What will be my future consumption of pellets and especially its cost compared to fuel oil?
Heating with wood pellets (or pellets): Questions to ask before choosing this method of heating?
Your consumption of pellets will obviously depend on your energy needs. If you know them, then it will be easy to estimate your pellet consumption.
For this, we have developed in detail several methods on the page well size its wood boiler which we summarize here.
Method 1: Do a complete thermal study
Thermal studies will give you an estimated consumption in kWh per year.
If so, simply divide by 5 to obtain about your needs kg pellets.
Examples: a house 150 m² has an energy requirement of 100 kWh / m².year will need 15 000 / 5 = 3000 3 kg of pellets = Tons per year of pellets.
Method 2: Use Your Current Gas or Fuel Oil Consumption
The equivalence is very simple: 2 kg of pellets = 1 L of fuel oil = 1 m3 of gas.
Examples: if your consumption of oil 2500L, you will need to 2500 2 * = kg = 5000 5 tons per year of pellets.
How much will I earn compared to fuel oil?
Everything depends on the price at which you will find your pellets (see Why choose wood pellets?).
Suppose you touch the pellet 200 € / t delivered (price generally found in 2007) and the oil for € 0,65 1000L.
kWh prices would therefore:
- € 0,04 per kWh for pellets
- € 0,065 per kWh for fuel oil.
By switching to pellets, you can therefore reduce your energy bill per kWh from € 0,065 to € 0,04, i.e. by almost 40%!
In other words your energy bill can be almost divided by 2, but beware of the stability of the price of pellets if they are not (yet) regulated and this unlike fossil fuels. See the discussion future price of pellets?
