Biomass Boiler Service

GlenFarrow recommends annual servicing for biomass boilers and equipment and offer a Biomass Servicing package to all customers. While the key element of the Biomass Servicing package is the biomass boiler other parts of the system need to be maintained. It is also part of the Renewable Heat Incentive (RHI) conditions to have your boiler serviced, to continue to receive RHI payments, the equipment must be maintained in accordance with the Manufacturers specification. Your new boiler’s first service is free of charge.

Why do you need to have your boiler serviced?

An annual boiler service is essential to maintain your eligibility for Renewable Heat Incentive (RHI) payments. GlenFarrow recommend that all their boilers are serviced annually to ensure the most efficient operation, minimise the possibility of breakdowns and keep the boiler in a safe state for operation. The RHI Guidelines Volume 2: Ongoing Obligations & Payments, item 2.6 Maintenance of Equipment states “As an ongoing obligation, participants who own heat generating installations are required to maintain their equipment to ensure that it is working effectively. Ofgem requires equipment to be maintained in line with manufacturer’s instructions…..Participants will need to keep any evidence of maintenance work carried out, for example service receipts and to provide them with this evidence on request”. When we service any equipment we will provide full documentation for your records.

How often should a biomass boiler be serviced?

Boilers should be serviced annually. This regular process will ensure the boiler will continue to work at the optimum level, be safe and will help to minimise the possibility of breakdowns.

How long will my service take?

We recommend that you allow a full day for your biomass boiler service.

Arranging your biomass boiler service

We will work to minimise the downtime and to arrange a date which best suits you to ensure the minimum inconvenience. We will contact you to arrange a suitable date.

Be Prepared for Frost

Draining the System

The Biomass boiler and heating equipment are not frost protected. So if you aren’t using your boiler during the winter they should be drained down. If you have larger systems with several buildings, separate sections should be drained if not in use.

Before draining the boiler, the cold main should be isolated and the boiler feed from the header tank should be left on, in order to drain the header tank as well. All the pumps have to be switched off before starting to drain the system. This can be done by switching on the main electrical supply on the boiler and switching the main circulator(s) isolators next to them off, if the circulators are fed from separate connection.

The boiler can be drained through various drain points on the boiler. Please refer to your Operation and Maintenance manual for these (if in any doubt contact Wayne Flowers on 01775 722327). The door has to be drained separately from the boiler. Similar drain points can be found on every heating unit. The majority of the water within the system can be drained via the boiler, in order to avoid too much water being expelled within the premises heated.

Copper heating coils i.e. Log Dryer heating coils, FCU’s (Fan Coil Units) etc. have to be purged with dry compressed air stream, after the system is drained.

If there is a plate heat exchanger installed on the system, the section after the heat exchanger needs to be drained separately.

Re-filling the System

To refill the system follow the steps below:

  • Close the drain points;
  • Shut the valves on the boiler (valve at the back of the boiler and valve on the top of the boiler);
  • Open cold mains;
  • When the boiler is full, open flow valve (at the top of the boiler) and check if all the valves on the heating units and equipment are open;
  • Once the boiler stops filling up, open return valve (at the back of the boiler)
  • When filling stops again, switch the electric supply and the circulators;
  • To remove any air in the pipework quicker, switch the main circulator on and off in 1 minute intervals. Keep switching until you don’t hear a continuous gurgling noise from the pipework.

What is included?

  • Initial visual check, including applicable plant room.
  • Check of heat meter operation, including checking flow areas and return temperatures are correct with external devices, and any error codes present. Check and adjust safety devices i.e.PRV’s, AAV’s and flow switches.
  • Check and replace door and flue box, rope seals if worn
  • Check main temperature sensor against external device
  • Check for signs of leaks and repair if necessary
  • Check thermal insulation on pipework and repair if necessary. Check for rust.
  • Check pump operation and flow rates and clear any fault codes
  • Check door catch operation, grease hinges, check for wear and replace parts as necessary.
  • Check plate heat exchanger performance with external device and check for corrosion
  • Re-paint parts of Biomass Boiler as required
  • Clean the flue box and sweep chimney, scrape and clean chamber
  • Check the fan controller operation. Check fan(s) operation, clean as necessary.
  • Clean heating coils (if applicable)
  • Check for damaged cables and check chimney frame
