Hi everyone,
I hope this isn't too boring a topic, but I am genuinely interested....
This weekend we went to visit 2 different friends at their homes. Both times they had several windows open and said they were airing the house (I didn't enquire, they just mentioned it for some reason)
At this time of year we rarely open the windows in our house because of the temperature?
Should I still be doing this? If so when and how often? I am at work all day and in the evening and morning I don't want to let all the warm air out that I've just paid to heat up for 2 hours?!?
Thanks.
