Chaudiere wood logs Froling FHG Turbo 3000, price quotes

[dirk pitt]

then Jean-Paul 2 and I retain 1 (I love this one)

wow, it's true that it's cold over there. in my list of DJU, I besancon: 2900DJU, mulhouse 3000DJU and colmar 3000DJU
I would say that being at 650m altitude, the severity of the climate must be at least as much as Colmar or more. I took 3300 for my calculation.
2200L it's about 22000kwh and 12steres it's about 19800kwh. 0.7 has a medium yield (logs + fuel + radiator circuit), and an intermittency at 0.6, it gives us a loss of your house of about 1.75W / m3 ° C which is not great.
for info of the new isolated correctly gives in the 0.7
of the former isolated moderately gives in the 0.9 to 1.3 and the old evil or not isolated gives in 2 to 3.5
to see if my calculation has the big ladle is correct but it seems that you can do better in terms of isolation. I remind you that this calculation takes into account the rigor of the climate and is therefore comparable everywhere.

Now, with these existing losses if you still want to have 19 ° C by -20 ° C outside, you need 24KW.

it would take a boiler 25KW but with 30 and a big buffer tank, it must go. the ideal would be to isolate to go down the losses and pass with an 20Kw

Thanks for all the details !
If I understand correctly, the proposal of my heating engineer is not so crazy!

There remains the problem of insulation. In theory, I should start with this but my wood boiler is at the end of life so I will first invest in the boiler assuming that the insulation performed later is sufficiently effective ...

One more question: a big balloon is 1500L or more?

And finally, (rather for Tigrou_838 but it's open!), What is what in €, an investment in solar heating floor + solar water coupled electrical?

Thank you for the time spent on all this, I imagine that your installation (Dirk pitt) is satisfactory? And I still have a question, you answer on the forum every day with the same precision?

thanks again

Balloon 1000L is minimal union, it seems to me but I am not a specialist to calculate the volume of the ball.
for insulation, that's for sure the best. on the other hand, it may be wise to choose a less powerful boiler 25 20kw or even that will work at full power with good performance but the max power being reduced, consuming less wood.
you have also looked at the UNICAL or MORVAN boilers that work in reverse but in natural draft (no need for a fan)

we did not talk about the regulation but it also plays a lot on the conso. especially the outdoor probe in areas with large temperature differences (which is your case)

for solar heating, I let meet the specialists.

the answers, it is with pleasure .... but when we are there.

hello foxmk,

for more info, the site econologie is very well looking for a little, and for a complement, the site apper.

look at my signature and you will have answers to all your questions at solar level.

Hello

For the calculation of the autonomy that allows to achieve a buffer tank "full" of heat, it is necessary to know the minimum temperature which still allows heating, or at least to maintain a suitable temperature in the house on a rather cold day.
In this case, a floor heating is more interesting than an installation with radiators. But it is a test that will tell if 30 °, 40 ° or 50 ° is the minimum value.
Then, it will be assumed that the maximum temperature of all the water contained in the buffer is 90 °, or more likely at an average of 80 °, given the stratification.
Then, to your calculators.
As a reminder, 1 liter of water may contain 4.18 Kj / Kg.K

I do not have grato wood but it is the energy that I want to keep in case the price of pellets climb, especially since I could consider cutting myself the wood if it too became very expensive. .. (splicing ...)

That's what I feared too ... in 2006 but the future gave me wrong, look at this topic: https://www.econologie.com/forums/pellets-et ... 82-10.html

If there was to be a coupling with the fuel oil, it would have already occurred!

In addition I think that pellets will soon be regulated, unlike wood where everyone sells at the prices he wants (and often black ...)

So I stay on my wood position but if I understand correctly I must change boiler brand see heater?

Yes but this is only my opinion ...

For the heating engineer not necessarily, just ask him to offer you another brand ... cheaper!

Do you have an idea of ​​the price of a combined solar-fuel or solar-wood-fuel or solar-wood installation for heating and sanitary water?

Thank you

Uh you still have a fuel boiler? In this case it changes everything ... you could do the wood riser and only turn on the boiler fuel very cold! So you can take a smaller boiler!

For your price, hard to say: between 10 and 15 000 € TTC without deduction of aid.

Solar wood is the best solution, we are more forums to have it.

Hello
in your corner (the jura), there is a company that offers sets boiler (vigas: rustic but inverted combustion) and balloon (solar bayer made in germany) with accessories of the same brand, the site is http://www.hot-comb.com/ for info, I do not have any stock at home (and elsewhere either )

Ben right now better not to have any action

Here is the complete catalog of the site (waw the design) that you quote: http://www.solarbayer.de/download/Preis ... ternet.pdf

hello, to answer the little question of foxmk

"" And finally, (rather for Tigrou_838 but it is open!), What does it represent in €, an investment in solar with underfloor heating + solar sanitary water coupled with electricity ""

at home, configuration as you just said, if you go through a pro, between 17000 has 18000euros, it cost me in total has a chouia near 5000euros all inclusive.

the calculation is done very quickly, through APPER group purchase for the gear, and do even, no need premiums (yuck) or others,
and in the end it costs even less and especially less emerdement. (bank, administration)

solar greetings

Hello to you guys
how can we advise a person to take a really bad FHG3000 advises seen on a forum. While the price is high but to have compared such machines froling, ETA, KWB to HS or CTC or others, the latter arrive at the customers with welds poorly clean or already rusted by rust and do not talk about regulators !!!!! (if there is one)
Me the advice that I give you will seek you one of the boilers quoted above but especially not of HS or CTC you take it in 30Kw 1500 to 3000 liter of tampons and for the moment the solar one leaves it, after you isolate well your house and you will see in periods of great cold (-10 -15) you load one to one and a half times your boiler per day and in between season a load every two or even three days you can even do the ECS in summer a load by week. And if you are fed up you make a solar on the ECS (even heating extra if you won the Lotto until)
It remains to find a correct installer but it is already a good sign that he advised you a FHG
