Buying a new boiler would also mean you have to install it. If you bought your boiler from a professional boiler specialist company, in most probability the boiler installation is already included in the price of the boiler. But you may have to work out an independent installation team if you purchased directly from a boiler manufacturer your new boiler.
If you are planning of hiring an independent engineer to install your new boiler, it is recommended that the person has proper accreditation before working on your unit. Note that a badly installed boiler can be very dangerous because of the gas that will come out from the unit, and so it is advisable to avoid having your boiler installed by an unqualified engineer. The process of installation by an expert installer would start in the assessment of your area where the boiler will be installed, and then when installation time comes, all the necessary equipment and tools will be brought to properly conduct the job.
Since different boiler types will have different limitations where they will be installed, it is advisable that the first thing you need to know is the kind of boiler being installed as you arrange the boiler installation. The size of combi boilers are small enough to be placed in most dwellings, while an open vent boiler, with its two separate water tanks, will need enough space for the tank for cold water storage and for the other tank for storage of heated water. The location of these two types of boilers vary in the sense that an open vent system is to be placed close to the tanks to maximize its efficiency, while the combi boiler system is to be placed near to the main sources of water where heating occurs. It is most cost effective for you to install the new boiler to the place where the old boiler is located since the water pipes are already positioned in that place, and you avoid doing other works that will make you spend additional money.
Take note that in order to avoid interruption of your hot water supply in the household, do not remove your old boiler before installing the new one, and in this case you will have to make a little sacrifice within the day. After installation is done, the installation engineer has to brief you with the necessary safety checks before starting and using your new boiler so that safety is ensured and efficiency of the system is assured.
