Frequently Asked Questions...
Why do I need my Biomass Boiler sweeping?
'Soot' is the byproduct of an incomplete combustion within the Biomass boiler. As the fuel (pellets, wood chip or logs) burns, it breaks up into small particles; in the right conditions, these particles include soot, which will progress through the boiler to the flue, it will then settle and also stick to the internal lining of the Biomass flue system. This builds up over time whilst the boiler is operational and coats the lining, with the loose soot falling to the base of the twin wall flue system. This in turn, if not attended to by an appropriately trained chimney sweep will start to cause problems for your Biomass system, with large build ups restricting the flow of flue gasses out of the chimney, leading to problems that would cause the boiler to become inefficient or possibly stop it working at all.
How often do I need my Biomass Boiler sweeping?
The frequency will depend on a number of factors which include the type of fuel used, appliance, duration of use, moisture content of the Biomass fuel used, and the type of flue system you have. NACS / HETAS guidelines recommend a minimum of carrying out one sweep per year for a Biomass appliance. When we visit we will advise if you require more frequent visits for sweeping.
Other domestic appliances should be swept in accordance with the following guidelines:
Smokeless fuel: At least once a year
Wood: Quarterly when in use
Bituminous coal: Quarterly when in use
Oil: Once a year
Gas: Once a year
What should I do to prepare for my Biomass Sweeping visit?
PLEASE ENSURE THE BIOMASS BOILER IS TURNED OFF THE NIGHT BEFORE OUR VISIT, during the downtime your thermal store should be able to cope with demand. In general we will also need a clear passage to the Biomass Boiler and adequate space to work in. Please clear items from around the Boiler and flue system.
Why should I use a NACS Trained & HETAS Approved Chimney Sweep?
NACS Chimney Sweeps undertake a rigorous training course and have to successfully complete a full assessment prior to becoming a NACS Member. All NACS Members must hold valid insurance for Chimney Sweeping, of which they provide a copy of to the Association on an annual basis. They must also have the correct equipment to be able to undertake the job which is checked at the time of their assessment - NACS.org.uk
By using a HETAS Approved Sweep you can be confident that a sweep has obtained the necessary training to safely sweep the chimney and
Has the ability to make an informed choice - HETAS.co.uk
