Commercial Biomass Boiler Maintenance & Servicing

We carry out boiler service and maintenance for many of our wood chip and wood pellets customers. Like any other boiler – or even your car – an annual service is important to keep the system running efficiently.

The importance of servicing your biomass system 

  • An annual service is a condition of your RHI accreditation  
  • Increased boiler efficiency, leading to higher RHI payments and lower fuel bills  
  • Fewer breakdowns

Annual Commercial Biomass Boiler Service Details

Accredited Engineers

Our engineers are accredited to work on several brands of biomass systems including ETA and Gilles, and we are planning to increase the number of brands we cover. This is important if you need to make a claim under a guarantee on any faulty boiler parts. If we are not accredited to service the brand of boiler installed at your location, we will do our best to locate another installer to help you. 


Remote Monitoring

If you have a broadband connection at your property, we can install a device which allows our computers to monitor how well your biomass system is working. So, if your system develops a fault, we may be able to diagnose the issue within a few minutes of the problem arising. In some instances, our engineer can solve the problem without you having to pay for a call-out charge. 

With our remote monitoring gadget in place, you will be able to view the same real-time information as we see, if you wish to do so. All you need is a smartphone, tablet or desktop computer. 

Even when you’re away from your property, the app will give you information such as how many pellets are in your store, so you’ll always know whether you need to order more fuel.

When selecting PBE to install our 1MW solution, we were very impressed with their quality of workmanship, which we wanted to ensure reflected the facility. Their longstanding relationship of over 10 years with Bluestone National Resort meant that we knew they had the experience to deliver our solution.

PBE completed our installation in less than 10 weeks from conception to completion. We now have a well designed and high-quality system fuelling our kiln. We received amazing support with any queries we had right from the start to the present day.
