Newbie post , so I apologise for any blatantly obvious questions in advance, (I have had a look around for answers to no avail)...
As mentioned elsewhere I have just purged the footing on our project in Devon, and the scope creep has started...
At present had planned on conventional extractor fans, in Kitchen, bathroom and ensuite, this has progressed to should I have a centralised system, which in turn could become a full mhrv system.
Now if this was to be my main home, I would jump at Mhrv, however I'm initially only going to be using the house for occasional weekends and holidays, before the haters come out, the family has been linked with the village for 4 generations, and one day in the distant future I might retire....
The thought of an Mhrv system whirring away in an empty house does not seem right to me. Also I'm trying to do this on a budget, with a view to enhancing in the future, but conscious that it makes more sense to put ducting in now, even if it is not connected up!
I'm looking to get a decent degree of air tightness, it is a timber frame and cedar clad construction. Detail below
The layout, will be primarily glazed to the South West Aspect, with a 2m roof overhang to provide solar shading, however I'm conscious that it is likely to get warm in Summer, so if I had an extract vent at the in the main front room, at the opposite side to the kitchen, would this help to extract hot air from the house? (Summer bypass?)
The front aspect will have 3 glazed sliding doors totalling 7m wide 2.4m tall, which will be open as much as the uk climate permits, kind of negates passive haus...
Also there will be a log burner in the front room, is this going to complicate the whole mhrv deal?
Thoughts and comments welcomed!
