My bio-climatic house

[jean63]

OK, thanks. I will pay attention to your advice.

Concerning the heating wall, the tube PER diam. 12 is fixed on the walls with electric jumpers diam. 12. A nergalto (sort of expanded metal used by the plasterer) is fixed in front of the sheet of tube and constitutes the hook and the frame for the coating of plaster (35mm).

I actually need to change the file names because the linux server does not tolerate special characters.
I update it and give a photo of the nergalto and the plaster coating.

You have seen my big cistern. It is a BM balloon from Sodidat used in industry and large tertiary for the recovery on the condensers of cold groups in order to make hot water necessary for cleaning (example large surface).


Regarding my heat production system, the energy used is solar (10m² viessman vacuum tubes) with wood fill (insert). The solar panels (which I have not yet installed), will feed an 90kW exchanger in the bottom of the big ball of 1000l which constitutes my reserve of energy (storage between 40 and 80 ° C).
At the top of the flask, another exchanger of 40kW ensures the production of hot water in instantaneous. This hot water is sent to a cumulus that maintains the temperature and the extra if necessary.

The water contained in the volume of the flask (10001) is sent to the insert which in operation makes it possible to recover 25kW. The insert recovery system consists of 4 exchangers and represents 150m of 12 / 14 copper wrapped around the firebox, the smoke box and the flue.
An 3 channel valve makes it possible to vary the flow rate in the insert according to the return temperature. A flap at the top of the flue closes the draft according to the flue gas temperature.
The goal is to slow down the passage of fumes in the conduit to promote exchange.
In the event of a pump shutdown, safety allows the pump to send cold water into the outlet and to discharge the boiling water to the sewers (supply valve and discharge required on any solid fuel system).


Another flow on the tank constitutes the heating circuit, a valve 3 channels regulates the flow temperature according to the outside temperature with correction by internal probe.
The entire system is controlled by a PLC control type controller from Johnson control with connection on the PC to control, configure and manage the logs.

It's a great system that I enjoy experimenting. After analyzing the system in operation, I am able to optimize it by simplifying it to reduce the cost.

No use of electrical energy by circulators and regulation (150W).
This winter has been a pleasure for me and my family and despite the fact that I do not have solar panels yet, the stress of the wood has not been huge (12m3 for 220m²).

SUPER, bravo, award of excellence,

this is a real bio-climatic house she will be No. 1 top Kyotome, the site that has just opened!

I will have a lot of information to ask you; at home where I live from then 17 years, the power of the pipes of the soil is done thanks to a gas boiler, but I think for the future to a solution solar + storage + insert wood (I have a fireplace hearth closed).

For now I have been satisfied with the underfloor heating by paying a little gas to GDF.

I would like to know the prices of the sensors, the cistern, the installation of connection and the system "insert wood / heater", but to be discreet (if you prefer) one can communicate by private message (it is necessary to click on mp and write his message by putting a title (required).

Thanks again.

[Manuel]

Thank you, I used a lot of energy to realize this project and your remarks fill me with joy.

What do you mean by solar storage?

I do not believe in long-term storage, even tiny losses inexorably discharge the energy accumulated during the summer period.

Estimate of expenses
Sensors about 3k € - 50% tax credit
The balloon about 3k € - 50% tax credit
The installation of the gas + plumbing plant about 10 k €
Insert 850 € at casto
150ml copper 12 / 14

These are prices discounted because my fluent BET profession leads me to communicate with suppliers and companies.

Overall cost of the house with land (6500m² - 30 k €): 116 k €
This budget is low because I did everything on my own by earthmoving (1650m3 of displaced land) and the carcass made in 3 weeks with a young carpenter to help me. The rest on weekends between seven 2004 and April 2005.

Price to pay in addition to 116 k €: Good cervical blocking during 4 months and significant drop in my work performance.

[jean63]

For the cost it is also: hat! Damage to the cervical! I know that too.

Regarding solar storage, I simply want to say that when there is sun, the hot water obtained is stored in the tank of 1000 liters ... .. and it can be returned within one day, or the 2 days?

For the rest of the time, are you obliged to light the insert to have heat inside?

Tax credits (50%) are deductible only in new constructions? Is not it necessary to have the work done by a pro with VAT invoices to present to the taxes?

With a medium fire in the insert, at what temperature does the water come out of the copper pipe?

Once again, congratulations. I would have to build today, I think that's what I would do, although for the wood it's a bit restrictive, but it's a choice.

[gil67]

superb achievement.
I hope to be able to get started, since the time that I prepare my project, before 2007. But given the price of land at home, the land is more expensive than home, I have to negotiate again.
What is your house?

Surface: 220m ²

for jean: For now, I have not invested in solar panels, so I maintain the temperature of the ball with the insert.
The temperature varies between 20 and 80 ° C.

At medium heat, the return temperature is 20 ° C higher than the flow temperature.
This data varies with the flow sent into the insert, when the fire is sustained, I increase the flow and the delta T is the same.
The autonomy is from 1 to 2 day after the outside temperature and the amount of sanitary water drawn off.
When I installed 10 m² of vacuum panels, I think the need to make fire will be reduced by 50%. During sunny periods, even cold, I could maybe hold 4 or 5 days without making a fire.

For the tax credit, it is sufficient to notify an investment in its return, the repayment is automatic and concerns the equipment that uses renewable energy, whether the house is new or old, the energy saving effort is the same.



Good luck for Gil

Manuel (It was also my father's first name)

This name is well worn in 2 cases (think before acting and do not be afraid to launch)!

For the tax credit, it is sufficient to notify an investment in its return, the repayment is automatic and concerns the equipment that uses renewable energy, whether the house is new or old, the energy saving effort is the same

OK, but I read that it must be done by an authorized installer with the installation invoice by this installer. I saw sensors (2 m2) to 185 euros ald 300 euros promo, I would have bought 2 to install myself a hot water production, but from what I understood I can not count them as a tax credit. Otherwise, I would have made 2 once a saving!

At this price I hesitate to buy 2 anyway without tax credit. These are not vacuum sensors, I give you the website address in private message (here it is forbidden because it is a commercial site) and you tell me what you think.

Thank you for all this information.
