Condensation on Cast Iron Cistern

[MasterPlumbersKeymaster]

Anyone know how to stop the condensation forming on a cast iron cistern?

[Harold KestenholzParticipant]

Condensation forms upon a surface because the surface temperature is below the dew-point of the moisture in the surrounding air.
You can:

Reduce the amount of moisture in the surrounding air with a dehumidifier.

Raise the temperature of the contents of the cistern.

Insulate with a sealed foam insulation to have a higher temperature cistern surface.

Thanks for the advice. The 3rd option seems best for us. Do you have a brand name for the sealed foam insulation, or any advice on where to buy it?
