We’ve now been living in this house for 3 years and one of the greatest pleasures is walking into the house in winter and instantly feeling the warmth of the house – regardless of whether the wood stove is on or not.
The insulation we installed in the walls, roof and floor of this house, together with the triple glazing, are working beyond our expectations to keep the house warm in winter and cool in summer. While the house isn’t an airtight passive house (or Passivhaus), which generally employ heat exchanging air vent systems, we designed it to perform as close as possible to a true passive house.
In winter, and without any heating, the house only very rarely gets below 15°C, regardless of the temperatures outside. Today (23rd Jan 2017) is a good example. Outside is 0°C and snowing hard. The wood stove was on the previous night only until 11.00pm and without any heating since then, at midday the house temperature is still hovering around 16°C.
1st year data on the inside and outside temperatures – see Insulation – 1st year’s performance – to give a better picture of how the inside temperature changes are minimized by the effects of the insulation.
And further details of the insulation we used can be found at this other earlier blog entry; Insulation.
