Minimum Heat Levels Posted by: MartinW 24 Jun 2010 4:00pm

"Heat lounges to at least 18°C, bedrooms to 16°C"

All the time, or just when the rooms are in use?

What is the ideal humidity? Posted by: Darren Hocken 28 Jun 2009 9:40am

Does any one know what the indoor humidity in terms of percentage should be? There are lots of articles being written in NZ about dehumidifying houses but non actual specify what the target should be.

In your report you state "It's not the cold and damp that harms us." That's by no means true. Cold and damp do harm us, just as much as mould and dust mites. Human physiological responses to cold (i.e temperatures below those recommended by the WHO) include reduced immunity, higher blood pressure, and respiratory inflammation. These responses increase the likelihood of both respiratory illness, and circulatory illness (heart attack, stroke etc.). The phrase you use should be ""It's not JUST the cold and damp that harms us."

We noticed a big difference after we installed a decent bathroom extractor and put a delayed timer on it. It runs for 7 minutes after we turn the switch off. No wet mirrors and a drier house.
