Dale and his apprentice did a great job and took away the old stuff. I will, indeed, be writing a review on google and trustpilot and, if you have a preferred review site, I'll copy it to that too. Dale took time to explain the system and, what I was very impressed with, both he and his apprentice asked permission to enter the rooms to access the radiators and the meter. I'm also happy with the way Heatable responded to the issue we had and want to say thanks. Good customer service is, I hope, always appreciated and goes a long way to allowing customers to recommend a company with confidence. Anyhoo, that's all I wanted to say, except that I've already told Google assistant to switch the heating on and off, change the temperature and marvelled as it was done in seconds. Very cool! (no pun intended)
