I highly recommend Heatable. Was such an easy smooth process from placing our order for the boiler to getting it installed it didn't even take long. Heatable kept us informed and called us with all the next steps and timings of installation and also who will be coming to fit the boiler. The guys who came in were also great Henry and Paul. Paul was very informative and gave us all the information we required once he fixed the boiler and also fixed our hive device in for us. They also cleaned all the mess and left the area as they found it before leaving. We love our new boiler and couldn't recommend heatable more very professional. Thank you!!!
