KWB Biomass Boilers: Premium Austrian Engineering for UK Homes

KWB Biomass Boilers are one of biomass boilers brands which Proadvance Ltd support in England and Wales.
Proadvance Ltd from Reading in Berkshire is a registered and certified service of KWB biomass boilers in the UK. We offer repairing, service and periodical maintenance of KWB biomass boilers.
KWB biomass boilers are becoming more popular boilers in the UK and from this year we are a certificated service for that boilers.

When it comes to biomass heating, few names command as much respect as KWB. Standing for Kraft und Wärme aus Biomasse (Power and Heat from Biomass), KWB is an Austrian manufacturer globally renowned for setting the gold standard in renewable heating technology.

If you are looking to transition away from fossil fuels to a sustainable, carbon-neutral future without sacrificing comfort or reliability, a KWB boiler is one of the finest investments you can make for your UK property.

The KWB Product Range

Whether you have a compact family home, a farmhouse, or a commercial premises, there is a KWB solution designed to meet your heating needs:

KWB Easyfire (Pellet Boilers): Ideally suited for most UK residential homes, the Easyfire range is compact, quiet, and incredibly clean. Wood pellets are automatically fed into the system, meaning the boiler runs much like a gas or oil equivalent—you simply set the temperature, and the boiler does the rest.
KWB Multifire (Wood Chip & Pellet): Perfect for larger properties, estates, or businesses with high heat demands. The Multifire is a rugged all-rounder capable of burning wood chips or pellets. It features the patented KWB crawler burner, which handles fuel flexibility with ease, ensuring continuous operation even with varying fuel qualities.
KWB Combifire (Log Wood & Pellet): The ultimate hybrid. This system allows you to burn traditional log wood when you have the time and supply, but automatically switches to pellet mode when the logs burn out or if you are away from home.

Smart Technology: “Set and Forget”

One of the biggest misconceptions about biomass is that it requires hard work. KWB dispels this myth entirely. Their boilers feature fully automatic cleaning systems that keep the heat exchanger and burner clean, maintaining high efficiency and reducing maintenance to a minimum (often just emptying the ash bin a few times a year).

Furthermore, with the KWB Comfort 4.0 control platform, your heating system is fully connected. You can monitor and control your heating remotely via smartphone or tablet, ensuring your home is warm before you even walk through the door.

Why Choose KWB?

KWB is synonymous with innovation and build quality. Manufactured in Styria, Austria—the heartland of European biomass technology—these systems are designed to last for decades. Unlike cheaper alternatives, a KWB boiler is built with heavy-duty components and sophisticated combustion technology that ensures maximum efficiency (often exceeding 90%) and ultra-low emissions.

For the UK homeowner, KWB offers the perfect balance of eco-friendliness and modern convenience.

Everything you need to know about KWB biomass boilers

At this place, we’ll uncover every information is worth to know about of KWB biomass boilers, addressing common concerns, and providing valuable insights to help you make an informed decision.

How do KWB biomass boilers work?

KWB biomass boilers operate on a simple yet ingenious principle: converting the energy stored in biomass fuel into heat. This process begins with the combustion of the fuel, typically wood pellets, chips, or logs, within the boiler’s combustion chamber. The heat generated during this process is then transferred to a heat exchanger, where it warms the water or air circulating through the system.
1. Fuel Storage and Feed System: KWB biomass boilers are equipped with a fuel storage area, often a hopper or silo, where the biomass fuel is stored. An automated feed system transports the fuel from the storage area to the combustion chamber, ensuring a consistent and controlled supply.
2. Combustion Chamber: At the heart of the KWB biomass boiler lies the combustion chamber, where the biomass fuel is ignited and burned. This chamber is designed to optimize the combustion process, ensuring efficient and complete burning of the fuel.
3. Heat Exchanger: As the fuel burns, the heat generated is transferred to the heat exchanger, typically a series of tubes or plates. Water or air circulates through these tubes or plates, absorbing the heat and distributing it throughout the heating system.
4. Control and Monitoring System: Modern KWB biomass boilers are equipped with sophisticated control and monitoring systems that regulate various aspects of the boiler’s operation, such as fuel feed rate, combustion air supply, and heat output. These systems ensure optimal performance, efficiency, and safety.
By understanding the fundamental principles behind KWB biomass boilers, we can appreciate the engineering prowess and attention to detail that goes into designing these efficient and environmentally friendly heating solutions.

Service and maintenance for KWB biomass boilers

Proper service and maintenance are essential for ensuring the longevity, efficiency, and safe operation of your KWB biomass boiler. Regular maintenance not only helps prevent potential issues but also optimizes performance, reducing energy consumption and associated costs. Here are some key aspects of service and maintenance for KWB biomass boilers:

Manufacturer’s Recommendations: Always follow the manufacturer’s recommended maintenance schedule and procedures. KWB provides detailed guidelines specific to each boiler model, outlining the frequency and scope of maintenance tasks.
Professional Service: While some basic maintenance tasks can be performed by the owner, it is highly recommended to engage the services of a qualified and trained KWB service technician for more complex maintenance and repairs. These professionals have the expertise and specialized tools to ensure proper maintenance and troubleshooting.
Routine Cleaning: Regular cleaning is crucial for maintaining optimal performance and preventing issues such as ash build-up, soot accumulation, and blockages. This includes cleaning the combustion chamber, heat exchanger, flue gas passages, and ash removal systems.
Fuel Quality Monitoring: Monitoring and maintaining the quality of the biomass fuel is essential for efficient combustion and minimizing emissions. Ensure that the fuel meets the manufacturer’s specifications for moisture content, size, and composition.
Combustion Air Supply: Proper combustion air supply is vital for complete and efficient fuel combustion. Regularly check and clean the air intake systems, ensuring unobstructed airflow.
Flue Gas System Inspection: Inspect and clean the flue gas system, including the chimney or exhaust stack, to prevent blockages and ensure proper draft and venting.
Control System Calibration: KWB biomass boilers are equipped with sophisticated control systems that may require periodic calibration and software updates to maintain optimal performance and incorporate any necessary adjustments or improvements.
Wear and Tear Monitoring: During maintenance visits, technicians should inspect for signs of wear and tear on critical components, such as augers, motors, and seals. Timely replacement of worn parts can prevent more significant issues and downtime.
Documentation and Record-Keeping: Maintain accurate records of all maintenance activities, including dates, tasks performed, and any issues or repairs. This documentation can help identify patterns, track performance, and facilitate future maintenance planning.

By adhering to a comprehensive service and maintenance program, you can extend the lifespan of your KWB biomass boiler, optimize its performance, and ensure a reliable and efficient heating solution for years to come.

Financial Benefits and UK Grants

Switching to a KWB biomass boiler isn’t just about saving the planet; it’s about future-proofing your finances. By moving away from volatile oil and gas markets, you gain energy independence using locally sourced fuel.

Additionally, KWB boilers are MCS-certified, making them eligible for UK government incentives such as the Boiler Upgrade Scheme (BUS). Eligible UK homeowners can currently apply for a grant of up to £5,000 (and potentially more depending on current legislation changes) to offset the upfront cost of installation, making premium Austrian technology more affordable than ever.

Planning to buy an KWB boiler, you can apply for grant from government and this is very important for everyone who want to install any biomass boiler.
You should know that KWB boilers are Renewable Heat Incentive compatible, which means they are eligible for government funding.
