The majority of central heating boilers sold today replace low efficiency boilers. An important point to take into account is that brick built chimneys along with thin wall aluminum systems do not withstand the aggressive condensate produced by the condensing boilers.

Many apartment buildings are equipped with one central floor standing boiler providing heating and hot water to all apartments via the central heating system. More and more housing associations provide their tenants with an individual heating system.

Changing the flue systems to one which is suitable for modern boilers is in many cases an expensive method and brings a lot of inconveniences for the inhabitants.
