condensation
Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle. It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within the atmosphere. When the transition happens from the gaseous phase into the solid phase directly, the change is called deposition.
Hi
I am having problems in the bathroom with condensation when/after taking a shower which is causing mould.
I believe I need an extra fan to be fitted through the wall with shutter (to prevent cold air coming back in) and run on timer.
1. Should the above be sufficient or is there anything...

So, just curious. Whilst replacing some worrying pipes within the partition wall at the rear of the shower enclosure, I discovered the following...There is a cold water pipe feeding the next door shower.(The showers are back to back) Part of it is a copper pipe into a compression fitting...

Hello all,
Have 3x windows and 2-300mm insulation in attic.
I've noticed recently a wet patch on the ceiling near where the blocked vent is (I know.. I know..).
The vent has been blocked forever but this is only comung up now. There was also some small condensation on the windows this morning...
Hi guys - I have recently noticed that when the hot water is switched on I'm getting a little moisture on the underside of my Ariston Contract STI 150 Indirect Protect (one or two drips on the carpet under the unit after the hot water has been on for 20-25mins). When the hot water is not...
Hi all,
We recently had a ground floor bathroom/wet room finished off, It's about 3.6m long by 2.7m wide, tiled from floor to ceiling and has no window in there due to a future extension that will take place on the other side of the rear wall.
Unfortunately, i've Instantly noticed when...
Hi.
I’ve just changed out a backup immersion heater on a copper vented cylinder.
I’ve leak tested around all the connections to the cylinder using blue paper towel which tends to stain orange with moisture.
After 24-48hrs of use not a trace of moisture.
However after a week or two I’ve...
Hi wondering if anyone could tell me if this is a normal pool of water from condensation coming from pipes. Or does it look more like a leak? Am I best cleaning it all up then trying to identify any small leaks? Thanks
Plumbing/water heater- spots recently on ceiling downstairs, 2 story house. Condensation??? New water heater.
Live in same house now for 20 years but could happen anywhere. Got a new water heater in September on 2nd floor in a tiny closet. In that closet is a metal aluminum vent and also a...
I posted this query on the HVAC reddit but as thats largely a US site I thought I might have better luck here....
My dad has a 1960s semi.
For years he had an old 'behind-the-gas-fire-in the living-room' type boiler, venting up the chimney. With a hot water tank in the loft (attic).
This...
I have a boiler (Potterton Promax 15SL) and after it has been heating the house for a while, when it turns off, warm air gently comes out of the fan unit (which is now off) and the air hits the metal housing of the boiler and condenses, causing it to pool in the bottom of the boiler and...
Hi all,
I've got a British Gas 330+ Heat only boiler and it displayed an F25 error (lack of water iirc) on Sunday. I read the manual and bled the radiators (1 rad had quite a bit of air) and topped the system up a little and sure enough I could then hear water flowing back into the boiler. I...
What are the best pipes and fittings to carry steam from a 2.8kW steam generator to a steam cabin for a short pipe distance of 400mm?
Thinking on the technical, the pipework would have a low internal resistance (smooth inside) and full bore so as not to reduce the steam out. I noticed the...
We have noticed a bad smell when running hot water and think it might be linked to the boiler condensation pipe (the water itself doesn't smell)
We noticed that the top of the condensation pipe isn't sealed properly but I have also been told that this is normal (picture attached)
So far I have...
Bit of an odd one...

Toilet room has no radiator or vent and is generally quite cold. But the water in the cistern is much colder and the cistern is covered in condensation. It...
Hi Guys just after a bit of advice..
I own a mid terrace house that has a shared gutter down pipe. The pipe is approximately 45cm inside the border of my property.
Would anyone know if my neighbour is allowed to have his condensation pipe running into this gutter🤔🤔
Many thanks 👍
Just left a job literally, tenant contacted landlord with smell of gas. Tightness okay, gas sniffer didn’t pick up anything either. I got out the analyser and 50ppm in airing cupboard, tenant had rammed a ton of junk in the cupboard and dislodged the condensate pipe. The trap was bone dry....she...
I live in a shared ownership property and had no issues in a “protected” period of a year for defects. It is 18th month of my living here. I was away on holidays and now found out this on my return (in a hallway next to storage area). Do you think it is a leak? Or just condensation? What can I...
