Heating with air and geothermal heat - Viessmann

Heat pumpsVitocal 350-AIdeal for modernisationThe Vitocal 350-A air source heat pumpmakes modernising easy. The additionalvapour injection during the compressionprocess (EVI cycle) enables a flowtemperature of up to 65 °C. It is thereforeideal for older heating systems with existingradiators. For this, the heat pump draws itsenergy from the ambient air.High DHW convenienceSubject to system version, a higher flowtemperature enables a water temperatureof up to 55 °C inside the DHW cylinder.This allows the Vitocal 350-A to deliver aparticularly high level of DHW convenience.The Vitocal 350-A achieves the high flowtemperature of 65 °C, even at outsidetemperatures of -10 °C.RCD guarantees efficient operationRCD stands for Refrigerant Cycle Diagnosticsystem. In the Vitocal 350-A, it is responsiblefor permanently monitoring the refrigerantcircuit. This, in conjunction with the electronicexpansion valve (EEV), ensures the highestefficiency at every operating point. Alongsidethis, important operating parameters aresaved and called up, when required, fordiagnosis, optimisation, energy statementsand to calculate the seasonal performancefactor (SPF).Spot onIf the heat pump is installed outside, the heatneeds to be "transported" to the interior of thehouse. In this, you can rely on Viessmann'scompetence in heating systems. All thepipework required for routing underground,as well as the entire range of accessories,are provided from one single source, and areperfectly matched to one another.13242567Vitocal 350-A1 Intake side2 Discharge side3 Evaporator4 Radial fan5 Electronic expansion valve6 Evaporator for intermediate injection7 Hermetically sealed scroll compressorwith vapour injection (EVI)
