Underﬂoor heating with heated screed as liquid or cement screed

Basic heating systems

Advantages

Underﬂoor heating, with its low supply temperature, has many advantages. It runs maintenancefree, is energy saving and ensures comfortable room temperatures. Rooms with underﬂoor heating allow greater freedom for interior design. The Danfoss FH pipes enclosed in cement or liquid screed give oﬀ

The Danfoss underﬂoor heating systems with heated screed - Basic heating systems - are low temperature underﬂoor heating systems suitable for all new buildings. They can be installed in all rooms and ﬂoors of blocks of ﬂats or in business premises. The grey Danfoss composite pipes are installed, according to worked out distances, using BasicClip, BasicGrip or BasicRail on insulation panels giving the pipe lay-out. The water ﬂowing though the composite or PE-RT pipes gently warms the screed which works as heating element. It is possible to lay all common ﬂoor

• Low energy saving temperature

• Cost eective, no additional costs

• 100% impervious to air, no heat exchanger

necessary

• Comfortable, clean and healthy air

• Greater freedom of interior design, more living

space for whole family

• Maintenance-free

comfortable warmth without any drafts, - creating a dustfree, hygenic environment.

coverings on top of Danfoss underﬂoor heating, except perhaps heavy exotic carpets or special engineered wood ﬂooring which would need extra calculations when planning the system. Since low water temperatures are required to achieve the required room temperatures, Danfoss underﬂoor heating systems are ideal for use with boilers, solar energy and heat pumps. This means that producers of energy saving heat will ﬁnd an ideal partner in underﬂoor heating.

Relevant standards for underﬂoor heating

The following regulations and EN Standards should be observed when planning and installing ﬂoor heating:

EN 1991 Action on structures

EN 1264 Underﬂoor Heating, Systems and

Components

DIN 4109 Sound Insulation in the Building Industry

ISO EN 140-8 Measurement of sound insulation in buildings and building elements

EN 13813 Screed Material and Floor Screeds

Local building regulations.

Professional information on interface co-ordination when planning heated underﬂoor construction (ref: BVF).

For underﬂoor heating the EN 1264, part 4 standards are applicable. Three Danfoss basic constructions are possible: A, B and C. They meet the minimum insulation requirements in relation to use and position in the house.

The composite pipes are clipped onto the BasicRail self-adhesive clip rails at regular distances.

The maximum of 2 m between the clip rails should only be applied when using cement screed. When using liquid screed a maximum distance of 1m should be observed. Because of the ﬂuid consistency of liquid screed it could run under the pipes and can push them upwards.

BasicClip

BasicGrip

The BasicClip System is a tacker system where the pipes are tacked onto the insulation with u-shaped tacker pins. The insulation overlap panels are supplied as 2 x 1 m pre-folded panels. The foil clad panels give a perfect grip for the barbs in the EPS and under the foil.

The grid pattern on the panel foil is 50 mm which allows the diﬀerent laying distances to be kept : 100 and 150 mm for Edge Zones, and 200, 250 and 300 mm for Comfort Zones.

Any additional insulation should be laid under the BasicClip overlap panels.

The BasicGrip panel system consists of deeply drawn foil with studs that allow perfect laying of pipes.

With their size of 1 x 1 m, the panels are easy to lay and can be installed by just one person.

The panels can be cut with the usual cutter knife. The studded panels facilitate correct pipe distances. Laying the pipes diagonally is possible without additional grips. It is safe to walk on the strong foam studded panels.

When using the BasicGrip panel without thermal insulation the deeply drawn foil is correspondingly thicker.

The laying distance is calculated in multiples of 50 mm, so that possible pipe distances in the Edge Zone are 100 and 150 mm and in the Comfort Zone 200, 250 and 300 mm are achieved.

Any additional insulation should be laid under the BasicGrip panels.

BasicClip insulation overlap panels are available in 2 variations:

• with 35 mm thermal and impact sound

insulation EPS

• with 20 mm thermal and impact sound

insulation EPS

For optimum installation of the system an expansion proﬁle is available to overcome expansion gaps and door thresholds.

The system is suitable for liquid (CAF) and cement screeds (CT).

BasicGrip panels are available in 3 variations:

• with 35 mm thermal and impact sound

insulation EPS

• with 11 mm thermal insulation EPS

• without insulation

For optimum installation of the system, the following additional products are on oﬀer:

• An expansion prole to overcome expansion

gaps and door thresholds

• Door and manifold panels with varying

insulation thickness

• PE –String to seal perimeter insulation when

using liquid screed

The system is suitable for liquid (CAF) and cement screeds (CT).

Basic insulation overlap panels

Floor constructions

The individual components of the overlap insulation panels are bonded and consist of the

Continuous sound impact insulation also has to be installed.

following layers:

• Bonded multi-layer foil with 5 cm grids to

facilitate exact pipe laying

• A thermal and impact sound insulation layer

made of polystyrene

What type of insulation is used, depends on the type of ﬂoor and the building. If the concrete is even and free of other installations, a single layer

of insulation is sucient. In 90% of all new

buildings heating, sanitation and electrical services are installed which require double layer insulation.

For height adjustment, thermal insulation, e.g. EPS 035 DEO 20 mm is laid between the pipe channels and gaps around the pipes are ﬁlled with Danfoss Dry Levelling Compound.

Finally, the Basic insulation overlap panels are installed. The surface of these 2 m2 (1 + 1 m2 foldable) insulation panels are very strong, safe to walk on, and form a very good surface for BasicClip and BasicRail heating systems. The strong foil is a technically perfect base for cement and liquid screeds.

Basic perimeter insulation

Tanking for liquid screed

BasicRail

- types of installation

The Basic Perimeter insulation 150 mm consists of 8 mm PE-Foam. The double-sided adhesive tape on the back allows it to be easily attached to the wall. The adhesive tape on the room side of the foil attaches the perimeter insulation to the insulation panels. In accordance with EN 1264 the perimeter insulation can be compressed by 5 mm and thus,

When using liquid screed the insulation joints should be taped over to accept screed with a very thin consistency.

The heating circuits are laid in meander form, which is an advantage when ﬁrst installing the pipes in the edge zones of the room (Edge Zone) and then taking them to the centre of the room (Comfort Zone): the warmer temperatures of the heating circuit arrive at the outer zones (higher ﬂoor temperature), and the cooled down water heats the central zone (lower ﬂoor temperature).

together with the insulation panels, forms the required tank for the screed as well as thermal and sound bridges. When using a double layer of insulation, the additional insulation should be laid ﬁrst. Should their thickness exceed 5 cm, the perimeter insulation is installed on top of the additional insulation.

To achieve higher output around the edges or in front of windows, you can lay the pipes in double pattern. Please see recommended layout patterns in Danfoss application sheets.

BasicClip and BasicGrip

- types of installation

The Danfoss wet systems BasicGrip and BasicClip are laid in spiral form. The Danfoss composite pipe is laid in spiral form starting from the edge, leading to the centre of the room. The pipe distance is twice that of the calculated pipe spacing. The pipe is then led out of the centre between the installed pipes. The advantage is that pipes of higher temperature are next to those of lower temperature, thus

producing an even surface temperature (higher output).

Edge Zone: if a higher heat output is required, the pipes in the Edge Zone (up to 1 m from wall) can be laid closer, thus producing a higher surface temperature.

Only heated screed should be used. The Danfoss screed additive should be used when installing cement screed. The screed additive Normal CT F4 has the eﬀect of increasing thermal conductivity as well as allowing the screed to retain more heat. Both contribute to an even distribution of heat within the room and guarantee better resistance to pressure and more ﬂexibility. Liquid screed should be prepared as heated screed. To achieve a very thin cement screed, the Danfoss Screed Additive Special should be used. It achieves an even better resistance to pressure and more ﬂexibility, as well as a higher thermal conductivity.

Mastic asphalt is not suitable for Basic underﬂoor heating systems. The outer sleeve of the composite pipe is not resistant to the higher temperatures of this form of screed. The mean heating water temperature must not exceed 55˚ C when using cement and Anhydrite screeds.

Installation

Screed joints

Fresh screed mortar should be poured along the length of the composite pipes and should be well tamped. It must be protected from frost. Screed should be installed at room temperatures of above 5° C, and any draft should be avoided. Fix certain points as measuring point to ascertain residual moisture.

Floating screeds expand and contract depending on temperature, particularly heated screeds. To compensate for this, screed is divided into geometric ﬁelds. The perimeter insulation allows for some of the expansion, and movement gap strips between the ﬁelds allow for movement and avoid cracks (5 mm minimum expansion). Movement gaps have to be allowed for on room edges and between large and multi-angular areas (e.g. L- or Z-shaped). The proportion of width to length should not exceed 1:2. Joints in the building should be mirrored in the screed. The size of the areas should not exceed 40 m2 with a maximum length of 8 m. Unusual area shapes exposed to higher temperatures tend to crack easily, so careful planning of expansion joints is advisable. The type of ﬁnished ﬂoor also determines the layout of the screed areas. Screed temperature is higher when carpet is laid but with tiles the diﬀerence in temperature between upper and lower surface of the screed is signiﬁcantly higher, which means these constructions tend to crack more easily. When composite pipes cross a screed joint, the pipes should be protected with a movement gap strip against expansion and shear stress. This occurs when two adjacent screed slabs move towards each other (expansion, buckling of the embedded pipes), or move across each other (shearing), or even do both.

There should be no heating pipes within a distance of 10 cm (Ø20 cm) around that point.

The 40 cm long pipe sleeves absorb any movement of the screed and the composite pipe remains permanently protected.

Movement gap strips for BasicRail and BasicClip

Installation

Before pouring the screed, the movement gap strips are installed. The movement gap strips are ﬁrst attached to the given positions on the plan (in agreement with the screeder and ﬂoor ﬁnisher). They are attached to the insulation using the double-sided tape. Afterwards a section of perimeter insulation is inserted into the slot. Pipes going through the movement joint should be protected with an outer sleeve.

Handbook Basic™ Heating Systems

Important! Before and after installation of screed

• Heated screed is installed after pipe layout, insulations and joint gap strips are ﬁxed.

• Before the screed is installed the building/room

must be completely plastered, windows and doors must be ﬁrmly closed to avoid the screed drying too fast and thus possibly causing cracks or even other damage in the building.

• Before screeding, check again that screed areas

and heating circuits are co-ordinated and the movement gap joints are not interrupted. If the Danfoss composite pipes cross movement joints they should be protected.

• When screeding, the pipes must be under

pressure so that possible problems are noticed and can be rectiﬁed.

• Screed should be installed at temperatures

above 5° C (risk of frost).

• Should a sudden unexpected frost occur after

screeding, care must be taken not to let the temperature fall below 5° C. If it is possible to turn on the Danfoss underﬂoor heating the ﬂow temperature must not exceed 25° C.

• Heating up should follow the Danfoss heating

up protocol. It is important to check the residual moisture before laying the ﬁnished ﬂoor; this would be done by the professional laying the ﬁnished ﬂoor.

• The perimeter insulation remains in place and is

only cut to the appropriate height after the ﬂoor is ﬁnished.

The heating up of the screed should be carried out according to the Heating Up Protocol. After 7 days it is possible to walk on the cement screed, but only after 21 days should the heating up take place. For Anhydride or Calcium Sulphate based screed heating up can begin after 7 days, or according to manufacturers’ recommendation. During heating up, the automatic control should be oﬀ and the supply temperature should be adjusted manually. All joints should be checked and any solid matter should be removed from the joints. For the ﬁrst three days, the ﬂow temperature should be kept at 25° C, after that the maximum supply temperature should be run for four days, and the heating circuits should be turned oﬀ. While cooling down the heated screed should be protected from draft and rapid cooling. The

Depending on use, the ﬂoor construction will have to meet diﬀerent demands. These are deﬁned in EN 1991: Action on Structures.

ﬂoorer should now measure the residual moisture and decide whether the ﬁnal ﬂoor can be laid. It must be noted here, that during the ﬁrst year, because of residual moisture in new buildings, the heating temperature should be higher than normal. This additional moisture should dry out during the ﬁrst heating period. The heating up process does not guarantee to achieve the required moisture level of the screed. An additional heating up operation may be necessary to establish whether the ﬁnal ﬂoor can be laid. Commissioning of the underﬂoor heating after the ﬂoor has been ﬁnished should be decided by the ﬁnal ﬂooring ﬁrm.

It is important to adhere to the manufacturers' advice. The adhesives for stone tiles or ceramic ﬁnishes used in the the thinbed method must be appropriate for underﬂoor heating and for the load bearing. If the ﬂoor is laid using the thickbed method, the heating up and response times are much greater due to a higher build up. Elastic and textile ﬂoor ﬁnishes should be fully glued down. When laying textile ﬂoor ﬁnishes, it is possible to use adhesives that allow a later removal of the ﬂoor. Natural products, such as engineered timber ﬂoors or other timber products, adjust to their

environment which can cause contraction. This does not mean a faulty ﬂoor. Depending on the wood, expansion and contraction vary, but this can be minimised by keeping an even temperature. When installing engineered timber ﬂoors or laminates, the thermal resistance data should be provided as well as data for possible air gaps and additional carpets. It may be necessary to ﬁll gaps between dry ﬂoor elements before laying the ﬁnished ﬂoor.
