Wood Pellet Boilers

Wood pellets are a type of wood fuel, generally made from compacted sawdust. They are usually produced as a byproduct of sawmilling and other wood transformation activities. The pellets are extremely dense and can be produced with a low humidity content (below 10%) that allows them to be burned with a very high combustion efficiency. Further, their regular geometry and small size allow automatic feeding with very fine calibration. They can be fed to a burner by auger feeding or by pneumatic conveying.

Their high density also permits compact storage and rational transport over long distance. They can be conveniently blown from a tanker to a storage bunker or silo on a customer's premises. As the price of heating with fossil fuels increases, more capacity for pellet heating has been installed. At Glynns we sell wood pellets in 15 kg bags. Contact us today for a competitive price.

Wood Pellet Stoves

Stylish and Elegant is one way to describe the range of wood pellet stove in Glynns. We have a working model in our Claremorris store which serves two functions. It acts as a working display and it also heats the Energy Centre. Our stoves are Italian made and are available in a range of colours and styles.

  • This beautiful stoves are available with and without boiler.
  • The Boiler models can heat up to 13 radiators.
  • The a grant of up to €1,400 still available
  • Remote Controlled
  • Programmed to come on and go off

Wood Gasification

This heating system is perfect if you have access to large quantities of wood. The best woods to use are hard woods such as Ash, Oak , Beech, etc, etc which enables a longer burn time. Softwoods like spruce burn quicker and creat more ash waste. Moisture content in the material must be less than 25%; ideally 20% or less.

How does it Work?

Gasification is achieved in wood burning when gases released from the combusting wood are mixed with a regulated supply of oxygen to create a complete oxidation process. This results in extremely high combustion effiencies and minimal of ash waste.

Key features:

High efficiency
Due to the gasification process and unique heat exchanger design the Bio-tec achieves extremely high efficiencies; up to 91% on some models. So even if your wood comes for free you'll be storing and burning a lot less than with a traditional wood-burning boiler, stove or range.

Easy to load
The large combustion chamber and access door means that logs up to 500 mm in length can be used on standard domestic boilers. Log sizes of up to 700mm and 930mm can be used on higher capacity models.

Simple to start
All you'll need to start the Bio-Tec is a fire lighter and some light sticks. The Bio-Tec controller manages the rest of the start-up procedure making sure that the fire builds up as quickly and efficiently as possible.

Minimum of cleaning
In wood gasification most of the wood is combusted so that very little ash remains in the combustion chamber or flue. If the boiler ran at full power continuously it would only need to be cleaned every three to four days. In most cases the boiler will only be fired-up every few days so that cleaning will only be required every few weeks

Modern, user-friendly controller
The Bio-Tec boiler comes with an easy-to-use controller which manages the complete combustion process and regulates supply to the central heating system and hot water storage tank. An LCD screen on the controller displays key system information.

What fuels can I burn?

Only wood or wood briquettes with a maximum humidity of 20% can be burnt in the Bio-Tec boiler. And the lower the humidity the better the combustion efficiency.

Firebird CAS 2000 Accumulation tank

An accumulation tank must always be used in conjunction with the Bio-Tec wood gasification boiler to allow the boiler to operate in the most efficient manner. The official recommended sizing of accumulation tanks for solid fuel heating is a minimum of 50 liters of water storage for every 1 kW of rated boiler output. Hence for a 35kW boiler a minimum accumulation tank size of 1750 litres is need. To provide an additional safety level Firebird will be supplying a 2000 litre accumulation tank with the 35kW Bio-Tec boiler.

The Firebird CAS 2000 Accumulation Tank has been engineered to ensure highly efficient storage of the boilers thermal energy with the minimum of heat loss.
