to most people as “condensing boilers” are essentially
the same as other fan-flued boilers with only a few slight differences
setting them apart. A high-efficiency boiler has either a secondary
heat exchanger or one with a larger surface area.
condensing boiler is more efficient due to it’s ability to extract
more heat from the flue gases normally lost to the environment through
the flue system.
flue gases, which heat the heat exchanger pass through the primary
heat exchanger and exit at approx. 250 degrees C. The heat enters
the secondary heat exchanger or larger area, to release more of its
simple process means that much less gas is required to produce the
same amount of heat. Annual fuel savings of at least 30% are often
enjoyed by the end user.
Built in pump, expansion vessel, pressure relief valve and pressure
The boiler is supplied pre-wired and pre-plumbed.
The boiler can be connected to either low pressure open vent cylinders
or mains pressure unvented units.
There is less pipework
There is no feed and expansion cistern in the loft space.
