Disillusioned by closed hearth that does not warm enough




by fafane77 » 17/10/10, 18:00

Hello everyone,
I defer to those who heat their homes with wood.
In August I installed or rather installed a closed fireplace with a heat distributor in the attic.
seguin brand fireplace should be a benchmark if there is one in the world of the fireplace with a double combustion option.
my problem is as follows, it does not really heat up as I hoped. It is a 13kw all cast iron hearth which goes up to 15 kw with double combustion. My house is rather recent dating from 2005, insulation rt 2000 approx 110 m² living space. All the people I know possessing an insert heats all the house with?
Would the pathologist underestimate the necessary power?
I am a little disillusioned today, not knowing what to do, if someone has similar equipment, some explanations will be welcome.
thanks in advance

15kW ca should be enough.

What do you heat with fuel and how many kg per day?

I may say something stupid: but a stove will never heat more than what it is given to "eat" ...

I heat with three species of wood, birch for lighting, oak, ash and beech for the rest.
when the quantity I find that I consume a lot for the little rendering, for a day like today for example I am in a dozen logs with very large.

Have you ever fired with wood before? Sorry but "not bad" is a bit vague ... as a quantity ...

1 cubic meter of beechwood 400 - 450 kg dry = 2000 kWh = 200 L of fuel oil.

A thermally inefficient house can easily consume 20L of fuel oil per day, i.e. 1/10 of a cubic meter. After recess it depends on the T ° and surface to be heated ...

Take the test by weighing your consumption of logs over several days ... you can easily do this with a scale.

it is indeed the first year that I heat myself with wood. I have a lot of colleagues who only heat their houses like that and in addition to larger areas and no distributor in the attic. I bought ten steres and I see that it decreases super fast. While my colleagues tell me to be too hot and open the windows even in winter I am a little disgusted to say the truth especially since with us last winter it went down to -17 °.

It's hard to compare 2 houses with a ladle ...

What is your level of insulation? Is your wood dry?

How much and how much energy did you use before?

i have a recent house rt 200 from 2005
I just moved in since July, do a lot of things. I chose wood because it is electric at the base and I do not want to pay like my neighbors 200 euros of elec per month. I even changed the convector crap by radiating high-end black panels and put a programmer on pilot wire I would like to use this as little as possible

RT2000 ok had not read in the 1st message.

But therefore you must have received a DPE during the house session, it's the law. What's he saying ? You have an idea of ​​kWh / m².year and you just have to multiply by the surface and you have kWh and then a conversion to obtain equivalent stereas.

It is approximate but it will give you an idea of ​​your future consumption.

Otherwise: simpler look at your counter, about 80% of consumption will be that of heating, just divide the age of the house and you have an idea of ​​heating consumption.

Considering your house and surface, you will probably be between 20 and 30 kWh / year ... so 000 to 10 cubic meters should actually be enough.

is the chimney draft correct (sufficient pressure)
it can be measured!

now the quality of the fuel has a lot to do with the quality of the heating

Well I think that if the wood burns (and quickly) it is enough ... maybe even too much ...

Yes for the quality of the wood, I said it above ...
