Fantastic service. I highly recommend this company. What I appreciated was the quick responses, and the technical capability of Federico. As an engineer I get tired of people only interested I selling. Q-Tec was not like this. They took the time to recommend a solution AND. Support it with good solid science.
Highly recommend this company.

De warmtepomp die Q-tech ons aanbevolen heeft werkt top ! Zij werken alleen met topkwaliteit . Ons zwembad warmt met 1 graad per uur op - beloofde resultaten worden gehaald. En we kunnen altijd op het team rekenen als er problemen opgelost moeten worden. Dan zetten ze alles opzij en lossen zij het probleem op. Dankjewel voor jullie service !

5 Stars. There are 5 of us and we are very happy with the hot water. After searching for information for almost a month on low-consumption hot water systems, we decided on b. heat only hot water. Delivery in just 3 days from the web order.

Delivery was delayed a day due to the height of the package but then everything was perfect.

Thank you :)
