The Importance of Servicing Your Biomass Boiler

There is one main reason you should service your biomass boiler on a regular basis – it will save you money in both the short-term and the long-term!

Reasons why servicing your biomass boiler on a regular basis is imperative:

⦁ It is a requirement of RHI to service your biomass annually.

⦁ An annual service offers peace of mind and keeps both you and your property safe.

⦁ Biomass boiler warranties are only valid if the boiler has been serviced annually by an appropriate accredited engineer.

⦁ Your insurance may refuse to pay-out in the event of a claim if you haven’t had your boiler serviced each year.

⦁ Annual servicing increases operational efficiency – saving you money on your fuel bills.

⦁ In most cases, boilers that are serviced annually last longer.

As biomass boilers use solid fuel, they produce waste products including ash. Due to the combustion process of a biomass boiler, ash coats the steel surfaces it comes into contact with. When ash forms a coating on the heat-transfer section of a biomass boiler – heat dissipation and thermal efficiency are reduced. This results in more fuel being burned to attain the same amount of energy from the boiler. A strong indicator of a biomass boiler with reduced efficiency is an increased flue gas temperature.

Biomass boilers also contain lots of mechanical components that require regular lubrication, such as combustion air fan actuators and fuel extraction systems. Regular lubrication of these components ensure boilers run smoothly and efficiently.

Although most biomass boiler manufacturers provide basic information about servicing in their operator manuals, it is advisable to have your boiler serviced by a trained and accredited engineer. Not only will this validate your warranties and keep you in line with the terms and conditions of insurance policies, it will ensure your boiler is cleaned properly and running at its optimum efficiency. You will also have the peace of mind knowing that your boiler is safe.

Maintaining your boiler with a regular service is more cost-effective than calling out an engineer to repair a boiler that isn’t working because you failed to get it serviced properly. It is also a major inconvenience being without heating and hot-water – especially in winter!

So, a simple annual service means you will satisfy legal requirements and insurance companies, validate your warranty, give yourself peace of mind that your loved ones and your property are safe – and lower your energy bills!
