Clim reversible inverter Carrera Bricoman the savings?

[Capt_Maloche]

non-residential lighting is for offices, ok indeed

To reach 50Kw.h / m² a year you have to have positive sources of energy, it's a balance

the energy of winter solar radiation is taken into account in the calculation where the importance of the exposure and glazing surfaces, the contributions of solar panels, Canadian wells ...

and it is a ratio to m²: if you have too much outside surface for a small floor area, you do not pass, I had the case on a small poorly exposed pavilion which is more


In short, the architects will have to take all these factors into account for their designs, and we are here to assist them.

Now there are again several discussions on a single thread. It would be nice to create a discussion dedicated to habitat labels and leave it to inverter clims. Christophe, would you mind?

[Christophe]

+1 with Christine ... but I couldn't help myself then it's not 100% HS either ...

In short, the architects will have to take all these factors into account for their designs, and we are here to assist them.

Ah yes if we count the energy produced in the house it is obviously attainable ... it will cost less than looking for passivity for the same result!

By putting 20 m² of PV (ideally PVT) in each new construction, we could achieve this easily ... without too much worrying about "climatism" and insulation even if these 2 points are essential! Because when it comes to air conditioning, don't ask too much of the "chain builder" of cinderblock houses with the minimum legal insulation ... which still constitute 90% of new houses!

At the price of current housing, (prohibitive and highly speculative in certain regions) 20 m² of PVT, that's less than 10% of the price excluding VAT of a house ... excluding land and costs !!

Obviously we prefer to buy a new car ... than to put solar, ah the world of consumption is "well" done ...

[Capt_Maloche]

Yeah, Christine rightly, we should talk about this on a subject dedicated to Thermal Regulations
here for example: https://www.econologie.com/forums/post145504.html#145504

to go back to that:


and concerning the water recovered in winter at the level of the external group, it is super clear and has no apparent deposit

at worst, it's good for plants, 5L / day anyway

Hello everybody

After 3 months of operation, the financial and energy balance is very satisfactory

Here are the records of my fuel oil consumption since 2007 and the electrical consumption of my reversible air conditioning since the start of winter:



Well it's not bad:

at the same period last year I had consumed 900L of fuel oil
This year I am at 500L with the air conditioning in heating mode to which must be added the consumption of air conditioning

Is :
Winter 2008/2009: 900L x 0.80 € = 720 €
This winter: 500L x 0.80 € + 794 KW.hx 0.10 € = 479 €

Over the half of the heating period, I have already saved 241 €

So I will make my purchase profitable in less than 1 year and a half

Thank you for this feedback.

I find your cost price kWh electric low ... you consume a lot and at double price.

[Did67]

Or is it a "marginal cost" ??? (= the cost of an additional unit). Maybe you consider that all the other costs are already paid (subscription, etc ...) by the fact that you are connected anyway ???

That said, there are still all the small taxes and contributions at the bottom of the bill. Is it included?

[Christophe]

All right, but it sucks well anyway! You consumed more in 4 months than our solar pump in 2 years ... but hey it was predictable!

Do you have an idea of ​​the negative T ° COP as you currently do, using the same method as you used above?

And the COPA over the year (at the end of the heating period) would be good too! Assuming that what was brought in by the cap was saved in fuel oil.

And in Sivouplé Primary Energy?

It would give 200L fuel oil saved thanks to the CAP ... according to:

Winter 2008/2009: 900L x 0.80 € = 720 €
This winter: 500L x 0.80 € + 794 KW.hx 0.10 € = 479 €

Are we doing a CO2 assessment too or are we burying ourselves?

ps: to do really well, would still have to bring everything by DJU right? I think you have access to DJU from your home

Thank you for this feedback.

I find your cost price kWh electric low ... you consume a lot and at double price.

Yes it should rather take 0.12 € / kWh ... French average. 0.11 if double tariff.

[I Citro]

Yes it should rather take 0.12 € / kWh ... French average. 0.11 if double tariff.

With gas heating, I consumed little electricity, around 4.000 kWh / year. It came back to me at just under 0.15 € / kWh including tax subscription in 2008.
In 2009, I went to 7.000 kWh which caused the price of kWh to drop to € 0.14 including VAT, simple subscription price 9kW included.

For 2010, I plan to consume 9.000 kWh (2 electric cars over a full year) and I will switch to double tariff.

I hope to get closer to the figures you are announcing.
