It is certain that a pellet boiler with condensation is the best compromise.

In the new one, no problem to install it; but in the old one you have to have space (boiler + silo I suppose), which is not the case when you have a city gas boiler in the kitchen.

The down payment is also substantial it can slow down the enthusiasm, even if in the long term we are winning

Compromises are inevitable in terms of tolerance to a + or - large emission of fine particles.
The highly oriented suspicion aims to substitute institutional solutions for traditionally autonomous uses; it also aims to make individuals feel guilty while exempting chemistry from this questioning.
This prude bigotry (hide this particle that I cannot see! :P ), let us not forget, comes from the same people who organize the progressive destruction * of the conditions which allow life.

* Literally: by "progress". 8)

@jlt

Indeed ! It doesn't fit everywhere! So this is not a "universal solution":

- you need a hydraulic circuit: exit all those who only have electric convectors, electric heated floors, air-air heat pumps - it already makes people busy!

- all those in fact, who have no storage capacity (basement, garage, shed ...) and as you specify, those who only have a wall-mounted boiler [although I could quibble: http://www.guntamatic.fr/nc/produits/ch ... rm-5710kw/]

[but we were there on a comparison with wood, so all those were not concerned - they don't even have a flue]

- above all, there would not be enough pellets for everyone!

So: yes, you're right. This is only a topic for 2 or 3 million households!

Hello everyone,

I'm sorry but I didn't have too much time to go over the forum.

My house is 140 m² with 160mm insulation in the walls and 40mm in the ceiling and 8cms on the floor

I think I'm not too bad at insulation

The question I am asking myself now is whether installing a wood boiler (with underfloor water heating) can be more profitable or not than all-electric? knowing that I can put the electrical system but not the boiler (electrician but not too plumber heating)

How to estimate my need in kwh?

- I don't have city gas
- I'm about 900 meters above sea level so for me the CAP is an aberration
- I don't have room to put a silo unless I build a cabin


Thanks for your help

The best is to have a "historical consumption" (average of such or such consumption over 2 or 3 years) ...

Afterwards, it's only a question of converting units.

Otherwise, the data do not allow for any serious assessment. At least you need what a DEP diagnostician uses (which are not always reliable).

Afterwards, we can do with a ladle, very coarse, with a margin of error of 100%!

Historical consumption is difficult because it is new

So it's simple: if the building has been designed and built in the state of the art, it respects RT 2012 and it should be BBC.

Either about 50 kWh of primary energy per m² per year [depending on climate zones, in fact from 40 to 65], or therefore, on average, a consumption of 7 kWh per year (000 x 140; to be adjusted to your area)

Or 700 l of fuel. Or 1,4 tonnes of pellets.

But in electricity, you will only be entitled to 7 / 000 or about 2,58 kWh.

Thank you for your answers

At the time of my building permit, RT 2012 was not taxed

Can you explain to me why you do "7000 / 2.58"?

Thank you

It is a correction on electricity to switch to primary energy. In France it takes on average 2.58 kwh of primary energy to make 1 kwh of electricity.
