Dehumidifier question.

[Alcazar]

After advice from a couple who also have a holiday home in the same area as us, but who have had theirs for a lot longer, we've invested in a Wickes dehumidifier.

It has humidity settings from 95% down to 10% or less.

What's normal for inside a property? What should we set it on, so as NOT to upset an old property, or our health. I'm sure I've read somewhere that too dry = sinus problems?

Thanks,

Below 60% should restrict mould growth and below 50% should restrict dust mites. Below 30% is too dry and bad for the health.

We have a weather station that gives a relative humidity figure for the house and we try to keep it at about 50%. When the poele à pétrole is on the humidity tends to rise as you might expect but when the log fire is burning the humidity tends to drop to about 46% again as you might expect.

When we first moved in the house had been empty for several months and the air was saturated, damp cellar and walls etc, and so we bought a Zibro Clima dehumidifier which removed many litres for several days to get it back to normal.

Electric heating and log fires would tend to lower relative humidity as warm air can support more water vapour and a log fire will suck in fresh air from outside. Parafin heaters produce a lot of water and so push the relative humidity up.

Hope that this is of some help..................................John not Jackie

Thanks for that, I'll set ours on 55% and see what it does.
