There are a number of things that you need to consider before installing biomass boilers. Some of the factors that you need to consider include fuel supply, delivery of fuel, storage of fuel as well as easy access. While there are a number of biomass systems available on the market today, you need to choose one that produces low emission by burning the supplied fuel at a fast rate and at a high temperature.
Also, there are a number of models available today and some of the high-end models have a lot of features to make it comfortable operating the boiler. So, you need to choose the right system that is within your budget and has all the features that you need.
One of the issues with using biomass as fuel is that the biomass systems are not well-suited to allow modulating the output whereas output can be easily modulate in various other heating systems that use fossil fuels. However, there are some new models that can decrease the output by up to 70% of the maximum output. Therefore, it is important that you choose a system that allows you to modulate the output.
Another important thing you need to consider is the seasonal variation. There will always be those super cold days when you may feel the need to have an extra system installed for keeping your house warm. Similarly, you will need much lesser output in the summer months.
Therefore, experts recommend supplementing the biomass boiler with a small gas boiler. This gas boiler can be used along with the biomass boiler during those super cold days to provide that extra warmth. Similarly, it can be used to provide the low level output needed for summer months.
Some of the biomass systems have an additional insulated storage container to allow the boiler to burn at its maximum efficiency. In these systems, this big water container is used to store hot water that is used when required. This huge water storage container allows boiler to be operated at maximum output which enhances efficiency.
You also need to take into account the supply of fuel when you plan on installing a biomass system. If local supply of wood fuel is easily available with wood at less than 35% moisture content, it means that you can get away by installing a smaller and ultimately, cheaper system. As fuel is easily available, you will also require less storage space and thee are less chances of fuel composting during storage.
You also need to pay attention to the design of the biomass fuels store keeping in mind the delivery as well as extraction of the fuel and proper access for maintenance. Due to the low energy density of biomass, a large volume needs to be stored on-site to ensure that there is sufficient reserve available. Therefore, sufficient space needs to be available to ensure that there are no issues in supplying fuel to the boiler.
As far as installing a biomass system is concerned, it is important to keep in mind that it is more of a lifestyle choice. It is a choice that helps in keeping the planet green and reducing your carbon footprint. While there are a number of benefits of installing a biomass system, you also need to choose the right system and the right boiler installers to ensure that the system keeps working without any issues for a long time to come.
One other important thing you need to consider is that sometimes, the installers do not quote the full cost of installation. While they may quote price for the actual system, you may also have to pay for insulated pipes to deliver heated water to your property and various other such things such as digging trenches. So, you should ask the installer to provide you a quote for absolutely everything needed for the system to work.
