHERM floor. Passages must be covered with firmboards during the construction phase. The LITHOTHERM moulded boards must be checked to ensure that they are dry before laying the floor coverings. The material moisture, based on the dry mass (specific weight of the LITHOTHERM boards 1.3) should not exceed 10-12% whenlaying wooden floors. Measuring method, electronic. Before laying wooden floors,leave the material for some time in the room to acclimatise. Always comply fullywith the installation instructions. System insurance is in place in addition to the statutory warranty. Warranty claims and insurance protection claims will only be accepted if the installation instructions have been strictly adhered to. (Always useoriginal LITHOTHERM accessories!)

LITHOTHERM characteristics

The heating pipes installed directly un-derneath the floor covering guaranteedirect emission of the radiated heatinto the room. The grooves of theLITHOTHERM moulded boards that areopen at the top increase the radiationarea below the floor covering by approx. 60%. The increased flow of heatdirected upwards results in a regularfloor temperature and keeps the tem-perature of the underside of theLITHOTHERM moulded boards approx.30% lower. With the LITHOTHERM system first the room is heated, thenafter a longer heating period also theaccumulator (LITHOTHERM mouldedboards).

The heart of the LITHOTHERM system is the LITHOTHERM moulded board. It is made of clay or lava and is hall-marked by constantly high quality, maximum stability and dimensional accuracy.

The slim installation thickness of 45 mm and the solid size make the boards an ideal dry screed for newbuildings and renovations. (Construction time can be shortened by approx. 6 weeks.)

The heating pipes running directly underneath the floor covering only require a very low admission tem-perature. This makes the system ideal for combining with condensing boilers, solar systems and heat pumps.(Efficient use of renewable energy systems.)

An example: In the average heating period, approx. 5 monthsper year, heating energy is required on a short-term basisfor a brief time. The LITHOTHERM floor heating providesthe full heating capacity after approx. 25 minutes and main-tains a pleasant temperature in the room for several hoursafter the heating has been switched off.

A contribution to sustainable CO reduction!2

It is a well-known fact that energy can-not be destroyed, but it can be wasted.
