I remember the solution proposed by the company Econo Gembloux (no, it's not even a friend) where the energy is stored in the soil under the slab. This is combined with a heat pump, which works with a good performance, because it will look in a heat so to 15 ° C. heat is supplied by a dozen square meters of solar panels.

(Econo.be)

That said, it is right without interchange point salu (BRITE) :D Otherwise Helo legionella, salmonella, etcetera-ose. :D

Ch Hi-ose :D

Indeed, with a heat pump, why not, but it is far from independent

Article of the day about the CAP: https://www.econologie.com/geothermie-po ... -3900.html

A neighbor on the cost in Primary Energy will come ...

Econo are funny ... I wish I knew how much it installs CAP in the province of Luxembourg or kWh is € 0,25 (equivalent to fuel oil prices of € 2.5 / L !!) ...
: Mrgreen: : Mrgreen:

ps: how should it flows concrete m3 to have an acceptable buffer?

1) asked!

2) is not concrete, the ground!

I not moved, I command and I advise to consume as little as possible, well, I'm making a 600m² administrative building with heating max needs 20KW

It is true that point of view back to primary energy, the actual performance of a CAP is 1.5, I would not stay on CO2 appearance and treatment of waste plants ...

but at the purse, with oil at 1 € per liter, it becomes attractive if its PAC is dimensioned to support 80% of current needs, complement by a wood insert.

My case is special because I can have this equipment at factory prices and I install myself (business requires)
suddenly I will surely equip myself for this winter unless 3000 € all inclusive, with ECS. (The price to fill my tank for a year)

at that price, I intall pays off in less than 1.3 years
Obviously the price of delivered and installed market of such a facility is paid rather in 9000 € and ROI in this case passes 4ans, which still remains reasonable with a life expectancy of the equipment to 10 15ans

very clever today who can say how you expect the price of electricity in France KW.h

Advanced projects




by sensei64 » 10/01/10, 20:03

Hello everyone

or are your projects in the field of inter-seasonal storage?

made, abandonment studies?

thank you for your answers with your positive and negative discoveries

Well we have the thermal storage solution with MCP (Phase Change Materials), provided a well-insulated house (Recent, minimum RT2000)

Hello
had seen on an isolated concrete slab with post styrodur such as outdoor terrace with sun sensor has air circulating within and medium core cans 30l aligned and embedded in the concrete to increase the amount of storage
it would be boring to know what could be stored for a volume of 30m3 less water (2,5x 2,5x 5) with let's say in 20 cans 25L

grosso in Merdo entry of Canadian well, it should well bearing the remains of a small temperature for daily absences (job :( ) In a sunny area

For info we discovered Insulation with our new house.

And we were very very very surprised to be able to heat 150m2 on one level without any problem with a small stove Cast Flame Ilam 7kw (it was in place when we bought)

https://www.energie-rama.fr/catalogue/a ... w_359.html

At this point we ordered 5 stere 250 € for the year.
At first glance we should finish at ... 6, 7 or 8 steres? in all (to follow)

In summary (and to our surprise, bis) it seems to us both simple, tried and cheap to get hot: which does not prevent all the thermal innovations (that makes sense)
