Vorwort
Diese Seite beschreibt den Umbau von einer Viessmann Atola 11kW Gasheizung auf eine Panasonic Aquarea Wärmepumpe WH-MDC05J3E5.
Der Bestand
Das Haus
- Reiheneckhaus in Oberbayern
- Baujahr 1990
- 2016 von uns erworben
- Erdgeschoß, Obergeschoß und Dachgeschoß mit zusammen 131 m² Wohnfläche plus Keller
- Erdgeschoß Wohnzimmer, Küche, WC
- Obergeschoß drei Zimmer, Bad
- Dachgeschoß ein Zimmer, Bad
- Wände aus 30 cm Hohllochziegel
- Ursprüngliche Dämmung Dach ca. 4 cm Engelshaar Glaswolle + 2 cm Rigipsplatte
- Unten Bodenplatte 1 cm Styropor + 7 CM Betonestrich
- Dach 26° Neigung Süd-Südwest/ Nord-Nordost
- 9,3 kWp PV Anlage auf dem Süddach
Die Heizung
- 11kW Viessmann Atola Niedertemperatur Gasbrenner BJ 1990
- EG: 3 Heizkörper in Reihe (90x55 22, 140x55 22, 60x55 10)
- OG: 5 Heizkörper in Reihe (70x55 20, 70x55 33, 60x55 22, nachgerüstete FBH (2016), Handtuchheizkörper (2016), 70x55 20)
- DG: 2 Heizkörper in Reihe (80x55 33, 80x55 33)
- Keller: 1 Heizkörper nachgerüstet parallel (140x90 22)
- Rauschfreier Volumenstrom 540 l/h
Die Idee
Heizung
- Einbau einer 3,5kW LLWP im EG im August 2022 wegen von Russland erzeugter Gaskrise
- Planungsbeginn Umbau auf Wärmepumpe trotz miserabler Hydraulik im Herbst 2022
- Beim Gasbrenner die Düse auf 5kW Heizleistung ausgelitert
- Stromanschluß des Gasbrenners auf Steckdose umgebaut und einen Tasmota WLAN Stecker dazwischen gesteckt um über den Stromverbrauch das Taktverhalten im Homeassistant zu protokollieren.
- Am 13.12.2022 bei minus 14 Grad war der Brenner immer noch am Takten - somit war klar, das 5kW Heizleistung ausreichen müssten.
Hydraulikschema
Obwohl laut Wikipedia Einrohrheizungen schon seit den 1980ern kaum noch eingebaut wurden, hat der damalige Errichter trotzdem eine beauftragt - der drei Reihenhäuser wurden ja nur vermietet. Die anderen Häuser der Straße wurden von Eigenheimbewohnern gebaut - da findet sich Fussbodenheizung und Zweirohrkreise bei Heizkörpern. Ein meiner Meinung nach weiterer Grund, warum sich Gesetzgeber ins Baugewerbe einmischen müssen, um Mindeststandards durchzusetzen.
Die Einrohrheizung ist einfach Mist:
- Geringer Volumenstrom
- Bei Verwendung eines Überstromventils geht wegen des hohen Gegendrucks der Einrohrheizung bei Heizbetrieb das Volumen durch das Ventil direkt in den Puffer
Somit wurde der alte 200l WW-Speicher als Reihen-/Abtaupuffer eingeplant wie hier beschrieben mit elektrischem Umschaltventil.
Dabei wird ein zweites 3-Wege Ventil zwischen Vorlauf Heizkreis und Vorlauf Reihenpuffer eingebracht, um bei Abtaubetrieb einen Kurzschluß von der Wärmepumpe zum Reihenpuffer herzustellen. Im Heizbetrieb läuft der gesamte Volumenstrom durch den Heizkreis und dann durch den Reihenpuffer.
Das 3-Wege Ventil wird durch das Abtausignal der Jeisha umgeschalten (AB - Reihenpuffer Vorlauf, B - Heizkreis Rücklauf, A - Wärmepumpe Vorlauf).
Dämmung
- Beim Umbau vor dem Einzug mussten schon die Fenster im EG getauscht werden - das passierte zum Glück 3-glasig.
- Sonst war die Dämmung des 1990er Zustands nur das mindeste.
PV
- 9,3 kWp Anlage kam in 2019 und Dank PV-Forum mal was selbst mit Vorwissen geplant
- Das Süddach ist komplett voll und die Technik für 2019 top.
Umsetzung
Dach
- Beim Umbau vor dem Einzug 2016 mit 16cm Mineralwolle gedämmt und wo möglich mit 40cm (Dachspitz und gefangene Räume über den Lauf der Zeit)
Fenster
- Alle Rolladenkästen aufgemacht, sauber gemacht, Bänder getauscht und mit 40mm Armaflex nachgedämmt
Wärmeverteilung
- Bei allen Heizkörpern vor dem Winter 2022 die Thermostate mit Blindstopfen ersetzt
- Den thermischen Abgleich mit den Einrohrhahnblöcken gemacht
Somit konnte der Volumenstrom auf 720 l/h rauschfrei erhöht werden
Installation Wärmepumpe
- Rückbau der Zirkulation
- 300l TESY Speicher unter der Küche aufgestellt, das Warmwasser kommt nun ohne Zirkulation in ca. 3 Sekunden in der Küche, in den Badezimmern nach ca. 10 Sekunden
- Thermosiphons beim WW-Speicher verbaut
- Drei Wärmemengenzähler: Heizen, WW-Bereitstelung und WW-Verbrauch
- Alten 200l WW-Speicher als Reihenpuffer verbaut - der Kurzschluß beim Abtauen wird durch ein weiteres, von der Jeisha gesteuertes, Afriso 3-Wege-Ventil geschalten.
- Gasbrenner entsorgt
Steuerung & Co
Ziele sind:
- möglichst lange Laufzeiten des Kompressors
- konstante Innenraumtemperatur bis in den Abend
- Ausnutzung der PV und höheren Quelltemperaturen durch eine Überhöhung tagsüber und einmalige Warmwasserbereitung um 13 Uhr
Statistiken
Ohne Messwerte und deren Auswertung keine Entscheidungen!
Wärmepumpen-Verbrauchsdatenbank
Steuerung
Die WP Heizungssteuerung läuft mit der Wassertemperatur geführten Heizkurve. Das Steuergerät ist an zentraler, schattiger Stelle im Wohnzimmer montiert und damit wird die Raumtemperatur gemessen.
Die Heizkurze bestimmt anhand der Aussentemperatur den Vorlauf und somit den Energieeintrag - wenn dieser passend nachgeführt wird, bleibt die Temperatur im Haus konstant.
Die Heishamon Rules
- schalten die Warmwasserbereitung um 13 Uhr ein, setzen anhand der Außentemperatur das Warmwasserziel, schalten bei warmen Temperaturen in der Nacht die WP komplett aus und drosseln die Wasserpumpenleistung in der Nacht (timer10)
- schalten beim Ende der Warmwasserbereitung wieder zurück auf Heizbetrieb ohne den Kompressorlauf zu unterbrechen (on @DHW_Power_Consumption)
- kümmern sich um das Eindrosseln der Jeisha per Flüstermodus und Laufzeitverlängerung per Vorlauftemperaturverschiebung (on @Main_Outlet_Temp und on @Main_Target_Temp)
Alles andere macht die Jeisha Steuerung.

Messfehler Stromverbrauch
Wenn man dem "Stromzähler" der Aquarea vertraut und dem daraus resultierendem COP, dann ist man enttäuscht, wenn man am Saisonende auf die Stromrechnung kuckt...
Mit höheren Wärmeleistungen wird der Unterschied sogar noch größer...
Heizwasservolumestrom beim Umschalten auf den Pufferspeicher
Bei gleichbleibender Pumpenleistung verdoppelt sich der Volumenstrom, wenn das Abtau-3-Wege-Ventil auf den Pufferspeicher umschaltet.
