Dedeleco -> the part with crawl space has in fact been accessible and better ventilated for about 1 month. I did more ventilation to avoid having too much humidity.
It is indeed isolable from below.

Regarding the insulation of the wooden frame part "placed" on the concrete slab, I don't really see how to do it from the outside, without blocking the ventilation from below which is important to me.

Here are 2 more precise photos of the wood part on a slab:

The cellular concrete junction (thicker on the right) with the wood frame part seen from the inside:

For me the corner is a small thermal bridge all the same

Regarding the heating note, between April 2009 and end of December 2010 we paid 800 € electricity (all inclusive), so for 9 months.

Since the beginning of January until now, we burned 700kg pellets. But the significant improvement in insulation is less than 15 days. So that makes us 700kg / 15 = 47 bags to 3,90 or 183 € heating for 2 cold months.

impressions

The parquet is on joists apparently and so it is possible to isolate between the slab (thick enough to be waterproof in my opinion) and the floor between each joist, if my impression on the photo is accurate?
The second photo is less clear because you indicate that the photo is from inside while you have a portion without floor with soil inside?
The crawl space is not clear or visible.
Finally a thermal bridge is difficult to see on a photo except thick black mold due to condensation (sometimes also due to wet leakage). The corner seems more a plaster connection visible under the paint ???
The test is the thermometer colder or with humid air, the condensation water flowing on the cold part (the test on waterproof plastic film allows to separate condensation of wall of the external humidity).
Your heating rating of 1200 € max a year does not seem catastrophic for a not too big but unknown area of ​​your house?
I do not know about you, but for me if the taxes (land and housing) are more than 3times heating, the motivation to win on heating is low, I would rather want to vote differently.

About the infrared thermometers and without contact, I don't understand pkoi you are looking "far" for what is under your eyes (or almost): Measuring and Diagnostic Devices Energy, Electricity and Environment

Dedeleco -> The 2 1st photos are from the outside.

In fact what I show in the photos is the part with ventilation below the floor not accessible.

here is a plan to better understand:

http://nsa13.casimages.com/img/2010/03/ ... 628809.jpg

The accessible part with crawl space is the other part of the house.

Regarding the interior area it is about 80² and we have less tax than heating ...

The 3eme photo where we see the evacuation of smoke is the one inside

Regarding the hypothetical thermal bridge, I find that the corner formed by the connection is cold.

Christophe -> For thermometers, which one is best in your opinion? are the 20 € additional of the 2nd really justified

The ranges of use and products are not the same ... there is no justification to look for a price but a fair price / just use ...

In your case, to make household energy diagnosis so "low T °" the 2nd is enough ... especially since it can measure solid / liquid and pipes as well.

IR measuring range: -35 ° C to 260 ° C

it is true that the second model is better adapted
personally I owned the medical model and I used it -after comparison with an ordinary thermometer-
I did not go buy another model for 30 measures
