How often should my biomass boiler be serviced?
Regular servicing is crucial for optimal performance and reliability. Typically, we would recommend a minimum of 2 services per year, but the frequency may vary based on the manufacturer's guidelines and usage patterns.

What are the signs that my biomass boiler needs servicing?
The main indicator is boiler operation hours and kWh on the meter and length of time since last service. However, if a service is overdue, indicators such as reduced efficiency, higher than usual exhaust gas temperatures, unusual noises, increased fuel consumption, or error codes on the boiler display would mean a service was required as a matter of urgency.

Do I need to turn off my biomass boiler before a service?
We require boilers below say 500kW need to be switched off at least 24 hours before your engineer arrives on site to allow the system to cool down. Larger boilers may need significantly longer. You will be provided with instructions during the scheduling process, if required.

How long does a typical biomass boiler service take?
The duration can vary based on the complexity of the system and any issues found during the service. A routine maintenance check may take a full day completed by one engineer, while repairs or more extensive work could take longer. Larger boilers may require a team of engineers over a number of days.

What is included in a standard biomass boiler service?
A standard service typically include cleaning, lubrication of moving parts, testing safety features, inspection of components, check and calibration of sensors, service of the control panel, checking of fan impellors, visual checks on the boiler and measuring water quality. The boiler would be fired during the service and performance and boiler efficiency would be measured, monitored and optimised.

Is there anything I should do before the service appointment?
Switch the boiler at the pre-arranged time, clear the area around the boiler for easy access. If there are any specific issues or error codes or known issues with the boiler, please discuss this with the BBSM technical team well in advance of the service so we can ensure the service engineer has additional parts and components that may be needed, to avoid repeat visits.

How can I prevent breakdowns between services?
Follow the manufacturer's guidelines for operation and maintenance, including regular cleaning and fuel quality checks. Report any unusual performance issues promptly to address them before they escalate. Often an issue can be helped through remote technical advice if addressed early.

What is the expected lifespan of a biomass boiler, and can maintenance extend it?
A high-quality biomass boiler with good maintenance should have a life span of over 20 years. Regular servicing is a crucial factor to the longevity of the system.

What are the service requirements for the RHI?
If you have a boiler receiving RHI payments, you must have your boiler serviced by a biomass service provider accredited under HETAS MCS040 at least once per year. The details of the service must be recorded and up-loaded to the HETAS portal. BBSM Ltd was one of the first companies in the UK to achieve HETAS MCS040 accreditation.

What is the Non-Domestic Renewable Heat Incentive (RHI)?
The RHI is a government support scheme for commercial and industrial biomass boiler systems. It was launched in November 2011 and works by paying a subsidy to the biomass boiler owner for heat used (kWh per year) over a 20-year period.

Is the RHI still open to new applications?
No, the scheme closed in 2021. However, new projects can still benefit from the RHI as Ofgem have relaxed rules about moving and transferring RHI tariffs. There is currently many RHI tariffs for sale and transfer which could give any new biomass boiler project a very valuable income stream. Please speak to BBSM Ltd about what tariffs we currently have available.

I already have a biomass boiler accredited under the RHI scheme, but the boiler needs replacing. Can I replace the boiler and still retain my RHI income?
Yes, absolutely. The RHI now allows boiler replacement. You can replace an existing biomass boiler with a new high efficiency biomass boiler system. RHI allows a site to change boiler manufacturer/make and also change the size of boiler e.g. if a site had a 199kW boiler, but the site now requires a larger heating capacity the site could replace with say a 300kW boiler and retain the RHI tariff value and remaining period. BBSM Ltd specialise in boiler replacement under RHI. Please speak to BBSM Ltd about options.

I already have a biomass boiler accredited under the RHI scheme but am moving premises. Can I move my biomass boiler and still retain the RHI?
Yes, absolutely. The RHI now allows boiler relocation. BBSM Ltd specialise in moving biomass boilers and re-installing and commissioning.

Does the non-domestic RHI cover residential dwellings?
This might sound contradictory, but yes, the non-domestic RHI includes “District Heat Networks” where two or more domestic dwellings are heated via a single biomass boiler house connected to the residential dwellings via pre-insulated underground heat main. This is a very common solution in mainland Europe and is becoming more common in the UK. BBSM Ltd are currently working on a number of DHN projects.

I need support with an existing RHI application/payment claim or I need support on a new biomass boiler installation. Can BBSM Ltd help?
Yes, absolutely. BBSM Ltd staff have a decade of experience on “everything RHI” and also work with a number of leading consultants to offer comprehensive support, whatever your needs.

I have a Biomass Boiler with RHI tariff. However, I no longer need or want to operate my biomass boiler and looking to sell the biomass boiler with RHI tariff. How do I do this?
Please speak to BBSM Ltd. We have bought a number of RHI tariffs recently and would be interested in discussing buying the tariff. We have also brokered a number of deals matching sellers of RHI tariffs with new biomass boiler installations.

What is a biomass boiler, and how does it differ from traditional heating systems?
Unlike traditional heating systems that rely on fossil fuels like oil or gas, biomass boilers utilise renewable and sustainable resources. These boilers operate by burning biomass fuel, releasing energy that is then used to warm spaces or produce hot water. One of the key distinctions from conventional systems is the carbon neutrality of biomass.
