geek4me: We are in a newly built Golden Home for 2 years now. It has double glazing, a heat pump but no HRV system. We have had condensation issues both winters.

The main problem is the double glazing was done (cheaply) without an insulation layer between the outside and the inside metal frames. The cold outside temperature transfers directly to the inside metal causing bad condensation on the metal and inside glass requiring the windows to be wiped dry each winter morning.

Keeping bedroom doors open at night reduced the problem, if closed water would condense and drip from bedroom light fittings.


An HRV would definitely help reduce this condensation as would (more expensive) insulated double glazing in my opinion. Sub standard bathroom heat-light-fan extractor units which do not extract the required volume of damp bathroom air do not help the situation.


 

Thats why it is important to spend the money initially on a well designed house with passive solar heating and natural ventiallation, and  with high quality componentry. What you would need is thermally insulated aluminum profiles, as you get condensation on the cold aluminum window frames, and that is a common issue. The alternative is to use timber or PVC frames. The aluminium frames should have a drip tray at the bottom, with a drain to the outside, to drain out the condensation.

Consumer mentioned double glazed aluminium windows in the current or previous issue, how they need an insulating layer in there.

I had my old wooden windows retrofitted with double glazing by Magnetite in Wellington. They have a good product but shockingly bad service, and incompetent installers who did very shoddy work for me. They had to come back five times to do significant rework, they basically put the windows up three times before they got it right. One panel and mounting system actually fell right off the window onto the ground, and the rest were on the way. They also did $3500 worth of damage to my carpet and curtains, getting silicone sealant onto them.

Our house has a heatpump and HRV system with the outside vent add on.
Problem is the HRV will always circulate air constantly. So you have to turn it off to stop it bringing cold air down from the attic or outside when you are trying to heat with the heatpump. And on a cold night you have to turn it off, but it starts up after 8 hours again so on a cold morning, its freezing inside the house.

Also a heatpump will only dry the air when it is cooling the air. Some heatpumps have a dehumidify mode where they will Heat, then cool, then heat - maintaining the temperature but drying during the cooling stages.

Heat pumps have timers, in the winter I always set it to come on an hour before I get out of bed.
