How much will my biomass boiler installation cost?

Posted by FairEnergy . on 9 April 2014 at 7:30 am

The price of a biomass boiler can vary greatly. It ranges upwards from around £10,000 for a small domestic log system and from around £20,000 for a standard commercial installation heating two or more buildings. After making an initial enquiry to an installer you should expect to receive a telephone consultation, where an expert will talk you through the systems available and find one best suited to your individual needs.

Quotations for biomass installations should be unique to you and your property(s). Installers will take a number of key variables  into account when calculating an estimate. These tend to be broadly based around the following factors:

The type of boiler, which is determined by:

-   Type of fuel: biomass boilers run on a range of fuel types including log, wood pellet, wood chip and miscanthus.  It’s important to choose a suitable fuel based on the availability of the fuel source and your individual needs. These will depend up your building type and construction, storage space available, and how automatic you want the boiler to be.

-   Fuel feed: biomass boilers can be fed manually or automatically. Manual biomass boilers, where the wood is fed by hand, are cheaper but you will need to take into account the potential cost (and effort) of labour.

The size of the biomass boiler

-   This is defined by the number of buildings to be heated and their total overall size. In theory, the higher the amount of kW output needed to keep your premises heated throughout the year, the bigger the biomass boiler would need to be.

- Whether there is a need to have a backup oil boiler beside the biomass installation. An auto-connected back-up system is usually a necessity for larger schemes. 

- Whether a specialised control system is required to replace your existing controls. This can either be integrated with your existing system or used in replacement.  

Following an initial phone call, an installer will usually visit your property to assess your requirements in more detail and provide a full survey and formal proposal, which will work out a definitive cost and map out the relevant design work.  

Any quotation you receive should itemise all of the equipment to be used, stating what’s included and excluded. Common things that may or may not be in a quote and are worth bearing in mind as a potential additional cost include the delivery of equipment, electrical and construction works, submitting an RHI application to Ofgem and the removal of old boilers.

Biomass boiler systems typically cost more than oil or gas boilers. However, it is important to bear in mind the potential payback from the renewable heat incentive and ongoing fuel savings when requesting a quote. In terms of running costs, biomass compares very favourably with other fuels and you should save against solid fuel or electric heating costs. Wood prices are not anticipated to increase at the same rate as fossil fuel prices (at least in the short term).

I myself renders power plant management services. I would like to tell the honest answer. Yes' the initial investment for installing these  boilers are a lettle bit high but the power they produces is relatively cheaper.
