toilet cycstern condensation?? help

[suzanneb]

we had a new bathroom suite in about 1 yr ago, recently the cycstern front seem to collect water and then drips all over the floor. its not coming out of the cycstern lid its condensation collecting on the outer cover, even when no one has had a bath, it does it. we have a fan which takes the steam out the room which works when the light switched on, we also have a small radiator which is only on low. im forever mopping up puddles of water at the side of the toilet. ive tried washing the unit and drying it but within a few hours it back......it driving me nuts!! help...

I'm assuming the equivalent term here in the U.S. to your cistern is what we call the tank. It holds the water until flushed, right? If so, a simple fix is to flush the toilet after shutting off it's the water supply. When the tank or cistern is nearly empty use 1/2 inch rigid styrofoam insulation (the kind that looks like zillions of little beads stuck together) that you purchased at your DIY store and, cutting it to fit with scissors, place in the tank around all of the sides. If you do it carefully, you won't have to glue it. If you do, just alitle glue of any kind will work. This will insulate the tank and the dripping water will cease... Best of luck! (Turn the water supply back on, by the way...)

Traditionally, to cure this, the cistern would be boxed in, with insulation between the tank and the box, using sheep's wool, or, these days, fibreglass loft insulation.
Clanad's suggestion is the more modern way, and there's an alternative to styrofoam (expanded polystyrene) shown here
If you end up glueing, do ensure the inside is totally dry first.
