During the sales talk Quatt told me that they would probably know earlier than me of any malfunctioning of the heat pump implying prompt repair. My Quatt was installed quite nicely in November 2024, but started freezing in January 2025 when temperatures were reaching about zero and this happens all the time. Apparently the Quatt does not defrost. I received a workaround to set the gas price low as this results in the Quatt not operating and my boiler doing all the work. Emails about repair requests did not result in meaningful response, and during talks to their emergency number with long wait times (which is not meant for this but the only way to reach them) resulted in unkept promised (not being called back etc.). Half of the times I ended up being transfered to a callcenter where they knew nothing, could do nothing than send a mail to Quatt (without actions). Finally I got a Quatt technician on the phone who told me that there was a problem with a 4-way valve and I received an e-mail that a service appointment would be made. Since then I received a package with some spare parts but there is still no repair date. The result is that I have a dysfunctional Quatt now for over 4 weeks without an indication when this will be rectified.

Works great. Unstalation was perfect

Everything went fine until the day Quatt installed the heat pump. Two friendly Polish installers arrived at our house around 9 am, and we expected the job to be done within 4-5 hours. Unfortunately, these guys worked very hard till 6pm without finishing their job. They mentioned there was an issue with the product and tried to contact Quatt's support center by phone, but they struggled to get through. Around 6 pm, the installers told us that they couldn’t finish the job and left without fixing our radiator. They asked us to call Quatt to resolve the issues. WTF!
As a result, our heater wasn’t functioning properly, and we were left with a cold house for over a week. We called the number 0202610170 for assistance, and they always promised to "call us back as soon as possible," but we never received a callback. Additionally, whenever we tried to get help, they asked us to hold on while they connected us to their colleagues, but they consistently hung up after a few seconds. We’ve been unable to reach them.
After a week and calling them everyday, a support manager finally reached out to arrange for someone to fix the heater. The following day, a Dutch technician came to repair the heat pump. Everything seemed fine when he left, but we soon started hearing a lot of noise and vibrations in the living room and bedroom, as the unit is located on the flat roof of an additional living space. We also discovered a leak in the radiator.

So now, the worst part is our radiator not working at all and we are either being tortured by noise or cold. We paid ~6k EUR for people to come our house, ruin our heater and leave a mess.

A few messages for who are considering using heat pump.

Please make sure to find companies with strong technical support and customer service teams. I can't tell to the quality of Quatt's products overall, but I can say that their back-office team is not strong enough to support us—at least not during our experience. They tested our patience under the winter weather.

We always want to support young businesses, but we didn’t make the best decision this time. So, if you're considering Quatt products, it might be better to wait until they’ve matured as a business.

Thanks for your patience. I’m doing my best to control my anger while writing these words.

From beginning till the end everything was according to plan. Planner Roger explained me all details I cared in nice manner. Installer was very helpful and nice. Department help me with problem solving. I have very positive experience.

We installed Quatt heat pump a month and a half ago. Inspite of the heat pump, our gas price is too high for last month. We were promised that whenever required, we can get expert on phone. Inspite of trying multiple times, no one bothered to give a call back. Looking at such a high gas price and really poor customer service, we have started thinking if it was even a good decision to go for quatt heat pump.

Watch out to these scammers.

They were so nice to advice us regarding the installation on the roof but once they got the 100% money wired to them they start saying it is not possible to install the pump on the roof for safety reason. They have done it many times for other clients. we asked for a refund and they emitted a credit nota of 10.174€ on 17th October … today is 11th November no track of that money neither a proof of payment. Customer service is non existent short hours never reply to an email I manage to talk only twice in a month of trying to get in contact.

Be careful when arranging a house inspection from Quatt, as they will just take the money and then say that the installation is impossible.

Then, despite stating on the website that you will get a refund, you will hear nothing from them: no answers to emails or phone calls.

This is what happened to me two weeks ago. During the house inspection, a guy said that the installation was impossible and that he had to check it in the office. I still haven't got anything from them: no email with decision, no refund.

Everything went as discussed during the initial meeting. Perfect installation. Waiting for the summer to see the heatpump in action.

Clear communication, good service and professional installation

Alles perfect verlopen. Installatie, after sales, prima.

Everything was going well with Quatt, from the first contact until the final installation.

From consultation to installation a very nice and seamless process. Tidy and fast work. The guys even fixed an old issue I had with previous work done by... Khmmm... Kemkens ..

If I could complain about something is the look of the plastic covers of the pipes inside the house. As it's the same as on the outside it's a bit ugly looking. And as it's not a small thing it's a bit of an eyesore that we have to figure out how to hide. It could be a bit more elegant.

Quaat doet wat zeggen. Van

Everything was well organized. The installation was done with very good knowledge, clean and speed. The system works to my satisfaction even there were no very cold days until now.

Very poor costumer service. My Quatt doesn't work and despite several calls no response from Quatt yet. It's cold in my house for a whole day already. Call center is only able to send message to quatt and quatt is not responding at all.

Perfecte logistiek.

Quick Installation, very good function, much better, than I expected with my house from 1930.
Very nice Company!

Convenient and easy to manage.
Installation was neat and communication precise.

Super apparaat, stil, efficient en top installatie

Excellent and quick installation for a good price and with good saving in gas (5 stars). Very poor/disappointing client service/operational support afterwards. Having an issue with the software and have repeatedly asked for help. Several replies we're given, but none of them worked. In the end they don't reply at all (1 star). Average of 3.
