De-humidifier question

The traditional way to deal with condensation is to open the windows a tiny bit. It works really well and costs nothing - heat loss is probably less than cost of running a de-humidifier. It also refreshes the air and is good for you. But you will always have some condensation with ali windows due to cool surfaces. Wiping off with a sponge would be more sensible than running a de-humidifier indefinitely. Nobody had ever heard of de-humidifiers until double glazing with draught proof seals became the norm along with condensation, stuffy rooms, sick building syndrome, respiratory problems, mould growth etc. cheers

I dont think it is, no.

up to a point, yup

I thought they were very similar to upvc windows, filled with foam, meaning they should insulate fairly well. Not sure though.

Continuing condensation is a recipe for toxic mould, the problem needs fixing.

all these were known before dg became the norm.
re free trials, you'll only end up paying more if you go with those. Dehumids are 150 in shops, always get one with a humidistat. Why would you need to trial one anyway? You know what it does.

This was a post a while back where I was trying to get rid of damp in an underground room - effectively a cellar but on same level as the rest of the house. Opening the window wasn't the solution - in fact NT pointed out how it could make it worse - but another poster suggested a new type of dehunidifier which is currently removing about 5 litres of water per day. Hopefully this will drop off in a few days though.

Let us know what happens on that project.

I doubt it :( there's more where that came from....
Running the dehumidifier for an hour several times a day might be much more cost effective, a cheap 'hygrometer' would tell how long it takes for the damp to be removed and return.
If it's not helping enough some form of damp proof dry lining with the cavity vented to outside might help.
cheers, Pete.
