Frequently Asked Questions
A boiler that can burn woodchips, wood pellets or logs to waste agricultural materials such as straw, grain husks, olive kernels, rice and the dust from any of these including sawdust.
Yes. Unlike Oil boilers which only require annual service, Biomass can require weekly inspections; if even only visual, plus an annual service. If the boiler does not have automatic self cleaning, regular cleaning of the turbulators is required using a flue brush.
Yes, just like any other boiler can be replaced. But since Biomass Boilers operate at higher temperatures, they have to adhere to the different building regulations.
Other than the boiler itself, you will generally need a store or a Silo if your boiler isn't a log boiler. You will then need a mechanism to transport the fuel from the Silo to the boiler. This can be either an Auger or Vacuum unit depending on how far away the boiler is away from the store. The last part you will need is a Buffer Tank, for efficiency and system protection.
This is one of the benefits of adding a Buffer Tank to your heating System. The hot water loads in the summer are very small compared to the size of the boiler. Having a Buffer Tank will mean that the boiler will only need to come on once or twice in a week as the hot water only is drawn from the tank.
Biomass boilers like to be worked continuously, that is when they operate at their most efficient. Unlike gas or oil boilers they cannot be turned on and off. This is another reason why they must be connected to a Buffer Tank. This will help with boiler cycling and deal with demands that are lower than the boilers nominal output.
