New multi fuel burner

[muggles]

OK, just asking because modern houses require more ventilation than older ones. Either way though, the stated ventilation requirement is a minimum, all sorts of things can affect the actual requirement and it could be significantly more than the minimum. As has been suggested, try opening a window a small amount and seeing if the problem goes away

All these answers are for condensation on the inside of window which i take it you mean and not on the outside of the window? which with the new high efficiency glass is normal

Here's a theory.... since it is an old house, the area round the fireplace may have had a little damp in it.. Now you have a stove burning in that area and it is warming the masonry and causing the damp to evaporate and condense on the windows... Similarly if during the process of fitting the stove you have had any plaster work done which will give off its water untill it is fully dry.... All assuming that the condensation occours over night once the stove has gone out..

Oooh now there's an interesting point Grouch, not many people would have thought of that!!

I would imagine it would be first thing if you where standing looking at it

If I instal them and leave them open all the time then surely that will increase my permanent ventilation thought?

Yes, obviously it will. But that may not be your problem. So, open a window to replicate a permanent vent. If all is ok, but problem returns when closed, then you know a vent likely to cure
