Regular boilers are now largely bought as replacements for homes with an open-vented heating system (i.e. supplied by means of a feed and expansion cistern in the roof space, meaning the system is open to air). Like system boilers, they work on the principle of stored water

Bosch Condensing Boilers for High Efficiency. Meticulously designed with the latest advancements in technology and hydronic boiler efficiency, Bosch condensing boilers also features a secondary heat exchanger designed to recover the heat waste normally expelled through the flue.
Today there are gas, electric, cast iron, condensing and modulating models that have an AFUE (annual fuel utilization efficiency) rating 85% or even more, thus achieving better efficiency with a whole bunch of improved features. AFUE is a parameter that is used for comparing and testing two different boilers under similar conditions.
Gas-fired condensing boilers are a new type of autonomous heating equipment for homes and apartments. They boast high efficiency much higher than that of conventional boilers. This efficiency level is achieved thanks to the use of heat generated by the combustion of liquid and thanks to the use of energy generated by gas combustion.
Hence, the name condensing gas boiler. The other facet contributing to the high efficiency of condensing gas boilers is the combustion air fan can fully modulate its speed as compared to a single stage, full on or off, device found on typical mid-efficiency boilers.
2019-8-26·Saving energy helps you save money on utility bills and protect the climate by reducing greenhouse gas emissions. ENERGY STAR certified boilers have annual fuel utilization efficiency (AFUE) ratings of 87% or greater for oil boilers and 90% or greater for gas boilers. AFUE is the measure of heating equipment efficiency.
