“To start with, I liked the system that they had and went on from their really. The installation went fine and i’m really happy with it. The engineer couldn’t have been any better, he definitely knew what he was talking about, what he was doing, the best way to install it and how I can get the best from my system. He explained that the Caernarfon would have the best compatibility for the position and size of the house. I’ve only had it 6 weeks but so far it seems okay. What i like is that Global Energy Systems are just at the end of the phone which is great, they are very helpful.”
