Biomass boilers and stoves should be kept clean and swept regularly to remove ash. Ash quantities are generally very low (less than one per cent of fuel volume), but you will still need to empty the ash bin of a wood burning stove or boiler. This is likely to be weekly and never more than once a day. A log fire requires ash removal before every use.

Some appliances, particularly boilers, have self-cleaning systems which will collect ash from the combustion grate and the heat exchanger tubes. If there is no automatic ash cleaning mechanism in place the boiler will need to be shut down periodically so that this can be done by hand. If the ash is not cleaned out regularly, it will build up and adversely affect combustion conditions, which can lead to boiler failure and shut down. Some boilers have a mechanism for compressing the ash which reduces the number of times the ash bin needs to be emptied.

With automatic ash removal and cleaning of the heat exchanger the only other maintenance requirement will be occasional ash removal and an annual maintenance check. If you have a wood burning stove or boiler the chimney and flue pipe must be swept regularly to remove all soot deposits and prevent blockage. HETAS recommend that this “should be done at least twice a year, preferably before the heating season to check that the flue has not been blocked by bird’s nests for example and also at the end of the heating season to prevent soot deposits from resting in the chimney during the dormant period”.

 Service Agreements

Service plans are vital to the smooth running and performance of any system. We offer comprehensive Biomass maintenance and servicing contracts with an ongoing commitment to ensuring the system operates efficiently and at its optimum performance. Service plans / agreements are for commercial systems only as they require more regular maintenance then a domestic installation.

For domestic systems contact us to arrange an annual or six month service visit, once we have you’re details on our system it will prompt us when your system is due another visit.

*Evidence of a suitably maintained system is a requirement for eligibility under the RHI scheme

With a Planned Maintenance Agreement, you…

  • Save money on heating
  • Help prevent breakdowns
  • Restore lost capacity
  • Return efficiency to peak performance
  • Stay in compliance with your manufacturer’s warranty
