Depending on the job's specifics, installing a new boiler could take anywhere from six hours to four days.
Turn off your boiler before the plumber or heating specialist arrives. This ensures that it has had the time to cool down, allowing your service technician to begin working on your problem as soon as he comes. In addition, it would be beneficial to ensure an unobstructed passage leading to the boiler, the radiators, and any connected systems.
Any repair or maintenance that must be done on the boiler should not be complicated if it is conveniently accessible. For the plumber to service the boiler, the door to the cabinet must be able to be opened, and there must be at least 700 mm of clearance between the front of the boiler and any obstructions.
First, you need to prioritise having your boiler checked by a professional once a year. A service performed once a year is sufficient to keep your boiler in good working order and reduce the amount of wear over time. It is usually optional to perform maintenance any more frequently than this.
