Most efficient heating / airing pattern

Yoite

Hello,

I have just moved into a new house which is not well insulated as of yet, so we have some condensation on the windows during the night. I am trying to find the most efficient pattern in order to keep the house warm AND well ventilated during the winter. Any advice on when to turn on the heating and when to open windows?

Thanks,
Julia

Sorry I can't really help, but really interested to hear people's views on this.

I'm in the same position, and seem to heat up my flat, just to have to open the windows and lose all the heat.

Even with double glazing and a well insulated house, you will get condensation on the bedroom windows; many people do not realize how much vapour is produced by people at night.


You can remove the condensation quickly with a squeegee and a cloth, or something like a Karcher window vac.

We have the same problem as you but whereas the condensation was streaming down most of the windows yesterday they were all clear this morning!

One bedroom is particularly bad at times and we have noticed signs of damp on the walls near the windows, we are almost certain there is no leak coming in from outside.

We are looking into the best ways of ventilating the worst rooms and have just decided to buy a dehumidifier.

It depends on how much money you want to spend. The most "efficient" (if I understand your use of that word to mean how do I use as little energy as possible to heat and ventilate) way is to air tighten the house and use a ventilation system with a heat exchanger. Google "MVHR". But you're talking LOTS of money and disruption.
