NEWS : Windhager Wood Pellet Boiler Installed, Haddington, Edinburgh

Charlmers & Co are chartered surveyors and architects based near Edinburgh. They has just installed a Windhager BioWin wood pellet boiler in to their Georgian office building. The building was previously the British Linen Bank, and the old stone vault has now been converted into the pellet stove for the boiler. With a large external hopper feeding the Windhager wood pellet boiler makes it one of the first of its kind in the UK. The installation of the large pellet store will mean loading the wood pellet boiler manually will not be required. Alliteratively, a pellet tanker will make delivers several times a year to fill the store. A redundant hearth and flue was adapted for the Windhager wood pellet boiler to use. The BioWin is linked to out door thermostat which monitors the exterior temperature. Based on the settings of the pellet boiler, it will monitor the exterior temperature and provide enough heat without wasting fuel pellets.

The Windhager BioWin wood pellet boiler can provide a heat output ranging from 3-78KW. The BioWin range also features automated cleaning features of the burn pot and heat exchanger. Ash removal from the burn pot into the ash bin is also automated. The integrated computer display on the boiler will provide messages on the next time ash removal is required. The Windhager boiler can also be combined with other heat sources such as solar thermal. The clients have stated that despite the cost of the Windhager BioWin boiler exceeding the usual costs of a oil or gas system, using the biomass incentives in place, substantial savings were made. For example, almost half of the total cost of the installation was funded by the Forestry Commission under the Scottish Biomass Heat Scheme. The remainder of the costs were covered by an interest free loan from the Energy Saving Trust. The clients are very happy with the Windhager BioWin wood pellet boiler due to the environmental benefits, and how they are helping reduce the strain on the earths finite natural resources.

Highly Automated Wood Pellet Boiler and Possible Complications

The Windhager wood pellet boiler range is focused on increasing process automation to reduce required maintenance. Under the correct circumstances this automated features work perfectly well. However, changes in fuel ash content can cause these automated features issues. Also the Windhager wood pellet boiler range features a drop down burn pot. Drop down burn pots as you will see from the pellet stove and boiler guide are the most susceptible to combustion complications such as increased ash content and clinker formations. For example, sometimes due to the high efficiency of a pellet fire and the temperatures the fire exceeds the ash may begin to melt. When this happens the ash forms a solid glass like mass known as a clinker. Ash removal from a drop down burn pot is carried out purely by the movement of the combustion air. However a clinker has an increased density and weight compared to loose ash, therefore the combustion air will not remove the clinker, which will remain in the burn pot. This will eventually cause the boiler to fail.
