arrow What’s a condensing boiler and how does it work?

Condensing boilers are highly efficient. They use less fuel and have lower running costs than other boilers. Higher efficiency levels are made possible by extracting heat contained in the combustion gases, which would otherwise have been lost to the atmosphere.

The condensing works better when the return water is at a lower temperature than conventional systems. The boiler is designed to transfer the temperature from the hot flue gases to the return water; this action causes the flue temperature to condense,

The good thing about condensing boilers is when you see the plume of water vapour you know you are saving money and reducing harmful co2 emissions.

Locating the condensing is important as the pluming can be perceived as a nuisance, especially if it is blowing towards your neighbour’s property or close to windows or doors.

When installing central heating boilers it is important to ensure that the system is flushed to remove dirt from the pipe-work and radiators.

It is also important to install a chemical cleanser to remove flux and to remove grease that is used to protect the radiators from rusting on the inside while awaiting installation.

On old systems take great care to remove any sludge that has formed over the years due to incorrectly installed or leaking pipes. It may be more economical to replace the whole system depending on its condition.

After cleaning the inside of the system a central heating protector should be added to prevent corrosion and lime from occurring.
