My house is just over 1 year old and throughout the colder months we get bad condensation on the inside of the windows. We have the gas ducted heating on 16 overnight. I'm not sure what I'm doing wrong !
Please help any ideas?

Re: Condensation 2Jul 13, 2019 2:11 pm It's not so much temperature but moisture levels inside your house. Unfortunately when very cold outside the window glass will be below the dew point (temperature below which condensation forms for a given moisture content in the inside air). This also happens in the tropics at warmer temperatures where the air is very moist. Does your air conditioner have a dehumidifier mode, if so use that. Make sure you use exhaust fans in the kitchen (or range hood), bathrooms and laundry. Nag the kids to use the fan when showering. The clothes dryer in the laundry produces a lot of moisture unless it is a condensing type or is ducted to outside. Make sure an exhaust fan is on and window open. If all of that doesn't help you can buy portable dehumidifiers. I assume you also don't have double glazed windows because they help a lot. I should also add that gas heating produces water as a combustion product. An indirect system (where the flame is completely separated from the circulating air) doesn't have that problem. Re: Condensation 3Sep 25, 2019 1:09 pm Have you looked into decentalised ventilation with heat recovery? Could be a good way to keep condensation down. Heat recovery will avoid any heat loss during winter. Decentralised units are easy to retrofit and not too expensive. Re: Condensation 4Apr 20, 2020 10:28 pm Hi, we moved into a brand new townhouse 8 months ago, our windows are double glazes, so here we was thinking that what everyone had told us about double glaze windows stopping condensation, it was all a load of rubbish, and we are in the process of tinting all our windows with SolarGuard brand Silver 20 tint to stop sun glare and heat when the sun is shining thru our windows, as well as for privacy, and we will be fitting fabric Roman blinds to replace the horrible roller blinds that the builder put on all the windows. Our SolarGuard national rep has told us the same, that double glazed windows will not stop condensation completely if your home curently suffers from this, however in some cases it CAN help prevent it to some degree, he explained why it does not prevent it completely, but it is too complex to explain here. Condensation is the curse of all home owners who suffer from this big problem, and no matter who you talk to, you will be advised differently by all of them on how to fix it, and i have spent the past 2 weeks full time trying to understand what causes it, and how to stop it in our own home, others may find the causes and prevention may be slightly different in their homes, but the solution to me always seems to come back to reducing moisture in the home, and then creating a good flow of air around the inside of the home. We always believed that having curtains clossed over the windows while the heaters were on would stop the condensation from happening, because the curtain would prevent the air behind the curtain from heating up, but not so, warmth still gets past the curtain to make the air behind them slightly warmer than the air outside the glass, and even if the temperature of the air on the inside of the glass is just a few degrees higher that the air outside, condensation will still occur, and in our previous home for 21 years we suffered with condensation over all our glass behind curtains, and it was a nightmare, had to wipe them down every day, and wipe the aluminium frame and window sill as well. We are going to borrow a humidifier for a week to put in our daughters bedroom (the worse room) and see if those work first, then if it fails, we will look an the next option, as yet not determined. It will be a case of patience and testing by trial and error, so if i can work our our condensation i will post back in here to let you know how we went. Cheers |
