Fuel cost is usually the dominant component, accounting for as much as 90% of the total. It is given by: CF = aF x (HS hW)/1000/η B where aF = fuel cost, ($/MMBtu) HS = enthalpy of steam, Btu/lb hW= enthalpy of boiler feedwater, Btu/lb η B= overall boiler efficiency, fractional.
Wall Mounted Boilers, Water Boilers and Instant Water
Total cost of the boiler, buffer tank, flue, labour & VAT came to £15,590 minus £1000 from the (then) Low Carbon Building program grant. We use bagged wood pellets and need just under 5 tonnes a year. They cost about £230/tonne (delivered + VAT) working out at £1100 pa approx. We take three tonnes per delivery with about two deliveries a year.
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.

Waste-to-energy plants may have a significant cost advantage over traditional power options, as the waste-to-energy operator may receive revenue for receiving waste as an alternative to the cost of disposing of waste in a landfill, typically referred to as a "tipping fee" per ton basis, versus having to pay for the cost of fuel, whereas fuel cost can account for as much as 45 percent of the
