installation method
Theterm“groundsource”coversfourdifferentheatsources:rock,surfacesoil,groundwaterandlake.
Ground waterA viable energy source for any building where ground water is easily accessible.
Ground water can also be utilised as a heat source since ithasa temperatureofbetween4and12°Call-year round.Theheatpumpcollectsstoredsolarenergyfromthegroundwater.Normally, there is one well for drawing up water and one forreturningit.
Lake collectorCost-effective installation for lakeside homes.
Ifyourhomeisbuiltbesideawatersourcesuchasalake,heatfromthelakewatercanbeextractedusingasurfacesoilcollectoranchoredtothebottomofthelake.
Rock - using a ground probeIdeal for refurbishment or adaptation from a fossil fuel heating system.
In the lower subsoil of the so-called “near-surface geothermallayer” lies a heat source with an almost constant temperaturethatcanbeutilisedallyearround.Theheatpumpcollectsstoredsolarenergyfromacollectorinaholedrilledintotherock.Thedepthoftheholecanvarybetween90–200metres,dependingon thesizeofheatpumpselected.This typeof systemcanbeused for all possible building types, large or small, public orprivate.Itrequireslittlespaceandthegroundprobecanbedrilledinthesmallestofgardens.
Surface soil - using a surface collectorCost-effective energy collection.
During the summer, solar heat is stored in the soil. This iseither directly absorbed as insulation or as heat from rain andthe air from the near-surface layer of the soil. The heat pumpcollectsthisstoredsolarenergyfromaburiedcollector.That is,a hose filled with anti-freeze, and buried at a depth of about80 – 100 cm, the length of the hose varies between 250 and400 metres, depending on the size of heat pump selected.Using this energy for heating is a cost effective method. Thehighestyieldcanbeobtainedfromsoilwithahighwatercontent.
F1345 is extremely efficient thanks to a highly effectivecompressor in well dimensioned refrigerant circuits. Internallyinstalledlowenergycirculationpumpsandflexhoses(notbrinepumpfor40or60kW).Thebrinerespectivelyheatingmediumcircuitsareconnectedfromtherearof theheatpump.Particlefiltersupplied.Theheatpumpcanbeconnectedtoanoptionallowtemperaturedistributionsystem.e.g.radiators,convectorsorunderfloorheating.F1345isequippedwithacontrolcomputerforoptimumandreliableoperation.AlargebacklitTFTdisplayshowsinformationaboutstatus,operatingtimeandalltemperaturesintheheatpumpaswellascertaininformationaboutanyslaveheatpumps,incolourusingiconsandtext.F1345isconstructedonarobustframewithdurablepanelsandeffectivesoundproofingforthebestpossiblecomfort.Allpanelsareeasytoremoveforeasyaccesswheninstallingandforservicing.

F1345 consists of two heat pump modules (cooling module),circulationpumpsandcontrolsystemwithpossibilityofadditionalheat. F1345 is connected to the brine and heating mediumcircuits.
Intheheatpumpevaporator,thebrine(watermixedwithanti-freeze,glycolor ethanol) releases its energy to the refrigerant,whichisvaporisedinordertobecompressedinthecompressor.Therefrigerant,ofwhichthetemperaturehasnowbeenraised,ispassed to thecondenserwhere itgivesoff itsenergy to theheatingmediumcircuit and, if necessary, to anydockedwaterheater.Ifthereisagreaterneedforheating/hotwaterthanthecompressorscanprovide it ispossible istoconnectanexternalimmersionheater.

Tosimplifytransportandservice,theheatpumpcanbeseparatedbypullingthecoolingmoduleoutfromthecabinet.
Seetheinstallermanualforcomprehensiveinstructionsabouttheseparation.
Leave a space of 800 mm in front of the heat pump.Approximately 50 mm free space is required on each sidein order to open the side hatches. The hatches do not needto be opened during service, all service on F1345 can becarried out from the front. There must be at least 300mm offree space above the heat pump. Leave space between theheat pump and wall behind (and any routing of supply cablesandpipes) to reduce the riskof reproductionof any vibration.

Inspection of the installationCurrent regulations require the heating installation to beinspected before it is commissioned. The inspection mustbe carried out by a suitably qualified person and should bedocumented.Theaboveappliestoclosedheatingsystems.Iftheheatpumpisreplaced,theinstallationmustbeinspectedagain.
Guideline values for collectors
Type Surface ground heating, recommended collector length
Ground-source heating, recommended active drilling depth

Forusewith40x2.4PN6.3PEMhose.
This are rough example values. On installation the correctcalculationsmustbemadeaccordingtolocalconditions.
Thelengthofthecollectorhosevariesdependingontherock/soilconditions,climatezoneandontheclimatesystem(radiatorsorunderfloorheating).
Maxlengthpercoilforthecollectorshouldnotexceed500m.
The collectors must always be connected in parallel with thepossibilityofadjustingtheflowfortherelevantcoil.
For surfacesoilheat, thehoseshouldbeburiedatadepthofabout1metreandthedistancebetweenthehosesshouldbeatleast1metre.
Forseveralboreholes,thedistancebetweentheholesmustbeatleast15m.
Ensurethecollectorhoserisesconstantlytowardstheheatpumptoavoidairpockets. If this isnotpossible,airventsshouldbeused.
As the temperatureof thebrine systemcan fallbelow0°C itmustbeprotectedagainst freezingdown to -15 °C.One litreofreadymixedbrinepermeterofcollectorhose(applieswhenusingPEM-hose40x2.4PN6.3)isusedasaguidevaluewhenmakingthevolumecalculation.
Control, generalThe indoor temperature depends on several factors. Sunlightand heat emissions from people and household machines arenormallysufficienttokeepthehousewarmduringthewarmerpartsoftheyear.Whenitgetscolderoutside,theclimatesystemmustbestarted.Thecolderitisoutside,thewarmerradiatorsandfloorheatingsystemmustbe.
The heat pump is controlled by built-in sensors for flow andreturnbrinetemperatures (collector).Brinereturntemperaturescan, if so required, be limited to a minimum (e.g. for groundwatersystems).
Control of the heat production is performed based on the"floatingcondensing"principle,i.e.thetemperaturelevelneededforheatingataspecificoutdoortemperatureisproducedguidedbycollectedvaluesfromtheoutdoorandflowsensors.Theroomtemperaturesensorcanalsobeusedtocompensatethedeviationinroomtemperature.
F1345canbedockedtoanexternalunitwith itsownheatingcontrols. In that case, the heat pump delivers heat up to afixed temperature level. This is known as “Fixed condensing”.Theautomaticheatingcontrolsystem is thencontrolledbytheexternalunit’sregulationdevice.
