What is a biomass boiler?

Biomass boilers are boilers that are designed to burn logs, wood chips and pellets using a process of direct combustion.

Because biomass boilers burn a renewable fuel source, so they are considered to be environmentally friendly. This is because biomass fuel is sourced from wood from quick growing trees. When wood or remnants from these trees are burnt, they release the same level of carbon dioxide that they took in when growing, meaning that biomass is considered a carbon-neutral fuel.

Design & Technology

The Vitoligno series of biomass boilers features a range of fully automatic wood and pellet boilers with a broad spectrum of use ranging from low energy houses to buildings with larger heat demands.

It offers versatile and flexible supply system options for almost any application and stands out on account of its compact design which is ideal for limited room heights. In the output range from 2.4 to 48 kW, the pellet boiler modulates with a ratio of 1:3 and features impressively low energy consumption.

Our range includes pellet only boilers as well as boilers designed for both wood and pellets, making them an ideal choice for those looking for greater fuel flexibility.

Heating with wood

Heating with wood – the most natural fuel in the world

The rising cost of fossil fuels, and growing environmental awareness have been steadily increasing the demand for renewable forms of energy. A wood boiler is a good alternative to heating with oil or gas. Alongside environmental considerations, there are also economic reasons for relying on wood. As an indigenous fuel, wood is very cost efficient and not subject to extreme fluctuations.

Viessmann wood boilers are highly efficient and economical in their fuel consumption. They are suitable both as the sole heat generator and as a supplement to oil or gas boilers. By installing a wood boiler, spending on oil and gas is reduced significantly so the boiler starts paying for itself almost immediately.

You will be making a positive contribution towards the sustainable protection of our climate, because heating with wood is CO2 neutral. This means that only as much carbon dioxide is released into the atmosphere as the wood absorbed while it was growing.

Logs or pellets: The Viessmann range has everything covered

Whether as an auxiliary or complete heating system, using logs or pellets, Viessmann offers the full product range for heating with wood. By choosing a Viessmann wood boiler, you'll always be on the safe side. There are plenty of good reasons for choosing this type of boiler:

  • Highly reliable
  • Long service life
  • Convenient DHW and central heating
  • Independence from oil and gas
  • Cost savings through economical energy consumption
  • Pellet heating systems and solar technology make for an ideal combination

Domestic RHI

Domestic Renewable Heat Incentive (Domestic RHI) Eligible

As Vitoligno biomass boilers use a sustainable fuel source, they are eligible for the UK government’s Domestic Renewable Heat Incentive (Domestic RHI). As part of the incentive, you will receive quarterly payments for seven years in return for the amount of green, renewable heat which your biomass boiler produces.

Futureproof through low emission levels

With their low emission levels, the Vitoligno range of biomass boilers will continue to comply with strict environmental regulations for biomass heating systems long into the future. Their long burnout time ensures complete combustion with extremely low emissions.

Vitoligno biomass boilers are particularly economical and adapts their output precisely to the current heat demand.

Fully automatic ash removal 

Selected Vitoligno biomass pellet boilers feature an efficient automatic ignition with lower power consumption and fully automatic ash removal from the sliding frame and heat exchanger for added convenience.

Intelligent control and comprehensive equipment range

The integrated Ecotronic control unit can combine renewable technologies by directly connecting to a solar thermal system, a water heater and a direct heating circuit.

In combination with the Vitotrol 350-C (option), Vitoligno pellet boilers can also be controlled from the living space. With the 5-inch touchscreen in 16:9 format, operation could hardly be easier. The clear menu makes operation easy, as does the readable display, which can show heating data including heat curve graphics.The system can be extended to include up to 24 control loops using control modules. These can be used for heating circuits, DHW heating or in conjunction with a district heating supply line. The Vitotrol 350-C can also be used as a cascade controller for up to four wood boilers.

We also provide equipment which is tailored to the Vitoligno 300-H, meaning Viessmann offers a complete solution from one source. These include systems for the storage and supply of pellets and woodchips and an intelligent buffer management system for an efficient stratification of the hot water.
