The hot air duct from the top of the boiler can be varied to incorporate a number of different heating circuits when connected to spiral ducting. It produces hot air at 120°C up to 22m3 for our 130Kw boiler.

This range is one of the most highly efficient available. At 92% heat efficiency it burns off all the gases and has a minimal ash output. They can take logs from 500mm to 1000mm long and 6" to 10" diameter depending on the size of boiler.

Using the latest downdraft technology, this gasification boiler burns all the gases produced during the normal burning process, therefore allowing minimal CO2 to be released into the atmosphere. The secondary burning chamber burns gasses at up to 1200 degrees centigrade. Regulated by a digital display panel which controls the ventilator fan, this enables the boiler to be 92% efficient. The boiler has a large log chamber which holds enough wood for up to 12 hours burning. The boilers are available in the following sizes 18, 25, 40, 60, 80, 80+ & 130kW.

The boilers are exceptionally economical. A 40kW boiler typically uses a similar amount of wood as a conventional log stove but at 92% efficiency it provides infinitely more space heating. All our hot air blowers are designed to burn softwood or hardwood between 15% and 20% moisture content. It is advisable to use softwood for batch burning only or to use as a mix (maybe 15% maximum) with hardwood for creating an ember layer when running the boiler continuously where for large periods of the time the boiler is in slumber mode. Even if the softwood is below 20% moisture content.

It is not ideal to use full loading chambers of softwood and then run the boiler continuously in this situation. As the softwood is resinous you will have very low flue gas temperatures when the boiler is slumbering for long periods of time and this can lead to a build up of pitch inside the heat exchange tubes and on the inside of the flue. It is possible that the turbulators in the heat exchanges tubes can become jammed as shown by the fact that the heat exchanger cleaning handle will no longer move and the overall efficiency of the boiler will be detrimentally affected. Any treated wood (creosote, paint), MDF or chipboard should not be used in our log boilers due to the carcinogenic emissions.

Depending on your source of wood this boiler offers fantastic savings over conventional systems. We believe the Angus Orligno 600 hot air blowers to be exceptional value for money.

Here are some of the benefits of the Angus Orligno 600
- Typically 20 to 35% heavier than others in its range as they are manufactured with thicker boiler steel plate for increased wear resistance/life expectancy (our boiler has an 8mm inner and 4mm outer as opposed to 5mm inner and 3mm outer boiler steel plate).
- They have one of the highest heat efficiency ratings (92% as opposed to 85% standard) for a hot air blower allowing a longer burn cycle and reduced wood fuel consumption.
- Larger combustion chamber volume than others in its range allowing a larger wood fuel load.
- Larger log length from 500mm for 18kW to 1000mm Long for 80kW.
- Ability to burn all types of wood and handle logs up to 10" Diameter.

Expected running costs are less then half of that of gas or oil. Please have a look at our case study
