Gas boiler fitting is a very complicated process that requires proper knowledge, skills, experience and license, of course. Before hiring a professional it is also highly important to check whether you are to have a special permit with local authorities. If you don’t do it, you risk spending much time and money, as in many locations they have special regulations about the boiler type that can be fitted based on carbon dioxide production and efficiency levels.
Today there are three main types of gas boilers offered on today’s market:
If we speak about their fitting, they have different levels of difficulty.
Conventional ones require the fitting of a tank, a cylinder and a boiler itself. System boilers should be attached to the water and gas lines, according to the guidelines that are provided by the manufacturer of the chosen appliance. In case of system units, one should also pay special attention to proper venting in order to prevent the release of dangerous gases during the combustion.
Sealed system units don’t require the fitting of a separate tank, as the majority of vital parts are already contained in a boiler. However, some appliances still require the installation of a cylinder along with the boiler fitting. Water and gas lines should be tapped as well.
Combination (combi) boilers do not need a tank or a cylinder. Such systems should be installed to the provided directions and then attached to the lines.
Though most manufacturers provide detailed instructions, it still doesn’t mean that the units can be easily installed by an inexperienced person. To avoid possible negative consequences and complications, we suggest hiring a professional with experience in installation procedures.
It is hard to say there is one certain amount of cash that is spent by everyone. There is no fixed sum, but there is a list of approximate expenses:
There is also a number of additional factors that influence the installation costs (they can go higher or lower):
In any case, there is always a chance to cut down on additional unexpected expenses, if you hire a professional, who’s well-acquainted with the gas boiler fitting procedure.
