History - end of terrace old (pre 1850) house, adjoining wall is cob and the rest (as the cob fell down 20 years ago!) has been rebuilt so only 20 years old. Floor I think is just built on the ground as under the stair whilst working on the understairs cupboard I just dug down into the soil, I think floor is just concrete onto ground.

Seven (out of 8) windows in total are single glazed sash windows. Loft has insulation but is only 100mm thick and when I can will upgrade to 300mm.

House is cold normally and loses heat fast, ie OK when central heating is on but within 10mins of CH turning off you can feel it, no doubt partly due to loft insulation.

No mould visible in any of the rooms but there is a little dry rot on 2 areas of skirting.

Relative humidity was 70% + in all rooms and mornings the windows could be found running with water, even if left open overnight.

On a normal Autumn/Winter/Spring morning there was much condensation ranging from 150ml of water per window to 250ml per window - had to get a Karcher window vac to suck it up - the paint did not like the water and began to peel/come away from the glass.


Install:
Annoyingly the previous owners just boarded over the ceiling so I found I had original plaster and lathe ceiling and then 2 inches below new plasterboard - luckily though I found the old loft hatch to situate the Drimaster.

I opted for the Drimaster Eco Hall - no heater and can adjust the settings at the vent in the hallway rather than in the loft.

I also wired mine up so I can turn off the power via a plug downstairs (I Emailed Nuaire prior to this to see if this was feasible) via a 1amp fuse.

In the hallway below I can adjust fan rate etc...

I used a junction box to join my feed from socket to the power adaptor on the Drimaster - the manual states to run it from the lighting ring via a 1 amp fused spur, (needing an electrician to install plus the associate costs involved) thus my Email to Nuaire asking why not just use a 1 amp fused plug to socket saving an electricians bill, time off work to let electrician and ease of having the option to turn it off if required in etc. etc......


So first day after install (Monday 22 Oct) there was about 1 inch of condensation on 1 bedroom window and the other bedroom window had 70% condensation which I was a little miffed about. Second day showed no condensation on one window and about an inch on the other. This morning showed none on either.

No sure on the weather if we would have had condensation anyway without the Drimaster today but so far it seems to be getting better and better.

Relative humidity has gone down to on average 65% so a bit disappointed about that but am hoping it will drop further.

The landing does seem a little cooler but the rest of the house does not seem to be affected by the coolness, it is very quiet - ours is currently on level 3 (out of 6) and can hardly hear it standing underneath it.

Here is a awesome paint drawing of its location - i could not get it directly above the stairwell due to access, sloping roof, etc....

I'm going to see how it goes as the weather gets colder/central heating kicks in etc......
