Had Firmus Heat in after a recommendation to replace my regular boiler to a combi boiler, Great service very professional and showed me how the new hive thermostat worked and even set it up on my phone, They Removed all old tanks pipework and wiring, done a great job on the brickwork around the boiler flue, you Would not of known they had been there when they finished as they even hoovered up after them Great Service would definitely recommend i will be getting them to fit a water softener in the next couple of weeks
