Boiler prices ökofen: why is it so expensive?

Heating, insulation, ventilation, VMC, cooling ... short thermal comfort. Insulation, wood energy, heat pumps but also electricity, gas or oil, VMC ... Help in choosing and implementation, problem solving, optimization, tips and tricks ...

Yep, that's about the time it takes to heat DHW for 24 hours ...

But what do you mean by that?

ps: on the dlsc site there are many photos but always from afar http://www.dlsc.ca/photos/2010/january/jan12_index.htm and their film is computer generated images: http://www.dlsc.ca/animation.htm

The wooden ideal is the mixed boiler wood pellets which combines the two (in the same price range) which allows to burn all free wood and the free plants that we throw everywhere and that I see in huge quantities around my home !!
To start with me and my neighbors who burn this waste in the open air by smoking for days !!!
I just have to collect them, dry in the strong sun and burn in winter.

I did not manage to burn all the wood abandoned in the storm of late 1999 around a home, before it rotted !!

So try to burn free lost wood !!!
Since consumption in Euros can become zero, then the investment will be amortized much faster !!!

Google earth and street view lets you see the real photos in Cagliari and Drake Landing as everywhere in the world !!

This is how I understood where they are !!

Otherwise with only 15m2 of solar panels per house, we can improve in summer for peanuts with additional summer collectors at 20 € per m2 and remove any heat pump or annex gas in France much less cold !!!!


So stop bashing and be constructive !!

There is an urgent need to decrease CO2, the earth is warming much more than in 1976 with the drought !!

So make your subject and we talk about it! We don't criticize, we ask ourselves questions. Nowhere have I seen any talk of costs !!

Do you have precise coordinates of all their subdivisions?

It's not 15m² it's 30m² (because 1.5 MW = 1600 to 1800 m² = 800 panels larger than 2m²) ...

Is that so ? I thought there was a good technical reason ...

That solar coupling was almost essential in a pellet boiler (and even more wood in general) so as not to clog it and spoil a lot of calories in summer when the boiler is operating at very low average speed?


1) They are fully designed for ("summer" mode with only programmed DHW preparation).

2) Indeed, it is not very "elegant", all the more so as the output drops (the water in the boiler is heated up to hot times, heat which is lost).

3) I think this is a sub-optimal operation which can reduce the life of some parts (like driving no town "wears" the clutch) ...

4) But even with a yield of 50%, with a kWh at around 4,5 cents of euros, the CESI, relaised by a craftsman (I'm not talking about self-construction), costs too much. At best, in 15 to 20 years, you get the bet! Must be convinced (and not too dry on the side of the banker).

I installed it when my boiler was on fuel. There, I planned to recover the stake in ten years. Obviously, I have not thrown it even if it will take me 15 years or 20 ... And I am happy to shut down my boiler almost completely in summer (except one or two periods of dark weather too long).

on google map type:
drake landing Okotoks, Alberta, Canada
or:
drake lahttp: //maps.google.fr/maps ct = resetnding? Okotoks, Alberta, Canada

http://maps.google.fr/maps?num=100&hl=f ... CCAQnwIwAA

So make your subject and we talk about it!

already done :

and google street view photo of solar panels and houses of Drake lading solar community on Drake Landing Common next to Drake landing road on Milligan Dr towards South East in the center of Okotoks Alberta Canada

Oh no Dede! This subject https://www.econologie.com/forums/stockage-e ... 10470.html it is that of Obamot that I personally split from another!

It does not speak SPECIFICALLY about the Drake Landing Solar Community solution!

I insist on the fact that it is necessary to make a specific one ... really it is for "our good" to all!
: Cheesy:

Edit, it was done, here it is: https://www.econologie.com/forums/chaleur-d- ... 10828.html

Thank you very much!

To return to our sheep, take a look at the HS France site: http://www.hsfrance.com
there is a very interesting pdf with multi fuel wood boilers and hydro accumulation ...

If 3) is true, investment in CESI can pay for itself more quickly thanks to the savings on boiler wear, right?
In fact, to compare, we would have to calculate a cost per kWh including the investment and maintenance of the boiler ...

I don't think "boiler life" is measurable! This must depend on so many factors: maintenance, humidity of the cellar / boiler room, settings, cycles, obsolescence (in the sense of "much more sophisticated machine that appear on the market: condensation, etc ...), drop in efficiency ...

To continue my story of car wear in the city: is the impact measurable?

So I would say that "logically" this is not conducive to sustainability but I do think it has a measurable impact on the profitability of a CESI!
