How long will a 15kg bag of wood pellets burn?
Wood pellets provide environmental and economic energy solutions for private and commercial real estate.
Wood pellets are the perfect choice for use as fuel because they are renewable and cost-effective. The dense particles provide high energy output, helping to provide renewable energy for homes and buildings.
An approximate guideline is that 1 tonne of wood pellets will produce 4,800kWh of heat. This assumes the wood pellets are being burnt efficiently. This means that a small house in the Australia may only need 2-3 tonnes of pellets per year.
- Small House / Flat – gas usage of 8,000kWh and an electricity usage of 2,000kWh
- Medium House – gas usage of 12,500kWh and an electricity usage of 3,100kWh
- Large House – gas usage of 18,000kWh and an electricity usage of 4,600kWh
The average cost per unit of fuel energy of wood pellets is 4.2p / kWh. This is lower than that of both heating oil (6p / kWh) and bulk LPG (7.6 / kWh).
The operating costs of some major energy sources are shown below.
- Wood Chips (30% Moisture Content) 2.9 pence per kWh
- Wood Pellets 4.2 pence per kWh
- Natural Gas 4.8 pence per kWh
- Heating Oil 6 pence per kWh
- LPG (bulk) 7.6 pence per kWh
- Electricity 14.5 pence per kWh
Most wood pellet stoves can also operate on a thermostat whereby you change the heat setting depending on the time of day. This can help ensure you are only heating your home when you need to.
According to the Pellet Fuels Institute, a 15kg bag of pellet fuel can provide up to between 15 to 24 hours of solid heat. A winter’s supply of wood pellets is about 150-200 bags—however，Dosage depending on climatic and lifestyle variations
15kg bags are a good size and if you prefer to buy in bulk, you can think about storage. Wood pellets will last indefinitely as long as they are well kept and don’t get wet.
