in vertical geothermal energy (around € 25000) including the heat pump
This part of the sentence contains dramatic contradictions typical of our deceptive society !!
The term geothermal energy is bogus, a misleading term, a real scam, because it is not the heat of the earth but in reality solar heat stored spontaneously, underground for years, average between summer and winter, by thermal contact between atmosphere and earth !!
Then a heat pump, needs electricity which pushes towards nuclear power, absurd, if we do not want a Chernobyl-Fukushima in France, sooner or later it will be certain, given that nuclear power and people cannot be infallible in perpetuity. !!
In addition, Canadian wells are often small, because an input heat pump needs an amount of heat equal to the thermal consumption of the house over the winter and therefore cools the earth a lot to provide that heat.
It is necessary to do the calculation, but, in order not to cool this earth too much to 12 ° C, with 0 ° C and less outside for months, the volume of earth necessary is between 1000 and 2000m3 for a well-insulated house and 4 times more if Ancient !!
So check the calculation of the volume of soil taken, but it must be greater than that for storing summer solar heat in the same well, because, then, the temperature amplitude, between 20 ° C and 60 ° C and more with solar collectors, is in this case much greater than for a few degrees below 12 ° C !! To have only 4 ° C of cooling from the Canadian well, it takes 10 times more earth, than to heat 40 ° C, with the same amount of heat available !!
So there is another scam with the undersized Canadian well without saying it, because otherwise too expensive to dig !!
In addition, the well must be more than 3m deep, minimum distance of diffusion of the cold over 4 months !! (with some rock soils, it is 6m)
To calculate, take the heat capacity of the earth multiplied by the allowable temperature difference, (4 ° C from 12 ° C to 8 ° C) and calculate the volume of earth necessary to provide the heat necessary for heating with the heat pump!
So certainty of repeated scams, with as soon as it is cold a week, after the well, the air inlet temperature of the heat pump barely higher than that of the outside !!!!
Without speaking about those who paid 30000 € for a CAP that only worked for 3 days, time to pay for a bankrupt company, without ever seeing their lost € 30000 again, with an irreparable, badly mounted CAP !!!
Case of friends of the parents of one of my beautiful daughters !!
Not to mention the PAC which has become obsolete in less than a few years, standards (my personal case), without repair parts because the manufacturer has disappeared, bought back, etc ... to be completely bought (my personal case).
Instead of the heat pump, it is better to have summer sensors storing the heat wasted in the summer in the well to heat the winter as carried out in www.dlsc.ca

Only considering that, after consuming more of anything, no one offers it, this solution that saves the planet without CO2 !!
In the short term, like for me, the cheapest is to burn free wood and free plants abandoned everywhere as I see around my home, 900Km away, in an insert, stove or mixed boiler with wood, pellets !!!
In addition to doing the exercise of collecting and sawing by hand this wood lost at home and its neighbors which smoke you for days to burn it in the open air, is excellent for health, since we do not exercise enough. physical, given the obesity epidemic.
Finally, I hope I didn't get tired of writing this text for plums !!
