Viessmann Vitoligno 300-C

Vitoligno is a range of biomass boilers manufactured by Viessmann which includes models that can run on either wood logs or wood pellets. The Vitoligno 300-C runs on wood pellets and is fully automatic so you won’t need to manually feed the fuel into the boiler. The ash that builds up inside the boiler doesn’t even need emptying much compared to other boilers, just once or twice a year.

Thanks to a compact design, this appliance is able to fit in rooms that don’t have high ceilings. Even though, it’s one of the smaller biomass boilers around, it is still very powerful and is suitable for homes with larger heating demands. The unit is highly efficient and also has lower power consumption as it has automatic ignition, which will help you to save money on the bills.

Froling T4 Biomass Boiler

Froling’s T4 is a diverse biomass boiler in the sense that it can burn either wood chips or wood pellets. The boiler is simple to clean thanks as it automatically sends ash into an ash container, which can be easily taken out for the ash to be thrown away.

You can control your boiler and see how it’s performing from another room in the house by fitting a room console. If you’re out of the home, you can still keep an eye on your boiler by downloading the Froling app, which will alert you to any status changes.

Windhager LogWIN Premium

LogWIN Premium boilers is a range of 5 boilers with outputs ranging from 13-50kW to help you find the unit capable of meeting the heating and hot water demands of your home.

The boiler generates heating and hot water by burning wood logs which can be a maximum of 500mm long. Thanks to a large stainless steel combustion chamber, during the course of a year you will be refilling it about 100 times less compared to other biomass boilers that burn logs.

Grant Spira

Grant’s Spira boiler is a condensing unit which means that it captures some of the lost heat energy to maintain a high efficiency.

The appliance requires very little maintenance as they have a self-cleaning burner and heat exchangers. When stocking up on fuel, if you use an EN Plus Grade A1 wood pellet then they have low ash content which will further help to reduce boiler maintenance because the ash pan won’t need emptying as often.

Wood Logs, Pellets or Chips?

There are 3 different types of wood that can be used in biomass boilers, all of which require more storage than gas or oil. There are pros and cons to each so you’ll need to be sure about which one is best for your home before investing in the appliance.

Wood logs are the largest, which means that they can’t be automatically fed into the boiler by a hopper. This increases the manual workload required. If you live in an area where you can access wood logs freely, then you could soon have a free fuel supply.

Wood pellets are made from compressed sawdust and wood shavings. You won’t have anywhere near as much to do than with a boiler that uses wood logs as they take up less space and boilers that have a hopper can automatically feed them into the burner. You will need to be aware of the size, shape and moisture content that your boiler requires.

Wood chips are the cheapest option but aren’t as efficient. In many cases, wood chips can be sourced locally but it’s important to check that they are suitable for your biomass boiler. A boiler using this fuel may need checking more often than biomass boilers that burn one of the other types of wood. They’re also not as compact as wood pellets, making them harder to store.

Which Biomass Boiler Should You Buy?

Before even comparing the models we’ve looked at above, all biomass boilers are using a fuel source that’s highly sustainable, carbon neutral and cheap to run making them a valuable long term investment.

In terms of these boilers, there are some very reliable options whether you’d like to use wood logs, chips or pellets. Thanks to have a large combustion chamber, meaning that you don’t have to refill the boiler very often is a huge benefit of the Windhager LogWIN Premium. With a range of 5 boilers to choose from too, you’ll have a greater chance of finding the ideal boiler for your home.

If wood logs are too large to store around your home and you’d rather not be manually filling the boiler then the Vitoligno 300-C manufactured by Viessmann is completely automatic. So when the boiler needs refuelling it will be able to do this by itself, you’ll just have to ensure there’s a supply of fuel, which is required with any biomass boiler. While you’ll need somewhere to store fuel, you won’t need as much space for the appliance as many other models due to its compact size.
