The water in the f&e tank of an open system is boiling hot.

The water level in the f&e tank is not rising but because the temp of the water is so hot there is a massive condensation problem.

Radiators seem to be heating

Hot water is fine.

Any suggestions on the fault with the f&e tank would be great.

is it definately not pumping over through the expansion pipe above the tank? has the pump been changed recently ie. maybe fitted wrong way roung? how old is the system?

[CG12]

thanks.

It is pumping over the expansion pipe - full bore !

does this mean the pump has been fitted incorrectly ?

The system is old 10-15 years.
