Paint the cistern with emusion paint  

Or, don't have showers.

Is the cistern filled from the mains or from the loft storage tank?  Condensation is more likely if it's mains fed as the water coming into the cistern (at this time of year) is colder than the water sat in the storage tank in the loft.

This is 'cos the loft is slightly warmer than outside and the tank water has time to rise in temperature before entering the wc cistern.

Lot to be said for back-to-wall cisterns!  

You are just being silly now Wolf  

That would mean there is condensation inside as well as outside  :-D

Leaving out the water wouldn't stop it anyway.

Its the cold glossy surface that causes the problem, the same as tiles and gloss paint.

Also check the condensation levels using a bath against a shower.

YEP!   i sure was !!!

and even sillier now i've been waist deep in a  F-kin freezing river removing a fallen tree from power lines for the last few hours!

BBBBRRRR!!!!!!!!!!!!

Nearly but not quite, .....

OKAY! so i bagged some of the timber, and will probably get more of it to!

but one of the "ESTATES" (country that is!) i help look after had a tree come down in the storms on Thursday,and it took out the 3 phase lines to the "ona pole" sub box!!  and good old EDF energy was a bit late in getting to the problem...   like thursday, tikk SUNDAY! shame on you guys!!!!

the trouble is/was , they turned up with a 3 man  crew  but without any chain saws! ..and seeing as Wolf never leaves home with out one!! , i was asked to help them out by the estate owner!

no here is where there small problem really lay, the Poplar tree was on one side of the River, it fell ACROSS the river at about 75° taking out the cables as they cross the river to the sub box!! trapping one with it!

so poor wolfie, ended up wading into it, ( wellingtons were a waste of effort!) just shy of waist deep, and removed from said tree,the two main trunks , releasing the cable!!

i made the 3 from edf help me remove the trunks prior to them starting on the cable of course,..quick change of lower clothes, and ooops! i set about sawing up the trunks!!!

and just spent the last 3 hours sizing it, and wax coating the ends so i can turn it on the lathe a few months from now..( maybe about 12-14 months time!!!! )

Is heating the water such a daft idea?. You would probably only need to heat it a degree or two above room temperature. That wouldn't take much energy.... after all the room will warm up the water anyway and that energy is supplied by the central heating. Obviously the energy is lost when the loo is flushed so perhaps a grey water heat exchanger would be a good idea as well.

The problem is how to heat the water. How about arranging for the hot water you use to wash your hands to refill the loo? Quick patent the idea someone.  

I would replumb it from the loft storage tank (assuming you have one).  If this is too much grief then there's little else that can be done easily.  A btw cistern helps but again, that's a lot of work to change.

If it's mains fed then I assume you're getting condenstion on the copper supply pipe (to the wc cistern) too?  Is the wc overflow copper, that'll be even colder (as it pokes through the wall), if so change it to plastic.
