Piping -  Your new “A” rated condensing gas boiler may require a larger gas pipe dependent on the distance from the gas meter, current pipe size and the amount of gas appliances served by the current gas line. In addition if you are planning on relocating the new gas boiler, provisions will have to be made for re-connection of the existing heating system piping to the newly installed gas boiler. Floors coverings may have to be temporarily removed to allow the routing of piping to serve the boiler in its new location.

Condense - Your new high efficient boiler will require a means of discharging its water vapour by product to a suitable drain or soak away. 

Boiler Flue - The length of run and Flue terminal location are two very important factors to be considered when choosing you boiler location. A boiler located internally with no direct access to an outside wall will require addtional flue lenghts and components and this will impact your expenditure.

Space Requirements - Boilers come in all different sizes and with that their minimum space requirements vary greatly. It’s Important to note the minimum space requirement for service, repair and Installation.
