Biomass Boilers and Heating Systems

What is Biomass Heating?

Biomass heating is when normal fossil fuels like gas, oil or even electricity are replaced with wood fuel like logs, wood chips or wood pellets.

How can burning wood products be good for the environment?

Fossil fuels like oil and gas cannot be replenished. When they have been burned and they release harmful carbon dioxide (CO2) into the atmosphere. Electricity is commonly produced by burning fossil fuels. Biomass is a renewable source of energy meaning new trees can be planted to replace the ones which have been used as biomass fuel. Although burning biomass releases CO2 to the atmosphere, this is offset by the CO2 absorbed in the original growth of the biomass fuel making this source of fuel carbon neutral and good for the environment.

What are the benefits of Biomass Heating?

  • Up to 70% cheaper than other fuel costs.
  • Commercial and District heating installations could be eligible for RHI payments.
  • Return on investment can be as high as 25% per annum.
  • Biomass boilers are more efficient than fossil fuel boilers.
  • Quick payback with average being 3 to 5 years.
  • Utilise your own wood supply to cut fuel costs.
  • Heat multiple buildings from a single installation.
  • Fossil fuel prices rise much faster and higher than biomass fuel costs.
  • Lower your carbon footprint.

How does a Biomass Boiler Work?

Biomass Boilers work just like a conventional fossil fuel boiler except they burn biomass fuel.

A biomass boiler can be connected to your existing heat and hot water delivery systems.

Types of Biomass Stoves and Boilers
Wood Burner Heating Stove

Wood Burner Heating.

Wood Burning Stove

  • Used to heat only one room usually.
  • Pellets or logs are used in stoves.
  • Does not heat hot water.
  • Won’t qualify for Domestic RHI payments.
  • Various styles including traditional, contemporary and inset.
Biomass Fire Heater

Biomass Fire Heater.

Wood Burning Stove with Back Boiler.

  • Pellets or logs can be used.
  • Can provide heat and hot water to the property.
  • Can qualify for Domestic RHI income, if using pellets.
  • Various styles including traditional, contemporary and inset.

Domestic Biomass Boiler and heating

Domestic Biomass Boilers.

Domestic Biomass Boiler.

  • Will usually be fuelled by logs, pellets or both.
  • Option of either automatic or manual fuel feed.
  • Can provide heat and hot water to the property.
  • Can qualify for Domestic RHI income.

Efficiency Helps Reduce Fuel Costs Your current boiler system is probably a number of years old and costs a lot of money to run. It’s efficiency level of how it burns fuel could be as low as 65% or even lower! Modern Wood Heatings Systems are

Over 90% Efficient! Biomass Boilers are super efficient heating systems.

A biomass boiler is a boiler designed to burn solid fuels classed as biomass. Such boilers can be supplied to burn every form of biomass from woodchips, wood pellets or logs to waste agricultural materials such as straw and grain husks, olive kernels, rice and the dust from any of these including sawdust.

Boilers need to be designed to burn specific materials, with any given boiler able to burn a limited range of biomass. Biomass systems come in a range of sizes and typically burn wood pellets, wood chips or logs. They provide space heating and hot water to domestic, commercial and industrial users. Modern, efficient biomass heating systems are computer controlled, easy to maintain and operate and are common throughout Europe and Scandinavia.

A biomass boiler is an ideal replacement for an existing boiler powered by gas, oil or LPG. They operate in a similar way totraditional boiler systems, are easy to clean and maintain, are reliable, they improve efficiencies, significantly reduce costs and are better for the environment.

The only main difference between a biomass boiler and a conventional boiler system, is the delivery of fuel.

Average Current Fuel prices

per kilowatt Burned

Woodchip (30%MC) 2.2p (per kWh)
Log (30%MC) 2.5p
Wood Pellet 4.2p
Oil 6.7p
LPG 7.9
Electricity 14.5p

So by switching from LPG to Log you would cut your fuel bill by 68% and when you factor in that your new biomass boiler is likely to be around 30% more efficient than your current boiler then it really is a no brainer!

Renewable Heat

It’s financially rewarding to go greener!

In order to try and achieve their ambitious carbon reduction targets, the Government are now financially incentivising home owners and businesses who opt to use renewable heating technologies. Some of the technologies used are biomassboilers, solar thermal panels and heat pumps to heat their properties. This scheme is called the Renewable Heat Incentive (RHI). Although the RHI is aimed at properties with no mains gas who burn oil, LPG or electricity it is still open to on grid gas properties.

The scheme has been divided into two parts.

Non Domestic RHI and Domestic RHI. Here are some of the highlights …

Non Domestic RHI

  • Launched in November 2011.
  • Aimed at businesses, schools, hotels and leisure facilities etc.
  • Your business earns money for every kilowatt of heat produced.
  • You will receive these payments quarterly.
  • The payments will last for 20 years from the date of installation.
  • Communities with a district heating system are eligible for payments.
  • Return on Investment could be as high as 25% per annum.

Domestic RHI

  • Launched in April 2014.
  • Will be open to owner-occupiers, private landlords, registered providers of social housing, self-builders, third party owners of a heating system and those who have already installed a system which meets the criteria.
  • You earn money while heating your home.
  • You will receive these payments quarterly.
  • The payments last for 7 years from the date of installation.
  • Return on Investment could be as high as 25% per annum.

RHI Example
Commercial RHI

Boiler size 199kW
LPG costs  £18,731 per year ( current )
Woodchip costs £7,048 per year ( estimated )

RHI income £19,873 in year 1 ( 20 year income  £534,000)
Payback period 3 years

Total Projected Income & Savings Over 20 Years is £952,000

Domestic RHI

Fuel savings £624 in year 1 ( 7 year saving £6447 )
RHI income £3,050 in year 1 ( 7 year income £23,371 )
Payback period 5 years

Total Projected Income & Savings Over 7 Years is £30,000.
