major cistern condensation issues

consumers_revenge

Hi,

Admins feel free to delete this question if it breaks any rules please. If I contact anyone via PM please feel free to report me as Im not selling anything.
So Im a person who gets a soaking toilet cistern every time we have showers or bath and it streams down. Having looked online for several hours the best Ive seen is fill the inside with foam, stick on yoga mats, fed hot water, outside cover etc but all of these except the cover (very tasteful) eventually break up.

So I asking a sensible question here as I think I've come up with a  genuine way to stop this and I want to see if people would consider changing their toilet to get rid of the problem. The price should be about the same as any other toilet, though thats just assumption and its a permanent solution. Im replacing my loo at the moment as part of a bathroom refit and would get one if it currently existed.

So Im doing a poll to see if its worth moving onto the next stage of patent/design etc which I currently know little about. No one seems to be doing what I think  is needed.

a)water dripping doesnt worry me or we dont get the issue
b)yes its dripping but I wouldnt buy a new toilet
c)yes I would replace my current loo (or when I have a bathroom refresh)

Thanks

d) Don't suffer from any noticeable condensation on the cistern.

OK amended options as we never get any condensation in downstairs lav :-)

part of the reason for asking this. If it doesnt affect as many as Ive seen on forums then I wont pursue this idea

@consumers_revenge     Does your bathroom have a extractor fan ?   Or simply open a window.

Extractor fan as part of refurb soon and I have trickle vents in window already.
But I know of many who have a fan and still get issues.
This just relates to removing/preventing the condensation on the cistern which seems to be the major issue I've found on  google and builders forums etc.
Im no inventor but this seemed so simple (I cant find anything close) and maybe someone has come across it but I certainly havent found it mentioned anywhere and an engineering friend said yep that would work?

There's sometimes a bit of condensation on ours, but it doesn't bother us.

As above - there's always a small amount forming, especially in cold weather - you can even 'see' the fill level inside! But, if it becomes an issue large enough to cause drips onto the floor, it means you aren't ventilating away the moisture enough - that's it.

It ain't the cistern wot's at fault. And if folk don't keep their bathroom ventilated enough, they sure ain't going to invest in an insulated cistern.

Jeepers, it's a bit more complex than that!   

In winter, with central heating running and a house at 20C and 40% RH, a dew point is reached at about  6C, while the incoming water temperature can be as low as 3C or 4C (at least where we live!).  If you flush the toilet, then have a shower - even with a good extractor fan and room air-replacement rate, the RH is bound to rise temporarily, taking the RH up to possibly 70% and leading to a dew point that would be 15C.

While normally this is no problem and the cistern water temperature manages to rise to room temperature, there will be occasions when the toilet is used several times in short succession (as is quite often the case in a house with only one toilet) and it will easily create enough condensation to drip onto the floor.  

EDIT:  But would I pay for a fancy cistern solution?  Probably not!

I don't think this is a marketable product.  

Over 20 years I've been doing this now and enough condensation on a cistern to cause a genuine issue has never been a conversation.   Condensation on the cistern has never been a conversation either.  

"Fabric First" - the primary aims in any house should be insulation to the room (not the toilet), some decent heat and an extractors in relevant rooms that sense humidity and work until levels have stabilised.  Once you're beyond that, I don't think there could be cause for any major issue - You need to be improving the house, not the loo, because the problems with condensation are further reaching and more problematic than  just a soggy cistern.    Mould, for a start and/or an uncomfortably cold room.

have heating/had fan.
OK prob wrong forum to aim this at judging by responses.
Cheers.
