Drilled hole for Mechanical Ventilator with Heat Recovery (blog post)
Today I drilled the hole for our mechanical ventilation with heat recovery unit. Quite a scary drill but it went without any serious problems. My biggest fear was that the drill would "kick" really hard if it suddenly jammed but the drill had an automatic clutch so it would disengage whenever the drill got stuck. It still kicks a bit, but not too hard.

Our Mechanical Ventilation with Heat Recovery unit has arrived (blog post)
I'm in the middle of renovating our living room:
We're insulating the external walls and floor and making it as airtight as possible. Airtight construction is good for minimising heat losses but not so good for breathing. So we bought a mechanical ventilation with heat recovery unit which pulls warm, stale air out of the room and sucks in fresh air. It transfers 85% of the heat from the warm exhaust air to the incoming fresh air. So you get fresh air without wasting too much heat.
If you're interested, I've written up my MVHR research on EnviroWiki: envirowiki.org.uk/wiki/Mechanical_Ventilation_with_Heat_Recovery
The unit has just arrived. I'll install it over the next few days.
