Me too. When I was there the results were better.

I don't know if "what number are you looking  for" is an honest attempt at helping, but at least he knew a target and could report on the spot and look for an issue.

Well done on getting it through the check.

 

I would be inclined to side with @JohnMo on this one and chuck in a dMEV or two anyway. I wouldn't bother with the undercuts for now.

 

At the very least spend £5 on a cheap humidistat to keep an eye on the humidity. Its you who will benefit from the better indoor air quality and lack of noise anyway.

As luck would have it, there is a humidity sensor on each of my thermostat/heating controllers so I can monitor it that way. Is there a dangerous level of humidity that it's advisable to stay below?

Just as an aside it is interesting how many posts we have seen on this topic, it must have hit the zeitgeist right on the head!

The dew point is one.

Td = T - ((100 - RH)/5)

Where T is ⁰C, RH in % and above 50.
