I respond to Obamot who never stops denigrating and seeing there lies, that the
gas power plant

There is no gas plant, only a gas backup for the solar domestic hot water DHW in each house, decoupled from the heating of the house.
They were very careful to separate the DHW functions from the heating of the buildings, for total success, and to avoid mistakes by trying to do everything at once.
The heating of the houses is 100% solar summer stored in earth to heat the winter.

The pros love what brings in lots of money and therefore why keep it simple when it can be complicated and very expensive, in the expensive Swiss solution to obamot, impossible in France on our 99% of our old houses, especially if no one realizes of this simple possibility, like obamot, and obamot in stubborn denigrating, arcbouté, prevents awareness of this simple solution.
www.dlsc.ca awarded worldwide.

It is biblically simple:
the same very inexpensive 16mm pipe (for drip 10 to 20 € per 100m) heats up in the sun in summer (sensor without rudimentary pretension) to pass in the earth this heat (Canadian preheated well as simple) and recovers this heat in winter to heat the house !!!


If the Romans had had this miraculous black pipe, they would have done that 2000 years ago and we would have been heating for free for 2000 years !!
We do not realize the fantastic progress of simple plastic pipes, because without pipes (only in hyper-expensive lead and poison), the Romans only had aqueducts, even Louis 14 !!

Without this awareness of this possible, efficient, functional renewable, the French continue in nuclear power, and obamot pushes the French to continue nuclear, and therefore it favors the arrival of a radioactive cloud over Switzerland, coming from France, following a Fukushima-Chernobyl disaster in France, sooner or later, given the impossibility of humans to be infallible in perpetuity !!

What about 10 years later with the Drake Landing Solar Community project?

Maintenance ? Real costs? User satisfaction?

It's as beautiful as Johnny:

I was serious Guy!

It would be nice to know what it is 10 years later!

This solution was so dear to our dedeleco!

A success
Project progress
After nearly 14 years of continuous monitoring, performance analysis and improvements, a significant body of knowledge and experience has been acquired on the BTES solar system for Canadian applications. NRCan is currently considering expanding the research focus to other areas of applied low-carbon community energy systems, such as technological integration, complementary renewable energy production technologies, cost reduction and emerging large-scale solar thermal technologies;
100% solar fraction during the 2015-2016 heating season, which means that all the heat required by houses for space heating was supplied by solar energy;
Constant solar fractions greater than 90% over the last 5 years, with an average of 96% for the period 2012-2016;
Solar fraction high of 92% even during the very cold winter of 2013-2014;
Very low electricity consumption, with a coefficient of performance (COP) greater than 30. This means that for each kWh of electricity, the system provides more than 30 kWh of heat;
Over the years, the electricity used for the pumps has been reduced by energy efficiency measures and on-site solar photovoltaic energy production has been increased with the addition of 18 kW in 2011. Operation is now net zero electricity for energy pumping, which includes pumping through solar collectors, district heating loop and borehole thermal energy storage (BTES);

Strong educational component with frequent site visits by professionals and students. The technology is currently being considered by several communities in Canada as well as internationally by China, the United States and several European countries.
Over 500 citations in English language journals and conference papers, theses and reports. Solar district heating is currently the fastest growing solar thermal market segment in the world.
The main maintenance issues at this point are related to the aging of the control system, the expansion o-rings of the solar collectors, and the water quality in the open-tank short-term storage tank loop (see a recent article on the Publications section). A failure of the controller caused a period of no heat for a few hours during the 2020-2021 season.

DLSC Highlights
Largest R-2000 single-family home subdivision in Canada, each 30% more efficient than conventionally built homes.
A first in the world, with more than 90% of the heating needs of residential premises covered by solar thermal energy.
A reduction of approximately 5 tonnes of greenhouse gas (GHG) emissions per house and per year.
Won the World Energy Globe Award for Sustainability 2011. http://www.dlsc.ca/

Dédéleco, we lost track

he was a little excited,

very enthusiastic about the DSLC, I think he was right on this point.

The Romans were in fact really pissed off to make tips. The majestic stone structures were sometimes of an incredible size because the pipes and their watertight connection were not mastered.

had tested lead ... https://fr.wikipedia.org/wiki/Fistule_romaine

this soft metal was not very reliable hydraulically, and gave lead poisoning.

Today we have enormous technical resources, but we do not use them sufficiently to free ourselves from fossil hydrocarbons and nuclear power.
