1.1 Collectors with ThermProtectThe Vitosol 141-FM solar pack is equipped with collectors withThermProtect switching absorber.Vitosol-FM collectors feature ThermProtect, a unique absorber coat-ing. This coating changes its optical properties subject to tempera-ture. In the standard temperature range of the solar thermal system,the collectors have the same performance values as conventionalsolar collectors. As soon as the solar cylinder has reached therequired heat-up condition, an excess of solar energy causes thecollector temperature to rise. If the collector temperature exceedsthe switching temperature of the absorber, the output automaticallyadapts to match the reduced heat draw-off. Stagnation temperaturesof max. 145 °C are reached in the collector when the system is at astandstill. When the collector temperature drops, output will increaseagain. In a solar thermal system with switching flat-plate collectors,the formation of steam can be safely prevented with simultaneousadjustment of the system pressure. This helps to protect the systemcomponents (pump, check valves, expansion vessel, etc.) and theheat transfer medium. Reliability and service life are improved.

For economic reasons, the same sizing rules used for conventionalflat-plate collectors apply to switching collectors. However, due to thelow end temperatures, the collector area may be oversized to ach-ieve higher solar coverage.

3.1 Product descriptionVersions■ Type SVKF for above roof installation■ Type SVKG for roof integration

The main component of the Vitosol 100-FM is the absorber withhighly selective coating and ThermProtect automatic temperatureshutdown. It ensures high absorption of insolation and low emissionof thermal radiation at standard system temperatures. A meander-shaped copper pipe through which the heat transfer medium flows isfitted to the absorber.The heat transfer medium absorbs the absorber heat through thecopper pipe. The absorber is encased in a highly insulated collectorhousing that minimises the heat losses of the collector.

The high grade thermal insulation provides temperature stability andis non-outgassing. The collector is covered with a solar glass panelwith a low iron content. This reduces reflection losses.A connection set with connection lines enables easy connection ofthe collectors to the solar circuit pipework. The collector temperaturesensor is fitted in a sensor well (part of the connection set).■ Colour of profile frame: anodised aluminium■ Colour of flashing frame for roof integration: dark blue

Efficiency curveThe optical efficiency η0 and the heat loss factors k1 and k2, togetherwith temperature differential ΔT and the irradiation intensity Eg aresufficient to determine the efficiency curve. Maximum efficiency isachieved when the differential between the absorber and ambienttemperature ΔT and the thermal losses is zero. The higher the col-lector temperature, the higher the heat losses and the lower the effi-ciency.The efficiency curve indicates the typical operating range of the col-lectors. This provides information on the application options for thecollector (see diagram).

Observe chapter "Solar collectors" in this technical guide.

Application options for a 2 to 4-person household:■ New build■ Existing buildings

NoteThe solar thermal system will generate approx. half the energyrequired for DHW heating in a 4-person household.

6.1 Adjusting the system pressure with Vitosol-FMThe pressure set for switching collectors prevents the formation ofsteam. Safety devices for the expansion vessels (stagnation cooleror pre-cooling vessel) are not required. If the pressure is set too low,a small amount of steam can form. This will normally remain in thecollectors and not be pushed into the system. Switching collectorscan therefore be used in systems where the collector array is belowthe DHW cylinder.

Calculating the system pressureIn the case of a Vitosol with switching absorber coating, the systempressure in the collector must be approx. 3.0 bar.

6.2 Pitched roof installation – above roof installationThe Viessmann Vitosol 100-FM flat-plate collector, type SVKF isdesigned specifically for this type of installation.In above roof systems, the collectors and the roof structure are con-nected. At each fixing point, a rafter hook, rafter flange or rafteranchor penetrates the water-carrying level below the collector. Thismeans the anchoring must be completely rain-proof and secure. Thefixing points, and therefore also any possible defects, are no longervisible post-installation. Maintain the minimum clearances from theroof edge in accordance with EN 1991.

Required roof area: a = 2200 mm, b = 2300 mm

Above roof installation with rafter anchors■ This fixing system is suitable for roofs with standard roof tiles,

plain tiles, slate tiles and barrel roof tiles. It is designed for windspeeds up to 150 km/h and snow loads up to 2.55 kN/m2.

■ The fixing system comprises– Rafter anchor– Mounting rails

Clamping brackets– Screws– Seals

■ Guarantees a permanently safe load transmission to the roofstructure. This reliably prevents tile breakages. In regions withhigher snow loads, we always recommend this fixing system.

■ The rafter anchors are available in 2 versions:– Rafter anchor, low tile, 195 mm high– Rafter anchor, high tile, 235 mm high

■ To enable the mounting rails to be secured to the rafter anchors,maintain a clearance of max. 100 mm between the top edge of therafters or counter battens and the top edge of the roof tiles.

■ In conjunction with above roof insulation, secure the rafter anchorson site.When doing so, the screws must reach at least 120 mm into theload bearing wood structure, to ensure sufficient load bearingcapacity.

■ Any unevenness in the roof can be compensated for by adjustingthe rafter anchors.

Criteria for selecting the fixing system:■ Snow load■ Roof with or without counter battens (different screw lengths)

Above roof installation with rafter hooks■ This fixing system is suitable for roofs with standard roof tiles

(except Harz tiles and double-S tiles). It is designed for windspeeds up to 150 km/h and snow loads up to 1.25 kN/m2.

■ The fixing system comprises– Rafter hook– Support brackets for installation on roofs with counter battens– Mounting rails– Clamping brackets– Screws

■ Guarantees a permanently safe load transmission to the roofstructure. This reliably prevents tile breakages.

■ In conjunction with above roof insulation, secure the rafter hookson site.When doing so, the screws must reach at least 80 mm into theload bearing wood structure, to ensure sufficient load bearingcapacity.

■ The rafter hooks can be adjusted to suit various types of roof tilesand to compensate for any unevenness in the roof.

Criteria for selecting the fixing system:■ Snow load■ Roof with or without counter battens

Rafter hooks■ The rafter hooks are fully zinc-plated at high temperature to protect

against corrosion (galvanised, 70 μm coating thickness).■ On roofs without counter battens, the rafter hooks are mounted

directly on the rafters.■ On roofs with counter battens, the rafter hook is secured directly

to the counter batten with a support bracket.

Above roof installation for corrugated sheet roofs■ This fixing system is suitable for corrugated sheet roofs.■ The fixing system comprises

– Fixing hooks– Mounting rails– Clamping brackets– Screws

■ The loads are transmitted to the roof structure in a number ofways, including the fixing hooks and the roof cover. As the loadtransmission can vary greatly, damage may occur when loads areapplied.We therefore recommend fitting additional sheet lead or similarbetween the fixing hooks and the roof cover.

Safety valveWe recommend installing the safety valve above the top edge of thecylinder. This protects the safety valve against contamination, scal-ing and high temperatures. The DHW cylinder does not need to bedrained for work on the safety valve.

Drinking water filterAccording to DIN 1988-2, a drinking water filter should be installed insystems with metal pipework. We recommend installing a drinkingwater filter even with plastic pipework. This prevents the ingress ofdirt into the DHW system.

7.4 Intended useThe appliance is only intended to be installed and operated in sealedunvented systems that comply with EN 12828 / DIN 1988, or solarthermal systems that comply with EN 12977, with due attention paidto the associated installation, service and operating instructions.DHW cylinders are only designed to store and heat water of potablewater quality. Heating water buffer cylinders are only designed tohold fill water of potable water quality. Only operate solar collectorswith the heat transfer medium approved by the manufacturer.

Intended use presupposes that a fixed installation in conjunction withpermissible, system-specific components has been carried out.

Commercial or industrial usage for a purpose other than heating thebuilding or DHW shall be deemed inappropriate.

Any usage beyond this must be approved by the manufacturer forthe individual case.

Incorrect usage or operation of the appliance (e.g. the appliancebeing opened by the system user) is prohibited and results in anexclusion of liability.

Incorrect usage also occurs if the components in the system aremodified from their intended use (e.g. through direct DHW heating inthe collector).

Adhere to statutory regulations, especially concerning the hygiene ofpotable water.
