Froling biomass boilers

Froling have been developing wood heating technology since 1961 and have cemented their place as a leading biomass boiler manufacturer. They have an extensive range of biomass boilers that can run on wood logs, pellets or chips.

When comparing biomass boilers, it's important to consider the output, efficiency, warranty and potential cost.

    • Output: Installing a boiler with a suitable output rating for the heating and hot water demands of your home is essential when comparing replacement boilers. Output rating is measured in kilowatts (kW) and if it's too high for your home then your heating bills will shoot up. Too low, on the other hand, and the heating system will fail to meet the demands of your property.
    • Efficiency: As a renewable heating system, biomass boilers are highly efficient and will help to lower your carbon footprint (if you're replacing a gas or oil boiler). Each boiler has its own efficiency rating which equates to the amount of fuel it's able to convert into usable energy.

Froling biomass boilers are all over 90% efficient and receive an A+ rating. This makes them highly efficient and could potentially lower your energy bills as a result.

  • Warranty: A warranty period will see that you're protected by the manufacturer in the event of fault following the installation. Froling biomass boilers are available with a warranty of up to 5 years – the length varies depending on the manufacturer's terms and conditions.
  • Price: The potential cost of a new heating system is likely to play a big part in your final decision-making. Compared to gas and oil boilers, biomass heating systems have a higher price tag attached to them. However, it's worth looking at the long term costs involved as biomass fuels are inexpensive compared with gas and oil.

Froling biomass boiler fuels

Biomass boilers are diverse heating systems that can be fuelled by different forms of wood. These include wood logs, pellets and chips and Froling offer biomass boiler ranges that can run on any of these fuels.


Wood logs are the largest biomass fuel and will need to be manually fed into the boiler when you want heating. When purchased from a supplier the logs should have low moisture content. Wet logs would burn inefficiently as well as producing vast amounts of tar and soot.

If you live near a woodland area then you could potentially heat your home for free by sourcing logs yourself. Having said this, remember that low moisture content is essential.


Pellets are made from compressed sawdust and can be automatically fed into the boiler via a hopper.

Wood chips

Wood chips are tiny bits of wood that have been through a chipper. Thanks to their size, wood chips can also be automatically-fed into the biomass boiler when the heating is needed.

As well as biomass boilers that run on each of these fuels, Froling have developed dual biomass boilers that can be fuelled by both wood logs and pellets.

Froling log wood biomass boilers

Available in output ratings from 15 kW up to 60 kW, there's a suitable log-fuelled Froling biomass boiler for almost any home. As well as models with different outputs, the units are available in various sizes to help make for a flexible installation.
