PAC air / water and Canadian well

[gespoi]

Hello, I would like to know if in your opinion it is possible to couple a heat pump air water to a well of Provence to overcome low winter temperatures and take the outside air at a constant temperature? Well on the well of Provence will be buried deeply.
What do you think? idea or debility?

[Philippe Schutt]

I will say that it is not adapted to the air flow of a PAC. unless you have a cave under the house

[gespoi]

Do you mean that the flow of a heat pump is too important for the heat exchange between the earth and the air to be good?
To overcome this, can we increase the length of the pipe (100m .... maybe) to capture a maximum of calories?

[gespoi]

Uh, after reflection, it is better perhaps to put several parallel?

[Philippe Schutt]

it is necessary to limit the losses of load, thus to preserve a section higher than that of the exchanger.
then, the air in contact with the walls will heat, but not the one in the center of the pipe. so you have to make a few elbows, so that the air gets brewed. or a lot of smaller pipes.
won't a "geothermal" water / water cap be less expensive in the end ??

It's not stupid at all, the proof is that others have thought before you. Take a look at this site of an Alsatian who has built bio: you will find a lot of very specific info on the Canadian well and there is a forum also :

[Philippe Schutt]

yes, and it is very explicit regarding airflows.

There are also water-air systems that are efficient (ned air)

I will modify my article by adding this technique

section: Canadian well

[Olivier31]

Just a note on brine wells (water-air system).
They have a higher yield than the standard Canadian well in the winter, but much lower in terms of refreshing the habitat in the summer.

To choose in beosin for the cold regions or the Canadian well will be used mainly to warm the air.

In many areas with all the wood thrown around, I would take the green heat and hard wood and not the heat pump that pushes to build new EPR nuclear power plants that may make us a Chernobyl in France sooner or later because the nuclear can not be infallible in perpetuity !!!
Ecolo as much as possible, it's not a heat pump even with a Canadian well.
To choose or to favor nuclear electricity whereas one has the choice, it is to approach a Chernobyl in France !!!

Some nice boilers that burn everything !!

One day, an unthinkable nuclear accident will occur in France and it will evacuate an entire region in one night to avoid coming back for centuries, even millennia!
We have come close to such accidents already !!!

Read these staggering reports if you want to have a Chernobyl in France !!!

To read this report too:

The greenest possible is not the lie of the electric heat pump of nuclear origin !!!
But the wood heating recovering all the plants discarded and neglected at present or wind or solar.
In Périgord full of wood, the heat pump is perfectly useless !!!
