For an average sized house, a basic log boiler might cost about £3,000, while one with a higher standard of controls might be £6,000. A pellet-fired boiler could cost £9,000. For the total installed cost (including flue, accumulator tank, fuel store, etc), add maybe £12,000 to £15,000 to those boiler costs.
the true cost of process operation and when we are evaluating energy conservation projects. Calculating the Cost of Steam Generation The first step, which has several components, is to calculate the cost of generating steam from the boiler(s): 1. Fuel (CF) 2. Raw water supply (CW)

The cost of biomass fuel from mill wastes and urban wood wastes can range from about $0/MBtu to about $1.40/MBtu, depending on the distance from the fuel source to the power plant. Getting to zero fuel cost depends on locating a power plant in an urban area next to a wood waste processor, or next to a large sawmill or group of sawmills.
The energy requirements and outputs for three sizes of stoker boiler systems from 100 to 900 tons/day are shown in . Table 7-3. though this higher production potential comes at the expense of greater capital cost for the boiler and increased fuel consumption to reach the higher steam energy levels. 25.0 . 20.0 . 15.0 . 10.0 . 5.0 . 0.0
These represent figures for the carbon or carbon dioxide emitted by full combustion of each fuel, per unit of energy. Note that life cycle CO2 emissions depend strongly upon details of supply chains, production techniques, forestry or agricultural practice, transport distances, etc.
