Little calculation with hindsight over a year of gas consumption




by fabio.gel » 06/01/13, 20:34

I take a little time to do a quick quick calculation:

From what I saw a known site

http://www.quechoisir.org/equipement-de-la-maison/amenagement-chauffage/materiel-de-chauffage/decryptage-poeles-a-granules-le-cout-du-kwh-compare-aux-autres-energies

From the above site:

Prices per kWh are established according to the calorific value of each energy, which makes it possible to compare their real cost of use. Calculated inclusive of VAT, the price per kWh includes the amount of the subscription most suitable for heating in the case of electricity and natural gas, that of delivery in the case of fuel oil, propane and wood. The propane tank is consigned. The kWh rate used corresponds to a single house using this energy for heating and hot water production.


So I leave with these values ​​and I calculate (if I burn myself sign me)

I consumed 3178 Kwh of gas which includes cooking + water heating

I start on the assumption that 2/3 go to heating water (ladle)

So a big consumption of 2120 Kwh for water heating.

According to the graph above:

Gas: 2120 Kwh x 0.73 € / Kwh = 1547.6 €
In electricity: 2120 Kwh x 1.364 € / Kwh = 2891.68 €
In pellet: 2120 Kwh x 0.525 € / Kwh = 1113.00 €

If I switch from gas to pellets to produce my domestic hot water the financial gain is € 434
On the other hand if I switch from gas to electricity ouch ouch ouch ouch
Electricity is really too expensive to heat water.

So an investment in a hydro pellet stove seems to be a good solution.

What do you think ?

A comma must have spurted up a notch (unless it's over 10 years?)

I shift the decimal point by a number ... over a year:

Gas: 2120 Kwh x 0.073 € / Kwh = 154.76 €
In electricity: 2120 Kwh x 0.1364 € / Kwh = 289.168 €
In pellet: 2120 Kwh x 0.0525 € / Kwh = 111.300 €

It seems more realistic : Mrgreen:

You should add the investment costs and depreciation over 15 years.
And I think in this case the gas is more interesting
