Brent Corrigan In A Shower

Well finally the new Canadian

In our environmental concerns and energy saving, we quickly oriented development a Canadian well.

You will probably find a few personal sites but also more and more commercial sites telling you how to buy very expensive something that is very simple at the base.

few succinct reminders: Well
Canada is a heat exchanger consisting of a pipe in which air passes before entering the house.
The pipeline should be at least 1.5 m below ground because at this depth the temperature is almost constant throughout the year (whatever the outside temperature).
The outlet temperature of the sheath can be almost constant year round provided they have a pipeline of sufficient diameter to a sufficient length.
There are 2 main types of system:
- the Canadian well: it provides a warming in winter and cooling in summer
- Well that brings a refreshing Provençal summer.

For more info, I refer you to the excellent work of Samuel Courgey and Jean-Pierre Oliva bioclimatic design published by Living Earth (P171 A178).

home, we have done without too much to bother to calculate speeds, distances ... We made it simple with the constraints of finances, time and terrain.

We bought a double wall corrugated cladding TPC (red!) Of 50 meters and 160 mm in diameter. The sheath has cost us € 295.75 including VAT delivered. We purchased from FRANS BONHOMME (watch list prices are much higher but they are always at least 60% off! Same individuals).
We took the shovel that dug the foundations for him to dig a trench 1.5 m deep at the bottom of which we asked the sheath. We were very careful to not having a break in slope for the moisture of the sheath can not stagnate and thus to prevent the proliferation of any bacteria.

We increased the sheath under the foundation and then we have to show exactly where we wanted it to be good. The hardest thing to imagine a specific location even before the foundation!

We then recapped the trench. The sheath was apparent
therefore "inside" the house throughout the work.

When we realized the various elements that make up our soil - namely the hedgehog, the lime-hemp the floor tiles and mud-we have taken into account instead of the sheath and the importance of the output.

Most designers précaunisent Canadian well to combine this system with an HRV so that air arriving from the Canadian well in winter at a temperature of about 8 to 12 ° C is preheated by the CMV before being driven into the house. Since we do not VMC, there was the problem with this direct arrival of fresh air in the house.
To adjust, we opted for a very personal but it works well (we can say today).

We doubled the wall behind the arrival of Canadian well (this part is lime-hemp) by a wall of adobe (dried mud brick) while leaving an air space between two walls. The output of the pipe system (the sheath) is itself included in a small cabinet also of adobe. This box is isolated from the top (with wool hemp covered with a wooden shelf) so that air can circulate as the air space between the wall of lime-hemp and the wall adobe.

front of the adobe wall is the wood stove that heats the air by radiation and which also heats the wall and the cabinet adobe (ah inertia when you hold us!).

But what becomes of the preheated air as you say? It's an excellent question. We opened the adobe wall and installed a ventilation grille in height. With this "mouth", the air exits temperate.

The first steps that we performed we showed that the air coming out of the sheath into the vessel to a dozen degrees (cons 0 ° outside). At the gate (about 2 meters high, the air was about 20 degrees). It will
achieve more accurate measurements and see if it works also in summer. We do not

motorized air intake for winter as it is warmer in the house and outside, there is a natural aspiration. The question was based differently as it will be cool inside. We will discuss timely ...

Finally, I inform you of the birth of an association whose objective is the promotion of ecology and alternative habitat. This association will be present on some exhibitions and is involved in thinking and implementing an environmental projects. You can contact
at 06 70 66 53 82 or by mail to alpha-bat@laposte.net
Alpha-bat means Logistics Support and Promotion of Housing Alternative.

You will find information about the life of the association through his blog:
