Thanks for your replies guys. Yes the rooms are occupied, but then so is the kitchen, bathroom. The windows are not closed all the time and the internal doors are open vast majority of time other than at night for privacy.

If you're closing your windows and doors at night you're trapping all the moisture that sleeping humans produce in the room, this is adding to the condensation.

That does make sense. But could you please clarify a few things:-

1. Would running this constantly not cause the boiler to breakdown more quickly?

2. Wouldn't it cost more?

3. Daytime thermostat temp in hallway is 18.5C, which is more than enough as most of the rooms are a lot more warmer (22-23C in most rooms) & better insulated than the hallway, so do i have a different temp at night? ...The reason I ask, is because if it was set at 18.5C day & night, it would be way too hot to sleep.

the boiler keep firing up and shutting down causes just as many problems to the boiler .

yes it would cost more in fuel but you are looking for a cheap cure for your condensation

try the thermostat at 17 and take it from there

@ Teapot - Thanks for the link.

@ peacyprice - Actually I tried leaving windows open a couple of nights and guess what happened? ...The condensation was even worse the next morning.

@ thebaldwindowfitter - I think I've found the correct setting, which is 18C during the day and 16C during the night....let's see how this goes and I'll tweak it, if required.

I just want to let you know that I've ordered a karcher wv2 window vaccuum. At least this should help me in the short term.

How is your condensation

Hello again....A year later!

Really sorry for not being in touch as I've just away for a while.

I've got an update regarding this issue.

Now I don't know if it's due to the weather this winter, but our condensation issue has vastly reduced. The windows still get a very small amount of condensation at the bottom of the glass, but it's only on the odd day and very easily manageable.

Before we'd get condensation even on temperatures being 3-5 degrees outside. This winter the temperatures have been zero or below for almost a week at a time, yet hardly anything at all.

Personally I think the reason is due to us installing a wood burning stove in October. It's been used almost on a daily basis and not only is it heating the house, but it's also reduced the humidity in all our rooms massively.

Correct me if I'm wrong, but the reason I think it's most likely the wood burning stove is because it gives off dry heat, but at the same time, air from the house is being sucked up the chimney via the air vents. In our case it was moist air being pulled.

Average Humidity Levels:
Bedroom: Previously 75-90%. Now 50-60%
Living Room: Previously 70-95%. Now 45-55%

LIVING ROOM:


WOODBURNING STOVE:




Lets just hope that this is what's helped and not just a blip, otherwise I'll be back on this forum once again.

The stove will be pulling in air and expelling air, so the moist air is constantly being replaced by drier air.

You definitely think so?

Let's just hope that it's not all down to the weather and next winter we have a different scenario.

Of course. That's how stoves work. Where do you think the air that goes up the chimney comes from? The house, which is full of relatively moist air from breathing, cooking, bathing, etc. And where do you think the air that replaces that air comes from? The (normally) drier air from outside.

That's great, thanks very much. Now I need to suss out how to resolve the remaining condensation on the windows. It's a couple of inches high from the bottom of the glass.
