Poor
Due to incorrect advice, a product was sold that does not at all fulfill the advertised and promised properties and fits the object. It's great when the previously warmest room now remains cold because the underfloor heating is no longer warm. Also, the heat pump has a much too high power consumption. After only two months, it has already consumed more than the seller has calculated for the whole year. Either it is a defect or not the right system for the house. Presumably, however, there was the biggest commission for it. In addition, there are many defects due to the installation of the heating system and several unsuccessful attempts to fix them, or it is also claimed that there are no defects.
Also a complaint due to missing and poorly executed insulation, a faulty pipe installation and a defective wall breakthrough is rejected with the statement that there are no regulations or standards and it is correct as it is. I have searched for a very long time for what there are no standards / regulations in Germany and now finally found out thanks to Thermondo.
For several weeks there was also no feedback on calls, emails and registered letters. Based on my personal experience, I can therefore only advise everyone to rather take a trustworthy local heating engineer for his project.
The one star is still too much for me but giving less is not possible. The only thing that runs in this project is the electricity meter and the water from any leaks.
There are certainly also installers at Thermondo who like their job and do it right but unfortunately they were not with us.

In June 2022 installation of the heat pump for the KW 37/38 get communicated. Since then, zero information more, despite multiple requests. Now is week 37 and we feel slowly fooled. Not to be recommended, unserious and not professional.

Addendum March 2023: the organized irresponsibility, accounting catastrophic, even registered letters to management are ignored. One tells ..umpteen people on the phone over and over again the same thing, the next knows then again of nothing. A disgrace !

Consultation, scheduling, installation and follow-up work were carried out quickly, very cleanly and with high quality at a very good price-performance ratio. I have therefore recommended Thermondo to my acquaintances.
My later e-mail inquiry about practical aspects, on the other hand, has not yet been answered. Only 14 days after my inquiry, two telephone calls were made during my absence. Another telephone inquiry to the customer service has so far remained without result.

From the sales consultation to the installation of the system, we are extremely satisfied.
The regulation of the heating e.g. day and night temperature was not shown to us, on the request for the sending of a user manual to be able to do just this ourselves, we were referred to the installation company, which has contacted by phone, not reached us and that was it. We still want a user manual for our heater, that is certainly even our right ...

The advice and installation of the heat pump were very good. The installers have worked very cleanly and well.
Unfortunately, the cover and the heating element are still missing. The most annoying thing is unfortunately the non-functioning WiFi module.
So I always have to go to the technical room to read the data. The communication with Thermondo is not good. No feedback despite calling several times. Very sad!!!

The system has a good heating performance (price, performance) consumption only hot water about 10 KW / h to minus 14 degrees about 50 KW / h until now on average about 25 KW / h. We had gas before because the consumption was somewhat higher. Particularly is, that one can hear the plant outside hardly. The electricity for the heating comes from our solar cloud storage. Costs for cloud storage (heating and electricity consumption) and electric car and Vollservieses at Thermondo together about 180.00 € Mtl. a bargain in today's time.
