Windhager biomass boilers

Windhager biomass boilers have led the industry as effective, efficient and safe heating systems for over 90 years. Their range of biomass boilers includes models that can run on wood chips, logs or pellets and are available in a range of sizes to suit most properties.

The installation of a biomass boiler should follow a comparison of suitable models. To do this, you will need to take a close look at the output rating, efficiency, warranty and potential price of each model.

  • Output: When having a new boiler installed, it's essential that the output rating suits the heating demands of your home. An output rating is simply the power of the boiler – the higher the output rating, the more powerful the boiler.If you have a biomass boiler installed with an output rating that's too low then it won't be able to meet demand. The solution isn't to simply get the most powerful unit you can afford, however, because this could lead to your heating bills going up unnecessarily.

    A biomass boiler installer will be able to recommend the ideal output rating for your property based on your demand for central heating and hot water.

  • Efficiency: Ideally, your new biomass boiler will convert as much of the fuel into usable energy as possible. And the efficiency rating is the best way to see how well a boiler uses the fuel. It's displayed as a percentage and Windhager biomass boilers achieve efficiencies over 90% – a similar level to gas and oil boilers.
  • Warranty: In the unlikely event of a fault developing soon after the installation of a replacement boiler, you want to know that you're covered. And this is where the warranty period comes in. During the warranty period (2-7 years for Windhager biomass boilers) the manufacturer will cover the costs of repair if there's a fault. Always check the manufacturer's warranty terms and conditions so you know what they'll cover.
  • Price: Biomass boilers are typically more expensive than conventional gas and oil units. This shouldn't rule out the installation of a biomass heating system as the long term costs involved could help to save you money.

Windhager biomass boiler fuels

Depending on the model, biomass boilers can be fuelled by either wood chips, logs, pellets or a combination of these fuels.

Wood chips

When wood is passed through a chipper it's turned into wood chips and these can be used to fuel a biomass boiler. As they're smaller than wood logs, wood chips can be automatically-fed into the biomass boiler – saving you a job.

Wood logs

By far the largest biomass fuel, wood logs need to be manually-fed into a biomass boiler as and when heating or hot water is needed. Wood logs are abundantly available in wooded areas so if you have access to one then you could potentially reduce your fuelling costs to zero.

Wood pellets

Wood pellets are the most widely available biomass fuel available in the UK. They're small tube-shaped pieces that are made up of compressed biomass materials.

Wood pellets are the easiest to store as they take up the least amount of space. In addition, it's possible for the pellets to be automatically-fed into the boiler as and when heating and hot water is needed. This is opposed to you having to put the fuel into the boiler yourself, as is the cast with wood logs.

Biomass boilers manufactured by Windhager are available to run on any of these biomass fuels plus there's a log and pellet hybrid model.
