Alex from Think Gas did a great job. The system works as expected and he did a very tidy job leaving no mess. This was a major installation, and Alex promptly dealt with a few teething problems until the system settled down. We would recommend Thinkgas, and will continue to use them for ongoing maintenance of the system.
