When you purchase a new boiler, your next step then is to arrange for its installation. The installation cost of your boiler has in most probability been included in the price of your new boiler if you bought it from a professional company specializing in boilers. But you may have to work out an independent installation team if you purchased directly from a boiler manufacturer your new boiler.
Before letting an independent installer of your new boiler start on the installation process, it is advisable that you make sure that he is properly accredited. 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. An installation expert usually would visit your house and make an assessment of the potential site where the boiler will be installed, and they will bring all the required equipment when they come back to install your boiler.
It is important to consider the type of boiler that will be installed when you start arranging the boiler installation, and this is for the reason that various kinds of boilers have different site limitations. 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.
Note that if you remove your old boiler before installing your new one, the supply of your hot water will be interrupted for some period, although not as long as a day to disrupt your operation. Having an installation engineer will make you aware of everything that you need to know like the safety checks so you can start using your new boiler immediately and with the expected efficiency of the unit.
