Boiler

[dorcas5]

Boiler 4 years old hot water has recently become slightly discoloured, pale yellow/orange. Supply to boiler clear, checked hot water from immersion with boiler off, its clear.

Is this the beginning of a corrosion problem? If so what can be done?

If the water has become discoulred then its possible the coil in the hot water cylinder has split,which means water from central heating is mixing with water inside the cylinder.If this is the case then you need a new hot water cylinder. But without seeing what set up you have and doing further checks i couldnt say for certain.

Also, it could be discoloured if you have steel pipework supplying your hot and cold water, instead of copper. But it does sound like a possible split coil, although a filling up and overflowing of the header tank sometimes accompanies this

Thanks for the replies, very much appreciated.
The supply is thro copper pipes, but I don't know how old the tank is

Is it a Fortic cylinder?

The Boiler is a Thermacon 120,000 btu it has an integral cylinder. There have been other problem since its installation, but this has to be the worst.
