Air tightness questions (newbie!)

[gc100]

Hi all,

 

I want our house to have a good air tightness so that we can heat the whole house with via air source or ground source (180m2). I have no idea of the terms or scale or what values I should be going for. Are their any articles or FAQs that go through all the basics so I can understand ?

 

Many thanks

Air tightness is a major factor in the overall performance of the house, and it's the performance that dictates your heating requirements. To work out your heating requirement you need to create an energy model, of which air permeability is an important element.

 

So the answer to your question of what values you should be looking for is... it depends.
