On the contrary, Even -15 degree is a good condition for Palm air source heat pump. It can even make heating during minus -20 degree, which is proved by Palm real customer feed back. Palm Inverter air source heat pump can make heating during -25 degree.
Recent Feedback by our customers in scandinavian countries told us that they have very cold climate this winter. Someone scream that new ice age is coming! This is the coldest winter for 30 years. Most place come to lowest -20°C, some place lower to -25°C. Most heat pumps are frozen and stop working. The electricity and gas bill increase too high in this winter. How to survive this winter with heat pumps? Very enoucrage news from many countries said that Palm heat pumps are still working very well and give warm to home. Palm heat pumps are equipped with most advanced defrost technology and antifreeze technology and already run in real field working for several winters. The practice approve Palm heat pump can work in scandinavian countries for whole cold winter.

Ich habe eine 3Aqua-19 installiert. Ich betrachtete es mehr als ein Abenteuer. Schließlich wohne ich in Muldenhammer. Dazu gehört der kälteste bewohnte Ort von Deutschland, Morgenröthe-Rautenkranz. Und die vorhandene Öl-Heizung mit Radiatoren stellte auch keinen Idealzustand dar. Also Test unter Extrembedingungen. Aber mich reizten der Preis und die sehr geringen Installationskosten. Die Inneneinheit enthält neben 2 Wärmetauschern bereits einen Heizungswassertank (mit 2 Elektroheizstäben je 3KW) und einen Brauchwassertank mit Elektroheizstab für Legionellenschaltung. Das Ergebnis war verblüffend. Bis -20°C arbeitete die Wärmepumpe ohne jegliche Unterstützung durch die Heizstäbe. Auch die Warmwasserbereitstellung erfolgt in kürzester Zeit.
Fazit: Alle meine Bedenken lösten sich in Luft auf. Diesen Schritt habe ich nicht bereut.
English version: I have an installed 3Aqua-19. I looked at it more as an adventure. Finally, I live in Muldenhammer. This is one of the coldest inhabited place of Germany, Morgenröthe-Rautenkranz. And the existing oil heating system with radiators also provided no ideal state dar. So test under extreme conditions. But I was attracted by the price and the very low installation costs. The indoor unit contains two heat exchangers already Heating water tank (each with 2 x 3KW electric heating), and a hot water tank with electric immersion heater for legionella. The result was amazing. To -20 ° C, the heat pump to work without any support from the heating elements. The hot water supply is in a very short time.
Conclusion: All my doubts vanished into thin air. This step, I have not looked back.
Besten Dank Dipl. Ing. (FH) Roland Döhler

Mr. Heikki said:
It’s nice, that you are interested about my pumps operation.
1. >Outside air temp is now -13 degrees Celsius
2. The pump is connected with an old water central heating with radiators. The room size is about 150 m2.
3. Outdoor units defrosting is working properly, from my mind even too often. When temp was higher, a little under zero, there was some frost, but now nothing.
4. Triaqua can reach target water temp wery well. More emails: Hi, Here are some photos here. We have two kind of radiators, as you can see. The low ones are hidden unde the benches.
More emails from customer:
Hi,I made a little test.
We have now -24C and I turned the old wood heating system off and started Triaqua.
After a while temp had risen 1 degree. So that it really gave warmth. After that I returned to the wood heating, because I think, that it is cheeper in these circumstances.
